Conciseness

The body is rule-dense with essentially no explanation of concepts Claude already knows — every line carries a house rule, ownership decision or command. It sits below anchor 5 because a few passages could be tightened: the run-on obligation-words sentence ("It also keeps obligation words (must, may, never), uncertainty and meaningful scope limits as strong as the source says…") and overlapping bullets in "Cover the feature's actual use" that restate "give each a clear home".

Actionability

Fully executable guidance throughout: copy-paste-ready commands ("pnpm --filter www build:source", "node tooling/scripts/check-plite-docs.mjs", "pnpm --filter www build:registry --check"), exact file paths ("content/docs/meta.json", "components/base/button.mdx"), and two decision tables keyed by changed contract and change type that cover the common edit cases.

Workflow Clarity

A clear sequence (handle request → read page/sibling/source → apply house style → select mechanics → verify) with an explicit validation checklist (the "Verify the changed claims" table), a feedback loop ("Run applicable checks once after the final prose pass. New source changes or a failure can require another pass"), and error-recovery guidance for red CI links at HEAD. This matches the anchor-5 pattern of checklist plus validate→fix→retry.

Progressive Disclosure

The "Select the needed mechanics" table routes each changed contract to one of four clearly signaled, one-level-deep reference files, and all four cited files (lanes.md, mdx.md, api-examples.md, plugin.md) exist in the bundle. It falls below anchor 5 because several other referenced paths — ../verify/SKILL.md, ../plate-ui/SKILL.md and the ../shadcn/apps/v4/content/docs/ corpus — do not resolve within this bundle, leaving navigation gaps.

Specificity

The description lists several concrete actions and scopes — "write or audit Plate public documentation, page design, examples, installation, MDX and navigation" plus "a one-line fix to existing advice, a Chinese twin or an embedded demo". It falls short of anchor 5 because everything is packed into one tangled sentence, which obscures the coverage and leaves minor gaps in how each area is served.

Completeness

Both halves are explicit: the when is "Use before any edit under content/docs, including a one-line fix to existing advice, a Chinese twin or an embedded demo" — a concrete trigger that anticipates edge cases — and the what is "to write or audit Plate public documentation, page design, examples, installation, MDX and navigation". The when-clause is already fully explicit and specific, so anchor 4's caveat ("'when' could be more explicit") does not apply.

Trigger Term Quality

Good coverage of natural terms a user would say when they need this skill: "edit under content/docs", "documentation", "examples", "installation", "MDX", "navigation", "audit". A few common variations ("docs page", "guide", "API reference") are missing, keeping it below the comprehensive synonym coverage of anchor 5.

Distinctiveness Conflict Risk

A clear niche ("Plate public documentation", edits under content/docs, Chinese twins, embedded demos) with triggers unlikely to fire for unrelated skills. It stays below anchor 5 because the description does not itself draw the boundary against the closely related `pstack:technical-writing` skill that the body delegates general prose to, leaving minor overlap risk on generic documentation requests.
