Report #102598

[agent\_craft] Agent summarizing long context strips the exact detail needed for the bug

Use lossy compaction only on confirmed low-signal content. For high-signal content—error messages, stack traces, config values, type signatures, and user requirements—preserve verbatim or tag them as 'do not summarize.' Choose the compaction method based on what must survive: extractive for facts, abstractive for narrative, structured \(JSON\) for relationships.

Journey Context:
Summarization is seductive because it frees up window, but generic 'TL;DR' compression destroys the specific line number, exception message, or subtle config key that determines the fix. The common error is applying one summarizer to everything. A better pipeline classifies content first: stack traces and logs stay verbatim, chat history becomes bullet points, and broad documentation becomes a queryable index. If you must summarize, make the process reversible by keeping references \(file:line, doc URL\) so the agent can reload the original on demand. This mirrors MemGPT's archival-memory design: not all forgetting is equal.
