# Wellworn The judgment layer for coding agents. It answers which stack, library, skill, or design system to use, what breaks at which version, and who verified it. Every answer names a reviewer, the version tested, the sources, and the date it has to be checked again. Corpus right now: verdicts served 25, flagged for recheck 0, traps 58, catalog tools 28242. ## Install claude mcp add --transport http wellworn https://mcp.wellworn.dev/mcp Works without a key at 60 calls a day per IP.
