Subject: [PATCH] ci: add Claude Code GitHub Action
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two jobs in one workflow:

- `claude` — responds to @claude mentions in issues, PR comments and reviews.
- `review` — auto-reviews a PR when the `ready-for-review` label is added,
  reusing the repo's own checklist in .claude/commands/pr-review.md so the
  bot review and the local /pr-review pass apply the same conventions.

Requires an ANTHROPIC_API_KEY repository secret and the Claude GitHub App
installed on the org.

+            Review this PR against the repository's own review checklist.
+
+            1. Read `.claude/commands/pr-review.md` and follow it from the "What to check"
+               section onward, together with "How to write the comments" and "Output format".
+            2. Skip its "Gather the diff" section — that one assumes a local clone. Use
+               `gh pr diff` for the diff and `gh pr view` for the description and commits.
+            3. Read the full files at non-trivial change sites before judging them, and
+               check `docs/wiki/INDEX.md` for the touched module before claiming that a
+               helper, service, or entity does not already exist.
+
+            Post specific findings as inline comments citing path:line, and the summary as
+            a single top-level comment. Review only — do not modify files.
