Docs coverage

A skill for auditing whether a design system's documentation surface keeps pace with its components. It measures the code (the source of truth for what exists) against each documentation surface and reports three things: coverage gaps (components with no documentation), staleness (documentation that predates the component's last code change), and orphaned docs (pages for components that no longer exist). Produces a severity-rated finding table with per-signal confidence labelling.

Before you begin: verify references

Confirm that every path in this skill's frontmatter references: exists relative to this SKILL.md. If any is missing, stop: the install is incomplete, usually because a flattening installer (for example npx skills install) dropped the repo-root knowledge-notes/ directory. Tell the user to reinstall by a method in 1-INSTALL.md and run verify-install.sh from the install root. Proceed without the references only if the user explicitly says to, and then say in the output that it was produced without the pack's reference material.

Context

Code is the source of truth for what components exist; the documentation surface is measured against it. A component in code with no docs is a coverage gap; a page for a deleted component is an orphan; a page older than the component's last change is a staleness risk.

This skill is built to work with no integration at all: a components directory plus a Storybook build plus git history answer coverage and staleness for most teams. Hosted platforms (Zeroheight, Supernova, custom docs sites) are optional layers that light up when configured — never prerequisites. The audit never blocks on an integration; it logs what is unavailable and proceeds with what it can reach.

The hard part is trust. Coverage is a join between two lists — components in code and entries in the doc surface — and the join is only as reliable as the key that links them. Every coverage finding carries a confidence tier so a fuzzy guess is never presented as a fact. See documentation-coverage.md for the full model.
