+
+          Run these commands and observe their exit codes via the Bash tool —
+          not inferred:
+

+                  npm run format:check
+                  npm run build
+                  npm test
+
+          Hard rules:
+          - Run those commands yourself before every push. Do not push
+            if any of them is red.
+          - If \`npm install\` or \`npm ci\` is needed, run it first with
+            \`--no-audit --no-fund\` and confirm exit 0.
+          - Limit edits to compatibility shims (types, renamed exports,
+            breaking-change adjustments, eslint-config tweaks for new rule
+            defaults). Do NOT change product logic.
+          - Do NOT bump the package version.
+          - When all commands are green, push commits with your fixes
+            (if any). Do NOT try to trigger \`pr-checks\` yourself: a push
+            made with \`GITHUB_TOKEN\` does not start a workflow run, and
+            the \`pull_request\` run it queues stays in \`action_required\`.
+            This workflow re-dispatches \`pr-checks\` for you after this
+            step finishes.
+
+          ## MANDATORY final step
+
+          When you are done — whether you pushed fixes or determined no
+          changes were needed — you MUST post a status comment on the PR.
+          Run the following with the Bash tool:
+
+              gh pr comment "$PR_URL" --body "<your status summary>"
+
+          The comment must state plainly:
+          - Which command(s) failed initially (or "all green on first run").
+          - What changes you made (or "no fix needed").
+          - Whether you pushed any commits, and the SHA(s) if so.
+
+          Do NOT exit without posting this comment. The maintainer relies
+          on it to know what happened without reading the action log.
+
+          See CLAUDE.md in the repo root for the full project conventions.
