# Context Optimizer Manage your context window and token budget effectively. ## Quick Diagnosis 1. Run `/context` to check current usage 2. If > 70% → compact now before it degrades 3. If > 90% → you're in the "dumb zone", compact immediately ## Optimization Strategies ### Immediate | Action | Saves | When | |--------|-------|------| | `/compact` | 30-50% context | At task boundaries | | Disable unused MCPs | ~5% per MCP | When switching domains | | Use subagents for exploration | Keeps main context clean | Heavy search/read tasks | | Fresh session via `/resume` | 100% reset | When starting unrelated work | ### Configuration Set proactive auto-compaction: ```json { "env": { "CLAUDE_AUTOCOMPACT_PCT_OVERRIDE": "50" } } ``` ### MCP Audit Keep <10 MCPs enabled, <80 tools total. Each MCP adds overhead to every request. ```bash /mcp # List active servers # Disable what you're not using ``` ### Prompt Engineering for Token Efficiency - Scope your prompts: "In src/auth/, fix the login bug" - Provide constraints: "Don't modify the middleware" - Give acceptance criteria: "Should return 429 after 5 attempts" - Avoid vague prompts: "Fix the code" (forces Claude to read everything) ### Subagent Delegation Heavy operations that generate lots of output should go to subagents: - Test suite output → subagent - Large file exploration → subagent - Documentation generation → subagent - Log analysis → subagent The main session stays clean while subagents handle t
