[agent\_craft] Agent hits context limit mid-task, forcing emergency truncation that drops critical recent context

Trigger compaction proactively at 60-70% of context capacity, not reactively at 95%\+. Maintain a priority-ordered 'must retain' list so compaction always knows what to protect. Reserve fixed token budgets for system prompt, working memory, and tool output zones.

Journey Context:
Reactive context management is a losing strategy. When you compact at 95% capacity, you're making rushed, low-quality decisions about what to drop under pressure — and you'll almost certainly lose something critical to the current subtask. Proactive compaction at 60-70% gives you the runway to be thoughtful: you can complete the current step, then compact with clear priorities. The budget reservation pattern \(X tokens for system, Y for working memory, Z for tool outputs\) prevents any single category from monopolizing context. This is directly analogous to memory management in operating systems: you don't wait until OOM to garbage-collect.
