Precommit Checks

Run all quality checks on the mycelium codebase. Auto-fix issues where possible.

Steps

1. Lint + format — Fix lint and format issues automatically:

   cd fastapi-backend && uv run ruff check --fix . && uv run ruff format .
   cd mycelium-cli && uv run ruff check --fix . && uv run ruff format .
   

2. Type check (ty) — Both backend and CLI must come back clean. CI gates on this:

   cd fastapi-backend && uv run ty check .
   cd mycelium-cli && uv run ty check .
   

   Generated client (mycelium-cli/src/mycelium_backend_client/) is excluded via [tool.ty.src] since openapi-python-client templates produce diagnostics we can't fix without forking the generator. New diagnostics outside that path must be resolved before commit — don't paper over with # ty: ignore unless the underlying issue is a typeshed/library bug (CORSMiddleware add_middleware is the canonical example).

3. Tests — Run pytest:

   cd fastapi-backend && uv run pytest tests/ -x -q
   

4. Frontend — Type-check and build:

   cd mycelium-frontend && npx tsc --noEmit && npx next build
   

5. OpenClaw plugin tests — If any file under mycelium-cli/src/mycelium/integrations/openclaw/assets/mycelium/plugin/ was changed (source, test, or config), run the plugin's vitest suite:

   cd mycelium-cli/src/mycelium/integrations/openclaw/assets/mycelium/plugin && npm test
   

   If node_modules/ is missing, run npm install --silent first. Tests cover the pure routing logic (mentions, session-key format, channel config parsing, route decisions). Adding new message types or routing rules should come with tests in test/route.test.ts.

6. CLI docs — If any CLI command files were changed (mycelium-cli/src/mycelium/commands/):

   • Ensure new commands have @doc_ref decorators
   • Run /generate-cli-docs to regenerate the HTML CLI reference
   • If markdown source files changed (mycelium-cli/src/mycelium/docs/*.md), also run cd mycelium-cli && uv run python ../docs/generate_docs.py to regenerate the docs site (docs/index.html, docs/adapters.html, docs/reference.html). Use --page <learn|adapters|reference> to rebuild a single page. The script reads <!-- keep -->-marked hand-coded sections from the existing HTML — don't delete those files between edits.

7. Generated OpenAPI clients — Two clients are vendored from live OpenAPI specs. CI gates on the mycelium one being current; the CFN one is regenerated by hand when we bump the image.

   Mycelium backend → CLI client. If any backend schemas or routes changed (fastapi-backend/app/schemas.py, fastapi-backend/app/routes/), regenerate. The backend must be running locally first.

   docker compose -f mycelium-cli/src/mycelium/docker/compose.yml up -d mycelium-backend
   ./scripts/gen-mycelium-client.sh
   

   Writes to mycelium-client/mycelium_backend_client/ and mycelium-cli/src/mycelium_backend_client/. CI fails if the committed copy drifts from live /openapi.json.

   CFN client. If mycelium-cli/src/mycelium/docker/compose.yml was bumped to a new ioc-cognition-fabric-node-svc version, regenerate. The CFN stack must be running.

   docker compose -f mycelium-cli/src/mycelium/docker/compose.yml --profile cfn up -d
   ./scripts/gen-cfn-client.sh
   

   Writes to fastapi-backend/ioc_cfn_svc_api_client/. After regen, run cd fastapi-backend && uv run ty check . — type errors at CFN call sites in app/services/cfn_negotiation.py or app/services/cfn_knowledge.py mean CFN renamed/dropped a field and the call needs updating. The typecheck IS the contract test.

8. Docs consistency — If any user-facing behavior changed (commands renamed, new features, API changes), grep for stale references and fix them in:

   • docs/index.html (Learn), docs/adapters.html, docs/reference.html — main docs site (3 pages, generated)
   • docs/mycelium-dataflow.html — scrolly presentation deck
   • docs/demo-script.md — live demo script
   • README.md — quickstart and overview
   • mycelium-cli/src/mycelium/docs/ — built-in CLI docs
   • Adapter skills (mycelium-cli/src/mycelium/integrations/*/assets/skills/)

9. Doctor sanity check — If any file under mycelium-cli/src/mycelium/commands/doctor.py, mycelium-cli/src/mycelium/commands/adapter.py, or mycelium-cli/src/mycelium/integrations/openclaw/assets/ was changed, run mycelium doctor to verify every check still passes against the current install:

   mycelium doctor
   

   All checks should be green (✓). If any come back as warnings (~) or errors (✗), act on them before committing — doctor is the fastest way to catch adapter-install regressions (stale manifests, drift between installed vs packaged plugin, channel config issues).

   If you added new failure modes that doctor should catch, add a new check function to doctor.py following the _check_*() -> CheckResult pattern and register it in _run_all_checks(). Doctor is the user's first debugging tool — new silent-failure classes should land here alongside their fix.

10. Report — Summarize what was fixed and any remaining issues.
