Upkeep is an audit skill from wei18, licensed MIT, that looks for drift across a whole repository: documentation that no longer matches code, specs out of step with the implementation, orphaned assets and broken conventions. It sends several focused reviewers in parallel and reports each finding with evidence and a severity, plus a self-contained HTML report. The README says it is output only and never edits or deletes files. It runs on a logged-in claude command line using a Pro or Max subscription, needs Node 20 and git, and clones its engine into a cache folder on first use. A reusable CI workflow can open a tracking issue. We would suggest it for repositories with many translated or hand-written docs. The limit is that findings come from language model reviewers, so they need a human read. The repository was last pushed on 6 November 2026, as read on 11 November. We have not run it ourselves.
