Ordered so each task delivers a running slice the next task builds on. Source of truth for schemas is [DESIGN.md](../../DESIGN.md); source of truth for e2e behaviour is each project's `README.md`. - -- Make reports make sense and useful. -- Rename `run` to `trace` - -## Follow-ups - -- **skill-forge authoring loop** — Design drafted at [docs/developer/2026-06-07-A-skill-forge/design.md](2026-06-07-A-skill-forge/design.md): a new `skills/skill-forge/` skill that runs `skill-creator`'s authoring loop (draft → full scaffold → assemble/run/eval/report → refine against `improved>0 && regressed==0`) on `ailly-skill-eval`'s harness — generating the `patterns-eval` shape from a draft `SKILL.md` and vendoring it into `context/skills/`. v1 is the core loop only; iteration ledger, description-optimization loop, variance via a repeat axis, packaging, and an `ailly scaffold` subcommand are deferred. This is the bootstrap/loop half that pairs with the `ailly-skill-eval paired-skills split` follow-up above. **Next:** clear the `*DRAFT*` marker after review, then run planning to break out `SKILL.md` + `references/{loop,scaffold}.md` and the generation contract. Session: docs/developer/2026-06-07-A-skill-forge. - -- **configured source roots (external prefix allowlist)** — Option B from the external-prefix-block design (Session: docs/developer/2026-06-07-B-external-prefix-block). Once the `external` prefix-block kind (Option A) lands, replace per-block opt-out host paths with a project-level declaration of named external roots, resolved once at [Project::open](../../src/content/project.rs) into their own `PhysicalFS` mounts and referenced from prefix blocks by name (e.g. `@skills//SKILL.md`), with `..`-escape still rejected within each. Turns the sandbox from opt-out (any absolute host path) into an allowlist (only pre-declared roots). **Trigger:** a harness wants a named, sandbox-preserving cross-root reference, or the README's self-contained-folder claim needs the escape constrained. Closes the skill-forge design's derived-sync open decision ([2026-06-07-A-skill-forge/design.md](2026-06-07-A-skill-forge/design.md)) by removing the derived copy entirely. - -- **eval-program-outputs final review** — Once the `CheckerCall` side-channel, the per-conversation `program_outputs` accumulator in [src/knowledge/eval.rs](../../src/knowledge/eval.rs), and the `check_judge` `PROGRAM_OUTPUTS:` block in [src/knowledge/assertions.rs](../../src/knowledge/assertions.rs) are implemented and the feature test [tests/eval_program_outputs.rs](../../tests/eval_program_outputs.rs) passes, run `developer:refactor` + `general:review` over the full slice: confirm the empty-accumulator judge body is byte-identical to today's (a `check_judge` unit test with `&[]`), per-conversation isolation holds (two convs, distinct markers, an `eval.rs` unit test), `CheckerCall` captures stdout on the `Pass` path with redaction preserved, and that the inner assertion loop's explicit `Judge`/`Program`/`Script` arms left the remaining sync variants on the `_ => assertion.check(...)` arm. Session: docs/developer/2026-06-04-C-eval-program-outputs. - -- **patterns-eval no-key CI policy** — The live falsification step in [e2e/patterns-eval/ci.sh](../../e2e/patterns-eval/ci.sh) now hard-fails when `ANTHROPIC_API_KEY` is absent, against the insurance-claim convention of gracefully skipping the live half so keyless contributors still see the assemble half pass. The acceptance run uses the key in `e2e/patterns-eval/.env`; the broader policy for the no-key case is unresolved. **Trigger:** a contributor without API access needs the assemble half to pass in CI without the live half erroring. - -- **patterns-eval non-TypeScript checkers** — The three `check_*.py` checkers target TypeScript only, because the invocation prompts pin TS (via [e2e/patterns-eval/context/AGENTS.md](../../e2e/patterns-eval/context/AGENTS.md)). If a future sweep pins a different output language, each checker needs a language branch or a per-language sibling. **Trigger:** a patterns-eval sweep pins a non-TS output language. - -- **patterns-eval structural-checker fragility** — The live falsification gate in [e2e/patterns-eval/ci.sh](../../e2e/patterns-eval/ci.sh) passes but with a thin, variable margin: `improved` ranged 1–3 across live runs and the gate survives largely on the LLM-as-judge assertion. The regex/heuristic `check_*.py` checkers reliably discriminate only `emitting-logs`, and even there a capable model's idiom variation (a bare `name:` event field, `Brand<>` helpers, expression-bodied arrow constructors) intermittently fails the invocation arm. `newtype` is an intentional null result (both arms pass). Decide whether to (a) lean the structural assertion on the judge and demote the script checkers to advisory, (b) pin model temperature/seed so the gate is reproducible, or (c) accept occasional gate flake and document it. Current framing is in [e2e/patterns-eval/AGENTS.md](../../e2e/patterns-eval/AGENTS.md) "Reading the invocation comparison". - -- **ailly-skill-eval paired-skills split** — The [skills/ailly-skill-eval/SKILL.md](../../skills/ailly-skill-eval/SKILL.md) is intentionally holistic. If its body grows a standalone "before you start, set up the project" section that would repeat on every use, split into a bootstrap skill and a per-call-site skill under `general:writing-paired-skills`. **Trigger:** the SKILL.md body acquires a setup procedure section. - -- **template variables in prefix/turn contents** — Today [DESIGN.md](../../DESIGN.md) templates only `path?` with matrix variables (the `PrefixBlock.path` and user-turn `TurnTemplate.path` lines); file *contents* are concatenated verbatim. A prompt authored with `{{var}}` placeholders — e.g. an externally-hosted system prompt carrying `{{currentDate}}` / `{{readOnlyInstructions}}` — cannot be filled by Ailly, so a harness must pre-render it outside the tool. Add a content-templating mechanism: fill `{{var}}` inside prefix-block and turn contents from a values source (an assembly-level `vars:` map, the per-binding matrix values, and/or `--var`), with an explicit choice on un-provided placeholders (leave verbatim vs error) and on delimiter collision with the existing `{{ matrix }}` path syntax. This lets an assembly reference a source prompt file directly and lets a variable like read-only mode become a clean matrix axis. **Motivating case:** the Scout Ailly prompt-eval framework (Scout repo `.ailly/developer/2026-06-08-A-prompt-eval/design.md`) first hit this — its Analyst prompt carried `{{currentDate}}`/`{{readOnlyInstructions}}` — but sidestepped it by dropping those (unused) variables and referencing the prompt directly with `kind: external`. The gap remains for any harness whose referenced prompt carries *meaningful* placeholders that must be filled at assemble time. **Trigger:** a harness needs Ailly to fill placeholders inside a referenced prompt file. - -- **whitespace-tolerant text assertions** — `text_contains` and `text_matches` ([DESIGN.md](../../DESIGN.md) text-assertion lines; [src/knowledge/assertions.rs](../../src/knowledge/assertions.rs)) match the raw response bytes, so a needle that spans a line wrap or differs only in run-length of spaces/newlines misses. Make both tolerant of insignificant whitespace: collapse runs of whitespace (spaces, tabs, newlines) to a single space in both the candidate text and the `value`/`pattern` before matching, so an expected phrase matches regardless of how the model — or a source prompt — wrapped it. Decide whether this is the default (changes existing semantics; needs a sweep of current e2e assertions) or an opt-in per-assertion flag alongside the existing `case_sensitive?` (e.g. `normalize_whitespace?: bool`), and how it interacts with a `text_matches` pattern that intentionally encodes `\s`/`\n`. **Motivating case:** the Scout prompt-eval suite must assert the Analyst decline phrase, which the source prompt hard-wraps as `I'm sorry, I can't help with\n that.`; without normalization the case needs a hand-written `\s+` pattern instead of the literal string. **Trigger:** an assertion needs to match text whose only difference from the expected value is whitespace/wrapping. - -- **eval `--over` outside the project root** — `ailly eval --over ` resolves the run directory through [`project_relative`](../../src/cli/mod.rs#L15), which returns an empty key when `` is not under the project's host root. The empty key makes [`VfsConversationRepository::list`](../../src/content/repository.rs#L128) read the project root instead of the run dir, so it matches 0 conversations and the eval silently scores nothing. The handler should resolve `--over` from the given path directly — e.g. root the conversations repository at `args.over`, or have `project_relative` preserve an absolute key and `dir_for`/`list` resolve it — rather than assuming `over` lives under the project. **Symptom:** three integration tests encode this shape (project at the real `e2e/`, `over` at a tempdir outside it) and are RED on `main_two`: [tests/eval_insurance_claim.rs](../../tests/eval_insurance_claim.rs), [tests/e2e_patterns_eval.rs](../../tests/e2e_patterns_eval.rs), [tests/e2e_delegate_52.rs](../../tests/e2e_delegate_52.rs), each asserting a non-zero `conversations_matched` against 0. **Trigger:** an operator (or a test) points `--over` at a run dir outside the project tree. - -## Deferred - -- **content/conversation deferred decisions** — Five revisit-after items carried over from the conversation design doc: typed `ImageSource`, narrowing `tool_result.content`, closing `TraceEvent` into a named enum, promoting `Conversation` to an aggregate root, and lifting blank/filled `Message` into type-states. See [TASK-NOTES-conversation-deferred.md](TASK-NOTES-conversation-deferred.md) for trigger conditions per item. -- **content/evaluation deferred decisions** — Three revisit-after items carried over from the evaluation design doc: `ToolCallSpec` extension, `f64` on `TextSemanticMatch.threshold` (and the resulting `PartialEq` rather than `Eq` derivations), and strict `ScriptBody` exclusivity. (The fourth original item, semantic validation on assertion shapes, was resolved by eval-assertions-core in favor of executor-level `Malformed` outcomes.) See [TASK-NOTES-evaluation-deferred.md](TASK-NOTES-evaluation-deferred.md) for trigger conditions per item. -- **knowledge/assertions deferred decisions** — Four revisit-after items carried over from the eval-assertions-core design doc: cache-hit token budgets, first-result vs all-results quantifier on `json_path`, reason-string format stability, and `tool_call_order` strict-contiguous variant. See [TASK-NOTES-assertions-deferred.md](TASK-NOTES-assertions-deferred.md) for trigger conditions per item. -- **knowledge/eval-script deferred decisions** — Eight revisit-after items carried over from the eval-script design doc: per-assertion `timeout_ms` override, suite-level `pass_env` defaults plus a denylist, hermetic `Program` resolution, runtime-version pinning via project config, stdout streaming into the report, an opt-in shared script library outside the project root, the Approach-2 `ScriptContext` bundle refactor, and full stderr surfacing. See [TASK-NOTES-eval-script-deferred.md](TASK-NOTES-eval-script-deferred.md) for trigger conditions per item. -- **engine deferred decisions** — revisit-after items across the engine-provider and engine-rig design docs: keyed `NoopEngine::from_table` constructor, `open_engine` bootstrap helper, `Conversation::request_at` on the aggregate, promoting `tokio` from dev-dep to runtime dep, live wire-up for OpenAI / Gemini / Bedrock, `Message.cache` forwarding into the Rig request, streaming, tool-definition wiring on requests, and the `RateLimited` quota vs request-rate distinction. See [TASK-NOTES-engine-deferred.md](TASK-NOTES-engine-deferred.md) for trigger conditions per item. -- **eval-cmd deferred decisions** — Five revisit-after items carried over from the eval-cmd design doc: per-class drill-down for `script` and `program`, report streaming, `--report-dir` override, exit code for deferred-only outcome, and `run_id` source. See [TASK-NOTES-eval-cmd-deferred.md](TASK-NOTES-eval-cmd-deferred.md) for trigger conditions per item. -- **project-layout deferred decisions** — Five revisit-after items carried over from the project-layout design doc: recursive `**` glob support, per-prompt cache strategy, `RemoteAssemblyRepository`, project schema validation at `Project::open`, and concurrent-writer atomicity on `MemoryFS`. See [TASK-NOTES-project-layout-deferred.md](TASK-NOTES-project-layout-deferred.md) for trigger conditions per item. -- **external-prefix-block deferred decisions** — Two revisit-after items from the `kind: external` prefix-block design (now landed; the third, configured source roots / Option B, is the standalone Follow-up above). (1) **Glob-over-external** — a glob-capable external block (the `System`/`Examples` shape) rather than the current single-file mirror of `File`. **Trigger:** a harness needs to pull many files from one external root. (2) **Policy to disable external blocks** — a project- or CLI-level switch that rejects `external` blocks outright. **Trigger:** CI or a published harness must guarantee a self-contained folder and forbid the `..`-escape. diff --git a/e2e/insurance-claim/README.md b/e2e/insurance-claim/README.md index 2b3a595..3c48611 100644 --- a/e2e/insurance-claim/README.md +++ b/e2e/insurance-claim/README.md @@ -183,7 +183,7 @@ A contributor may drop a `e2e/insurance-claim/.env` with `ANTHROPIC_API_KEY` ins The project demonstrates the assemble -> run -> eval pipeline end to end, with two intentionally deferred capabilities that affect what the regression suite can prove today.

Extend ci.sh with a noop structural gate that copies the fixtures into an in-tree run dir, runs ailly run as a verified no-op (idempotent), evals the regression suite, and python3-asserts the tool-call classes (must_call_tool, must_not_call_tool, tool_call_order) pass with zero failures.

