Pulled from the oven just right. Trustworthy, fact-dense, deeply satisfying.
Summary
Quibbler is a tool that critiques and corrects coding agents in real-time, running in the background to monitor AI coding assistants. It automatically intervenes when agents repeat mistakes or ignore specifications, learns rules from user interactions, and enforces those rules to prevent common errors. The tool helps prevent coding agents from making repetitive mistakes and maintains context across reviews.
