[synthesis] Agent generates confident explanations for wrong tool outputs treating them as ground truth

Mandate intermediate validation prompts that require the model to explicitly state confidence in tool outputs before proceeding, using a structured uncertainty scale

Journey Context:
Current patterns treat tool results as immutable facts within the reasoning trace, creating a compounding error cascade when APIs return partial matches, stale data, or malformed JSON that the LLM interprets creatively. The ReAct pattern and similar frameworks separate Thought/Action/Observation into discrete steps, but fail to include an explicit 'Verification' phase where the model assesses observation reliability. Without this, the agent confuses 'the tool returned X' with 'X is true and complete,' leading to justification chains that sound logical but rest on faulty premises. The fix introduces a forced calibration step that breaks the automatic flow, requiring explicit uncertainty quantification that downstream steps can check.
