Report #57933

[agent\_craft] Context compaction and summarization drops critical variable names or exact IDs, causing subsequent steps to fail

When summarizing tool outputs or previous steps, use structured extraction \(e.g., JSON schema or specific key-value pairs\) for critical identifiers, rather than free-text summarization.

Journey Context:
Free-text LLM summarization is great for reducing tokens but terrible for preserving exactness. An agent might summarize a log output and change a specific error code or a file path slightly, breaking downstream tool calls. The tradeoff is that structured extraction is less flexible and might miss unexpected nuances. The right call is a hybrid approach: free-text summary for the 'what happened', but strict, verbatim extraction for parameters, IDs, and paths needed for future actions.
