Overview

Detect drift, triage issues, and fix docs — from the terminal, your agent, or code.

Ships with everything you need to keep docs in sync with code:

Built on the TypeScript compiler API — accurate AST analysis, not regex heuristics
15 drift detection rules across structural, semantic, example, and prose categories
Example validation — type-checks and runs @example blocks in a sandbox
Coverage ratchet prevents documentation regression — coverage can only go up
First-class monorepo support with auto-detected workspaces and batch analysis
GitHub Action with PR comments, step summaries, and release gates
Scans external markdown docs for broken API references, stale tutorials, and outdated code examples
MIT licensed — CLI and SDK, fully open source
