- Optimize token usage and context management. Use when sessions feel slow, context is degraded, or you're running out of budget.
Context Optimizer
Manage your context window and token budget effectively.
Quick Diagnosis
- Run
/contextto check current usage - If > 70% → compact now before it degrades
- 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:
{
"env": {
"CLAUDE_AUTOCOMPACT_PCT_OVERRIDE": "50"
}
}
MCP Audit
Keep <10 MCPs enabled, <80 tools total. Each MCP adds overhead to every request.
/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 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:
- Manual
/compact - If still bad: new session with
/resume - For recurring issues: reduce CLAUDE.md size, disable MCPs

VerifiedTrustedCommunity
SkillOpt-flavored offline training loop for any SKILL.md. Treats accumulated learn-rule corrections as training trajectories, proposes bounded patches via an optimizer LLM, gates each candidate against a held-out validation set built from the user's own past corrections, and ships only candidates that demonstrably improve the score. Inspired by Microsoft SkillOpt's ReflACT pipeline (rollout → reflect → aggregate → select → update → evaluate) adapted to pro-workflow's SQLite store. Use when a skill has accumulated 8+ learn-rule rows and the user wants the skill itself to get better, not just longer.
