What problem does it solve? Code changes often ship with hidden bugs, security flaws, or resource leaks that manual review misses. This Skill performs a skeptical, evidence-based review of diffs, commits, PRs, or changed files, flagging only material defects with exact code citations and severity rankings. ## Core Features & Use Cases - Multi-phase defect sweep: Scans eight categories (correctness, null safety, concurrency, security, resource management, error handling, API misuse, data integrity) across up to 7 phases with ledger-based deduplication. - Structured report output: Writes a schema-conformant code-review-report.yaml with findings sorted by severity (Critical to Nit) plus suppressed findings with documented rationale. - Verdict generation: Produces a clear verdict (Request Changes, Comment, or Approve) derived strictly from confirmed, exploitable findings. - Use Case: Before merging a pull request, invoke the review to catch an unguarded null dereference or an unsanitized input reaching a SQL query, with exact file and line citations. ## Quick Start Ask the agent to review the current uncommitted changes or a specific pull request for bugs and security issues.
