Conciseness

The body is lean throughout: a pattern table instead of prose, a copy-paste template, terse PR-review bullets, and two one-line commands. No concepts Claude already knows are explained (no "what is a README" padding), and every section adds non-obvious guidance — matching anchor 5 ("every token earns its place") rather than 4, which reserves room for trimmable over-explanation that isn't present here.

Actionability

The documentation-shape template is copy-paste ready with concrete placeholders, the pattern table gives specific rules ("Put the decision, action, or outcome first"), and the Commands section has executable git/gh commands. As an instruction-only skill per the scoring notes, the absence of program code is not penalized; this matches anchor 5 ("copy-paste ready... covers the common cases") rather than 4, which implies minor gaps in the concrete guidance.

Workflow Clarity

The template imposes a clear sequence (title → quick path → details → checklist → next step) and the template's Checklist section serves as a verification checkpoint, with the git/gh commands offering a way to inspect scope. It is not 5 because there is no explicit process for applying the patterns to an existing dense doc (no ordered steps like "read → identify the answer → restructure → verify scannability"), leaving a minor gap; it is above 3 because sequence and a checkpoint mechanism are present.

Progressive Disclosure

This is a single-file skill with no bundle directories; the ~72-line body is appropriately all-inline, split into six clearly headed sections that are easy to navigate, with no content that belongs in a separate reference file. It matches the guideline that a compact, well-organized, single-purpose skill with no external references scores 5 — and it avoids anchor 4's 'minor organization gaps' since section boundaries are clean and nothing is buried.

Specificity

The description names the domain ("Design docs") but the only action stated — "reduce cognitive load" — is an abstract goal, not a concrete action like "extract", "fill", or "merge". It matches anchor 2 ("Names the domain but actions are minimal or generic") rather than 3, which requires 1-2 concrete actions, and not 1, since the domain and an outcome are explicitly named.

Completeness

Both parts are present: "Design docs that reduce cognitive load" states the what, and "Trigger: writing guides, READMEs, RFCs..." is an explicit when clause. It is not anchor 5 because the 'what' is a single vague capability rather than the multiple concrete actions in the anchor-5 example ("Extract text and tables from PDF files, fill forms, merge documents"), and it is clearly above anchor 3's missing/weak 'when'.

Trigger Term Quality

"guides, READMEs, RFCs, onboarding, architecture, or review-facing docs" gives good natural keyword coverage, including concrete artifact names users would say. It falls short of anchor 5's comprehensive synonym coverage: common variations like "documentation", "PR descriptions", "review comments", or ".md files" are missing, so it sits at anchor 4 ("Good keyword coverage; a few natural terms missing") rather than 5, but well above 3's partial coverage.

Distinctiveness Conflict Risk

The doc-design niche (RFCs, READMEs, review-facing docs) is somewhat specific, but "guides", "architecture", and "onboarding" overlap heavily with generic writing and documentation skills, matching anchor 3 ("Somewhat specific but could still overlap with similar skills"). Not 4, because the trigger set is broad enough that several writing/editing skills could plausibly claim the same request; not 2, because the cognitive-load framing and RFC/review-facing terms do carve out a recognizable niche.
