Conciseness

The body is mostly dense, opinionated guidance that earns its place (severity taxonomy, change-size thresholds, dependency upgrade discipline), but the five-axis bullet lists restate generic review heuristics Claude already knows ('Are SQL queries parameterized?', 'Any N+1 query patterns?', 'avoid nested ternaries'), and the same ideas recur across sections — refactor-relocates-complexity and file-size concerns each appear in the Architecture section, 'Common Rationalizations', 'Red Flags', and the final checklist. This fits anchor 3 ('mostly efficient but includes some unnecessary explanation or could be tightened'); not 2 because there is no padded fluff or concept exposition, but the duplication and generic checklist content exceed the 'minor instances' bar of 4.

Actionability

Fully executable, copy-paste-ready artifacts throughout: the severity prefix table ('Critical:' / 'Nit:' / 'Optional:' / 'FYI'), concrete size thresholds ('~100 lines changed → Good'), a precise mutation-testing procedure ('Invert one condition the change adds (drop a negation, swap && for ||), run the suite, then restore the file from a copy'), a ready review-agent prompt, a fill-in dead-code report template, and a complete review checklist. Specific examples cover the common review cases; no significant gaps for an instruction-only skill.

Workflow Clarity

The Review Process is a clearly sequenced five-step workflow (understand context → review tests first → review implementation → categorize findings → verify the verification) with explicit validation checkpoints: the Step 2 mutation experiment, the Step 5 verification-story check, and the closing Verification checklist. Feedback loops are present ('A mutation that stays green is a finding: name the test case that is missing'), and the dead-code section adds an ask-before-deleting guard. This matches anchor 5 — clear sequence, explicit validation, feedback loops, and checklists for a complex process.

Progressive Disclosure

The skill is a single ~395-line monolithic SKILL.md: no references/, scripts/, or assets/ directories exist, yet the 'See Also' section points to '../../references/security-checklist.md' and '../../references/performance-checklist.md' — broken paths that also escape the skill directory two levels up. Detailed checklists that the skill itself defers to other skills ('For detailed security guidance, see security-and-hardening') remain fully inlined. This fits anchor 2 ('content that clearly belongs in separate files is inlined'); it cannot reach 3 because beyond the inlining, the only file-level references are broken, leaving no working navigation to deeper material.

Specificity

The description states the domain ('Conducts multi-axis code review') and one general action ('assess code quality across multiple dimensions'), but never names what the review actually does — the five axes, severity-labeled findings, or a review checklist are absent. This matches anchor 3 ('names domain and 1-2 concrete actions, but not comprehensive'); it is above 2 because reviewing diffs/PRs and pre-merge quality assessment are more than minimal generic action, but below 4 because no several specific concrete actions are enumerated.

Completeness

Both what and when are present: 'Conducts multi-axis code review' (what) plus four explicit trigger clauses — 'Use before merging any change', 'Use when reviewing code written by yourself, another agent, or a human', 'Use when asked to review a diff or a pull request, even when the diff is pasted inline'. Not 5 because the 'what' is abstract — it never enumerates concrete actions or outputs the way the 5-anchor example does ('extract text, fill forms, merge documents'), restating one action twice instead.

Trigger Term Quality

Natural phrases users would say are well covered: 'review a diff or a pull request', 'before merging', 'reviewing code written by yourself, another agent, or a human', 'code quality'. Good keyword coverage matching anchor 4; not 5 because common variations like 'review this PR', 'is this ready to merge', or 'code critique' phrasings are missing, though the coverage is otherwise strong.

Distinctiveness Conflict Risk

Distinct merge-gate triggers ('before merging any change', 'review a diff or a pull request') give it a recognizable niche, matching anchor 4 ('mostly distinct; minor overlap risk with closely related skills'). Not 5 because 'code review' is a broad domain with adjacent skills (security review, code quality, PR review) that share trigger vocabulary.
