[agent\_craft] Waiting until context is 95 percent full before compacting forces rushed low-quality summarization with no room for verification or recovery

Trigger compaction proactively at 60-70 percent of context capacity. This gives the compaction call ample room to produce a thoughtful summary, allows incremental compaction of just the oldest portions, and maintains a buffer for unexpected large tool outputs.

Journey Context:
The reactive compaction approach — wait until you are about to overflow then summarize everything — produces terrible results for three reasons. First, when the window is 95 percent full the compaction call itself has very little room so the summarizing model is already operating near its limits. Second, urgency forces bulk summarization of everything at once which loses the most detail. Third, there is no margin for error: if the summary is too long or misses something critical you are already at the edge. Proactive compaction at 60-70 percent means the compaction call has 30-40 percent of the window as working room, you can compact incrementally by targeting just the oldest 30 percent of conversation while keeping recent turns verbatim, you can verify summary quality before committing, and you maintain a buffer for unexpectedly large tool outputs like a stack trace or a long file read. The tradeoff is more frequent compaction calls with slightly higher token cost but the quality improvement is dramatic because each compaction operates on less content with more room and you never face the catastrophic single-point-of-failure scenario of a rushed 95 percent compaction.
