[agent\_craft] After context compaction, exact error messages, stack traces, and variable names are lost—only vague summaries remain

Before any compaction, extract a 'facts sheet': exact error strings, key variable names, specific line numbers, API signatures, and constraint decisions. Keep this facts sheet verbatim \(not summarized\) in the working context. Only summarize the narrative around these facts.

Journey Context:
Naive summarization of conversation history preserves the 'what happened' but loses the 'exactly what was said.' For coding tasks, the exact error message string is often critical—you need to grep for it or match it against known patterns. A summary that says 'there was a TypeError' is nearly useless compared to 'TypeError: Cannot read properties of undefined \(reading "map"\) at UserList.tsx:42'. The MemGPT architecture addresses this by maintaining separate memory tiers: a working memory for exact currently-relevant facts and a recall memory for narrative summaries. The practical takeaway is to always separate facts \(preserved verbatim\) from narrative \(safe to summarize\) before any compaction event.
