Code Review

Review code changes against the repository's architecture, security, convention, and quality standards. Produce actionable, categorized findings and a clear merge verdict.

Contract

Input — exactly one unit of review:

• a PR number (fetch the diff and metadata with gh pr diff {n} / gh pr view {n}),
• a branch name (review its diff against the merge-base with $BASE_BRANCH),
• an explicit commit range or diff,
• nothing — default to the current branch's diff against the merge-base with $BASE_BRANCH, including uncommitted changes.

Output — a review report in the format below, containing:

• a validation-gate table with the real pass/fail result of every configured command,
• findings grouped by severity (blocker / major / minor / nit), each with file, line, rationale, and a concrete fix suggestion,
• a breaking-change checklist,
• a verdict: approve or request changes (see Severity and Verdict).
