Conciseness

The body is lean throughout: rules are one-liners ("Exact line numbers", "Concrete fix, not 'consider refactoring this'"), the Drop list enumerates filler phrases without explaining why they are bad, and no concept Claude already knows is re-explained. Every token earns its place, matching the anchor-5 'lean and efficient' standard; there is no padded section that would pull it to 4.

Actionability

Guidance is fully concrete and copy-paste ready for an instruction-only skill: an exact output template (`L<line>: <problem>. <fix>.`), four defined severity prefixes ("🔴 bug: — broken behavior, will cause incident"), and three ❌/✅ example pairs showing exactly how to transform verbose comments into the format. This matches anchor 5 ('specific examples cover the common cases') rather than 4, which would leave minor gaps in executable guidance.

Workflow Clarity

This is a simple single-purpose skill (under 50 lines, one task), so per the rubric's simple-skill exception workflow clarity can score 5 when the single action is unambiguous — and it is: format, severities, drop/keep lists, exceptions (Auto-Clarity), and boundaries are each explicitly scoped. The Auto-Clarity section even sequences the exception handling (drop terse mode for security findings, 'then resume terse for the rest'), and the skill involves no destructive or batch operations that would require validation checkpoints.

Progressive Disclosure

Per the rubric's guidance, a sub-50-line skill with no need for external references scores 5 with well-organized sections alone, and this body has exactly that: Rules, Examples, Auto-Clarity, and Boundaries are clearly headed, each small enough to belong inline, with no separate reference files needed or buried. There is no inlined content that should live in another file, so it does not fall to the anchor-4 'minor organization gaps' level.

Specificity

"Compressed code review - one line per finding with location, problem and fix" names the domain and specifies the exact output shape (per-finding line containing location, problem, fix), which is more concrete than the anchor-3 example ('Processes PDF files and extracts content'). It stays at 4 rather than 5 because it describes a single action's format rather than the multiple distinct actions in the anchor-5 example, leaving minor coverage gaps (e.g., severity tiers or multi-file format are not hinted at).

Completeness

It explicitly answers both questions: what ("Compressed code review - one line per finding with location, problem and fix") and when ("Use for /caveman-review, 'review this PR', or 'review the diff'") with concrete trigger phrases, exactly matching the anchor-5 good example pattern. It is not a 4 because the 'when' clause is already explicit and quoted, not merely present-but-vague.

Trigger Term Quality

"Use for /caveman-review, 'review this PR', or 'review the diff'" includes very natural phrases a user would actually say, matching the anchor-4 'good keyword coverage; a few natural terms missing' level. It is not a 5 because common synonyms like 'code review', 'review my changes', or 'look over this PR' are absent, so coverage is good rather than comprehensive.

Distinctiveness Conflict Risk

The named slash-command trigger and the compressed one-liner format carve out a mostly distinct niche, but 'review this PR' and 'review the diff' are generic review triggers that would also fire for any standard code-review skill, matching anchor 4 ('minor overlap risk with closely related skills'). It is not a 5 because those shared triggers leave more than minimal conflict risk with a sibling review skill; not a 3 because the format description and /caveman-review command clearly disambiguate intent.
