Conciseness

The body is efficient and assumes Claude's competence (terse bullets, ready-to-run git commands, no explanation of what git or diffs are), matching anchor 4. It is not anchor 5 because a few sentences restate the same point ("Start with no assumptions... not to rubber-stamp the diff" says one thing three ways) and lines like "A change that's correct on its own page can break the story told by a related page" merely recap the preceding bullets.

Actionability

The guidance is mostly executable: exact git commands for each review scope ("git diff --name-only main...HEAD", "git diff --unified=10") and concrete checks (grep for filename/anchors, verify URLs resolve). It stops short of anchor 5 because several verification steps remain high-level direction ("Trace through the common execution path", "verify against upstream docs or source code") without a specific procedure or example.

Workflow Clarity

Steps 1-7 are clearly sequenced (scope, read files, cross-references, factual verification, reader evaluation, code tracing, decision), each verification step is explicit (check URLs resolve, confirm flags exist, check anchor links match heading IDs), and the decision section is a concrete approve/request-changes checklist. This matches anchor 5's clear sequence with explicit validation steps and a checklist; no feedback-loop cap applies since the skill is read-only review, not destructive or batch.

Progressive Disclosure

The body is well organized into clear headed sections with no buried references and no content that obviously belongs in separate files, matching anchor 4's good structure with appropriately placed content. It does not reach anchor 5's fully-split ideal and exceeds the under-50-line simple-skill exception (the body is ~110 lines), though nothing here genuinely needs offloading to reference files.

Specificity

The description names a concrete scope ("uncommitted or recently committed documentation changes") and lists three specific evaluation criteria ("correctness, coherence, and style compliance"), giving several concrete actions with only minor coverage gaps. It falls short of anchor 5 because it offers a single review operation rather than multiple distinct concrete actions, and it exceeds anchor 3 since more than 1-2 specific actions/dimensions are explicitly named.

Completeness

Both "what" ("Review uncommitted or recently committed documentation changes for correctness, coherence, and style compliance") and "when" ("Use before creating a PR to catch issues") are explicitly stated, and four concrete trigger phrases ("review my changes", "review the diff", "check the fix before submitting", "does this look right") are included. This clearly matches anchor 5 — both what and when answered explicitly with concrete trigger phrases — and exceeds anchor 4, where the when-clause would be less explicit or lack trigger phrases.

Trigger Term Quality

Four natural, user-spoken trigger phrases are quoted ("review my changes", "review the diff", "check the fix before submitting", "does this look right"), which is good keyword coverage. It is not anchor 5 because common variations such as "proofread", "sanity check", or "review before merging" are missing, while it clearly exceeds anchor 3's partial keyword coverage.

Distinctiveness Conflict Risk

The "what" clause scopes the skill to documentation changes, but the trigger phrases ("review the diff", "review my changes") are unscoped and would equally fire for code-review skills, creating real overlap with closely related skills. This matches anchor 3 (somewhat specific but could still overlap with similar skills) rather than anchor 4, since the most likely trigger phrases are the ones shared with code-review skills.
