[synthesis] Agent validates its own wrong assumptions using a flawed self-generated validator

Decouple generation and validation; use a separate, isolated LLM call or a deterministic external tool \(like a linter or compiler\) for validation, never the agent's own self-reflection on the same context.

Journey Context:
If an agent writes a regex or validation function that is subtly wrong \(e.g., too permissive\), it will use this broken validator to check its own subsequent outputs. The agent receives a pass signal and confidently proceeds, reinforcing its flawed logic. Self-reflection is unreliable because the agent's internal logic is already skewed. The tradeoff is the cost of an extra tool call, but deterministic or isolated validation breaks the confirmation bias loop.
