+Manage a knowledge graph of architectural decisions, business rules, and workflow conventions extracted from spec files:
+
+```bash
+# Report available stewardship capabilities
+sds stewardship capabilities
+
+# Search for rules in the knowledge graph
+sds stewardship retrieve <query> --domain architecture
+
+# Persist a new rule
+sds stewardship store architecture --content "Use hexagonal architecture"

+# Extract decision candidates from a design.md or requirements.md
+sds stewardship extract .specs/changes/my-feature/design.md
+
+# Show rule provenance and version history
+sds stewardship trace <ruleId>
+
+# Retrieve context for a spec phase
+sds stewardship inject design
+
+# List, deprecate, or archive rules
+sds stewardship manage list
+sds stewardship manage deprecate --ruleId <ruleId>
+```
+
+These rules are automatically referenced by each spec-driven skill to give agents awareness of established project patterns.

 ## Long-Running Work
 
-For complex long-running tasks, SDS injects `long-running-work-planning`. It keeps agents working through durable artifacts, task status updates, checkpoints, and verification instead of relying on an external reasoning MCP server.
