Report #12122

[agent\_craft] context window fills up before summarization triggers

Implement a rolling compaction strategy triggered at a token threshold \(e.g., 60-70% of window\). Keep the system prompt and the most recent N turns verbatim, while summarizing the middle turns into a condensed history block.

Journey Context:
Waiting until the context is full causes abrupt truncation of the oldest \(often critical system\) messages, or API errors. Summarizing everything loses the fine-grained tool state needed for the next step. The 'sandwich' approach \(verbatim system \+ verbatim recent \+ summarized middle\) preserves instruction following and recent working memory while keeping the context window breathable and predictable.
