Conciseness

The body is dense and almost every line encodes a non-obvious rule Claude could not infer (scope-as-exclusions, format-before-regenerate ordering, deprecation marking), with no explaining of concepts Claude already knows. It is not 5 because the proportionality/'write for a future reader' guidance is restated three times across Step 6's Proportionality section, the Guidelines, and the Checklist, and could be tightened into one place.

Actionability

Commands are copy-paste ready ("git diff main..HEAD --name-only", "cd DOCS_PATH && git checkout main && git pull && git checkout -b {branch-name}-docs", "npx prettier --ignore-unknown --write <edited files>", "node scripts/gen-llms-txt.mjs"), the mapping procedure is a concrete ordered 6-step decision procedure with existence checks, and the output summary is a literal template. The template placeholders that remain ({branch-name}, profile dirs) are explicitly justified flexibility, matching the top anchor.

Workflow Clarity

Ten clearly sequenced steps with explicit validation checkpoints and feedback loops: verify path contains docs.json (Step 1), stop-and-report on missing profile, confirm every candidate page exists before editing (Step 4), fall through to search when a candidate doesn't resolve, unmapped files surfaced as Step 8 findings rather than dropped, format-before-regenerate ordering, a lint script that reports what CI will, and a final checklist. This matches the anchor for clear sequence with explicit validation and error-recovery loops.

Progressive Disclosure

The body is one ~340-line monolith with good internal headers, but it is far past the size where stable reference material (frontmatter conventions, llms.txt regeneration procedure, deprecation rules) belongs in separate reference files, and "See PROFILE_CONTRACT.md for what a profile must provide" points to a file that is not in this bundle — a dangling, unsignaled reference. This fits 'Some structure but could be better organized; references present but not clearly signaled' rather than 4, whose references are mostly clear and content mostly appropriately split.

Specificity

"Update documentation pages to match source code changes on the current branch" names the domain and one concrete, well-scoped action (updating doc pages against the branch diff), but lists no secondary actions (mapping files to pages, editing guides, reporting gaps). This matches the anchor 'Names domain and 1-2 concrete actions, but not comprehensive' — not 4, which requires several specific actions, and not 2, since the action is concrete rather than generic.

Completeness

The 'what' is clear (update doc pages to match branch changes), but there is no 'Use when...' or equivalent trigger guidance, which caps completeness at 3 per the judging guidelines. It is not 4 because the 'when' is entirely absent rather than present-but-imprecise.

Trigger Term Quality

Relevant keywords are present ("documentation", "source code changes", "current branch"), but common user phrasings are missing: "docs", "stale docs", "out of date", "sync docs with code". This fits 'Some relevant keywords but missing common variations or synonyms' rather than 4, whose keyword coverage includes the natural terms users would actually say.

Distinctiveness Conflict Risk

The niche — syncing documentation to a branch's source diff — is fairly distinct from generic doc-editing or writing skills, with differentiating terms like "source code changes" and "current branch". Minor overlap risk remains with general documentation-maintenance skills, so it fits 'Mostly distinct; minor overlap risk' rather than 5's 'clear niche with minimal conflict risk'.
