Conciseness

Efficient and free of generic explanations — the file-to-doc mappings and flag-extraction guidance are repo-specific knowledge Claude does not already have. Minor trim opportunities keep it below anchor 5: the 12-line Step 7 example report block and "Apply the `documentation` topic" being stated in both the intro and the Rules section.

Actionability

Fully executable guidance: copy-paste commands ("git diff HEAD~1 --stat -- cmd/skillshare/ internal/", "python3 scripts/ai-context.py documentation", "docker exec \"$CONTAINER\" bash -c 'cd /workspace/website && npm run build'"), exact file-to-doc path mappings, and a testable validation rule ("Every `--flag` in docs must appear as a string literal in the command's source"). Specific examples cover the common cases.

Workflow Clarity

Seven clearly sequenced steps with explicit validation checkpoints (Step 2 compare-and-fix cross-validation, Step 6 build verification with "Confirm no broken links or build errors"). Below anchor 5 because no feedback loop is specified for build failure — what to do when npm run build reports broken links is left implicit.

Progressive Disclosure

Good structure with clearly signaled one-level-deep delegation of detail ("run `python3 scripts/ai-context.py documentation`. That topic is the source of truth for documentation ownership, code cross-validation and verification") and no bundle files to organize. Below anchor 5 because the ~40-line changed-file-to-doc-page mapping table is fully inlined in Step 1 rather than split into a reference file, making the body a workflow plus a large lookup table.

Specificity

Quotes "Update website docs to match recent code changes, cross-validating every flag against source", "document a new flag or command", "fix stale docs", and "update the README" — multiple concrete actions with comprehensive coverage of the doc-sync task. Matches anchor 5 rather than 4 because no meaningful action in this domain is missing.

Completeness

Explicitly answers both: what ("Update website docs to match recent code changes, cross-validating every flag against source") and when ("Use this skill whenever the user asks to: update documentation, sync docs with code, document a new flag or command, fix stale docs, or update the README" plus "If you just implemented a feature and need to update docs"). Matches the anchor-5 example pattern with concrete trigger phrases.

Trigger Term Quality

Natural phrases a user would actually say: "update documentation", "sync docs with code", "document a new flag or command", "fix stale docs", "update the README", with synonym coverage (docs/documentation, update/sync/document/fix). Not score 4 since no common natural variation for this domain is missing.

Distinctiveness Conflict Risk

Has a clear niche (website docs cross-validated against Go source; "Never manually edit website docs without cross-validating flags against Go source first"), but triggers like "update the README" and "document a new flag or command" carry minor overlap risk with a changelog/release-notes skill, and the CHANGELOG exclusion is only stated in the body, not the description. Mostly distinct with minor overlap risk rather than minimal, so anchor 4 fits better than 5.
