[agent\_craft] Agent triggers context compaction only when hitting the context limit, producing rushed low-quality summaries that miss critical details

Trigger compaction proactively at 70-80% context utilization, not at 95% or above. Prefer compaction at semantic boundaries—after a task completes, after a topic shift, after a debugging loop resolves—rather than at arbitrary token thresholds. Smaller, more frequent compactions at natural breakpoints produce dramatically better summaries than one large compaction under pressure.

Journey Context:
When you wait until 95%\+ context utilization to compact, you're forced to summarize a huge amount of context in a single pass. This is like trying to summarize a whole book in 5 minutes versus summarizing each chapter as you finish it—the chapter summaries will be far more accurate and useful. The non-obvious insight is that compaction quality is non-linear: it degrades sharply as the ratio of summarized-to-summary tokens increases. A 10:1 compression of 1000 tokens is manageable; a 10:1 compression of 10000 tokens loses critical detail. The semantic boundary trigger is equally important: summarizing mid-task \(halfway through debugging a function\) loses the thread of reasoning, while summarizing after the bug is fixed preserves the outcome and frees context for the next task. This is the agent equivalent of saving your work at chapter boundaries, not when the disk is full.
