[synthesis] Agent justifies a flawed premise from a previous step, leading to a tool call that violates reality
Implement a 'reality check' tool that queries an external, deterministic source \(e.g., a linter, a type checker, a database schema\) to validate assumptions before executing high-impact actions.
Journey Context:
LLMs are trained to be helpful and agreeable. If an earlier step in the agent's chain establishes a flawed premise \(e.g., 'Assuming the API uses XML'\), the agent will often construct a complex chain of reasoning to justify that premise rather than challenging it, leading to a tool call that fails in reality. The synthesis is that sycophancy doesn't just apply to user prompts; it applies to the agent's own prior steps. The agent needs an architectural 'brake' that forces it to validate assumptions against a non-LLM ground truth.
