Conciseness

The body is dense and assumes Claude's competence — no explanations of git, Obsidian, or what documentation review is — with nearly every sentence carrying project-specific rules (tier definitions, MCP caveats, false-positive shapes). A few rhetorical framings ('a run that leaves a differently-shaped file has produced nothing, however good the review inside it') and the edit-discipline digression could be trimmed, which keeps it just below the 'every token earns its place' anchor.

Actionability

Fully executable throughout: a verbatim heredoc for the report skeleton, copy-paste git diff/comm/grep pipelines for claim cross-checking and broken-link detection, a claim-shape-to-check mapping table, a concrete finding block format, and a closing two-command verification with expected output ('Both must print 3'). Common cases are covered with specific commands rather than descriptions.

Workflow Clarity

Steps 0–5 are clearly sequenced with an explicit validation checkpoint at the end (the grep-count check before finishing) and real error-recovery paths: 'No step is a stop' gives a shell fallback for every check when the Obsidian MCP is absent, and known false-positive shapes are enumerated so findings can be corrected. The operation is read-only by default, so the destructive/batch cap does not apply.

Progressive Disclosure

The single bundle reference is real (references/checklist.md exists, 70 lines) and well signaled at the point of need — 'The full per-section checklist … is in references/checklist.md; on a --full sweep, work through it page by page.' It is exactly one level deep (the checklist points back to SKILL.md, not to further files), and the split is appropriate: the always-needed procedure stays inline while the per-page sweep checklist lives in the reference.

Specificity

The description lists multiple concrete actions covering the skill's full scope — 'Cross-checks every claim a page makes against the code, finds wikilinks and heading anchors the branch broke, checks frontmatter and page shape, and reports D-C/H/M/L findings in the four-field format' — all in third person. Anchor 4 ('minor gaps in coverage') fits worse since no capability area of the skill is left unnamed.

Completeness

It opens with an explicit trigger clause — 'Use when reviewing the documentation a branch changes … or sweeping the whole wiki with --full' — and then answers 'what' with concrete capabilities (claim cross-checking, broken wikilinks/anchors, frontmatter and shape checks, tiered findings). Both what and when are explicit with concrete trigger phrases, matching the top anchor.

Trigger Term Quality

Good natural-term coverage: 'reviewing the documentation a branch changes', 'AGENTS.md', 'READMEs', 'pages under wiki/', '--full', 'wikilinks', 'frontmatter' are phrases a user would plausibly say. A few common variants are missing (e.g. 'docs', 'stale docs', '.md'), so it falls just short of the 'comprehensive coverage including synonyms and file extensions' anchor.

Distinctiveness Conflict Risk

A clear niche with distinct triggers: branch-scoped documentation review of named surfaces ('AGENTS.md', 'READMEs', 'wiki/') with its own finding taxonomy ('D-C/H/M/L findings in the four-field format'). It would not naturally trigger for code review or general doc editing; conflict risk with generic review skills is minimal.
