Token Usage Optimizer

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

(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

API Endpoint

GET https://api.anthropic.com/api/oauth/usage
Authorization: Bearer <access-token>
anthropic-beta: oauth-2025-04-20

Response:

{
  "five_hour": {
    "utilization": 22.0,
    "resets_at": "2026-02-20T14:00:00.364238+00:00"
  },
  "seven_day": {
    "utilization": 49.0,
    "resets_at": "2026-02-24T10:00:01.364256+00:00"
  }
}

Requirements

• curl — API requests
• date — Timestamp parsing
• grep, 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
