Report #69669

[agent\_craft] Agent summarization step drops critical IDs, variable names, or exact error traces

When compacting context, enforce a structured output format \(e.g., JSON\) for the summary that explicitly preserves exact strings, IDs, and stack traces in dedicated fields, rather than free-text summarization.

Journey Context:
LLMs naturally summarize by generalizing, which strips out the exact tokens needed for subsequent tool calls \(like passing a specific run\_id or file\_path\). Free-text compaction loses these operational needles. Structured compaction forces the LLM to retain the exact data required for execution while still shedding the conversational verbosity.
