What problem does it solve? Agent-generated and human-written code changes often ship with hidden defects, unproven claims, and security gaps that surface only in production. This Skill performs independent, findings-first review of diffs and PRs so correctness, safety, and data-loss risks are caught before merge. ## Core Features & Use Cases - Severity-ranked findings: Every issue is reported with a file/line anchor, impact, fix direction, and evidence, ordered Critical through Low, with summaries after findings. - Independent fresh-context review: Runs in a subagent, review agent, or separate session given only the diff, stated intent, and repo constraints, avoiding author-rationale bias. - Language-specific reviewer guides: Loads per-language references for Rust, Python, TypeScript, Ruby, Java, Kotlin, C#, F#, Bash, and SQL, plus security and proof-evidence passes on every review. - Use Case: After an agent implements a feature and tests pass, run this Skill on the branch diff to catch a missing authorization check, an unproven performance claim, and a speculative abstraction before requesting human merge approval. ## Quick Start Use the code-review skill to review my current branch diff for blocking correctness, security, and maintainability issues.
