[architecture] Output drift and hallucinated tool arguments when relying solely on the generating agent for self-verification

Implement a separate, isolated LLM-as-a-judge verifier agent or deterministic assertions \(e.g., Python unit tests\) at the handoff boundary before passing data to the next agent.

Journey Context:
Developers often prompt an agent to 'check your work' before responding. This is highly unreliable because the agent suffers from the same logical blind spots during verification as it did during generation. To truly verify an agent's output, you need an independent evaluator. Deterministic checks \(regex, schema validation, code execution\) are best for syntax and facts; a separate LLM with a stricter, focused rubric is best for semantic correctness. This adds latency and cost, but prevents garbage-in-garbage-out cascading failures.
