+## Goal
+
+Add one bullet to the "Key Conventions" section of `CLAUDE.md` pointing agents and developers at ADR-022, the `evaluate-library` skill, and `docs/guides/adding-a-library.md`. No other changes to `CLAUDE.md`.
+
+## Why
+
+`CLAUDE.md` is the first file agents and developers read. Without a Key Conventions entry, the library evaluation policy is invisible to any agent starting a fresh session — it may run `pnpm add` without knowing the policy exists, and only hit the hook or pre-commit gate after the fact. The bullet closes the discoverability gap.
+
+## Done when
+
+- `CLAUDE.md` Key Conventions section contains a bullet: _"New runtime dependencies in feature- or core-tier packages require a library trace at `docs/library-decisions/<date>-<name>.md` produced by the `/evaluate-library` skill — see ADR-022 and `docs/guides/adding-a-library.md`."_ (exact wording may vary; substance must include ADR-022, the skill, and the guide path).
+- No other changes to `CLAUDE.md`.
+- `pnpm lint && pnpm fallow:audit` pass.
+
+## In scope
+
+- `CLAUDE.md` — one bullet in Key Conventions.
+
+## Out of scope
+
+- `docs/glossary.md` — the glossary entries for **Library trace** and **Pre-shipped trace** landed during the 2026-05-14 grill session and are already present.
+- Any other documentation changes.
+
+## Tasks
+
+- [x] Add the one-line library-policy bullet to CLAUDE.md Key Conventions (after confirming glossary entries are already present); all gates pass on this single commit.