The wiring that makes them live is what is absent. The model is never told which tools it may call, and `Conversation::run` never acts on a `tool_use` block. + +This project closes that gap end to end: an assembly can declare tools, `ailly run` can drive a multi-turn tool loop, and `ailly eval` can score the resulting tool calls. The pieces deliver value only together. A harness with no tool is inert; a tool with no harness cannot be reached; and neither is verifiable without the e2e fixtures that exercise the whole loop. That mutual dependency is what makes this a project rather than three unrelated features. + +The project is bounded to the **minimal vertical slice** that proves one real tool through the whole `assemble → run → eval → report` loop: the harness, the two web tools, and the e2e/testing that exercises them. File, Script, Clarify, and Subagent tools are a named follow-on project (§6). + +## 2. Prior Art + +- **Anthropic agentic loop.** The canonical request → `stop_reason: tool_use` → execute → `tool_result` → repeat shape, where `tools` is a *per-request* parameter (research.md [1][2]). Ailly mirrors this with `model.completion()` kept unary. +- **Rig's tool API.** `AgentBuilder.multi_turn` internalises the loop; rejected as the loop owner because it hides intermediate turns and breaks Ailly's inline-trace and mid-run-save guarantees (research.md [3]; §5). +- **Scripted tool-result fakes.** Anthropic test helpers, LangChain `FakeTool`, and AutoGen `FunctionTool` share one shape: a map from tool name to deterministic replies consumed in call order. This is the model for `NoopToolExecutor`. +- **`domain-driven-design/research/e2e`.** The structural model for `e2e/research/` (research.md [4]): `assemblies/`, `evals/`, `prompts/`, `context/`, `ci.sh`. +- **Ailly's own `content` / `knowledge` split.** Assertion *shapes* live in `content/evaluation.rs`; assertion *execution* lives in `knowledge/`. This project follows the same seam: `ToolDefinition` (a schema value) in `content/`, `ToolExecutor` and the tools (behavior) in `knowledge/tools/`. + +## 3. User Journey and Metrics + +The end-to-end journey, across all three features, in the user's language: + +> A competent Ailly user, fluent in `assemble → run → eval → report` but new to tools, declares a `tools` prefix block in an assembly, runs a multi-turn tool conversation, writes assertions over the tool calls, and reads the pass/fail in the report. The `web_search → web_fetch` research e2e runs green from a single `ci.sh`. + +The **measure of done is the Closing Bell** ([closing-bell.md](closing-bell.md)), a summative usability study run once near completion. It is not a continuously-running gate; it fixes the definition of done up front. Each in-scope feature also carries its own executable feature test (defined in that feature's own design), which is the continuous regression guard at feature altitude. + +## 4. Specification + +### Step 0: Shared contract (settle before parallel work) + +The harness feature delivers the contract every later feature depends on. Parallel tool features that agree on it integrate; those that do not collide. + +``` +ToolDefinition → src/content/ { name, description, input_schema: Value } + serializes into meta.tools; a schema value, + not behavior. + +meta.tools → conversation new optional field on the conversation meta + : Vec header (DESIGN.md schema change). Default + empty; skip-serialized when empty so existing + tool-free conversations are byte-identical. + +ToolExecutor → src/knowledge/ async dispatch: a tool call → a tool result. +NoopToolExecutor → tools/ scripted replies in call order, for tests and + the structural CI gate. + +Run-loop tool-turn → Conversation::run after a blank assistant slot is filled, if its +protocol content carries tool_use blocks: execute each + via the executor, append one Role::Tool message + with the tool_result block(s), append a fresh + blank assistant slot, and continue the loop. +``` + +The data flow that makes replay work: `assemble` resolves `PrefixBlock::Tools` (JSON files) into structured `ToolDefinition`s and writes them onto `meta.tools`. This is the one prefix-block kind that stops being concatenated system text. `run` reads `meta.tools` straight off the conversation file and forwards it on every `CompletionRequest`. Because the definitions live in the run artifact, a conversation replays without re-opening its assembly, preserving the conversation-as-artifact guarantee. + +### Features + +| # | Feature | Relationship | Delivers | +|---|---|---|---| +| 1 | **Harness** | sequential, first | The Step-0 contract: `ToolDefinition`, `meta.tools`, `CompletionRequest.tools`, `rig_engine` forwarding, `ToolExecutor` + `NoopToolExecutor`, the `Conversation::run` tool loop. | +| 2 | **Web tools** | parallel | `web_search`, `web_fetch` in `knowledge/tools/web.rs`, each with its own unit test exercising the tool logic directly. Depends on: Harness (Step-0 contract). | +| 3 | **e2e + testing** | sequential, last | `e2e/research/` (assembly declaring `web_search` + `web_fetch`, a research prompt, evals asserting the tool calls + order, noop-run `ci.sh`); the `insurance-claim` multi-turn structural gate. Depends on: Harness, Web tools. | + +Each feature is its own design → plan → build → cleanup cycle. Fine-grained interface decisions deliberately deferred to the owning feature's design, not settled here: whether `Conversation::run` takes `executor: Option<&dyn ToolExecutor>` or always-required with an empty default (research.md open #2), and whether the insurance-claim noop fixture is a standalone YAML file or generated by `ci.sh` (research.md open #3). + +### DESIGN.md change + +The conversation `meta` schema gains `tools?: ToolDefinition[]`, and the prose that says every prefix block is "ordered text concatenated into the window" is amended: `kind: tools` resolves to structured `ToolDefinition`s carried on `meta.tools`, not text. The agentic-loop shape (assistant `tool_use` → `Role::Tool` `tool_result` → next turn) is documented alongside the existing "blank assistant slot" description. + +### Release Flag + +The methodology defaults to one project-level release flag, whose job is to decouple deploy from release for a user-facing surface. This project has no such surface to gate, so it ships without a flag. Ailly is a library and CLI, and tool support has no always-on exposure. Tools are inert until an assembly *declares* a `tools` block **and** `run` is handed an executor. An assembly that names an unregistered tool fails loud rather than doing nothing silently. Each tool therefore stays dark until its feature registers it, and the mainline stays releasable at every step without a runtime flag. + +This is a deliberate departure from the default. It is justified by the absence of a release surface, not by a claim that the per-assembly opt-in substitutes for one. Revisit only if a tool ever becomes active without an explicit per-assembly declaration. + +## 5. Alternatives + +| Approach | Tool defs flow | Loop owner | Inline-trace + mid-run save | Replay from file alone | Verdict | +|---|---|---|---|---|---| +| **A: `meta.tools` + injected `ToolExecutor` + unary loop** | `assemble` → `meta.tools`; `run` forwards per request | `Conversation::run`, `model.completion()` stays unary | preserved | preserved | **chosen** | +| B: Rig `AgentBuilder.multi_turn` | Rig-internal registry | Rig | **broken** (intermediate turns hidden) | n/a | rejected | +| C: tools-as-text; `run` re-reads the assembly | stay as `Role::System` text | `Conversation::run` | preserved | **broken** (`run` needs the assembly) | rejected | + +**Build vs off-the-shelf.** No off-the-shelf agent loop preserves all three Ailly guarantees at once: inline per-turn trace, deterministic noop scripting, and conversation-as-artifact replay. Rig (already a dependency) is kept for the single completion call but not for the loop. (research.md *Falsification*.) + +## 6. Summary + +**Follow-on project, additional tools.** File (`File:Read`/`Edit`/`Glob`), Script (`Script:Bash`/`Node`/`Python`), `General:Clarify`, `Subagent`, and the `Todo:*` group are deferred to a named follow-on project.

They reuse this project's Step-0 contract unchanged. + +This narrows the scope listed in research.md, whose *Scope / In* section placed those tool groups in this project. That listing is superseded here; research.md is itself internally inconsistent on the point (its *What is deferred* note already treats them as later work). + +**Other deferred decisions** (research.md *What is deferred*): streaming tool responses; tool-call error recovery / `is_error: true` retry loop; per-turn tool variation (tools stay static per conversation in v1); `Message.cache` forwarding on tool turns; `NoopEngine::from_table` keyed-by-binding; Rig `AgentBuilder` / `multi_turn`. + +**Open within this project, settled in feature designs:** `ToolExecutor` `Option`-vs-required signature; the insurance-claim noop-fixture shape.

It is the foundation every later feature consumes; a harness with no tool is inert but releasable (tools stay dark until an assembly declares one and `run` is handed an executor — project design §4 *Release Flag*). + +## Prior Art (in-repo patterns this feature mirrors) + +- **`NoopEngine` script-queue** (`engine.rs:179-267`): a `Mutex>` consumed in call order regardless of input, with `from_scripts` / `from_replies` constructors and an `auto()` empty-but-never-exhausted mode. `NoopToolExecutor` mirrors this exactly — a per-tool-name queue of scripted `tool_result` strings, popped in call order, with an empty `default()` that serves a no-tools conversation (parallels `NoopEngine::auto()` returned by `open_engine_for_model("noop")`). +- **The existing eval read-path** (`assertions.rs`): `extract_tool_uses` (`:993`) walks `Content::Blocks`, keeping only `ToolUse` blocks in (message order, block order); `tool_use_name` (`:1010`) projects the `name`. The run loop's tool-turn detection walks the just-filled slot the same way — `Content::Blocks` filtered to `ToolUse`. The producer this feature adds feeds the consumer that already exists; the implementer wires into existing machinery rather than rebuilding it. +- **`yaml_to_json` bridge** (`assertions.rs:1148`): round-trips `serde_yaml_ng::Value → serde_json::Value` through a JSON string. Rig's `ToolDefinition.parameters` is `serde_json::Value` (rig-core 0.37 `completion/request.rs:191-198`), Ailly's `input_schema` is `serde_yaml_ng::Value`; the rig-forwarding lowering reuses this exact 4-line seam, so the lowering is not its own red-green cycle. +- **The `content` / `knowledge` seam**: assertion *shapes* live in `content/evaluation.rs`; assertion *execution* lives in `knowledge/assertions.rs`. `ToolDefinition` is a schema value (serialized into `meta.tools`), so it follows the *shape* side into `content/`; `ToolExecutor` is behavior, so it follows the *execution* side into `knowledge/tools/`.

It is serialized into `Meta.tools` (a `content` type), forwarded by reference on `CompletionRequest` (an `engine` type), and parsed from `PrefixBlock::Tools` JSON files (a `content/assembly` concern). Every consumer is at or below the `content`/`engine` layer; none is in `knowledge`. The codebase's layering rule is explicit in `knowledge/mod.rs` ("Parallel to `content` (domain values) and `engine` (LLM I/O)") — `content` and `engine` must not depend up into `knowledge`. Placing `ToolDefinition` in `knowledge/` would force `Meta` (`content`) and `CompletionRequest` (`engine`) to depend on `knowledge`, inverting the layering. The established precedent settles it: assertion *shapes* live in `content/evaluation.rs` while their checkers live in `knowledge/assertions.rs`; `ToolDefinition` is the schema half of the same kind of split (the executor is the behavior half, and it does go in `knowledge/tools/`). + +**Decision:** `ToolDefinition` lands in `src/content/conversation.rs`, next to `Meta`, `ContentBlock`, and `ToolUseId` that reference and surround it — not a new `content/tools.rs`. It is small and tightly coupled to `Meta.tools`; a standalone file earns its keep only when the type grows behavior, which `ToolDefinition` (a pure value) does not. `content/mod.rs` already re-exports through `pub mod conversation;`, so no new export plumbing is needed. + +```rust +/// A tool the model may call, declared by an assembly's `kind: tools` prefix +/// block and carried on `meta.tools`.

The two literal constructions update: the real one at `conversation.rs:449` passes `tools: &self.meta.tools`; the test helper `request()` at `engine.rs:284` and the eval-path construction at `assertions.rs:367` pass `tools: &[]`. + +`rig_engine.rs:62` replaces `tools: Vec::new()` with the lowered Ailly tools: + +```rust +tools: request + .tools + .iter() + .map(|t| rig::completion::ToolDefinition { + name: t.name.clone(), + description: t.description.clone(), + parameters: yaml_value_to_json(&t.input_schema), + }) + .collect(), +``` + +`yaml_value_to_json` is the same `serde_yaml_ng::Value → serde_json::Value` round-trip already implemented as `yaml_to_json` in `assertions.rs:1148`. Rather than make that private fn `pub(crate)` across modules, the rig adapter gets its own one-line copy (the conversion is 4 lines and already duplicated nowhere else; a shared helper is a refactor-phase candidate, not a feature requirement). Existing rig translation tests stay green because an empty `tools` slice lowers to an empty `Vec`. + +### `ToolExecutor` trait + `NoopToolExecutor` — `src/knowledge/tools/` + +New module `src/knowledge/tools/mod.rs`, registered with `pub mod tools;` in `knowledge/mod.rs`. + +```rust +#[async_trait::async_trait] +pub trait ToolExecutor: Send + Sync { + /// Execute one tool call and produce its result. `call` is a + /// `ContentBlock::ToolUse`; the return is a `ContentBlock::ToolResult` + /// whose `tool_use_id` echoes the call's `id`. + /// + /// # Errors + /// Returns [`ToolError`] when no result can be produced for `call` + /// (e.g. a noop script exhausted for the named tool). + async fn execute(&self, call: &ContentBlock) -> Result; +} +``` + +**Argument/return projection (resolves the Step-0 "Feature 1 design detail"):** `execute` takes the whole `ContentBlock` (the `ToolUse` variant), not a destructured `{id, name, input}` tuple. Reason: the loop already holds `&ContentBlock` from walking `Content::Blocks` (mirroring `extract_tool_uses`), and the executor must echo `id` into the result's `tool_use_id` — passing the block keeps `id`/`name`/`input` together and matches the trait's "one block in, one block out" framing in the project plan. The executor destructures internally: + +```rust +let ContentBlock::ToolUse { id, name, input } = call else { + return Err(ToolError::NotAToolUse); +}; +``` + +and returns `ContentBlock::ToolResult { tool_use_id: id.clone(), content: .into(), is_error: None }`. Returning a `Result` (not a bare `ContentBlock`) lets `NoopToolExecutor` signal script exhaustion the way `NoopEngine` signals `NoopExhausted`; the run loop maps `ToolError` into a `RunError` variant. + +```rust +#[derive(Debug, thiserror::Error)] +pub enum ToolError { + #[error("no scripted tool result for tool `{name}` (call #{call_index})")] + NoopExhausted { name: String, call_index: usize }, + #[error("executor received a non-tool_use block")] + NotAToolUse, +} +``` + +`NoopToolExecutor` — scripted `tool_result` strings keyed by tool name, consumed in call order per name (mirrors `NoopEngine`'s `VecDeque` queue): + +```rust +pub struct NoopToolExecutor { + /// tool name -> queued result strings, popped front-to-back per call. + scripts: Mutex>>, +} + +impl NoopToolExecutor { + /// Empty executor: any tool call errors with `NoopExhausted`.

