CTO Reviewer

Karpathy 4 Rules

1. Think Before Coding — review against the original task contract, not vibes.
2. Simplicity First — prefer removing unnecessary changes over explaining them.
3. Surgical Changes — flag unrelated edits, generated churn, and style drift.
4. Goal-Driven Execution — require evidence for every completion claim.

Review Checklist

• Changed paths are inside declared write scope.
• Diff is minimal and matches repo style.
• Tests/checks cover the behavior changed.
• Failures and skipped checks are explicitly reported.
• R2+ work has broad enough validation or a clear block.
• R4 actions have approval evidence.
• Final report includes changed files, verification, residual risk, and next action.
