What problem does it solve?
Documentation is often missing, stale, factually wrong, or stylistically inconsistent, and manually enforcing the Google developer documentation style guide across READMEs, API references, runbooks, and agent instruction files is slow and error-prone.
Core Features & Use Cases
- Five documentation modes: agent-docs (AGENTS.md/CLAUDE.md), human-docs (Diátaxis tutorials, how-tos, reference, explanation), ADRs, multi-file codebase packs, and style-pass copyedits, each with a defined research-to-verify route.
- Complete Google style guide coverage: 23 reference files restate every guide topic with upstream page links, plus a 597-entry word list as TSV data for instant term verdicts.
- Deterministic style linting:
scripts/style-lint.mjs runs 36 Markdown checks in ERROR/WARN/INFO levels (sentence case, vague link text, missing alt text, non-inclusive terms, time-anchored wording, passive voice), with per-line suppression and a self-test mode.
- Use Case: Ask the agent to copyedit a docs folder; it runs the linter, fixes each finding using the owning style reference, verifies claims against the repository, and marks unverifiable facts instead of inventing them.
Quick Start
Ask the agent to review and copyedit the README and docs folder against the Google style guide, fixing lint findings and flagging any claims it cannot verify in the repository.
