Report #12670

[agent\_craft] Agent context window fills up with verbose tool outputs and historical steps, causing truncation or failure

Implement a rolling compaction strategy: once the context exceeds a threshold \(e.g., 70%\), summarize the oldest N turns into a single 'Session Summary' block, preserving tool names and key results but discarding raw outputs.

Journey Context:
Naive truncation drops recent, highly relevant context. Infinite context doesn't exist. Summarizing the \*entire\* history loses granularity. A rolling window with compaction of older turns preserves recent exact state while keeping the narrative thread of past actions, balancing token cost and recall.
