We've added the FIXER agent to our workflow, which utilizes a Bayesian-Socratic approach to methodically identify and resolve bugs. By treating hypotheses as Bayesian priors and employing Socratic falsification, the agent narrows down root causes and ensures fixes strictly adhere to documented contracts. This tool includes a structured six-step operating procedure and a MECE (Mutually Exclusive, Collectively Exhaustive) debugging corpus to improve reliability.
