GitHub - InnerAura/hyperweave: Headless visual output layer for AI agents. One API call → self-contained SVG. Zero dependencies, works everywhere ⌬

Headless visual output layer for AI agents.
One API call → self-contained SVG. No JavaScript. No dependencies. No runtime.
Works everywhere an <img> tag works.

The Problem

When an agent needs to produce something visual — a status card, a dashboard, a receipt of its work — it generates React, HTML, or pixels, locked in the environment that made it. Embed it in markdown, pass it to another agent — it breaks or loses context. There's no portable visual primitive for agents.

HyperWeave is that primitive. One API call returns a self-contained SVG with data binding, branding, and machine-readable metadata baked in. No JavaScript, no dependencies, no runtime. It renders in GitHub READMEs, Slack, Notion, docs, your site, email, VS Code, or terminal. Every surface that renders an <img> tag is a HyperWeave surface.

Agentic Artifacts

Every AI coding session produces a receipt — cost, tokens, tool distribution, session rhythm. One install, fully automatic.

hyperweave install-hook

_{262M tokens · 562 calls · 52 stages · $175 — voltage}

_{Rhythm strip — the same session data at 92px tall}

_{Same data, different livery — claude-code}

_{Codex transcripts auto-detect from the JSONL shape}

The livery matches the agent that produced the session:

Agent	Livery
Claude Code	`claude-code`
Codex	`codex`
—	`voltage`
—	`cream`

Auto-detected from the session transcript. Pin a different default with hyperweave install-hook --genome voltage.

Genomes — Aesthetic DNA

A genome is a portable, machine-readable aesthetic specification. It encodes the complete visual identity — chromatic system, surface material, motion vocabulary, geometric form language — as a set of CSS custom properties that any agent can consume and apply consistently across every artifact type.

Three production genomes ship today. Custom genome generation via AI skill files coming soon.

How It Works

Every artifact is the output of a single composition formula:

ARTIFACT = FRAME × PROFILE × GENOME × SLOTS × MOTION × ENVIRONMENT

Python builds context dicts. Jinja2 builds SVG. YAML defines config. Three layers, no mixing. Zero f-string SVG in Python.

ComposeSpec → engine.py → assembler.py (CSS) → lanes.py (validate) → templates.py (Jinja2) → SVG

Every artifact ships with:

Semantic metadata — provenance, reasoning, spatial trace, aesthetic DNA. Machine-readable context so the next agent in the chain knows what it's looking at and why.
CSS state machines — data-hw-status, data-hw-state, data-hw-regime drive visual transitions through the Custom Property Bridge. No JavaScript.
Pure CSS/SMIL animation — all motion uses compositor-safe properties (transform, opacity, filter). No script tags. Works inside GitHub's Camo proxy, email clients, Notion embeds — anywhere SVGs render.
Accessibility — WCAG AA, prefers-reduced-motion, prefers-color-scheme, forced-colors, ARIA markup. Structural, not decorative.

Dimension	Count
Frame types	9 (badge, strip, icon, divider, marquee-horizontal, stats, chart, receipt, rhythm-strip)
Genomes	3 (automata, brutalist, chrome)
Motion configs	6 (1 static + 5 border SMIL)
Glyphs	99 (93 Simple Icons + 6 geometric)
Divider variants	8 — 3 genome-themed (`band` chrome, `seam` brutalist, `dissolve` automata) + 5 genome-agnostic (`block`, `current`, `takeoff`, `void`, `zeropoint`) at `/a/inneraura/dividers/`
Metadata tiers	5 (Tier 0 silent → Tier 4 reasoning)
Bundled fonts	3 (JetBrains Mono, Orbitron, Chakra Petch — base64-embedded)

Stack: Pydantic, FastAPI, FastMCP v3, Jinja2, Typer.

Data Connectors

HyperWeave binds live data into any artifact through a unified token grammar (?data=...). Tokens are comma-separated; each token is either a literal (text:, kv:) or a live fetch (<provider>:<identifier>.<metric>).

Prefix	Source	Identifier shape	Metrics
`gh` / `github`	GitHub	`owner/repo`	`stars`, `forks`, `watchers`, `issues`, `license`, `language`, `build`
`pypi`	PyPI + pypistats.org	`package`	`version`, `license`, `python_requires`, `downloads`
`npm`	npm registry	`package`	`version`, `license`, `downloads`
`hf` / `huggingface`	HuggingFace Hub	`org/model`	`downloads`, `likes`, `tags`, `pipeline_tag`, `library_name`
`docker`	Docker Hub	`namespace/repo`	`pull_count`, `star_count`, `last_updated`
`arxiv`	arXiv API	`id` (e.g. `2310.06825`)	`title`, `authors`, `published`, `categories`, `summary`
`text`	literal	—	renders the payload as displayed text
`kv`	literal	`KEY=VALUE`	static role-tagged value

Live tokens cache for 5–10 minutes per provider. Failures cache for 60s and surface as the em-dash sentinel (—) instead of fabricating zero values. Each provider runs through its own circuit breaker so a single upstream outage cannot trip unrelated fetches.

Embedded commas inside text: and kv: values escape as \,.
