Conciseness

The ~390-line body is mostly non-trivial policy guidance Claude would not inherently know, but it is noticeably repetitive: file-size guidance recurs in Change Sizing, the checklist, Red Flags, Common Rationalizations, and Verification, and the 'bump deps' material likewise appears three times. It is above the padded level 2 but clearly below the trimmed level 4.

Actionability

Concrete, executable artifacts throughout — a severity-prefix table with author actions, numeric sizing thresholds (~100/~300/~1000 lines), a splitting-strategy table, a copy-paste review-agent prompt, and a dead-code report template — with minor abstract gaps like "follow existing patterns". Not level 5 because several checklist and axis bullets remain directional rather than fully executable.

Workflow Clarity

The five-step Review Process is clearly sequenced with explicit checkpoints: severity labeling in Step 4, "Verify the Verification" in Step 5, and a final checkbox checklist covering Critical/Required resolution — matching the level-5 anchor of explicit validation steps, feedback loops, and checklists.

Progressive Disclosure

Sections are well organized and the "See Also" references are clearly signaled, but no bundle exists — the cited "../../references/security-checklist.md" and "../../references/performance-checklist.md" are dangling paths — and content that belongs in separate files (dependency upgrade workflow, change sizing) is fully inlined in the monolithic body. Structure exists but the split and the references are broken, matching level 3 rather than level 4.

Specificity

"Conducts multi-axis code review" and "assess code quality across multiple dimensions" name the domain and one to two actions, but they restate the same action rather than enumerating several concrete capabilities (the five axes are never named). It sits above level 2 (which names only a domain with generic actions) but below level 4 (which lists several specific actions).

Completeness

What it does ("Conducts multi-axis code review... assess code quality across multiple dimensions") and when to use it (three explicit "Use when..." clauses, including the edge case "even when the diff is pasted inline") are both clearly and explicitly answered with concrete trigger phrases, matching the level-5 anchor; the level-4 weakness ('when' could be more explicit) does not apply.

Trigger Term Quality

Natural phrases users would say are present — "reviewing code", "review a diff or a pull request", "before merging any change", "code quality" — but common synonyms like "PR", "LGTM", or "critique my code" are missing, so it falls short of comprehensive synonym coverage at level 5.

Distinctiveness Conflict Risk

A clear pre-merge code-review niche with distinct triggers (diff, pull request, merging, agent-written code), but it overlaps slightly with dedicated security- or performance-review skills it itself defers to, so it is mostly rather than fully distinct.