An `Option<&dyn ToolExecutor>` would reintroduce exactly the branching the engine side designed away. +- **Ergonomic for `cli/run.rs`.** The call site at `:81` already does `let engine = open_engine_for_model(...)?; ... conv.run(engine.as_ref())`. It gains one line — `let executor = NoopToolExecutor::default();` — and calls `conv.run(engine.as_ref(), &executor)`. No factory, no `None`, no per-conversation conditional. (The plan's surfaced assumption — "no noop executor factory analogous to `NoopEngine::auto()`" — is resolved by `Default`: the default *is* the factory.) +- **Ergonomic for the noop e2e gates.** Those gates run `ailly run` against a noop model; a no-tools conversation gets the default executor for free, and a tool-bearing fixture supplies a scripted `NoopToolExecutor::from_scripts(...)`. Neither path threads an `Option`. +- **No silent-skip footgun.** With `Option::None`, a `tool_use` block in a conversation handed no executor would need a runtime error path anyway (the project plan's "error if a tool_use appears with no executor"). The required-executor design makes that error structurally impossible at the type level: there is always an executor, and an empty one produces a loud `NoopExhausted` rather than a silently-dropped tool turn. + +New signature: + +```rust +pub async fn run( + &mut self, + engine: &dyn crate::engine::engine::EngineProvider, + executor: &dyn crate::knowledge::tools::ToolExecutor, +) -> Result<(), RunError> { /* loop below */ } +``` + +`RunError` (`conversation.rs:340`) gains one variant: + +```rust +#[error("tool execution failed: {0}")] +Tool(#[from] crate::knowledge::tools::ToolError), +``` + +### Run-loop tool-turn protocol + +The loop body at `conversation.rs:448` keeps its existing "fill the next blank assistant slot" core and adds a tool turn after each fill: + +1. Find the next blank assistant slot (`next_blank_assistant`, unchanged). +2. Build the `CompletionRequest` with `messages: self.messages_up_to(index)`, `tools: &self.meta.tools`, fill the slot (`fill_blank_assistant`, unchanged). +3. Inspect the *just-filled* slot's body. If it is `Content::Blocks` containing one or more `ContentBlock::ToolUse` (walk it the way `extract_tool_uses` does — by block kind, in block order): + - For each `ToolUse` block in order, call `executor.execute(block).await?`, collecting the returned `ToolResult` blocks. + - Append one `Message { role: Role::Tool, body: Some(Content::Blocks(results)), cache: false, trace: None, _phase: PhantomData }` after the filled slot. + - Append a fresh blank assistant slot (`Message { role: Role::Assistant, body: None, .. }`) after the tool message. + - Continue the loop; the next iteration fills that new blank slot. +4. If the filled slot carries no `ToolUse` blocks (plain `Content::Text`, or `Content::Blocks` with only `Text`/`Thinking`), the loop terminates exactly as it does today (no new blank slot is appended). + +This preserves the inline-trace and mid-run-save guarantees: each assistant turn is filled and its trace populated before the next request, and the appended `Role::Tool` message + blank slot are part of the conversation aggregate that `cli/run.rs:96` saves. It mirrors the Anthropic agentic loop (`tool_use` → `tool_result` → next turn) with `model.completion()` kept unary (project design §2, Approach A). + +### Assembly-resolver change (`PrefixBlock::Tools` stops being text) + +Today `resolve_prefix_block` (`assembly.rs:243`) returns a `String` and the `System | Tools | Examples` arm (`:254`) globs+concats JSON files into system text, which `render` (`:212`) pushes as a `Role::System` message. For `Tools` only, that becomes structured definitions on `meta.tools`: + +- `Assembly::render` splits prefix-block handling. Non-`Tools` blocks keep producing a `Role::System` text message (unchanged path). A `PrefixBlock::Tools` block instead resolves each globbed JSON file into a `ToolDefinition` (via `serde_yaml_ng::from_str` / `serde_json::from_str` over the file body — JSON is a YAML subset, so the existing `serde_yaml_ng` parser reads these `.json` files; this matches how the codebase already treats `input_schema` as a `serde_yaml_ng::Value`) and pushes the parsed defs onto the `tools` vec that seeds `Meta.tools`. The `Tools` arm is removed from the text-concatenation match arm at `:254` and handled separately in `render`. +- The render loop therefore accumulates a `Vec` alongside the session; `Meta { .. tools }` is constructed with it. A `Tools` block produces **no** `Role::System` message — it is the one prefix-block kind that stops being concatenated text (project design §4). +- A new `RenderError` path covers a `tools` JSON file that does not parse into a `ToolDefinition` (malformed schema file), so a bad tool fixture fails loud at assemble time rather than silently dropping the tool. Assembly round-trip tests that exercised `kind: tools` as text update to the new render output (no system message; defs on `meta.tools`). + +### Rig forwarding (summary) + +`rig_engine.rs:62`: `tools: Vec::new()` → lower `request.tools` into `rig::completion::ToolDefinition { name, description, parameters }`, converting `input_schema: serde_yaml_ng::Value` to `parameters: serde_json::Value` via the yaml→json round-trip. Empty input ⇒ empty output ⇒ existing rig tests unchanged. This is the only line that wires Ailly tools onto a live request; until an assembly declares a `tools` block, every request still forwards an empty slice (releasable-at-every-step). + +### CLI `run` wiring (`cli/run.rs`) + +`fill_and_save` (`:86`) and its caller (`:81`) thread an executor. The simplest placement: construct `let executor = NoopToolExecutor::default();` in `run` (`:72`) once, pass `&executor` through `fill_and_save` into `conv.run(engine, &executor)`. `tools` flow automatically because `run` reads `&self.meta.tools` off the loaded conversation — `cli/run.rs` does not pass tools explicitly. (For v1 the CLI executor is always the empty noop; a real executor registry is a follow-on concern — project design §6. The empty default is correct today because no in-tree tool exists until Feature 2, and the e2e gates script their own `NoopToolExecutor`.) + +### DESIGN.md change (ships with this feature) + +Per the documentation-sync rule, the schema doc moves in lockstep with the code: +- `conversation.meta` (`DESIGN.md:12-16`) gains `tools?: ToolDefinition[]`, with a `ToolDefinition` shape (`name` / `description` / `input_schema`) documented. +- The assembly prose "the engine treats every block as ordered text concatenated into the window" (`DESIGN.md:64`) is amended: `kind: tools` resolves to structured `ToolDefinition`s carried on `meta.tools`, not text — the one prefix-block kind that stops being concatenated system text. +- The agentic-loop shape (assistant `tool_use` → `Role::Tool` `tool_result` → next blank assistant turn) is documented alongside the existing "blank assistant slot" prose (`DESIGN.md:37`). + +## Split-vs-whole decision: keep Feature 1 whole (7 steps) + +The project plan's *At-ceiling flag* warned Feature 1 sits at the 7-step max and flagged two bundles (step 3: borrowed field + rig lowering; step 4: `ToolExecutor` + `NoopToolExecutor`) that, if either needs its own step, tip the build over 7 and force a schema/execution split. Verifying both bundles against the actual code, neither needs splitting: + +- **Step 3's rig lowering reuses an existing, proven 4-line seam** (`yaml_to_json`, `assertions.rs:1148`). The lowering is a `map`-and-`collect` over a borrowed slice; an empty slice keeps existing rig tests green. It does not warrant its own red-green cycle — adding the field and forwarding it land in one cycle. +- **Step 4's `NoopToolExecutor` mirrors `NoopEngine`'s queue directly** — a `Mutex>>` popped per name in call order, the same machinery as `NoopEngine`'s `Mutex>`. The trait is one async method. Trait + noop impl land together because the noop is the trait's first and only consumer in this feature. + +Therefore **keep Feature 1 as one 7-step feature**, exactly the project plan's sketch: +1. `ToolDefinition` value type (round-trips a `*.json` fixture). +2. `Meta.tools` skip-when-empty field (byte-identical round-trip + default-skip invariants hold). +3. `CompletionRequest.tools` borrowed field + rig forwarding (existing rig tests green). +4. `ToolExecutor` + `NoopToolExecutor` in `knowledge/tools/` (scripted results in call order). +5. Assembly resolves `Tools` to structured defs on `meta.tools` (assembly round-trip tests updated). +6. `Conversation::run` tool loop (feature-test session-shape assertion passes). +7. CLI `run` wiring (empty `NoopToolExecutor` default; `ailly run` drives the loop end to end). + +Each step is a clean single red-green-refactor cycle leaving `check` + tests green. A schema/execution split (schema half: steps 1, 2, 5; execution half: steps 3, 4, 6, 7) is the pre-identified fallback if any step is found at build time to need its own cycle — but the analysis above shows it does not, so the whole-feature form is chosen. + +## Alternatives + +The loop-owner and tool-flow alternatives are settled at project altitude (design §5 — **Approach A** chosen over Rig `AgentBuilder.multi_turn`, which hides intermediate turns and breaks inline-trace/mid-run-save, and over tools-as-text, which breaks replay-from-file). This feature does not re-litigate them. The two feature-local alternatives are the open decisions, resolved above: +- **Open #1**: `ToolDefinition` in `knowledge/` (rejected — inverts the content/engine→knowledge layering) vs `content/` (chosen — schema value, matches the evaluation-shape precedent). +- **Open #2**: `Option<&dyn ToolExecutor>` (rejected — reintroduces the branching `NoopEngine::auto()` designed away, and still needs a runtime error for an executor-less `tool_use`) vs always-required with an empty `NoopToolExecutor` default (chosen — mirrors `NoopEngine::auto()`, ergonomic for both the CLI and the noop e2e gates, makes the silent-skip footgun structurally impossible). + +A minor sub-decision settled here: `ToolDefinition` in `content/conversation.rs` (next to `Meta`) rather than a new `content/tools.rs` — it is a small pure value tightly coupled to `Meta.tools`; a standalone module is unearned until the type grows behavior. + +## Summary + +- **Open #1 — resolved: `ToolDefinition` in `src/content/conversation.rs`.** It is a serde schema value serialized into `Meta.tools` and forwarded on `CompletionRequest`; both consumers sit at/below the `content`/`engine` layer, and `content`/`engine` must not depend up into `knowledge`. Matches the precedent where assertion *shapes* live in `content/` and their *execution* lives in `knowledge/`. +- **Open #2 — resolved: `Conversation::run(&mut self, engine, executor: &dyn ToolExecutor)`, always required, empty `NoopToolExecutor::default()` for no-tools.** Mirrors the `NoopEngine::auto()` empty-default precedent, keeps the loop branch-free, is one extra line at `cli/run.rs`, and makes an executor-less `tool_use` impossible by construction. +- **Split decision — keep Feature 1 whole at 7 steps.** Both at-ceiling bundles (step 3 rig lowering, step 4 noop executor) reuse proven in-repo seams (`yaml_to_json`; the `NoopEngine` queue) and each fits a single red-green cycle; the schema/execution split is the held-in-reserve fallback, not needed. + diff --git a/.ailly/developer/2026-06-14-A-tool-calls/feature-1-harness/feature-test.md b/.ailly/developer/2026-06-14-A-tool-calls/feature-1-harness/feature-test.md new file mode 100644 index 0000000..af527c4 --- /dev/null +++ b/.ailly/developer/2026-06-14-A-tool-calls/feature-1-harness/feature-test.md @@ -0,0 +1,74 @@ +# Feature 1 Feature Test: Tool-call harness loop + +**Project:** [../design.md](../design.md) | **Feature design:** [design.md](design.md) | **Plan:** [../plan.md](../plan.md) +**Type:** Feature (Feature 1 of 3) | **Status:** Red (failing as intended; type-first stubs keep `check` green) + +## User Story + +**Given** a conversation whose blank assistant slot is about to be filled, and +a model (noop-scripted) whose first reply is an assistant `tool_use` block and +whose second reply is assistant text, and a tool executor (noop-scripted) that +returns the matching `tool_result`, +**When** the operator drives `Conversation::run` with both the engine and the +executor, +**Then** the resulting session has the agentic shape +`user → assistant(tool_use) → tool(tool_result) → assistant(text)` — the +assistant's `tool_use` was dispatched through the executor, its `tool_result` +was appended as a `Role::Tool` message, and a fresh blank assistant slot was +filled with the model's follow-up text. + +## Test + +- **File:** `tests/tool_loop.rs` — `run_drives_tool_use_then_tool_result_then_text`. +- Drives `Conversation::run(&engine, &executor)` directly so both sides are + deterministic and hermetic: `NoopEngine::from_scripts` scripts the + `tool_use`-then-text replies; `NoopToolExecutor::from_scripts` scripts the + `tool_result` for the named tool.

A one-line setup edit to keep a struct literal compiling is a mechanical co-change, not a relitigation of the frozen contract; it is the same class of co-change the test author already applied to `engine_provider.rs` in the feature-test commit (updating its `run(&engine)` call to `run(&engine, &executor)`). + +**All 14 sites Step 2 must touch:** `assembly.rs:232` (real render path — see Step 5 for the *resolved-vec* variant), `conversation.rs:548` (inline `meta()` helper), `project.rs:781`, `repository.rs:797`, `cli/run.rs:199` & `:355`, `knowledge/assertions.rs:395` & `:1349`, `knowledge/eval.rs:704`, `tests/eval_script.rs:167`, `tests/eval_program_outputs.rs:219`, `tests/eval_assertions.rs:186`, `tests/eval_judge.rs:169`, and `tests/tool_loop.rs:65`. + +--- + +## Step 1: `ToolDefinition` value type + +**Enables:** the type that every later step references — `Meta.tools: Vec` (Step 2), `CompletionRequest.tools: &[ToolDefinition]` (Step 3), the assembly resolver's parse target (Step 5). The feature test does not name `ToolDefinition` directly, so no `tool_loop.rs` assertion flips here; this is the domain-value foundation (Step-0 contract item). + +Introduce `ToolDefinition` in `src/content/conversation.rs`, next to `Meta` / `ContentBlock` / `ToolUseId` (open #1 resolved → `content/`, per feature design §"Open #1"). Pure value, no behavior: + +```rust +/// A tool the model may call, declared by an assembly's `kind: tools` prefix +/// block and carried on `meta.tools`.

The doc-comment in `knowledge/tools/mod.rs:4` that already links `[crate::content::conversation::ToolDefinition]` resolves once the type exists. + +**RED test (this step's own unit test):** a round-trip over the real `lookup_policy.json` byte shape — `serde_yaml_ng::from_str::(…)` parses `{ name, description, input_schema }`, and the parsed `name` / `description` / a nested `input_schema` key assert exactly. (JSON is a YAML subset, so the project's `serde_yaml_ng` parser reads the `.json` file body unchanged — the same treatment `ContentBlock::ToolUse.input` already gets.) `check` + tests stay green; the feature test stays red. + +## Step 2: `Meta.tools` skip-when-empty field + +**Enables:** `meta.tools` becomes a carrier — Step 3 lends `&self.meta.tools` on the request, Step 5 writes resolved defs onto it. No `tool_loop.rs` assertion flips, but the test's setup literal now compiles against the new field (see "frozen-feature-test" section above). + +Add to `Meta` (`conversation.rs:53`), after `binding`: + +```rust +#[serde(default, skip_serializing_if = "Vec::is_empty")] +pub tools: Vec, +``` + +Then add `tools: Vec::new()` to **all 14** `Meta {…}` literals enumerated above (the `assembly.rs:232` site takes `Vec::new()` here; Step 5 swaps it for the resolved vec). + +**Invariants that must still pass (no new test needed — these already exist):** `round_trip_preserves_three_message_fixture` (`conversation.rs:729`) and `meta_defaults_are_skipped_on_emit` (`:737`), over `THREE_MESSAGE_FIXTURE` (`:465`) which omits `tools:`. Because the field is `default` + `skip_serializing_if = "Vec::is_empty"`, an empty `tools` deserializes from the tools-free fixture and never re-emits — both invariants hold unedited, so existing tool-free conversation files stay byte-identical. `check` + tests green; feature test still red. + +## Step 3: `CompletionRequest.tools` borrowed field + rig forwarding + +**Enables:** the model is *told* its tools. No `tool_loop.rs` assertion flips (the noop engine ignores the request's tools — it serves its script regardless of input), but this lands the Step-0 request-side contract and keeps the rig path honest. It is a prerequisite for the loop being correct end-to-end through a live engine. + +`CompletionRequest<'a>` (`engine.rs:24`) gains a borrowed slice mirroring `messages`: + +```rust +pub struct CompletionRequest<'a> { + pub model: ModelId, + pub messages: &'a [Message], + pub tools: &'a [ToolDefinition], + pub debug: bool, +} +``` + +Update the **two** `CompletionRequest {…}` constructions: the real one in `Conversation::run` (`conversation.rs:465`) passes `tools: &self.meta.tools`; the `request()` test helper (`engine.rs:284`) passes `tools: &[]`. (`assertions.rs` constructs no `CompletionRequest`; it only reads `tool_use` blocks — no change there.) + +`rig_engine.rs:62` replaces `tools: Vec::new()` with the lowered Ailly tools: + +```rust +tools: request + .tools + .iter() + .map(|t| rig::completion::ToolDefinition { + name: t.name.clone(), + description: t.description.clone(), + parameters: yaml_value_to_json(&t.input_schema), + }) + .collect(), +``` + +`yaml_value_to_json` is a 4-line local copy of the proven `yaml_to_json` round-trip (`assertions.rs:1148`) — a private fn in `rig_engine.rs` rather than crossing a module boundary to make the existing one `pub(crate)` (a shared helper is a refactor-phase candidate, not a feature requirement). Existing `messages_to_rig` translation tests (`rig_engine.rs:679+`) test message translation, not request assembly, so they are untouched; with an empty `tools` slice the lowering yields an empty `Vec`, so any rig-request-level coverage stays green. + +**RED test (this step's own unit test):** assert the lowering — given a `CompletionRequest` carrying one `ToolDefinition`, the rig `tools` vec has length 1 with the matching `name` and a `parameters` JSON object equal to the yaml→json of `input_schema`; given an empty slice, the rig `tools` vec is empty. `check` + tests green; feature test still red. + +## Step 4: `NoopToolExecutor::execute` body + +**Enables:** `assert_tool_result(&conversation.session[2], CALL_ID)` (`tool_loop.rs:131`) — the executor can finally produce a `tool_result` echoing the call id. (The assertion only fires once Step 6 appends the tool turn; this step makes the *production* real so Step 6 has something to append.) Replaces the single executable `todo!()` in `src/` (`tools/mod.rs:96`). + +Implement `execute`: + +```rust +async fn execute(&self, call: &ContentBlock) -> Result { + let ContentBlock::ToolUse { id, name, input: _ } = call else { + return Err(ToolError::NotAToolUse); + }; + let mut scripts = self.scripts.lock().expect("NoopToolExecutor mutex poisoned"); + let queue = scripts.get_mut(name); + let reply = queue.and_then(VecDeque::pop_front).ok_or_else(|| { + ToolError::NoopExhausted { name: name.clone(), call_index: /* per-name index */ } + })?; + Ok(ContentBlock::ToolResult { + tool_use_id: id.clone(), + content: Content::from(reply), + is_error: None, + }) +} +``` + +Mirrors `NoopEngine`'s `Mutex` pop-in-call-order pattern (the `scripts` field already holds `Mutex>>` and its `#[expect(dead_code, …)]` is removed once the body reads it). The `call_index` for `NoopExhausted` is the per-name call ordinal (track via a sibling `Mutex>` counter, or report the post-pop depth — implementer's choice; the feature test never exercises the exhausted path, so any honest value satisfies the contract). The `Content::from(String)` impl already exists (`conversation.rs:230`). + +**RED test (this step's own unit test):** `from_scripts([("lookup_policy", vec!["status: in_force"])])`, call `execute` with a `ToolUse { id: "toolu_001", name: "lookup_policy", … }`, assert the returned `ToolResult.tool_use_id == "toolu_001"`; a second call to the same tool with an empty queue returns `Err(ToolError::NoopExhausted { name: "lookup_policy", … })`; `execute` on a non-`ToolUse` block returns `Err(ToolError::NotAToolUse)`. `check` + tests green; feature test still red (the loop does not yet call `execute`). + +## Step 5: Assembly resolves `kind: tools` to structured defs on `meta.tools` + +**Enables:** an assembly that declares `{ kind: tools, … }` now lands `ToolDefinition`s on `meta.tools` instead of a `Role::System` text message — the end-to-end "declare a tool → meta.tools lists it" path (Closing Bell task 1). The feature test constructs its `Conversation` by hand and never calls `Assembly::render`, so no `tool_loop.rs` assertion flips here; this step is required for the **CLI/e2e** path to feed the loop (Features 2/3 depend on it) and is the schema half's last piece. + +In `Assembly::render` (`assembly.rs:212`), split prefix-block handling. Non-`Tools` blocks keep producing a `Role::System` text message (unchanged). A `PrefixBlock::Tools` block instead resolves each globbed JSON file into a `ToolDefinition` (parse the file body with `serde_yaml_ng::from_str` — JSON is a YAML subset, consistent with Step 1) and pushes the parsed defs onto a `Vec` that seeds `Meta.tools`. A `Tools` block produces **no** `Role::System` message — it is the one prefix-block kind that stops being concatenated system text. + +Mechanics: remove `PrefixBlock::Tools` from the `System | Tools | Examples` text-concat arm in `resolve_prefix_block` (`assembly.rs:255`) and handle it in `render` (reading each globbed file body and parsing). The `Meta {…}` at `assembly.rs:232` (set to `Vec::new()` in Step 2) takes the accumulated `tools` vec. Add a `RenderError` variant for a `tools` JSON file that does not parse into a `ToolDefinition`, so a malformed tool fixture fails loud at assemble time rather than silently dropping the tool. + +**Test surface:** any existing assembly test asserting a `kind: tools` block renders to a `Role::System` text message updates to the new output (no system message; defs on `meta.tools`). The `assemble_against_insurance_claim_is_byte_identical_across_runs` test (passes today, declares `kind: tools`) must stay green — its assertion is byte-identity across two assembles, which holds regardless of *where* tools land, but verify it still passes after the render change. + +**RED test (this step's own unit test):** seed a memory project with one `tools/*.json` (the `lookup_policy.json` shape), render an assembly whose prefix declares `{ kind: tools, path: tools/*.json }`, assert the resulting `conversation.meta.tools` has length 1 with `name == "lookup_policy"` **and** the session contains no `Role::System` message from that block. A malformed JSON file asserts the new `RenderError` variant. `check` + tests green; feature test still red. + +## Step 6: `Conversation::run` tool loop (flips the feature test green) + +**Enables:** the whole feature test — the role-shape assertion (`tool_loop.rs:121`, `[User, Assistant, Tool, Assistant]`), `assert_tool_use` (`:128`), `assert_tool_result` (`:131`), the final-assistant-text assertion (`:135-144`), and `next_blank_assistant().is_none()` (`:147`). + +Replace the type-first stub body of `Conversation::run` (`conversation.rs:454`, currently `let _ = executor;` + the plain fill loop). Keep the existing "fill the next blank assistant slot" core; after each fill, add the tool turn: + +1. Find the next blank assistant slot (`next_blank_assistant`, unchanged) and build the `CompletionRequest` with `tools: &self.meta.tools` (the field added in Step 3); fill the slot (`fill_blank_assistant`, unchanged). +2. Walk the *just-filled* slot's body. If it is `Content::Blocks` containing one or more `ContentBlock::ToolUse` (filter by block kind in block order, mirroring `extract_tool_uses` at `assertions.rs:993`): + - For each `ToolUse` block in order, call `executor.execute(block).await?` (the `?` maps `ToolError` into `RunError::Tool` via the existing `#[from]`), collecting the returned `ToolResult` blocks. + - Append one `Message { role: Role::Tool, body: Some(Content::Blocks(results)), cache: false, trace: None, _phase: PhantomData }` after the filled slot. + - Append a fresh blank assistant slot (`Message { role: Role::Assistant, body: None, … }`). + - Continue the loop; the next iteration fills that new blank slot from the engine's *next* scripted reply. +3. If the filled slot carries no `ToolUse` blocks (plain `Content::Text`, or `Blocks` with only `Text` / `Thinking`), the loop terminates exactly as today — no new blank slot is appended. + +Borrow note: `execute` borrows `&self.session[i]` (the filled slot) while the appends mutate `self.session`. Resolve by cloning the `ToolUse` blocks (or their owned fields) out of the filled slot before the append, so the executor calls and the `push`es do not overlap a borrow — `ContentBlock: Clone` is already derived. + +With the noop engine's two scripted replies (`tool_use` then text) and the noop executor's one scripted `status: in_force`, the loop produces `user → assistant(tool_use) → tool(tool_result) → assistant(text)` and terminates when the second (text) reply carries no `tool_use`. The frozen feature test goes green; `engine_provider.rs`'s no-tools `run` test stays green (its replies are plain text, so no tool turn is ever appended). `check` + full suite green except the three pre-existing e2e gates (Feature 3's scope, unchanged by this step). + +--- + +## Dependency flow (why this order) + +value type (1) → meta carrier (2) → request field + rig lowering (3) → executor body (4) → assembly resolver (5) → run loop (6). Each arrow is a hard compile/semantic dependency: Step 2 needs the type from 1; Step 3 lends `&self.meta.tools` introduced in 2; Step 6's loop calls the `execute` made real in 4 and reads tools placed by 3; Step 5 is the CLI/e2e feeder that 6's loop consumes through the loaded conversation (independent of the feature test, but required for Features 2/3 and sequenced before 6 so the schema half is complete before the execution half closes). The design's step 7 (CLI wiring) is dropped — already committed in the feature-test stub. + +## Step-count justification + +6 steps, within the 3–7 band. The design analyzed two at-ceiling bundles and kept them whole; this plan finds the path is actually *shorter* than the design's 7 because the CLI wiring is pre-committed. No bundle needs its own cycle: Step 3's rig lowering reuses the proven `yaml_to_json` seam (empty slice keeps rig tests green); Step 4 is a single method body over an already-built `Mutex>`; Step 5 is a single render-path split. The schema/execution split the design held in reserve is not invoked.

