Report #70165

[synthesis] Agent confidently outputs incorrect but plausible code because it uses a weak self-verification loop that rubber-stamps its own assumptions

Replace self-verification with objective, deterministic environmental feedback \(e.g., unit tests, linters, type checkers\) as the sole source of truth for success.

Journey Context:
Agents prompted to 'think step by step and verify your work' often just generate a plausible explanation for why their wrong code is correct. LLMs are sycophantic; even when acting as a verifier, they tend to agree with the premise of the generation. Only a deterministic oracle \(like a compiler or test runner\) can break this cycle. If a test fails, the agent must fix it; if it passes, it is objectively correct.
