Token Usage Optimizer
Version: 1.0.5
Get the most out of your Claude Code subscription by monitoring usage in real-time and optimizing your daily burn rate.
Why Use This?
You're paying $20-200/month for Claude Code. Are you:
- ✅ Using it to its full potential?
- ❌ Hitting limits too early?
- ❌ Leaving quota unused at reset?
This skill tracks your 5-hour session and 7-day weekly quotas, calculates your daily burn rate, and tells you if you should use more or throttle back.
Features
- 📊 Burn Rate Tracking — Are you under/over/on-pace for optimal usage?
- ⚡ Smart Alerts — One-time warnings when SESSION > 50% (no spam)
- 🎯 Plan-Aware — Auto-detects Pro ($20), Max 100 ($100), Max 200 ($200)
- 💾 Ultra-Lightweight — 10-minute cache, minimal API calls
- 📅 Daily Reports — Evening summary: SESSION, WEEKLY, burn rate
- 🔄 Token Health Check — Hourly check + alert if manual refresh needed (~once per week)
Quick Start
1. Setup
Run the setup wizard to configure your OAuth tokens:
cd {baseDir}
./scripts/setup.sh
You'll need:
- Access Token (
sk-ant-oat01-...) - Refresh Token (
sk-ant-ort01-...)
See references/token-extraction.md for how to get these.
2. Check Usage
./scripts/check-usage.sh
Output:
SESSION=22.0
WEEKLY=49.0
BURN_RATE=OK
CACHED_AT=1771583780
3. Human-Readable Report
./scripts/report.sh
Output:
📊 Claude Code Daily Check:
⏱️ SESSION (5h): 22%
📅 WEEKLY (7d): 49%
⚪ На темпі — оптимальне використання
Burn Rate Interpretation
- 🟢 UNDER — You're under-using your subscription. Use more to get your money's worth!
- ⚪ OK — On pace. Optimal usage for your plan.
- 🔴 OVER — Over-burning. You'll hit limits before reset.
Daily Budget by Plan
| Plan | Monthly | Weekly Budget | Daily Budget |
|---|---|---|---|
| Pro | $20 | ~14% | ~2% |
| Max 100 | $100 | ~14% | ~2% |
| Max 200 | $200 | ~14% | ~2% |
(7-day window resets weekly, so ~14% per day = 100% per week)
Integration with Heartbeat
Add to your HEARTBEAT.md:
### Evening Check (18:00-20:00)
- Claude Code usage: `/path/to/token-usage-optimizer/scripts/report.sh`
Alert Thresholds
- SESSION > 50% → 🟡 One-time warning (won't repeat until next reset)
- WEEKLY > 80% → 🟡 One-time warning
Alerts use state tracking (/tmp/claude-usage-alert-state) to avoid spam.
Cache
Default: /tmp/claude-usage.cache with 10-minute TTL.
Override:
CACHE_FILE=/custom/path CACHE_TTL=300 ./scripts/check-usage.sh

Requirements
curl— API requestsdate— Timestamp parsinggrep,cut,printf— Text parsing
No external dependencies (jq, etc.).
Privacy
Tokens are stored in {baseDir}/.tokens (gitignored).
Never share your access/refresh tokens.
Token Health Check (Recommended)
OAuth tokens work for ~1 week, then need manual refresh. Set up 30-minute health check for better reliability:
# Add cron job to check token health every 30 minutes
openclaw cron add \
--name "claude-token-refresh" \
--every 30m \
--announce \
--message "Запусти {baseDir}/scripts/auto-refresh-cron.sh"
What it does:
- ✅ Token valid → silent (no spam)
- 🔴 Token expired → one-time alert with manual refresh instructions
Manual refresh (once per week, 30 seconds):
claude auth login
# Browser opens → sign in to claude.ai → done!
Tokens auto-sync to {baseDir}/.tokens after successful login.
Troubleshooting
"No token configured"
→ Run ./scripts/setup.sh
"Token expired" / "API request failed"
→ OAuth tokens expire after ~1 week
→ Manual refresh: claude auth login (browser opens → sign in → done)
→ Set up hourly health check to get alerts before expiry (see above)
Burn rate shows empty
→ API response missing resets_at — try again in a few minutes
Auto-refresh failed
→ OAuth refresh endpoint may have changed
→ Manual refresh: claude auth login → copy new tokens → run ./scripts/setup.sh
