Report #100426

[synthesis] An agent validates its own wrong assumptions by using a tool whose output it misinterprets, creating a reinforcing error loop

Separate the actor that generates a claim from the validator that checks it. Use deterministic checks—diffs, test suites, schema—before LLM-based verification, and require the validator to quote source IDs or line numbers, not paraphrase.

Journey Context:
When the same model writes code and then reviews it, it often 'confirms' its own earlier interpretation because the prior reasoning weights are still in context. This is analogous to confirmation bias. The fix is an independent critic with access to raw tool outputs such as git diff and test logs and a mandate to cite evidence. Code-review benchmarks show reviewer models must be presented with the original artifact, not a summary, to catch subtle errors.
