Report #93853

[synthesis] Agent derails silently after reading large files or noisy tool outputs

Enforce strict output truncation and structured querying \(e.g., jq, grep\) over raw file reads, and inject a summary step before feeding tool output back into the context.

Journey Context:
Agents often call cat or read entire files to find a specific snippet. The massive output pushes the original task out of the context window or dilutes the attention mechanism, causing the agent to forget its goal and hallucinate. Simply increasing context size doesn't help because attention dilution still occurs. The tradeoff is between providing full context \(risking derailment\) and providing partial context \(risking missing info\). Structured queries and truncation force the agent to target its information retrieval, preserving the task context.