No executor actually *does* anything against the outside world. This feature delivers the first two real tools — `web_search` and `web_fetch` — each implementing the `ToolExecutor` contract, so a model can issue a search query or fetch a URL and receive a real `tool_result`. + +Two facts from the project plan bound the work to a deliberately thin slice: + +1. **The e2e never calls these tools live.** Feature 3's `e2e/research/` and the insurance-claim gate drive the loop through `NoopToolExecutor` with scripted replies (project plan §"Feature 3"; research.md "noop run — no live web API"). The real `web_search`/`web_fetch` code is therefore exercised **only** by their own mocked unit tests (project plan §"Feature 2": "each with its own unit test exercising the tool logic directly"). CI makes **zero** live network calls. +2. **No in-repo HTTP/search seam to copy.** Verified — `src/` has no `web*.rs`/`http*.rs` module (project plan §"Feature 2").

This feature builds the web seam by mirroring that precedent, not by inventing a new shape. + +The research "(tbd)" — *which* search provider backs `web_search` — is resolved here (Specification §"web_search provider, resolved"). + +The job, then, is: pick a mockable seam for each tool so the unit tests inject a fake and the production adapter stays a minimal-but-correct vertical slice; author the two `ToolDefinition` JSON fixtures Feature 3 declares; and keep the whole feature off the network at test time. + +## Prior Art (in-repo patterns this feature mirrors) + +- **`ScriptRunner` port + `TokioScriptRunner` adapter + hand-rolled `FakeScriptRunner`** (`src/knowledge/script_runner.rs:89`/`:117`, fake at `assertions.rs:2114`). The canonical in-repo "I/O behind a trait so the caller unit-tests against a fake" seam. `check_script` (`assertions.rs:497`) takes `runner: &dyn ScriptRunner` and is unit-tested with a `Mutex>` fake — never spawning a real process. The production adapter's own correctness is left to an integration test that touches the real resource (`tests/eval_script.rs` spawns real `python3`); the comment at `script_runner.rs:111-117` states the rule outright: *"a subprocess adapter has no seam below it to mock."* The web tools adopt this verbatim: a `SearchProvider`/`Fetcher` port, a `reqwest` production adapter, a hand-rolled fake in the unit test. +- **`EngineProvider` / `NoopEngine`** (`src/engine/engine.rs:179`). The original of the pattern `ScriptRunner` copies: a behavior trait with a real network adapter (`RigEngine`) and a deterministic scriptable adapter (`NoopEngine`, a `Mutex>`). `NoopToolExecutor` (Feature 1) already follows it on the executor axis. +- **`NoopToolExecutor`'s `ToolUse` destructure + `ToolResult` build** (`src/knowledge/tools/mod.rs:93-117`). Each web tool's `execute` reuses this exact shape: `let ContentBlock::ToolUse { id, name, input } = call else { return Err(ToolError::NotAToolUse) };` … `Ok(ContentBlock::ToolResult { tool_use_id: id.clone(), content: .into(), is_error: <…> })`. The destructure pattern and the `ToolResult` field set are fixed by Feature 1; this feature only fills the middle (run the search / fetch the URL). +- **`yaml_value_to_json`** (`src/content/conversation.rs:88`). Already the bridge from a tool's `serde_yaml_ng::Value` to `serde_json::Value`. `execute` reads its arguments out of `input: serde_yaml_ng::Value`; it indexes the value directly (`input["query"]`, `input["url"]`) the way the existing tests index `tool.input_schema["type"]` (`conversation.rs:835`), so no new bridge is needed to read a string argument. +- **The insurance-claim tool JSONs** (`e2e/insurance-claim/context/tools/lookup_policy.json`): `{ name, description, input_schema: { type: object, properties, required } }`. `web_search.json` / `web_fetch.json` mirror this byte-shape exactly so the e2e assembly's `kind: tools` resolver (Feature 1) parses them with the same `serde_yaml_ng` path. + +## Metrics — what "green" means + +- **Two unit tests pass, both network-free.** `web_search`'s unit test asserts it reads the `query` argument, calls the injected `SearchProvider`, and shapes the provider's results into a `ToolResult` echoing the call `id`. `web_fetch`'s unit test asserts it reads the `url` argument, calls the injected `Fetcher`, and shapes the body into a `ToolResult`. Both inject a hand-rolled fake (the `FakeScriptRunner` shape); neither opens a socket. A test that takes more than a few milliseconds means an unmocked client leaked in — a defect, per the project's mocking convention. +- **Error paths covered.** Each tool's `execute` has at least one test for the failure mode it owns: a missing/non-string argument (the tool builds an `is_error: Some(true)` result rather than panicking) and a provider/fetcher error (surfaced as a `ToolError` the run loop maps to `RunError::Tool`, *or* as an `is_error` result — the choice is fixed in Specification §"Error mapping"). +- **Fixtures parse.** `e2e/research/context/tools/web_search.json` and `web_fetch.json` deserialize into `ToolDefinition` via the same `serde_yaml_ng::from_str` path the assembly resolver uses (a fixture round-trip test, mirroring `conversation.rs:830`'s `lookup_policy.json` round-trip, guards this). +- **No live API in CI.** `mise run check` / `mise run test` / `mise run lint` green; `mise run format` clean. The `reqwest`-backed production adapters are compiled but never executed under `cargo nextest` — they have no covering test by design (same posture as `TokioScriptRunner`, whose realness is proven only by the gated integration test, not the unit suite). The Feature 1 feature test `tests/tool_loop.rs` stays green (this feature adds files; it does not touch the run loop). + +## Specification + +### Module layout + +One new file, `src/knowledge/tools/web.rs`, registered with `mod web;` in `src/knowledge/tools/mod.rs`.

Keeping them in one file (rather than `web/search.rs` + `web/fetch.rs`) matches `script_runner.rs`, which keeps its port, adapter, and data in one file; the file is small (well under the 800-line guide) and splits only if a tool grows. + +### The mockable seam (both tools) + +Each tool depends on a **port trait**, never on `reqwest` directly.

This is the same containment `TokioScriptRunner` enjoys — its realness is invisible to the unit suite. +- **Brave Search API fits a minimal vertical slice**: a single authenticated `GET https://api.search.brave.com/res/v1/web/search?q=…&count=…` with an `X-Subscription-Token` header, returning JSON with `web.results[]` rows carrying `title`, `url`, `description`. One request, one JSON decode, a key from an env var (`BRAVE_SEARCH_API_KEY`). No SDK, no OAuth, no pagination for v1. It maps cleanly onto `SearchHit { title, url, snippet }`. +- **It needs only crates already (or near-already) in the tree**: `reqwest` (in Cargo.lock, see §"Crates"), `serde`/`serde_json` (direct deps) to decode the response, and `url`/query building via `reqwest`'s own `.query(&[…])`. No new search-SDK dependency. + +The adapter reads the key once via `std::env::var("BRAVE_SEARCH_API_KEY")`; absent, `BraveSearchProvider::from_env()` returns a `SearchError::Request("BRAVE_SEARCH_API_KEY not set")` shape *only when invoked*, so merely constructing the tool in a no-search run never fails. (No live run happens in this project; this is the seam a future live run would use.) + +A vendor-neutral note: the port is the contract, not Brave. Swapping to Serper, Tavily, or an internal endpoint is a new adapter implementing `SearchProvider` — zero change to `WebSearch::execute` or the tests. That is the whole point of resolving the "(tbd)" as *a seam over a provider* rather than as a hard provider dependency. + +### web_fetch client, resolved + +**Decision: `reqwest` behind the `Fetcher` port, returning the raw response body text.** `ReqwestFetcher` holds a `reqwest::Client`, parses/validates the URL, issues a `GET`, and lowers the response into `FetchResponse { status, body, content_type }`. v1 returns the body **verbatim** (no HTML-to-text extraction — deferred, Summary) because the e2e never fetches a live page and a real research run is usable with raw text; adding a parser now is unearned complexity (no HTML parser is in the tree — §"Crates"). The tool annotates the result with the status and content-type so a downstream model can tell HTML from JSON from plain text. + +### Tool execute: `ToolUse(input) → ToolResult` + +Each executor implements `ToolExecutor::execute` (Feature 1's trait). The body, in three steps, reusing the Feature 1 destructure idiom: + +```rust +pub struct WebSearch { + provider: Box, +} + +#[async_trait::async_trait] +impl ToolExecutor for WebSearch { + async fn execute(&self, call: &ContentBlock) -> Result { + // 1. Destructure — identical to NoopToolExecutor (mod.rs:94). + let ContentBlock::ToolUse { id, name: _, input } = call else { + return Err(ToolError::NotAToolUse); + }; + + // 2. Read arguments out of `input: serde_yaml_ng::Value`. A missing + // or non-string `query` is a *tool-level* failure (the model + // sent a bad argument), surfaced as an is_error result, not a + // ToolError — see "Error mapping". + let Some(query) = input.get("query").and_then(serde_yaml_ng::Value::as_str) else { + return Ok(error_result(id, "web_search requires a string `query`")); + }; + let count = input.get("count").and_then(serde_yaml_ng::Value::as_u64) + .and_then(|n| u8::try_from(n).ok()) + .unwrap_or(DEFAULT_RESULT_COUNT); + + // 3. Call the port; shape the outcome into a ToolResult echoing `id`. + match self.provider.search(SearchQuery { query: query.to_owned(), count }).await { + Ok(results) => Ok(ok_result(id, render_hits(&results))), + Err(err) => Ok(error_result(id, &err.to_string())), + } + } +} +``` + +`render_hits` formats `SearchResults` into a compact, model-readable text block (one `title — url\nsnippet` per hit). `ok_result`/`error_result` are two small constructors over `ContentBlock::ToolResult { tool_use_id: id.clone(), content: text.into(), is_error }` — `ok_result` sets `is_error: None`, `error_result` sets `is_error: Some(true)`. `WebFetch::execute` is the same skeleton: read `url`, call `self.fetcher.fetch(...)`, render `status` + body into the result text, `is_error: Some(true)` on a `FetchError` or a non-2xx status. + +### Error mapping (which failures are `ToolError` vs `is_error` result) + +The seam is deliberate and matches the Anthropic loop shape (research.md [1]): + +| Failure | Surfaced as | Why | +|---|---|---| +| Block is not a `ToolUse` | `Err(ToolError::NotAToolUse)` | A harness invariant violation, never a model-recoverable condition — identical to `NoopToolExecutor` (`mod.rs:95`). | +| Missing/wrong-typed argument (`query`/`url`) | `Ok(ToolResult { is_error: Some(true) })` | The *model* sent a bad argument; the standard agentic recovery is to feed the error back as a `tool_result` so the model can retry. A `ToolError` would abort the whole run — too harsh for a recoverable model mistake. | +| Network / provider / decode failure | `Ok(ToolResult { is_error: Some(true) })` | Same reasoning: the model may pick a different query/URL. Keeps a transient outage from killing the run. (The project's "tool-call error recovery / `is_error: true` retry loop" is deferred — research.md "What is deferred" — so v1 simply *emits* the `is_error` result; it does not itself retry.) | + +`ToolError` is reserved for structural impossibilities (non-tool_use block). Everything data-driven becomes an `is_error` `ToolResult`. This mirrors `script_runner.rs`'s split exactly: `ScriptError` for structural runner failures, an `ExitDisposition` (data) for a checker that ran and failed. + +### Unit-test fake strategy + +Both fakes are hand-rolled in `web.rs`'s `#[cfg(test)]` module, copying `FakeScriptRunner` (`assertions.rs:2114`): a struct holding a `Mutex>` plus a `Mutex>` for argument assertions. + +```rust +#[cfg(test)] +struct FakeSearchProvider { + canned: Mutex>>, + calls: Mutex>, +} +#[async_trait::async_trait] +impl SearchProvider for FakeSearchProvider { + async fn search(&self, query: SearchQuery) -> Result { + self.calls.lock().unwrap().push(query); + self.canned.lock().unwrap().pop_front() + .expect("FakeSearchProvider: a canned result is available") + } +} +``` + +The tool under test is constructed as `WebSearch { provider: Box::new(FakeSearchProvider::new(vec![Ok(results)])) }`.

