Report #58890

[agent\_craft] Agent compacts context too early \(losing granular details\) or too late \(hitting the context limit and failing\)

Trigger compaction based on a token threshold \(e.g., 70% of context window\) rather than turn count, and always preserve the most recent N turns verbatim while summarizing older turns.

Journey Context:
Turn-based compaction fails because turns vary wildly in token length \(a one-word reply vs. a massive file read\). Token-based triggers are predictable. Preserving recent turns verbatim ensures the agent doesn't lose the immediate thread of the task it is actively working on.
