Conciseness

The body is efficient and almost every token carries project-specific knowledge Claude cannot know (the protected-file table, dependency direction rules, template locations, the .squad/ leakage policy), with no padding of generic concepts. It sits at 4 rather than 5 because of minor trimmable over-explanation, e.g. 'Barrel files define the public API of a package' and 'Removing an export is a breaking change', which restate things Claude already knows.

Actionability

Guidance is fully concrete and executable: exact file paths in the protected-files table, the literal dependency direction to check ('squad-cli → depends on → squad-sdk'), a 5-step sweeping-refactor checklist with the exact marker string to scan for ('— zero dependencies'), five worked review examples with verdicts and recommendations, and a copy-paste output format template. This matches the top anchor of specific examples covering the common cases; as an instruction-only skill, absence of runnable code is not penalized.

Workflow Clarity

The eight patterns are each framed as explicit checklists ('Check every new import statement'), the sweeping-refactor pattern has a sequenced 5-step verification checklist, the examples demonstrate the reject/approve decision loop, and the Review Output Format section specifies verdicts, severities, and required fields. It does not reach 5 because there is no explicit ordering or triage flow connecting the eight checks into a single review pass (which check runs when, and what to do first when a PR matches several patterns).

Progressive Disclosure

No bundle files exist (no references/, scripts/, or assets/ directories), and the body is organized into well-labeled sections (Context, Patterns 1–8, Examples, Review Output Format, Anti-Patterns) with the one cross-reference — 'see architectural-proposals/SKILL.md' — clearly signaled and one level deep. It stays at 4 rather than 5 because the ~200-line body inlines everything, including the examples block and the protected-files table, some of which could be split into a reference file to keep the main file a leaner overview.

Specificity

The description names the domain ("review PRs for architectural quality") and lists several concrete focus areas — "module boundaries, dependency direction, export surface, pattern consistency" — which matches the anchor for several specific actions with minor gaps. It falls short of a 5 because it presents one action (review) with dimensions rather than the comprehensive multi-action coverage of the top anchor, and is above a 3 because the dimensions listed are concrete, not generic.

Completeness

The 'what' is clear (review PRs for architectural quality across four named dimensions) but there is no 'Use when...' clause or equivalent explicit trigger guidance anywhere in the description, which caps completeness at 3 per the judging guidelines. It is above a 2 because the 'what' half is concrete and multi-part, not vague.

Trigger Term Quality

Relevant keywords like "review PRs" and "architectural quality" are present, but common variations users would naturally say — "pull request", "code review", "refactor", "dependencies" as a standalone trigger — are missing, matching the 'some relevant keywords but missing common variations or synonyms' anchor. It is above a 2 because the terms present are natural, not jargon, and below a 4 because the vocabulary is narrow for such a broad trigger surface.

Distinctiveness Conflict Risk

The scope is mostly distinct — architectural review (boundaries, dependency direction, export surface) is distinguishable from general code-review, testing, or security-review skills, and the named dimensions narrow the niche. It does not reach 5 because 'review PRs' overlaps with any general PR-review skill and the description does not include trigger phrasing that would disambiguate which skill should fire for a routine PR review.