The `non_tool_use` rejection is already proven generically by `NoopToolExecutor`'s test (`mod.rs:182`) and is identical code; re-testing it per tool would be redundant (parsimony), so it is asserted once via a shared helper if at all — not duplicated six times. + +### Tool-definition fixtures (owned by this feature) + +Two files under `e2e/research/context/tools/`, byte-shaped like `e2e/insurance-claim/context/tools/lookup_policy.json`: + +```jsonc +// web_search.json +{ + "name": "web_search", + "description": "Search the web and return a ranked list of result titles, URLs, and snippets.", + "input_schema": { + "type": "object", + "properties": { + "query": { "type": "string", "description": "The search query." }, + "count": { "type": "integer", "description": "Max results to return.", "default": 5 } + }, + "required": ["query"] + } +} +``` + +```jsonc +// web_fetch.json +{ + "name": "web_fetch", + "description": "Fetch the contents of a URL and return the response body as text.", + "input_schema": { + "type": "object", + "properties": { + "url": { "type": "string", "description": "The absolute URL to fetch." } + }, + "required": ["url"] + } +} +``` + +The `name` strings (`web_search`, `web_fetch`) are the contract Feature 3's evals assert on (`must_call_tool: web_search`, `tool_call_order: [web_search, web_fetch]` — project plan §"Feature 3"); they must match the tool names the executors register under. The `input_schema` shapes match the arguments `execute` reads (`query`/`count`, `url`). A fixture round-trip test (`web.rs` or `conversation.rs`-adjacent, mirroring the `lookup_policy.json` round-trip at `conversation.rs:830`) deserialises each into `ToolDefinition` and asserts `name`/`input_schema["required"]`, so a future schema edit that breaks the contract fails loud. + +### Crates + +| Crate | In `Cargo.lock`? | Action | +|---|---|---| +| `reqwest` 0.13.3 | **Yes** — transitive via rig (`hyper-rustls`/`rustls` TLS already locked). **Not** a direct dependency. | **Add to `Cargo.toml`** as a direct dep, pinned to the locked line and matching its TLS backend: `reqwest = { version = "0.13", default-features = false, features = ["rustls-tls", "json"] }`. `default-features = false` + `rustls-tls` avoids pulling OpenSSL (rig already uses rustls); `json` enables `.json()` decode. This does **not** change the resolved version — 0.13.3 is already locked — only promotes it to a direct dependency. Noted explicitly per the "do not invent a crate/version; if a new dep is truly needed, add it to Cargo.toml explicitly and note it" instruction. | +| `serde` / `serde_json` | Yes — direct deps. | Reuse to derive/decode the Brave response struct. | +| `serde_yaml_ng` | Yes — direct dep. | Reuse to read `input["query"]`/`input["url"]` (already how the codebase indexes `serde_yaml_ng::Value`). | +| `async-trait` | Yes — direct dep. | Reuse for the two port traits and the `ToolExecutor` impls. | +| `thiserror` | Yes — direct dep. | Reuse for `SearchError`/`FetchError`. | +| `tokio` | Yes — direct dep (`rt`, `macros`, `time`). | `reqwest`'s async client runs on the existing tokio runtime; the unit tests use `#[tokio::test]` (already used at `mod.rs:137`). | +| HTML parser (`scraper`/`html2text`/…) | **No** — none in the tree. | **Not added.** v1 returns the raw body; HTML→text extraction is deferred (Summary). Avoids a heavy new dependency for a path the e2e never exercises. | +| HTTP-mock lib (`wiremock`/`mockito`/`httpmock`) | **No** — none in the tree. | **Not added.** The mock seam is the `SearchProvider`/`Fetcher` *trait* (hand-rolled fake), not a mock HTTP server — matching `FakeScriptRunner`. This is why the seam is a port, not a mocked `reqwest::Client`: no mock-server crate exists, and adding one to mock at the HTTP layer would be both a new dep and a worse seam (it would couple the test to `reqwest`'s wire behaviour instead of the tool's logic). | + +The only Cargo manifest change is promoting `reqwest` to a direct dependency. No new crate is downloaded; the lockfile's resolved set is unchanged. + +## Alternatives + +**Seam placement — port trait (chosen) vs mock the HTTP client vs no seam.** + +| Approach | Mock point | New deps | Verdict | +|---|---|---|---| +| **A: `SearchProvider`/`Fetcher` port + hand-rolled fake** | the tool's own trait dependency | none (reqwest promoted, already locked) | **chosen** — mirrors `ScriptRunner`/`FakeScriptRunner` (the established in-repo seam); tests assert *tool logic*, not wire behaviour; provider/client swap is a new adapter with zero test churn. | +| B: call `reqwest` directly in `execute`, mock with `wiremock`/`httpmock` | the HTTP wire | **adds** a mock-server crate | rejected — adds a dependency not in the tree, couples every unit test to `reqwest`'s request/response handling, and tests the network library rather than the tool. Breaks the "mock external deps behind a trait" convention `script_runner.rs` sets. | +| C: no seam — `execute` does real I/O, no unit test | n/a | none | rejected — the project plan mandates a per-tool unit test with mocked network (research.md "Do individual tools get individual tests? → Yes"; testing rule "mock ALL external deps"). A live test in CI violates the "NO live web/search calls" gate. | + +**web_search provider — Brave (chosen) vs Serper/Tavily vs rig built-in vs DuckDuckGo HTML scrape.** rig has no search API (verified — no search crate in Cargo.lock). A DuckDuckGo HTML scrape needs an HTML parser (not in the tree) and is brittle. Serper/Tavily are equally valid JSON APIs; Brave is chosen for a clean single-GET + header-key shape, but **the decision is contained by the port** — any of them is a drop-in `SearchProvider` adapter, and since CI never calls it, the choice carries no test or correctness risk. The meaningful resolution of the research "(tbd)" is *"a `SearchProvider` seam over a JSON HTTP search API,"* with Brave as the concrete v1 adapter. + +**web_fetch body — raw text (chosen) vs HTML→text extraction.** Extraction needs a new parser dependency for a path the e2e never runs and a live run tolerates as raw text. Deferred (Summary). Returning `status` + `content_type` alongside the body lets a later extraction pass slot in behind the same `Fetcher` port without changing `WebFetch::execute`. + +**Build vs off-the-shelf tool executor.** No off-the-shelf web-tool crate produces Ailly's `ContentBlock::ToolResult` shape or fits the injected-`ToolExecutor` contract; the tools are ~40 lines each over the existing `reqwest`. Building is correct. + +## Summary + +- **Mockable seam (resolved):** two port traits, `SearchProvider` and `Fetcher`, each with a `reqwest`-backed production adapter (`BraveSearchProvider`, `ReqwestFetcher`) and a hand-rolled fake in the unit test — mirroring `script_runner.rs`'s `ScriptRunner`/`TokioScriptRunner`/`FakeScriptRunner`. The mock point is the trait, not the HTTP wire, so no HTTP-mock crate is added and tests assert tool logic. CI makes zero live calls. +- **web_search provider (resolves research "(tbd)"):** a JSON HTTP search API behind `SearchProvider`, concrete v1 adapter targeting the Brave Search API (single authenticated GET, key from `BRAVE_SEARCH_API_KEY`). Contained by the port — swappable to Serper/Tavily/internal with zero test change; never exercised in CI. +- **web_fetch client:** `reqwest` behind `Fetcher`, returning the raw response body text plus status and content-type. +- **Tool mapping:** each `execute` destructures the `ToolUse` (Feature 1 idiom), reads its string argument from `input: serde_yaml_ng::Value`, calls its port, and returns a `ToolResult` echoing the call `id` — `is_error: Some(true)` for a bad argument, a non-2xx status, or a network/provider failure; `Err(ToolError::NotAToolUse)` only for a non-tool_use block. +- **Fixtures (owned here):** `e2e/research/context/tools/web_search.json` and `web_fetch.json`, byte-shaped like the insurance-claim JSONs; their `name` strings are the contract Feature 3's evals assert on. +- **Crates:** only change is promoting `reqwest` (already locked at 0.13.3 via rig) to a direct dependency with `default-features = false, features = ["rustls-tls", "json"]`; the resolved lockfile set is unchanged. No HTML parser and no HTTP-mock library are added. + +**Deferred (carried, not gold-plated in v1):** +- HTML→text extraction in `web_fetch` (raw body for v1; the `Fetcher` port absorbs a later extraction pass behind the same seam). +- A live integration test for `BraveSearchProvider`/`ReqwestFetcher` analogous to `tests/eval_script.rs`'s real-`python3` test (gated on a key; out of scope while CI stays network-free). +- Tool-call error *recovery*/retry on an `is_error` result — the run loop's job, already deferred at project altitude (research.md "What is deferred"). v1 only *emits* the `is_error` result. +- A real executor registry wiring `web_search`/`web_fetch` into `cli/run.rs` (Feature 1 ships the empty `NoopToolExecutor::default()` there; a registry is the project's named follow-on — project design §6). diff --git a/.ailly/developer/2026-06-14-A-tool-calls/feature-2-web-tools/plan.md b/.ailly/developer/2026-06-14-A-tool-calls/feature-2-web-tools/plan.md new file mode 100644 index 0000000..8c64ab6 --- /dev/null +++ b/.ailly/developer/2026-06-14-A-tool-calls/feature-2-web-tools/plan.md @@ -0,0 +1,258 @@ +# Implementation Plan: Feature 2 — Web tools + +**Design:** [design.md](design.md) | **Project plan:** [../plan.md](../plan.md) | **Feature 1:** [../feature-1-harness/design.md](../feature-1-harness/design.md) + +**User story:** A model issuing a `web_search` query or a `web_fetch` URL through the Feature 1 `ToolExecutor` loop receives a real `tool_result`, with each tool's logic exercised by its own network-free unit test. + +**No single feature test (by design).** Feature 2 has no one end-to-end feature test of its own; each tool's correctness is its own mocked unit test (feature-2 design §"Metrics", project design Features table row 2).

What is missing is the **project-level demonstration** that the whole `assemble → run → eval → report` loop scores real tool calls, exercised the way an Ailly user runs it from `ci.sh` — and the `e2e/research/` project the README already advertises but does not ship. + +This feature delivers three things: + +1. **`e2e/research/`** — a new in-repo e2e project: an assembly declaring `web_search` + `web_fetch`, a research prompt that needs both, an eval suite asserting `must_call_tool` + `tool_call_order`, a `ci.sh`, and the docs (`README.md`, `AGENTS.md`). It mirrors `e2e/insurance-claim/` and the DDD `research/e2e` layout. +2. **The insurance-claim structural multi-turn gate** — a CI gate over `e2e/insurance-claim/` proving the now-live tool-call assertions (`must_call_tool: lookup_policy`, `tool_call_order: [lookup_policy, lookup_claim_history]`, `must_not_call_tool: auto_approve`) fire on multi-turn tool conversations, and updating `README.md`'s now-stale "Current limitations" section. +3. **A Rust e2e test** mirroring `tests/e2e_delegate_52.rs` / `tests/e2e_patterns_eval.rs`, scoring the research suite over synthetic tool-call conversations. + +### The load-bearing gap: noop tool-result scripting + +The project plan's surfaced assumption (plan.md §Self-Review, §Controlling-agent review) is the real problem this feature solves: **the CLI `run` path cannot produce tool calls under a noop model.** Grounded in the code: + +- `open_engine_for_model("noop")` returns `NoopEngine::auto()` (`engine.rs:122-125`). `auto()` has `auto_fill: true` and an empty script queue; on every `complete()` it emits `ScriptEntry::AutoStamp(Content::Text(format!("{NOOP_MODEL}-{index}")))` (`engine.rs:255-257`). It can **only** produce `Content::Text("noop-N")` — never a `Content::Blocks([ToolUse{..}])`. +- `cli/run.rs:97` constructs `NoopToolExecutor::default()` — the **empty** executor (`tools/mod.rs:58-67`). Any `tool_use` it is handed returns `ToolError::NoopExhausted` (`mod.rs:104-113`), which bubbles as `RunCmdError::Tool`. +- The run loop (`conversation.rs:486-540`) only walks into the tool-turn branch when the just-filled slot carries `ToolUse` blocks (`:504-511`). Under `NoopEngine::auto()` no slot ever does, so the loop is a plain text-fill loop and the empty executor is never called — `tests/run.rs` and `tests/single_file...` prove this no-tool-call path is green. + +The consequence: a `ci.sh` cannot get a tool call out of `ailly run` against a `model: noop` conversation. The only two ways to script a tool call are exactly what `tests/tool_loop.rs` uses — `NoopEngine::from_scripts` (engine emits the `tool_use`) plus `NoopToolExecutor::from_scripts` (executor emits the `tool_result`) — and neither is reachable from the CLI, which hard-codes `NoopEngine::auto()` and `NoopToolExecutor::default()`. Feature 1 deliberately scoped a real CLI executor registry to a follow-on (F1 design §"CLI `run` wiring"; project design §6). This feature must demonstrate the tool-call shape **without** building that registry and **without** a live API. The resolution (below) is the pre-filled-fixture mechanism. + +## Prior Art (in-repo patterns this feature mirrors) + +- **`tests/e2e_delegate_52.rs` / `tests/e2e_patterns_eval.rs`** — the e2e Rust-test pattern: inline synthetic conversation YAML strings (each a complete `meta` + filled turns, `model: noop`), written to a tmp run dir, scored by calling `eval_run(EvalCmdArgs { project, suite, over })` against the real in-repo project's eval suite, then asserting `outcome.conversations_matched` / `assertions_passed` / `_failed` / `_deferred` and the report-JSON totals. The research e2e test mirrors this exactly, with `tool_use` blocks in the synthetic bodies so `must_call_tool` / `tool_call_order` fire. +- **`tests/tool_loop.rs`** (Feature 1 feature test) — the only working recipe for producing a tool call under noop: `NoopEngine::from_scripts(vec![CompletionResponse { content: Content::Blocks([ToolUse{..}]), .. }, CompletionResponse { content: Content::Text(..), .. }])` + `NoopToolExecutor::from_scripts([(tool_name, vec![result_string])])`. This feature's understanding of "what can emit a tool call" is grounded here. +- **`e2e/insurance-claim/`** — the structural model for a full in-repo e2e project: `AGENTS.md`, `assemblies/.yaml`, `prompts/.md`, `context/{system,tools,examples,knowledge}/`, `evals/.yaml` + `evals/reports/`, `ci.sh`, `.gitignore`. The research project copies this shape. Its `ci.sh` is the gate model: CUJ 1 `assemble` always runs; CUJ 2 `run` is gated on `ANTHROPIC_API_KEY` (or a project `.env`); CUJ 3 `eval`; CUJ 4 `report`. Both insurance-claim and research `ci.sh` invoke `cargo run --quiet -- -p "${project_dir}" ` from `repo_root`. +- **`~/devel/davidsouther/domain-driven-design/research/e2e/`** — the upstream research-eval layout (`assemblies/{discovery,baseline,invocation}.yaml`, `prompts//.md`, `evals/.yaml`, `evals/scripts/*.py`, `context/`, `ci.sh`, `AGENTS.md`, `.gitignore`). Ailly's `e2e/research/` borrows its directory shape but is scoped to one suite and the two web tools (research.md "Research e2e scope? Two tools only"). +- **The internally-tagged `Assertion` schema** (`content/evaluation.rs`: `MustCallTool{tool}` :63, `MustNotCallTool{tool}` :67, `ToolCallOrder{sequence}` :75, all under `#[serde(tag = "type")]` :37). The research evals use `{ type: must_call_tool, tool: web_search }`, `{ type: must_call_tool, tool: web_fetch }`, `{ type: tool_call_order, sequence: [web_search, web_fetch] }` — the live `e2e/insurance-claim/evals/regression.yaml` is the working example. + +## Metrics — what "green" means + +- **`e2e/research/ci.sh` exits 0.** The assemble half always runs and asserts the expected conversation count; the run/eval/report half follows the insurance-claim gating (live model gated on `ANTHROPIC_API_KEY`, structural-noop half always runs). This is Feature 3's executable feature test. +- **The insurance-claim structural gate exits 0.** It proves `must_call_tool` / `tool_call_order` now *pass* on multi-turn tool conversations (the capability the README's "Current limitations" said was impossible), with no live API. +- **The Rust e2e test passes** *for the reason the suite is wired to test*: the research suite scores `must_call_tool: web_search`, `must_call_tool: web_fetch`, and `tool_call_order: [web_search, web_fetch]` as passing over synthetic tool-call conversations — modulo the pre-existing `over`-path harness limitation characterized below, which it shares with the other two `eval_*` tests and which this feature does not resolve. +- **No live API, no live web call.** Every gate and test runs through `NoopEngine` + `NoopToolExecutor` or over pre-filled fixtures. `mise run check` / `test` / `lint` green; `mise run format` clean; `cargo nextest run --all-features --all-targets` introduces no new failures. + +## Specification + +### Open #3 (resolved): the noop tool fixture is a pre-filled standalone conversation, committed under the project, NOT generated by `ci.sh` + +**Decision:** for both `e2e/insurance-claim` and `e2e/research`, the structural tool-call gate runs over **pre-filled, committed conversation fixtures** that already contain the full `user → assistant(tool_use) → tool(tool_result) → assistant(text)` shape with **no blank assistant slots**. `ailly run` is *not* used to produce the tool calls; it is either skipped in the structural gate or run as a verified no-op pass-through (zero blanks → byte-identical, proven by `tests/run.rs::no_blank_assistant_is_a_byte_identical_no_op`). `ailly eval` then scores the tool calls already present in the fixtures. + +This resolves the open-#3 standalone-vs-generated question and is forced by, and consistent with, the noop-scripting analysis in the Problem Statement: + +- **`ci.sh`-generated-with-injected-scripts is not reachable.** Generating the fixture from the assembly would require `ailly run` to emit a `tool_use`, which under `NoopEngine::auto()` is impossible (it only emits `Content::Text`). The CLI exposes no flag to inject a `NoopEngine::from_scripts` / `NoopToolExecutor::from_scripts`; building one is the deferred executor-registry / scripted-engine-source work (project design §6). A standalone pre-filled fixture sidesteps that entirely. +- **It honors the conversation-as-artifact guarantee.** A conversation file is the complete run artifact (README "Conversation-as-run-artifact replay"; project design §4). A committed conversation that already carries `tool_use → tool_result → text` *is* a valid run artifact — it is exactly what a live `ailly run` would have produced and saved. Scoring it with `eval` is the same code path that scores a freshly-run conversation; nothing about the fixture being hand-authored changes how `extract_tool_uses` reads it. +- **It mirrors the established e2e Rust-test convention.** `tests/e2e_delegate_52.rs` and `tests/e2e_patterns_eval.rs` already score **synthetic pre-filled conversation YAML** (with `tool_use` blocks, in delegate-52's case) over the real eval suites. The pre-filled-fixture mechanism is not a new idea; it is the convention these two tests already embody, extended to a shippable on-disk fixture and a `ci.sh` gate. + +#### The noop tool-result scripting mechanism, precisely + +The "scripted executor" the project plan asks about resolves to: **there is no executable blank for the executor to fill.** The mechanism is a pre-filled fixture conversation whose `tool_use` and `tool_result` blocks are authored literally, so: + +- the `tool_use` blocks are read by `eval`'s `extract_tool_uses` exactly as if a model had emitted them — `must_call_tool` and `tool_call_order` fire on them directly; +- the `tool_result` blocks sit in a `role: tool` message as data, satisfying the agentic shape for the structural assertion without any executor call; +- `NoopToolExecutor` (and thus the empty `default()` at `cli/run.rs:97`) is never invoked, because there is no blank assistant slot after a `tool_use` for the loop to fill — the fixture is complete. + +Contrast with how `NoopEngine::auto()` sources replies today: the engine *fills blank assistant slots* with `"noop-N"` text in call order (`engine.rs:255`); the run loop walks blank slots (`conversation.rs:491 while let Some(index) = self.next_blank_assistant()`). The pre-filled fixture has **no blank slots**, so the engine is never asked for a reply and the loop body never runs. The fixture *is* the script. This is the smallest mechanism consistent with the project's conventions: it reuses the synthetic-conversation pattern the e2e tests already use, adds no CLI surface, and builds no executor registry. + +(The alternative — a scripted CLI executor source, e.g. an `AILLY_NOOP_TOOL_SCRIPT` env var threaded into `cli/run.rs` to build a `NoopToolExecutor::from_scripts` plus a scripted `NoopEngine` — is rejected below as scope the project deferred. The pre-filled fixture obtains the same demonstration with zero new production code.) + +### `e2e/research/` layout + +Mirrors `e2e/insurance-claim/` and the DDD `research/e2e`.

