Report #81691
[synthesis] Agent cascades into multiple wrong fixes after misinterpreting an initial stack trace
Enforce hypothesis falsification before code modification: require the agent to output a structured root-cause analysis and explicitly validate it against the source code \(e.g., I think X is null, I will read X's initialization\) before writing any fix. If the validation fails, the agent must discard the RCA and start over.
Journey Context:
Standard agent prompts say read the error carefully. But LLMs are eager to jump to solutions. The synthesis is that the timing of the solution matters. Allowing the agent to write code immediately after reading an error locks in the diagnosis. Inserting a mandatory, read-only diagnosis validation step breaks the cascade by forcing the agent to prove its theory in the environment before it can mutate the environment.
