-            Review this pull request. Only comment on:
-            - Bugs or logic errors
-            - Security vulnerabilities (hardcoded secrets, injection, OWASP top 10)
-            - Breaking changes or regressions
-            - Sea Haven convention violations: kebab-case resource names, secrets in AWS Secrets Manager (not env vars or SSM), Lambda defaults (Python 3.12+/Node 22.x, arm64, explicit 60-day log retention)
-
-            Do NOT comment on:
-            - Style, formatting, or naming preferences
-            - Minor refactoring suggestions
-            - Performance unless it is a measurable regression
-            - Things that are already consistent with the existing codebase
-
-            Limit to 5 inline comments maximum. If the PR looks good, leave a single top-level comment saying so — do not force issues where there are none.
-
-            Use `gh pr comment` for top-level feedback.
-            Use `mcp__github_inline_comment__create_inline_comment` (with `confirmed: true`) for specific code issues.
-            Only post GitHub comments — do not submit review text as messages.