Inline synthetic conversation YAML (the same shape as `fixtures/web-research.yaml`, with the two `tool_use` blocks and a final text turn), written to a tmp run dir, scored by `eval_run(EvalCmdArgs { project: e2e/research, suite: "research", over: })`. Asserts the research suite's three tool-call assertions are read and scored, and the report JSON is written at `evals/reports/.json`, with cleanup so the project tree stays pristine. + +**Known harness characteristic (shared, not introduced here):** because `over` is a tmp dir outside the project's `host_root`, `cli/mod.rs::project_relative` returns an empty `RunId` (`strip_prefix` fails → `unwrap_or_default()`), so `conversations_repository.list("")` does not find the tmp conversations and `conversations_matched == 0`. This is the identical limitation that makes `eval_insurance_claim.rs`, `e2e_delegate_52.rs`, and `e2e_patterns_eval.rs` all fail at baseline today (all three panic with `left: 0`). The research test is written to the same convention as those three. Resolving the `over`-path limitation is out of scope for Feature 3 (it touches neither tool calls nor `cli/mod.rs::project_relative`); the `ci.sh` structural gate — which runs over a run dir *inside* the project tree — is the authoritative tool-call demonstration and is unaffected by the limitation. The Rust test documents this with a comment pointing at the shared root cause, exactly as the existing two e2e tests' user-story headers describe their own harness assumptions. + +### Insurance-claim structural multi-turn gate + +Extend `e2e/insurance-claim/` with a committed pre-filled fixture and a structural `ci.sh` gate, parallel to the research project: + +- **Fixtures** (open #3, per-case): commit `e2e/insurance-claim/fixtures/{missing-fields,over-limit}.yaml` carrying the exact tool-call shapes the suite asserts — `missing-fields` emits `lookup_policy`; `over-limit` emits `lookup_policy` then `lookup_claim_history` in order. These reuse the synthetic bodies already proven in `tests/eval_insurance_claim.rs` (`CONV_MISSING_FIELDS`, `CONV_OVER_LIMIT`), promoted from inline test constants to on-disk fixtures. The `ambiguous` case calls no tool and is already covered by the existing eval; no tool fixture is needed for it. **No fixture emits `auto_approve`** — emitting it would fail the two `must_not_call_tool: auto_approve` assertions and invert the gate's intent (verified against `regression.yaml:12/18`). +- **`ci.sh` structural gate**: after the existing CUJ 1 assemble, add a noop structural step that copies the per-case fixtures into a run dir, runs `ailly run` as a verified no-op, runs `ailly eval regression --over `, and asserts via the report JSON that `must_call_tool: lookup_policy`, `tool_call_order: [lookup_policy, lookup_claim_history]`, and `must_not_call_tool: auto_approve` all pass (the suite's `judge` assertion on `over-limit` defers, as it does today — no engine wired). The existing live half (CUJ 2, gated on `ANTHROPIC_API_KEY`) is preserved unchanged. +- **`README.md` doc-sync**: the "Current limitations" section (`README.md:181-200`) is now stale. Feature 1 removed the `tools: Vec::new()` limitation; the first bullet ("Tool definitions are rendered into a system message... the rig adapter sends `tools: Vec::new()` unconditionally... `must_call_tool` and `tool_call_order` assertions fail") is rewritten to describe the now-live behavior: `kind: tools` resolves to `meta.tools`, the rig adapter forwards them, and the structural gate proves `must_call_tool` / `tool_call_order` pass on multi-turn tool conversations. The `judge`-deferred bullet stays (still true). Per the documentation-sync rule this edit ships with the gate, not as a follow-up. + +### Build steps (≤7; each leaves `check` + tests + scripts green) + +1. **`e2e/research/` skeleton** — `AGENTS.md`, `.gitignore`, `context/system/00-research-policy.md`, `prompts/web-research.md`; reference the on-disk `context/tools/*.json`. `assemble` produces one skeleton. +2. **research assembly + eval suite** — `assemblies/research.yaml` (declares both tools), `evals/research.yaml` (the three tool-call assertions). +3. **research noop fixture** — `fixtures/web-research.yaml` (the pre-filled multi-turn tool conversation; open #3). +4. **research `ci.sh`** — four-CUJ gate; structural-noop half always runs and exits green; live half gated on `ANTHROPIC_API_KEY`. +5. **`tests/e2e_research.rs`** — the Rust e2e test mirroring `tests/e2e_patterns_eval.rs`. +6. **insurance-claim structural gate** — promote the two per-case fixtures, extend `ci.sh`, doc-sync `README.md`. + +(Six steps; within the 7-step ceiling.

Feature 3 does NOT make it pass, and that is correct — it is a tolerated baseline failure shared by all three `eval_*` tests.** + +`:147` is `assert_eq!(outcome.conversations_matched, 3)`; it panics with `left: 0, right: 3`. Traced to source: + +- The test writes three synthetic conversations to a tmp dir (`tmp.path().join(run_id)`) that is **outside** the project root `e2e/insurance-claim`. +- `eval_run` resolves the listing key with `super::project_relative(&project, &args.over)` (`cli/eval.rs:102`). `project_relative` (`cli/mod.rs:15-30`) canonicalizes `over` and `strip_prefix`es the project host root; for a tmp dir outside the root, `strip_prefix` fails and it returns an empty `RunId` via `unwrap_or_default()`. +- `conversations_repository.list("")` then lists relative to the project root, not the tmp dir, finds none of the synthetic files, and `evaluate` reports `conversations_matched = 0`. + +This has **nothing to do with tool-call wiring.** The synthetic `CONV_*` strings parse fine (they use the same `tool_use`/`tool_result` block schema the live code reads), the `regression.yaml` suite loads fine, and `extract_tool_uses` / `check_must_call_tool` are already live (Feature 1). The failure is purely the `over`-outside-project path resolution. Proof it is shared and not tool-specific: `e2e_delegate_52.rs` (`:262`, `left: 0`) and `e2e_patterns_eval.rs` (`:284`, `left: 0`) fail identically at baseline, and **neither involves the insurance-claim project nor tool calls** — `delegate-52` and `patterns-eval` are unrelated e2e projects with their own (already-present) eval suites. + +Feature 3 does not touch `tests/eval_insurance_claim.rs`, `cli/eval.rs`, or `cli/mod.rs::project_relative`. The plan does not assign the `over`-path fix to this project (project design §6 lists no such item; research.md does not name it). The authoritative tool-call demonstration this feature ships — the insurance-claim and research `ci.sh` structural gates — runs `eval` over a run dir **inside** the project tree, where `project_relative` resolves correctly, so the gates prove the tool-call assertions pass without depending on the broken `over`-path. Fixing `:147` (and its two siblings) is a separate, pre-existing bug whose root cause and one-line locus (`project_relative` returning empty on an out-of-root `over`) are documented here for whoever picks it up; it stays a tolerated baseline failure for this project. + +## Pre-existing e2e characterization: `e2e_delegate_52` and `e2e_patterns_eval` + +Both fail at baseline for the **same** root cause as `:147` and are confirmed **out of tool-calls scope**: + +- `e2e_delegate_52.rs::delegate_52_slice_scores_corruption_suite_end_to_end` panics at `:262` (`assert_eq!(outcome.conversations_matched, 12)`, `left: 0`). It scores the `e2e/delegate-52/evals/corruption.yaml` suite (which exists on disk) over six synthetic conversations in a tmp dir. Same `over`-outside-root resolution → 0 matches. Delegate-52 is a document-corruption protocol fixture; it declares no tools and exercises program/judge scorers, not the tool loop. +- `e2e_patterns_eval.rs::patterns_eval_slice_evaluates_both_suites_end_to_end` panics at `:284` (`assert_eq!(discovery_outcome.conversations_matched, 6)`, `left: 0`). It scores `e2e/patterns-eval/evals/{discovery,invocation}.yaml` (both present) over synthetic conversations in tmp dirs. Same resolution → 0 matches. Patterns-eval is a skill-discovery/invocation fixture; no tools, no tool loop. + +Feature 3 touches neither project: it adds `e2e/research/`, two committed fixtures + a structural gate under `e2e/insurance-claim/`, and one new Rust test. It does not modify `e2e/delegate-52/`, `e2e/patterns-eval/`, `tests/e2e_delegate_52.rs`, or `tests/e2e_patterns_eval.rs`. These two remain tolerated baseline failures with the documented shared root cause; this feature neither fixes nor regresses them. + +## Alternatives + +| Approach | Tool calls in CI come from | New production code | Honors conv-as-artifact | Verdict | +|---|---|---|---|---| +| **A: pre-filled committed fixture + `eval`** | hand-authored `tool_use`/`tool_result` in a committed conversation; `run` is a no-op | none | yes (a complete run artifact) | **chosen** | +| B: scripted CLI executor source (`AILLY_NOOP_TOOL_SCRIPT` env → `NoopToolExecutor::from_scripts` + scripted `NoopEngine` threaded through `cli/run.rs`) | the CLI building a scripted engine + executor from an env var | a CLI flag/env, a scripted-engine source, executor threading | yes, but via new CLI surface | rejected — builds the deferred executor-registry/scripted-source machinery (project §6) for a demo; larger than the problem | +| C: live API only (`ANTHROPIC_API_KEY`) | a real model | none | yes | rejected as the *sole* path — research.md mandates a noop CI half ("noop run — no live API"); live stays an optional gated half | + +**Why A over B.** B is the literal "scripted executor sourced from X" the project plan flagged as a possible mechanism, but it requires a new CLI surface (an env var or flag), a way to source a scripted `NoopEngine` *and* a scripted `NoopToolExecutor` into `cli/run.rs` (which today hard-codes `NoopEngine::auto()` + `NoopToolExecutor::default()`), and the executor registry the project explicitly deferred (project design §6: "a real executor registry is a follow-on concern"). A obtains the identical demonstration — the `tool_use → tool_result → text` shape scored by `eval` — with zero production code, reusing the synthetic-conversation convention `tests/e2e_delegate_52.rs` already ships. YAGNI: the CI gate needs to *prove the assertions fire on the shape*, not to *re-derive the shape from a live loop*; the loop's correctness is already pinned by `tests/tool_loop.rs`. + +**Why A over C.** The research e2e must run in CI without credentials (research.md, project design Closing-Bell task 4 "Fully automatable — exits 0, no fix-ups"). C alone cannot. A runs unconditionally; C rides as the optional `ANTHROPIC_API_KEY`-gated half of the same `ci.sh`, identical to insurance-claim CUJ 2. + +**Build vs off-the-shelf.** No off-the-shelf harness produces a deterministic tool-call conversation that Ailly's `eval` can score; the fixture *is* the artifact, and authoring it is the smallest possible mechanism. + +## Summary + +- **Open #3 — resolved: pre-filled, committed standalone conversation fixtures, NOT `ci.sh`-generated.** Forced by the noop-scripting analysis: `NoopEngine::auto()` can only emit `Content::Text`, and `cli/run.rs` hard-codes the empty `NoopToolExecutor::default()`, so the CLI cannot produce a tool call. A complete pre-filled fixture (no blank assistant slot → `run` is a verified no-op; the fixture *is* the script) lets `eval` score `tool_use`/`tool_result` blocks directly. Both `e2e/research/` and `e2e/insurance-claim/` use this shape. +- **Noop tool-result scripting mechanism: a pre-filled fixture conversation with no executable blanks.** The executor is never called; `extract_tool_uses` reads the authored `tool_use` blocks exactly as it would model-emitted ones. This reuses the synthetic-conversation convention `tests/e2e_delegate_52.rs` / `tests/e2e_patterns_eval.rs` already embody, adds no CLI surface, and builds no executor registry — consistent with how `NoopEngine::auto()` fills blank slots (the fixture simply has none) and how `run` walks blanks (none to walk). +- **`:147` verdict: tolerated pre-existing failure, NOT fixed by Feature 3.** `conversations_matched == 0` because `over` is a tmp dir outside the project root and `project_relative` returns an empty `RunId`; the same root cause fails `e2e_delegate_52` (`:262`) and `e2e_patterns_eval` (`:284`). None involve tool-call wiring. The `ci.sh` structural gates run `eval` over an in-tree run dir where the path resolves, so they prove the tool-call assertions without touching the bug. +- **`e2e/research/` + the Rust e2e test + the insurance-claim structural gate** ship per the layout above, mirroring `e2e/insurance-claim/` and the DDD `research/e2e`. README doc-sync removes the now-stale "tools rendered as system text / `tools: Vec::new()`" limitation. No `src/` production changes; six build steps, within the 7-step ceiling. +- **Deferred (unchanged from project §6):** a real CLI executor registry and a scripted-engine CLI source (alternative B); the `over`-outside-project path fix in `project_relative` (the `:147` family bug); live-API CI as a mandatory rather than gated half. diff --git a/.ailly/developer/2026-06-14-A-tool-calls/feature-3-e2e-testing/plan.md b/.ailly/developer/2026-06-14-A-tool-calls/feature-3-e2e-testing/plan.md new file mode 100644 index 0000000..a750924 --- /dev/null +++ b/.ailly/developer/2026-06-14-A-tool-calls/feature-3-e2e-testing/plan.md @@ -0,0 +1,133 @@ +# Implementation Plan: Feature 3 — e2e + testing + +**Design:** [design.md](design.md) | **Project plan:** [../plan.md](../plan.md) | **Project design:** [../design.md](../design.md) | **Research:** [../research.md](../research.md) + +**Feature test:** `e2e/research/ci.sh` exits 0 (the Feature 3 executable feature test, design §Metrics). + +**User story:** an Ailly user clones the repo and runs `bash e2e/research/ci.sh`; the script drives `assemble -> run (noop, byte-identical no-op over a pre-filled tool fixture) -> eval -> report` and exits 0 without credentials or a live web call, with the eval report proving `must_call_tool: web_search`, `must_call_tool: web_fetch`, and `tool_call_order: [web_search, web_fetch]` passed on the multi-turn tool conversation. + +**Steps:** +- [ ] Step 0: No domain model / no production code +- [x] Step 1: `e2e/research/` project skeleton (assemble produces one skeleton) +- [ ] Step 2: research assembly + eval suite (declares both tools; three tool-call assertions) +- [x] Step 3: research noop fixture `fixtures/web-research.yaml` (pre-filled multi-turn tool conversation) +- [ ] Step 4: `tests/e2e_research.rs` (Rust e2e test mirroring `e2e_patterns_eval.rs`) +- [ ] Step 5: `e2e/research/ci.sh` (four-CUJ gate; structural-noop half always green; live half gated) — **passes the feature test** +- [x] Step 6: insurance-claim structural gate (per-case fixtures, extend `ci.sh`, doc-sync `README.md`) + +## Step 0: Domain model + +None.

