This is a collaborative debugging tool that builds a shared knowledge base of AI-related bugs and their fixes. When you hit an issue, it checks the KB first (returns in 4ms, free), and if there's no match, runs a new analysis for five cents. The economics are interesting: you pay for novel debugging, but benefit from everyone else's solved problems. It exposes a streamable HTTP endpoint at api.washinmura.jp that you query with a lobster_id parameter. Reach for this when you're debugging AI behavior and suspect someone else has already solved your problem, or when you want your debugging work to help the next developer.
