You're getting a debugging knowledge base with nearly a thousand verified fixes baked in. The YanHui KB indexes previously solved errors so you can search against known issues instead of debugging the same problem twice. Reach for this when you're staring at an error message and suspect someone else has already solved it, or when you want Claude to check fixes against a corpus of working solutions. It runs over stdio and positions itself as institutional memory for debugging, turning one-off fixes into searchable, reusable knowledge. Most useful in teams or projects where the same classes of bugs keep surfacing.