A pre-filled fixture with **zero blank assistant slots** makes `run` a verified byte-identical no-op (`tests/run.rs::no_blank_assistant_is_a_byte_identical_no_op`); the loop body never runs and the empty executor is never called. `eval` then scores the authored `tool_use` blocks via `extract_tool_uses` (`assertions.rs:993`) exactly as if a model had emitted them.

This is the identical limitation that makes `eval_insurance_claim.rs` (`:147`), `e2e_delegate_52.rs` (`:262`), and `e2e_patterns_eval.rs` (`:284`) all assert `left: 0` at baseline. Write `tests/e2e_research.rs` to the **same convention** as those three, with a module-doc comment pointing at the shared root cause (design §"Known harness characteristic"). The authoritative tool-call demonstration is the Step-5 `ci.sh` gate, which runs `eval` over a run dir **inside** the project tree where `project_relative` resolves correctly; the Rust test mirrors the existing convention and is not the feature gate. **Resolving the `over`-path limitation is out of scope for Feature 3** (verdict below). + +**Red-first:** the test fails before `e2e/research/evals/research.yaml` exists (suite load fails) and before the synthetic body's tool blocks are scorable; it reaches its asserted state once Steps 2–3 are in place.

Four CUJs: + +1. **assemble** (always): `ailly -p . assemble research`; assert exactly one conversation skeleton lands under `runs//` (pure file read, no API), mirroring insurance-claim CUJ 1's nullglob count check. +2. **structural tool-call gate** (always, noop): copy `fixtures/web-research.yaml` into a fresh run dir `runs/-structural/web-research.yaml`; run `ailly -p . run runs/-structural/` as a **verified no-op** (fixture has no blank assistant, so `run` is byte-identical — assert the file is unchanged, e.g. compare a checksum before/after); then `ailly -p . eval research --over runs/-structural/` and read `evals/reports/.json` with `python3` (the DDD `ci.sh` heredoc pattern) asserting `totals.assertions.passed >= 3` and `totals.assertions.failed == 0`. This proves `must_call_tool` + `tool_call_order` fire on the multi-turn shape with no live API. +3. **live run** (gated on `ANTHROPIC_API_KEY` or a project `.env`): `ailly -p . run runs//` over the assembled skeleton, then `eval` + `report`; skipped with a clear notice otherwise, exactly like insurance-claim CUJ 2. +4. **report** (always, over the structural run): `ailly -p . report `; assert `evals/reports/-report.md` wrote (single-mode `report` writes `-report.md`, verified `report.rs:78`). + +**Verification (execution required, design §Metrics):** run `bash e2e/research/ci.sh` with `ANTHROPIC_API_KEY` unset and confirm it exits 0 with the assemble + structural + report halves all printing OK and the live half printing SKIP.

The `ambiguous` case calls no tool and is covered by the existing eval; no fixture needed. **No fixture emits `auto_approve`** — emitting it would fail the two `must_not_call_tool: auto_approve` assertions and invert the gate (verified `regression.yaml:12/18`). +- **Extend `e2e/insurance-claim/ci.sh`:** after the existing CUJ 1 assemble, insert a noop structural step that copies the two per-case fixtures into a fresh run dir, runs `ailly run` as a verified no-op (byte-identical), runs `ailly eval regression --over `, and asserts via the report JSON (`python3`) that the three tool-call assertions pass (the `over-limit` `judge` assertion defers as today — no engine wired). The existing live half (CUJ 2, gated on `ANTHROPIC_API_KEY`) is preserved unchanged. +- **Doc-sync `e2e/insurance-claim/README.md` "Current limitations":** rewrite the first bullet (`README.md:188-196`, currently "Tool definitions are rendered into a system message ... the rig adapter sends `tools: Vec::new()` unconditionally ... `must_call_tool` and `tool_call_order` assertions fail") to describe the now-live behavior: `kind: tools` resolves to `meta.tools`, the rig adapter forwards them, and the structural gate proves `must_call_tool` / `tool_call_order` pass on multi-turn tool conversations. The `judge`-deferred bullet stays (still true). Ships with the gate per the documentation-sync rule, not as a follow-up. + +**Red-first:** before the gate exists, `e2e/insurance-claim/ci.sh` has no structural step; add the python3-asserted structural block and confirm it would fail if a fixture (incorrectly) emitted `auto_approve` or omitted a required tool, then confirm green with the correct fixtures. Run `bash e2e/insurance-claim/ci.sh` (no key) and confirm exit 0 with the assemble + structural halves OK and the live half SKIP. + +**Runnable state:** new fixtures + script edit + doc edit; no Rust changes; `check`/`test` green; both `ci.sh` exit 0. + +--- + +## `eval_insurance_claim.rs:147` — out of scope (verdict) + +**Feature 3 does NOT fix `:147`, and that is correct** (design §"`:147` verdict"). `:147` is `assert_eq!(outcome.conversations_matched, 3)`, panicking `left: 0, right: 3`. Root cause: the test writes synthetic conversations to a tmp dir **outside** `e2e/insurance-claim`; `eval_run` resolves the listing key via `project_relative(&project, &args.over)` (`cli/eval.rs` `list_key`); `project_relative` (`cli/mod.rs:15-30`) canonicalizes `over`, `strip_prefix`es the project host root, and on failure (tmp dir outside the root) returns an **empty** `RunId` via `unwrap_or_default()`; `conversations_repository.list("")` then lists relative to the project root, finds none of the tmp files, and reports `conversations_matched == 0`. This is the `over`-outside-project path bug, shared identically by `e2e_delegate_52.rs:262` and `e2e_patterns_eval.rs:284`, and has **nothing to do with tool-call wiring**. Feature 3 touches none of `tests/eval_insurance_claim.rs`, `cli/eval.rs`, or `cli/mod.rs::project_relative`; the plan/research assign no `over`-path fix to this project. The Step-5/6 `ci.sh` gates run `eval` over a run dir **inside** the project tree where `project_relative` resolves correctly, so they prove the tool-call assertions without depending on the broken `over`-path. `:147` and its two siblings stay tolerated baseline failures; their one-line locus (`project_relative` returning empty on an out-of-root `over`) is documented for whoever picks up the separate bug. + +## Self-Review + +**Spec coverage** — every design §"Build steps" item maps to a step: research skeleton (Step 1), assembly + eval (Step 2), noop fixture (Step 3), Rust e2e test (Step 4), research `ci.sh` (Step 5), insurance-claim structural gate + README doc-sync (Step 6). The design's six build steps are preserved 1:1 (the design folds the Rust test into its own step here for an explicit red-green locus, staying within the 7-step ceiling at 7 steps including Step 0). The feature test (`e2e/research/ci.sh` exits 0) is Step 5's deliverable and is executed, not assumed. The `:147` verdict (out of scope) and the shared-harness characterization are carried verbatim from the design. + +**No production code** — confirmed against the design and live code: `cli/run.rs:97` already supplies `NoopToolExecutor::default()`, `Conversation::run` already owns the tool loop, and `web_search`/`web_fetch` + their JSONs are on disk. The noop-tool-result mechanism is the pre-filled fixture (no executable blanks), so no run/executor wiring is added. + +**Type / path consistency** — `must_call_tool`/`tool_call_order`/`must_not_call_tool` (internally-tagged `Assertion`, `evaluation.rs:63/67/75`), the `eval` report path `evals/reports/.json` (`cli/eval.rs`), and the `report` single-mode output `-report.md` (`report.rs:78`) are used consistently across Steps 2/5/6. The fixture block schema (`tool_use { id, name, input }` / `tool_result { tool_use_id, content }`) matches `CONV_OVER_LIMIT` in `tests/eval_insurance_claim.rs`. + +**Step ordering** — each step leaves `check`/`test` green: Steps 1–3 and 5–6 add only non-Rust project files (skeleton, assembly, eval, fixtures, scripts, doc), which cannot break the Rust build or suite; Step 4 adds one Rust test written to the existing tolerated-baseline convention. The feature test passes at Step 5; Step 6 extends the demonstration to insurance-claim and ships the doc-sync. diff --git a/.ailly/developer/2026-06-14-A-tool-calls/plan.md b/.ailly/developer/2026-06-14-A-tool-calls/plan.md new file mode 100644 index 0000000..207809f --- /dev/null +++ b/.ailly/developer/2026-06-14-A-tool-calls/plan.md @@ -0,0 +1,227 @@ +# Implementation Plan: Tool Calls + +*Cleared 2026-06-14 — controlling-agent review passed; load-bearing citations verified against HEAD (12cf2ed).* + +**Project design:** [design.md](design.md) | **Closing Bell:** [closing-bell.md](closing-bell.md) + +**Goal:** Wire end-to-end tool-call support so an assembly can declare tools, `ailly run` drives a multi-turn tool loop, and `ailly eval` scores the resulting tool calls. + +**Architecture:** Approach A from design §5. `assemble` resolves `PrefixBlock::Tools` JSON files into structured `Vec` written onto `meta.tools`; `run` reads `meta.tools` off the conversation file and forwards it on every `CompletionRequest` (`model.completion()` stays unary). `Conversation::run` owns the agentic loop: after a blank assistant slot is filled, any `tool_use` blocks are dispatched through an injected `ToolExecutor`, the results are appended as a `Role::Tool` message, a fresh blank assistant slot is appended, and the loop continues.

This plan is project-altitude: it fixes the Step-0 contract and the feature boundaries, names the deferred decisions each feature must resolve in its own design, and sketches each feature's ≤7 build steps. It does **not** lock per-step implementation code; that is produced by each feature's own `developer:plan` during build. The cleanup phase (`developer:cleanup` / `developer:refactor`) closes every feature cycle and is not enumerated per-step below; it is the named checkpoint that runs after each feature's build steps are green and before the next feature builds on it.

(Domain step; lands `ToolDefinition` in the module chosen by Feature 1's design per open #1 — the decision belongs to the design phase, the step only implements it.) +2. **`Meta.tools` field** — add the skip-when-empty field; the existing byte-identical round-trip and default-skip invariants still pass. +3. **`CompletionRequest.tools` + rig forwarding** — add the borrowed field; replace `rig_engine.rs:62` to lower and forward; existing rig translation tests stay green. +4. **`ToolExecutor` + `NoopToolExecutor`** — create `knowledge/tools/`; the noop executor serves scripted `tool_result`s in call order. +5. **Assembly resolves `Tools` to structured defs** — `PrefixBlock::Tools` parses JSON into `ToolDefinition`s onto `meta.tools` instead of a system-text message; assembly round-trip tests updated for the new render output. +6. **`Conversation::run` tool loop** — insert the tool-turn protocol; wire the executor per open #2; the feature test's session-shape assertion passes. +7. **CLI `run` wiring** — `src/cli/run.rs` forwards `meta.tools` and supplies the executor; `ailly run` against a noop conversation drives the loop end to end. + +**At-ceiling flag (7-step methodology limit):** Feature 1 sits exactly on the 7-step maximum with zero slack — it is the only feature delivering 6+ distinct contract artifacts, and two of these steps already bundle pairs (step 3: borrowed field + rig lowering; step 4: `ToolExecutor` trait + `NoopToolExecutor`). If Feature 1's own `developer:plan` finds any of these warrants its own step (e.g. the rig lowering, or non-trivial scripted-replies-in-call-order machinery in `NoopToolExecutor`), the build tips over 7 and **must return to design to simplify** per `developer:plan`. The pre-identified simplification is a feature-level split along the existing `content`/`knowledge` seam: a **schema half** (`ToolDefinition` + `Meta.tools` + the assembly `Tools`→structured-defs resolver) and an **execution half** (`ToolExecutor` + `NoopToolExecutor` + the `run` loop + rig forwarding + CLI wiring).

Feature 2's design must pick a provider (or a vendor-neutral seam over one) before the `web_search` unit test is written; the unit test mocks the provider per the project's external-dependency mocking convention, so the harness and e2e gates never make a live web call. **No internal prior-art seam to copy:** unlike `NoopToolExecutor` (mirrors `NoopEngine`) or the web tool JSONs (mirror the insurance-claim JSONs), `src/` has no existing HTTP/search-client module (verified — no `web*.rs`/`http*.rs` under `src/`), so Feature 2's design builds the provider seam from zero rather than mirroring an existing one.

The insurance assembly already declares `{ kind: tools, path: context/tools/*.json }`. The existing `evals/regression.yaml` spans three cases with distinct tool-call expectations: `missing-fields` asserts `must_call_tool: lookup_policy`; `ambiguous` asserts `must_not_call_tool: auto_approve`; `over-limit` asserts `must_not_call_tool: auto_approve` **and** `tool_call_order: [lookup_policy, lookup_claim_history]`. The gate therefore runs `assemble → run (noop) → eval → report` with per-case scripted noop replies — the positive cases emit `lookup_policy` (and, for `over-limit`, `lookup_claim_history` after it, in order), and **no case emits `auto_approve`** (emitting it would fail the two `must_not_call_tool` assertions and invert the gate's intent). The gate asserts the tool-call assertions fire on the multi-turn conversations. The existing live half (gated on `ANTHROPIC_API_KEY`) is preserved. The README's "Current limitations" section (`README.md:188-196`) currently states the rig adapter sends `tools: Vec::new()` unconditionally and consequently `must_call_tool`/`tool_call_order` assertions fail; Feature 1 removes that limitation and this gate makes those assertions pass, so the section is updated to reflect the now-live behavior. +- Create (shape per open #3): a noop conversation/script fixture for the insurance-claim structural gate. The fixture is per-case aware — the regression suite's three cases (`missing-fields`, `ambiguous`, `over-limit`) carry differing tool-call expectations, so the scripted replies differ per case rather than being one shared scripted conversation. + +**Feature-test intent:** the executable feature test for Feature 3 is that `e2e/research/ci.sh` exits green — it drives `assemble → run (noop) → eval → report` and asserts the report shows `must_call_tool` and `tool_call_order` passing on the noop-scripted conversation, with no live API call and no manual fix-ups. + +**Deferred design decisions to resolve in THIS feature's design:** +- **Open #3** — for `e2e/insurance-claim`, is the noop fixture a standalone YAML conversation file (e.g. under `e2e/insurance-claim/runs/fixture/`) or generated by `ci.sh` from the assembly with scripted replies injected?

Task 4 (the research journey from a clean clone) is the automatable portion — `e2e/research/ci.sh` exits green. Tasks 1, 2, 3 are exercised through the shipped `e2e/research/` and insurance-claim fixtures plus the amended `DESIGN.md` and `e2e/research/README.md` (the documentation the participant authors from). Task 5 (secondary, live insurance-claim run) is enabled but stays gated on `ANTHROPIC_API_KEY` and does not block the bell. + +--- + +## DESIGN.md change + +The `conversation` `meta` schema (`DESIGN.md:12`) gains `tools?: ToolDefinition[]`, with a `ToolDefinition` shape (`name` / `description` / `input_schema`) documented. The `assembly` prose that says "the engine treats every block as ordered text concatenated into the window" (`DESIGN.md:64`) is amended: `kind: tools` resolves to structured `ToolDefinition`s carried on `meta.tools`, not text — it is the one prefix-block kind that stops being concatenated system text. The agentic-loop shape (assistant `tool_use` → `Role::Tool` `tool_result` → next blank assistant turn) is documented alongside the existing "blank assistant slot" description (`DESIGN.md:37`). + +**This edit ships as part of Feature 1.** The schema change (`meta.tools`) and the `kind: tools` resolution change are introduced by Feature 1's code (the field, the assembly resolver, the loop), so the doc must move in lockstep with that code per the documentation-sync rule. Feature 3 adds only `e2e/research/README.md` (its own deliverable), not further `DESIGN.md` edits. + +--- + +## Closing Bell coverage matrix + +| Bell task | Tier | Feature that enables it | Automatable now | Human-study-only | +|---|---|---|---|---| +| 1.

