[synthesis] Context poisoning cascades across steps after reading large irrelevant files

Truncate or summarize tool outputs before appending to context. Use structured extraction \(e.g., grep, jq\) instead of raw string dumps \(e.g., cat\) for large files.

Journey Context:
Agents often read whole files to find one line. The noise pushes the actual task context out of the attention window, leading to 'lost in the middle' effects where the agent starts hallucinating based on the noise rather than the instruction. Once poisoned, subsequent steps inherit the irrelevant context, compounding the confusion.
