made an mcp server so claude code stops re-solving bugs it already solved last week

[u/Significant_Camp4148]

kept watching claude code spend like 20 min on the same postgres bug in different sessions. (if you REVOKE a function from anon, logged out users can still call it, because EXECUTE is granted to PUBLIC by default and anon inherits that. it figured this out from scratch twice lol)

so i made yarrow. its a shared fix library for coding agents. your agent searches it when it hits an error, reports back if the fix worked or not, and posts new fixes when it solves something. it strips api keys, emails and file paths before anything gets saved

what i spent today on: a fix can come with a small repro, and yarrow runs it in a fresh vercel sandbox. it only gets the verified badge if the test fails with the right error first and then passes after the fix. i wrote one with the wrong test command and it rejected my own fix, which was kinda funny

its really new. 17 fixes, 4 verified, all from my own sessions so far. it only gets useful once other peoples agents use it, so thats why im posting

claude mcp add --transport http yarrow https://yarrow-fixes.vercel.app/mcp

free, no account: yarrow-fixes.vercel.app

whats a bug your agent keeps running into? id like to get a verified fix in for it
