Conciseness

The body is efficient and assumes reviewer competence ('Most "looks wrong" findings die here — or get sharper'), but the 'Evidence, not speculation' and 'Confidence gate' sections partially restate the same rule about excluding unconfirmed findings. This fits anchor 4 ('minor instances of over-explanation that could be trimmed') rather than 5's 'every token earns its place'.

Actionability

Guidance is fully executable for an instruction-only skill: concrete commands ('git diff <base>...HEAD', 'gh pr diff', 'codewhale review --pr <N> --json'), a defined severity vocabulary (blocker/concern/nit), an exact output template, and named tool invocations. Per the code_vs_instruction note, absence of code is not penalized when guidance is this actionable.

Workflow Clarity

The hand-review workflow is a clear numbered sequence (establish the change → read callers and contracts → read error paths) with conditional fallbacks for tool availability, and the confidence gate acts as an explicit validation checkpoint with a defined escape valve ('considered, could not confirm') for unconfirmed items. This matches the 5 anchor's clear sequence with explicit validation steps.

Progressive Disclosure

The skill is a single self-contained file with no bundle directories and no references to any; nothing is inlined that belongs in a separate file, sections are well-organized and easy to navigate, and the body appropriately delegates to the shared 'codewhale review' core rather than duplicating it. This matches the 5 anchor's 'content appropriately split; easy navigation' given there is nothing to disclose further.

Specificity

The description lists multiple concrete actions — 'reads the codebase around the change — callers, contracts, and invariants', 'returns line-anchored findings ranked by severity with confidence, then a merge-risk verdict' — giving comprehensive coverage of what the skill does, matching the 5 anchor rather than 4's 'minor gaps'.

Completeness

It explicitly answers both what ('Diff-scoped correctness review that reads the codebase... returns line-anchored findings... then a merge-risk verdict') and when ('Use for reviewing a PR, diff, or named change set') with concrete trigger phrases, exactly matching the 5 anchor.

Trigger Term Quality

'Use for reviewing a PR, diff, or named change set' provides good natural keyword coverage, but common user phrasings like 'code review', 'review my changes', or 'staged changes' are absent. This fits anchor 4 ('a few natural terms missing') better than 5's 'comprehensive coverage including synonyms and file extensions', while clearly exceeding 3's 'missing common variations'.

Distinctiveness Conflict Risk

It carves a clear niche (diff-scoped correctness review) and adds explicit exclusions — 'Not for style review, approvals-as-rubber-stamp, or editing the code' — which sharply reduces conflict risk with adjacent skills, matching the 5 anchor ('clear niche with distinct triggers; minimal conflict risk').
