# Context Optimizer
Manage your context window and token budget effectively.
## Quick Diagnosis
1. Run `/context` to check current usage
2. If > 70% โ compact now before it degrades
3. If > 90% โ 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
Flowy AI Flows that just work. Hand-picked Claude Code plugins that fire the right skill as you prompt.
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 โ subagent
- Large file exploration โ subagent
- Documentation generation โ subagent
- Log analysis โ subagent
The main session stays clean while subagents handle the volume.
## Context Budget Planning
| Phase | Target Usage | Action If Over |
|-------|-------------|----------------|
| Planning | < 20% | Keep plans concise |
| Implementation | < 60% | Compact between files |
| Testing | < 80% | Delegate to subagent |
| Review | < 90% | Start fresh session |
## Token Efficiency
### Output Reduction (40-60% savings)
- No sycophantic openers ("Sure!", "Great question!")
- No closing fluff ("Let me know if you need anything!")
- No prompt restatement before answering
- Code first, explanation only if non-obvious
- Structured output (tables, bullets) over prose
- ASCII only: -- not em dashes, straight quotes not smart quotes
### Behavioral Efficiency
- One-pass coding: complete solution, test once, stop if green
- Read before write: never modify unread files
- No re-reads: don't re-read unchanged files
- Tool-call budgets: 20 (quick fix) to 80 (large feature)
- Never iterate more than twice on the same failure
### Task Profiles
Switch response style based on context:
- **Coding**: code first, minimal explanation, simplest solution
- **Agent/Pipeline**: structured output only, no prose, parseable
- **Analysis**: finding first, tables over paragraphs, sourced numbers
## CLAUDE.md Optimization
- Root CLAUDE.md: < 60 lines ideal, < 150 max
- Move package-specific info to package-level CLAUDE.md
- Move personal preferences to CLAUDE.local.md
- Remove obvious or rapidly-changing information
## When Context Is Degraded
Signs:
- Claude repeats itself or forgets earlier context
- Responses become generic or lose project-specific knowledge
- Tool calls start failing for reasons that worked earlier
Fix:
1. Manual `/compact`
2. If still bad: new session with `/resume`
3. For recurring issues: reduce CLAUDE.md size, disable MCPs
