Conciseness

The body is lean and assumes Claude's competence: every step is a direct instruction with exact commands ('git log --oneline --no-merges --name-only <watermark>..HEAD', './test/docs/run_tests.sh validate') and no padding or explanation of concepts Claude already knows. It matches the 'every token earns its place' anchor.

Actionability

Guidance is fully executable: copy-paste-ready git commands for the watermark fallback, change gathering, and watermark write, plus the exact validation script path. Concrete edit patterns (insert rows, add sections, never edit fabro-api.yaml) cover the common cases, matching the anchor-5 example.

Workflow Clarity

Eight clearly sequenced steps with an early-exit checkpoint ('If nothing affects docs, tell the user and stop') and an explicit validation feedback loop ('run ./test/docs/run_tests.sh validate. Fix any failures before proceeding') before the watermark is written. It stays below anchor 5 because validation is conditional on DOT blocks only — non-DOT edits have no verification step, a minor validation gap for a batch editing workflow.

Progressive Disclosure

The body is a concise overview plus workflow, with the bulk mapping table correctly split into references/mapping.md (a real file, verified), clearly signaled with a linked bullet ('code-to-doc page mapping') and re-referenced at the point of use in step 3. References are one level deep and navigation is easy, matching the anchor-5 structure.

Specificity

The description lists several concrete actions — 'Reads git history since a watermark commit, maps changed files to doc pages, and makes surgical edits' — naming the mechanism, not just the domain. It falls short of anchor 5 only because ancillary capabilities (validation of examples, writing the watermark) are omitted, leaving minor coverage gaps.

Completeness

The 'what' is clear and concrete (update docs/public/ via git-history analysis, mapping, and surgical edits), but there is no 'Use when...' clause or equivalent explicit trigger guidance — 'based on recent code changes' only weakly implies when. Per the judging guidelines, a missing explicit trigger clause caps completeness at 3.

Trigger Term Quality

Natural terms users would say are present: 'Update documentation', 'docs', 'code changes', 'keep docs in sync with code'. A few common variations are missing (e.g., 'stale', 'outdated', 'out of date'), which keeps it below the comprehensive-synonym coverage of anchor 5 but above the sparse keyword coverage of anchor 3.

Distinctiveness Conflict Risk

The watermark-commit mechanism and 'surgical edits to keep docs in sync with code' carve out a distinct sync-docs-to-code niche with clear triggers. Minor overlap risk remains with general documentation-writing or commit-message skills, so it does not reach anchor 5's minimal conflict risk.
