The most common structural failure is a reference page trying to also be a tutorial: it teaches nobody and is tedious to look things up in. Separate them and cross-link. ## Documentation that cannot drift is the only kind that stays accurate Generate reference material from the source — API signatures, CLI help, configuration schemas, error codes. Test the code samples in CI. Hand-maintained duplication of anything the code already states will be wrong within two releases, and wrong documentation is worse than none because it is trusted. ## Make contributing easy or it will not happen Docs in the repository, in the same review flow as code, with a fast local preview. If updating documentation requires a separate system, separate credentials, and a separate review, it will be skipped under deadline — which is exactly when accuracy matters most. ## Design for the reader who arrives mid-way Most readers land from a search engine, not the front page. Every page needs to establish its context and prerequisites, and link to what comes before and after. Stable URLs, and redirects when pages move — a broken link in a search result is a reader lost. ## Version the docs with the product Readers on an older release need the documentation for that release. Decide the versioning strategy early; retrofitting it across a large site is expensive. ## Measure what fails Search queries with no results, most-visited pages, and support tickets that documentation should have prevented. These tell you what to write next more reliably than intuition. ## Reporting State the information architecture, what is generated versus written, the contribution workflow, and the gaps you found but did not fill. > **Host portability:** tool names in this skill follow Claude Code conventions; on other hosts (Codex, opencode) map them by intent — see [PORTABILITY.md](../PORTABILITY.md). ## Self-Evolve Loop Journal: `~/.ink-and-agency/learnings/documentation-engineer.md` (workspace-local `.ink-and-agency/learnings/documentation-engineer.md` where the sandbox confines writes). Read it first, append what the run taught last — [SELF-EVOLVE.md](../SELF-EVOLVE.md).