Step-0 contract items (`ToolDefinition`, `meta.tools`, `CompletionRequest.tools`, `rig_engine` forwarding, `ToolExecutor` + `NoopToolExecutor`, the `run` loop) each appear in §"Step 0" with a signature and are delivered by Feature 1. The DESIGN.md change (design §"DESIGN.md change") has its own section and a ship-with-Feature-1 assignment. All three deferred decisions (open #1/#2/#3, research.md "Open for design") are named in their owning feature without being resolved here. Every Critical bell task (1–4) and the secondary task (5) appears in the coverage matrix with its enabling feature and its automatable-vs-human split. The Release-Flag decision (design §4 — no flag) is reflected in the architecture and the "releasable at every step" framing. + +**Placeholder scan** — no "TBD/TODO/implement later" left as a plan gap. The one genuinely open external choice (the `web_search` provider) is research.md's "(tbd)"; it is surfaced as a Feature-2-design decision, not papered over — that is a faithful relay of the source, not a plan placeholder. Deferred decisions are deliberately *not* resolved here because resolving them would pre-empt each feature's own design phase, which the design mandates. + +**Type consistency** — `ToolDefinition { name, description, input_schema }`, `Meta.tools: Vec`, `CompletionRequest.tools: &[ToolDefinition]`, `ToolExecutor::execute`, and `NoopToolExecutor` are used with identical names across Step 0, all three feature sections, the DESIGN.md section, and the matrix. Anchored code locations (`conversation.rs:444`, `engine.rs:24`, `rig_engine.rs:62`, `assembly.rs:243/254`, `cli/run.rs:94`) match the verified ground truth. + +**Assumption surfaced** — the design under-specifies how the CLI `run` path obtains a `ToolExecutor` for a noop conversation. Today `open_engine_for_model("noop")` yields `NoopEngine::auto()`, but there is no analogous executor factory, and the e2e gates run noop. This plan assumes the executor injection at `cli/run.rs` (and how the e2e noop gate scripts tool results) is settled by Feature 1's open-#2 resolution together with Feature 3's open-#3 fixture-shape decision; it is flagged so the owning feature designs address it rather than discovering it at build time. + +--- + +## Controlling-agent review (2026-06-14) + +A second review pass on top of the built-in 5-lens panel.

They operate on conversations (inspecting content, appending results) and are not part of the content schema or the engine adapter. + +## Search / Expand + +**LLM tool-calling pattern (Anthropic docs).** The canonical shape per the Anthropic API [1]: + +1. Send a request with `tools` array and the user message. +2. Claude responds with `stop_reason: "tool_use"` and one or more `tool_use` blocks. +3. Execute each tool; format outputs as `tool_result` blocks. +4. Send a new request with the original messages + assistant response + a user message with `tool_result` blocks. +5. Repeat while `stop_reason == "tool_use"`. Exit on `"end_turn"`, `"max_tokens"`, `"stop_sequence"`, or `"refusal"`. + +The `tools` parameter is **per API request**, not per conversation. The contract is: the caller provides the tool list on each individual completion call. This means tool offerings can differ across turns within a conversation — Claude only sees what is passed in the current request's `tools` array. + +**Rig's tool API.** Rig exposes an `AgentBuilder` with `.tools(...)` and a `.multi_turn(...)` path. The engine deferred note [3] names this as the reference when tools are wired. However, using `AgentBuilder` internalises the loop inside Rig, breaking Ailly's inline-trace guarantee (trace must be written to the conversation file after each assistant turn) and the mid-run save-on-progress guarantee. The correct path: keep `model.completion()` unary, pass `tools` on each call, detect tool calls in the response, execute them in the knowledge layer, and continue. This mirrors the Anthropic agentic loop shape exactly. + +**Scripted tool results for tests.** Standard pattern in major SDKs (Anthropic test helpers, LangChain `FakeTool`, AutoGen `FunctionTool`): a map from tool name to a deterministic response string or closure, consumed in call order or keyed by `(tool_name, call_index)`. + +**Research e2e reference.** The `domain-driven-design/research/e2e` project [4] is the structural model. It has `assemblies/`, `evals/`, `prompts/`, `context/`, and `ci.sh`. The Ailly `e2e/research/` project follows the same layout: one assembly that declares `web_search` and `web_fetch` tools; a prompt that asks a research question requiring both; evals asserting `must_call_tool: web_search` and `must_call_tool: web_fetch` (plus a tool_call_order assertion); a `ci.sh` that runs assemble → run (noop-scripted) → eval → report. The research e2e does NOT need to call a live web API; the point is that the harness routes tool calls to the noop executor and the eval assertions fire on the resulting conversation. + +## Falsification / Refine + +**Is this a bug, a feature, or a project?** Project. The schema, assertions, and e2e fixtures anticipate tool calls — the wiring is missing. Each tool group is a substantial amount of work.

Recursive globs (`**` patterns) + +**Status:** Out of scope.

Per-prompt cache strategy + +**Status:** `Prompts<'_>` exists as a separate sub-handle on `Project` so that prompt-side divergence is cheap (e.g., file-level content addressing for prompt deduplication, hashed cache keys). No divergence in the current slice — `Prompts` is structurally identical to `Context`. + +**Trigger to revisit:** A consumer wants prompt-level caching that differs from `context/` (e.g., a large-prompt dedup pass, or a content-hash key for cache-breakpoint stability across runs). When that consumer lands, the sub-handle is already in place to grow its own behavior without touching `Context`. + +## 3. `RemoteAssemblyRepository` + +**Status:** The `AssemblyRepository`, `EvaluationRepository`, `ContextRepository`, `PromptsRepository`, and `ConversationRepository` traits remain open to network-backed adapters, but only `vfs`-backed implementations land in this slice. The Repository pattern is named in `TASKS.md` for exactly this future shape. + +**Trigger to revisit:** The agent-based-eval workflow (or any other) needs a project served from a remote URL (HTTP-backed assemblies, S3-hosted context, etc.). When that consumer lands, implement the repository trait against the network adapter and inject it via `Project::open` (or a new `Project::open_remote` constructor); the sub-handle interface should not need to change. + +## 4. Project schema validation at open + +**Status:** `Project::open` only checks that the root exists and is a directory. It does not check that any subfolder exists or that any file parses. The first call to `assemblies().get(...)` is the first parse. This matches the YAGNI principle: parse errors surface where the parse happens. + +**Trigger to revisit:** Early-fail behavior becomes a UX requirement (e.g., users want `ailly assemble` to fail fast on a typo'd assembly name before doing any rendering work, with a "did you mean X?" suggestion). At that point, add a schema-validation pass to `Project::open` or a separate `Project::validate` method; do not put it in the hot path unless explicitly requested. + +## 5. Atomic `save` on `MemoryFS` + +**Status:** `VfsPath::move_file` is atomic per backend, not across backends. The "same-file collision" caveat from `FsConversationRepository::save` documentation carries forward to the `vfs`-backed adapter; cross-process atomicity guarantees are unchanged. Concurrent writers within a single process against the same `MemoryFS` mount are not protected; tests are single-threaded against each `Project::open_memory` value. A multi-threaded test that shares a `Project` is undefined behavior. + +**Trigger to revisit:** A concurrent-`ailly run` use case appears (e.g., a parallel matrix-binding execution that writes to the same `runs/` directory from multiple threads, or a multi-process orchestration). At that point, decide whether to add per-`RunTx` locking, switch to a content-addressed run-id scheme that makes collisions impossible by construction, or document the constraint as a hard precondition of the CLI shape. diff --git a/.ailly/developer/TASK-NOTES-tool-calls-additional-tools.md b/.ailly/developer/TASK-NOTES-tool-calls-additional-tools.md new file mode 100644 index 0000000..13f37ea --- /dev/null +++ b/.ailly/developer/TASK-NOTES-tool-calls-additional-tools.md @@ -0,0 +1,75 @@ +# Follow-on project: Additional tool implementations + +Seeds for the tools deferred out of the **tool-calls** vertical-slice project +([.ailly/developer/2026-06-14-A-tool-calls/design.md](2026-06-14-A-tool-calls/design.md)). +That project delivers the harness (Step-0 contract: `ToolDefinition`, `meta.tools`, +`ToolExecutor`, the `Conversation::run` tool loop, `NoopToolExecutor`) plus the two +web tools and the e2e.

If a future sweep pins a different output language, each checker needs a language branch or a per-language sibling. **Trigger:** a patterns-eval sweep pins a non-TS output language. + +- **patterns-eval structural-checker fragility** — The live falsification gate in [e2e/patterns-eval/ci.sh](../../e2e/patterns-eval/ci.sh) passes but with a thin, variable margin: `improved` ranged 1–3 across live runs and the gate survives largely on the LLM-as-judge assertion. The regex/heuristic `check_*.py` checkers reliably discriminate only `emitting-logs`, and even there a capable model's idiom variation (a bare `name:` event field, `Brand<>` helpers, expression-bodied arrow constructors) intermittently fails the invocation arm. `newtype` is an intentional null result (both arms pass). Decide whether to (a) lean the structural assertion on the judge and demote the script checkers to advisory, (b) pin model temperature/seed so the gate is reproducible, or (c) accept occasional gate flake and document it. Current framing is in [e2e/patterns-eval/AGENTS.md](../../e2e/patterns-eval/AGENTS.md) "Reading the invocation comparison". + +- **ailly-skill-eval paired-skills split** — The [skills/ailly-skill-eval/SKILL.md](../../skills/ailly-skill-eval/SKILL.md) is intentionally holistic. If its body grows a standalone "before you start, set up the project" section that would repeat on every use, split into a bootstrap skill and a per-call-site skill under `general:writing-paired-skills`. **Trigger:** the SKILL.md body acquires a setup procedure section. + +- **template variables in prefix/turn contents** — Today [DESIGN.md](../../DESIGN.md) templates only `path?` with matrix variables (the `PrefixBlock.path` and user-turn `TurnTemplate.path` lines); file *contents* are concatenated verbatim. A prompt authored with `{{var}}` placeholders — e.g. an externally-hosted system prompt carrying `{{currentDate}}` / `{{readOnlyInstructions}}` — cannot be filled by Ailly, so a harness must pre-render it outside the tool. Add a content-templating mechanism: fill `{{var}}` inside prefix-block and turn contents from a values source (an assembly-level `vars:` map, the per-binding matrix values, and/or `--var`), with an explicit choice on un-provided placeholders (leave verbatim vs error) and on delimiter collision with the existing `{{ matrix }}` path syntax. This lets an assembly reference a source prompt file directly and lets a variable like read-only mode become a clean matrix axis. **Motivating case:** the Scout Ailly prompt-eval framework (Scout repo `.ailly/developer/2026-06-08-A-prompt-eval/design.md`) first hit this — its Analyst prompt carried `{{currentDate}}`/`{{readOnlyInstructions}}` — but sidestepped it by dropping those (unused) variables and referencing the prompt directly with `kind: external`. The gap remains for any harness whose referenced prompt carries *meaningful* placeholders that must be filled at assemble time. **Trigger:** a harness needs Ailly to fill placeholders inside a referenced prompt file. + +- **whitespace-tolerant text assertions** — `text_contains` and `text_matches` ([DESIGN.md](../../DESIGN.md) text-assertion lines; [src/knowledge/assertions.rs](../../src/knowledge/assertions.rs)) match the raw response bytes, so a needle that spans a line wrap or differs only in run-length of spaces/newlines misses. Make both tolerant of insignificant whitespace: collapse runs of whitespace (spaces, tabs, newlines) to a single space in both the candidate text and the `value`/`pattern` before matching, so an expected phrase matches regardless of how the model — or a source prompt — wrapped it. Decide whether this is the default (changes existing semantics; needs a sweep of current e2e assertions) or an opt-in per-assertion flag alongside the existing `case_sensitive?` (e.g. `normalize_whitespace?: bool`), and how it interacts with a `text_matches` pattern that intentionally encodes `\s`/`\n`. **Motivating case:** the Scout prompt-eval suite must assert the Analyst decline phrase, which the source prompt hard-wraps as `I'm sorry, I can't help with\n that.`; without normalization the case needs a hand-written `\s+` pattern instead of the literal string. **Trigger:** an assertion needs to match text whose only difference from the expected value is whitespace/wrapping. + +- **eval `--over` outside the project root** — `ailly eval --over ` resolves the run directory through [`project_relative`](../../src/cli/mod.rs#L15), which returns an empty key when `` is not under the project's host root. The empty key makes [`VfsConversationRepository::list`](../../src/content/repository.rs#L128) read the project root instead of the run dir, so it matches 0 conversations and the eval silently scores nothing. The handler should resolve `--over` from the given path directly — e.g. root the conversations repository at `args.over`, or have `project_relative` preserve an absolute key and `dir_for`/`list` resolve it — rather than assuming `over` lives under the project. **Symptom:** three integration tests encode this shape (project at the real `e2e/`, `over` at a tempdir outside it) and are RED on `main_two`: [tests/eval_insurance_claim.rs](../../tests/eval_insurance_claim.rs), [tests/e2e_patterns_eval.rs](../../tests/e2e_patterns_eval.rs), [tests/e2e_delegate_52.rs](../../tests/e2e_delegate_52.rs), each asserting a non-zero `conversations_matched` against 0. **Trigger:** an operator (or a test) points `--over` at a run dir outside the project tree. *Re-confirmed still RED on branch `2026-06-14-A-tool-calls` (2026-06-15) during the tool-calls slice: `tests/eval_insurance_claim.rs:147` (`0` vs `3`), `tests/e2e_delegate_52.rs:262` (`0` vs `12`), `tests/e2e_patterns_eval.rs:284` (`0` vs `6`) — root cause is [`project_relative`](../../src/cli/mod.rs#L15) returning an empty `RunId` via `unwrap_or_default()` for an out-of-root `over`. The tool-calls e2e gates deliberately sidestep it by pointing `--over` at **in-tree** run dirs, so `e2e/research/ci.sh`, the insurance-claim structural gate, and `tests/e2e_research.rs` all score correctly without the fix. Scoped out of the tool-calls slice (no lineage); ready to pick up as a standalone one-locus fix.* + +## Deferred + +- **content/conversation deferred decisions** — Five revisit-after items carried over from the conversation design doc: typed `ImageSource`, narrowing `tool_result.content`, closing `TraceEvent` into a named enum, promoting `Conversation` to an aggregate root, and lifting blank/filled `Message` into type-states. See [TASK-NOTES-conversation-deferred.md](TASK-NOTES-conversation-deferred.md) for trigger conditions per item. +- **content/evaluation deferred decisions** — Three revisit-after items carried over from the evaluation design doc: `ToolCallSpec` extension, `f64` on `TextSemanticMatch.threshold` (and the resulting `PartialEq` rather than `Eq` derivations), and strict `ScriptBody` exclusivity. (The fourth original item, semantic validation on assertion shapes, was resolved by eval-assertions-core in favor of executor-level `Malformed` outcomes.) See [TASK-NOTES-evaluation-deferred.md](TASK-NOTES-evaluation-deferred.md) for trigger conditions per item. +- **knowledge/assertions deferred decisions** — Four revisit-after items carried over from the eval-assertions-core design doc: cache-hit token budgets, first-result vs all-results quantifier on `json_path`, reason-string format stability, and `tool_call_order` strict-contiguous variant. See [TASK-NOTES-assertions-deferred.md](TASK-NOTES-assertions-deferred.md) for trigger conditions per item. +- **knowledge/eval-script deferred decisions** — Eight revisit-after items carried over from the eval-script design doc: per-assertion `timeout_ms` override, suite-level `pass_env` defaults plus a denylist, hermetic `Program` resolution, runtime-version pinning via project config, stdout streaming into the report, an opt-in shared script library outside the project root, the Approach-2 `ScriptContext` bundle refactor, and full stderr surfacing. See [TASK-NOTES-eval-script-deferred.md](TASK-NOTES-eval-script-deferred.md) for trigger conditions per item. +- **engine deferred decisions** — revisit-after items across the engine-provider and engine-rig design docs: keyed `NoopEngine::from_table` constructor, `open_engine` bootstrap helper, `Conversation::request_at` on the aggregate, promoting `tokio` from dev-dep to runtime dep, live wire-up for OpenAI / Gemini / Bedrock, `Message.cache` forwarding into the Rig request, streaming, tool-definition wiring on requests, and the `RateLimited` quota vs request-rate distinction. See [TASK-NOTES-engine-deferred.md](TASK-NOTES-engine-deferred.md) for trigger conditions per item. +- **eval-cmd deferred decisions** — Five revisit-after items carried over from the eval-cmd design doc: per-class drill-down for `script` and `program`, report streaming, `--report-dir` override, exit code for deferred-only outcome, and `run_id` source. See [TASK-NOTES-eval-cmd-deferred.md](TASK-NOTES-eval-cmd-deferred.md) for trigger conditions per item. +- **project-layout deferred decisions** — Five revisit-after items carried over from the project-layout design doc: recursive `**` glob support, per-prompt cache strategy, `RemoteAssemblyRepository`, project schema validation at `Project::open`, and concurrent-writer atomicity on `MemoryFS`. See [TASK-NOTES-project-layout-deferred.md](TASK-NOTES-project-layout-deferred.md) for trigger conditions per item. +- **external-prefix-block deferred decisions** — Two revisit-after items from the `kind: external` prefix-block design (now landed; the third, configured source roots / Option B, is the standalone Follow-up above). (1) **Glob-over-external** — a glob-capable external block (the `System`/`Examples` shape) rather than the current single-file mirror of `File`. **Trigger:** a harness needs to pull many files from one external root. (2) **Policy to disable external blocks** — a project- or CLI-level switch that rejects `external` blocks outright. **Trigger:** CI or a published harness must guarantee a self-contained folder and forbid the `..`-escape.
