What problem does it solve? A repository that adopted the docs-quality rule set has rules on paper but no running verification, so nothing actually fails when documentation drifts. This Skill turns that rule set into an enforceable CI gate, wiring checks in cost order without turning every open pull request red on day one. ## Core Features & Use Cases - Declaration retrofit: Seeds and reviews doc_type and doc_tier comment declarations across the page tree using the correct comment carrier per generator (MkDocs, VitePress, mdBook, Docusaurus, Starlight, Sphinx). - Check wiring with a ratchet: Runs each check twice (error on the diff, warning on the whole tree), records warning baselines, and promotes checks to error only at zero standing violations. - Link and example verification: Configures strict builds or lychee for built output, a raw-markdown link pass, and a tested-example harness bound to pages by # doc: keys rather than mirrored paths. - Reader signals: Stands up zero-result search beacons, privacy-preserving analytics, time-to-first-working-result measurement, issue templates, and a Lighthouse score ratchet. - Use Case: A maintainer adopts a docs-quality rule set and asks to wire up docs CI; the Skill retrofits declarations, wires markdownlint and the shipped Python checks, proves each gate red once on a planted violation, and records the ratchet baselines. ## Quick Start Ask the assistant to wire up the docs-quality verification gate in this repository, starting with the doc_type declaration retrofit and the diff-scoped checks.
