# Skill: Context Management > "Context is RAM. Filesystem is external memory—unlimited, persistent, operable." — Manus ## When Before context becomes a constraint. The kernel monitors automatically. ## The Thresholds | Usage | Action | Why | |-------|--------|-----| | 60% | Run `/compact` | Prevent drift before it starts | | 80% | Delegate to sub-agent | Preserve parent for orchestration | | 90% | Emergency compress | Summarize aggressively | ## The Protocol 1. **At 60%**: Compact. Preserve: objective, ADRs, failures. 2. **At 80%**: Spawn sub-agent for current task. Parent orchestrates. 3. **Always**: Write to files, not context. Files survive. Context doesn't. ## The Key Insight > **Compaction is continuation, not termination.** Auto-compaction enables infinite work. Your objective survives if you keep `working.md` current — the system loads it on resume. Don't wrap up early to "fit" in context. Don't cut corners. Let compaction happen. Work continues on the other side. ## The Anti-Patterns | Don't | Do | Why | |-------------------|---------------------------|----------------------------------| | Hoard context | Write to files | Files are unlimited | | Wait until 90% | Compact at 60% | Late compaction loses objectives | | Orphan sub-agents | Handoff before delegating | Context must transfer | | Wrap up early | Trust the system | Compa
