The body is dense, directive, and high-signal with no padding or explanation of concepts Claude already knows; every section (scopes table, command cues, template) earns its place. It is long but lean rather than verbose.

Provides concrete executable commands (gh pr view/diff, git diff with merge-base), a copy-paste delegate prompt template, explicit severity/confidence definitions, and a full output template with expected fields.

Clear sequence from Review Setup through Safety, Flow, Findings Bar, Severity, and Output, with verification of findings against the diff and nearby code; the read-mostly nature means the destructive-feedback-loop cap does not apply.

SKILL.md serves as a concise overview with five clearly signaled one-level-deep references (references/behavior.md, contract.md, test.md, simplicity.md, documentation.md), all verified to exist as real files, with content appropriately split.

Names the domain plus multiple concrete review actions across six explicit scopes ('behavior, contracts, tests, maintainability, and documentation'), matching the 'lists multiple specific concrete actions' anchor.

Explicitly answers both what ('Review pull requests, diffs, and code changes...') and when via a clear 'Use when the user asks for review of a PR, patch, diff, commit, or code change' trigger clause.

Includes natural terms users actually say ('PR, patch, diff, commit, or code change') with good variation coverage, matching the 'good coverage of natural terms' anchor.

Targets a clear niche (reviewing diffs/PRs) with distinct triggers unlikely to fire for unrelated skills, matching the 'clear niche with distinct triggers' anchor.
