# Claude Code Usage Check your Claude Code OAuth API usage limits for both session (5-hour) and weekly (7-day) windows. ## Quick Start ```bash cd {baseDir} ./scripts/claude-usage.sh ``` ## Usage ```bash # Default: show cached usage (if fresh) ./scripts/claude-usage.sh # Force refresh from API ./scripts/claude-usage.sh --fresh # JSON output ./scripts/claude-usage.sh --json # Custom cache TTL ./scripts/claude-usage.sh --cache-ttl 300 ``` ## Output **Text format** (default): ``` 🦞 Claude Code Usage ⏱️ Session (5h): 🟢 ████░░░░░░ 40% Resets in: 2h 15m 📅 Weekly (7d): 🟡 ██████░░░░ 60% Resets in: 3d 8h ``` **JSON format** (`--json`): ```json { "session": { "utilization": 40, "resets_in": "2h 15m", "resets_at": "2026-01-19T22:15:00Z" }, "weekly": { "utilization": 60, "resets_in": "3d 8h", "resets_at": "2026-01-22T04:00:00Z" }, "cached_at": "2026-01-19T20:00:00Z" } ``` ## Features - 📊 **Session limit** (5-hour window) - Short-term rate limit - 📅 **Weekly limit** (7-day window) - Long-term rate limit - ⚡ **Smart caching** - 60-second cache to avoid API spam - 🎨 **Beautiful output** - Progress bars, emojis, color-coded status - 🔄 **Force refresh** - `--fresh` flag to bypass cache - 📤 **JSON output** - Machine-readable format - 🔔 **Automated monitoring** - Get notified when quotas reset ## Status Indicators - 🟢 **Green** - 0-50% usage (healthy) - 🟡 **Yellow** - 51-80% usage (moderate) - 🔴 **Red** - 81-100% usage (high/critical) ## Requirements - **macOS**: Uses Keychain to access Claude Code credentials - **Linux**: Uses `secret-tool` for credential storage - **Credentials**: Must have Claude Code CLI authenticated ## How It Works 1. Retrieves OAuth token from system keychain 2. Queries `api.anthropic.com/api/oauth/usage` with OAuth bearer token 3. Parses `five_hour` and `seven_day` utilization metrics 4. Calculates time remaining until reset 5. Formats output with progress bars and status indicators 6. Caches result for 60 seconds (configurable) ## Cache Default cache: `/tmp/claude-usage-cache` (60s TTL) Override: ```bash CACHE_FILE=/tmp/my-cache CACHE_TTL=300 ./scripts/claude-usage.sh ``` ## Examples **Check usage before starting work:** ```bash ./scripts/claude-usage.sh --fresh ``` **Integrate with statusline:** ```bash usage=$(./scripts/claude-usage.sh | grep "Session" | awk '{print $NF}') echo "Session: $usage" ``` **Get JSON for monitoring:** ```bash ./scripts/claude-usage.sh --json | jq '.session.utilization' ``` ## Automated Monitoring ### Session Refresh Reminders (Recommended) Get notified exactly when your 5-hour session quota refreshes! **Quick Setup:** ```bash ./scripts/session-reminder.sh ``` This creates a **self-scheduling chain** of cron jobs that: 1. Checks your current session expiry time 2. Schedules the next reminder for when your session refreshes 3. Notifies you with current usage stats 4. Auto-removes itself (the new cron takes over) **What You'll Get:** ``` 🔄 Claude Code Session Status ⏱️ Current usage: 44% ⏰ Next refresh: 2h 15m Your 5-hour quota will reset soon! 🦞 ✅ Next reminder scheduled for: Jan 22 at 01:22 AM ``` **How It Works:** - Each reminder runs `claude-usage.sh` to find the exact session reset time - Schedules a one-time cron for that exact moment - Repeats every 5 hours automatically - Self-correcting if session times ever drift **Benefits:** - ✅ Accurate to the minute - ✅ No manual scheduling needed - ✅ Adapts to your actual usage patterns - ✅ Minimal API calls (only when needed) ### Reset Detection Monitor (Alternative) Get automatic notifications when your Claude Code quotas reset by polling usage. **Quick Setup:** ```bash # Test once ./scripts/monitor-usage.sh # Setup automated monitoring (runs every 30 minutes) ./scripts/setup-monitoring.sh ``` Or add via ThinkFleetBot directly: ```bash # Check every 30 minutes thinkfleetbot cron add --cron "*/30 * * * *" \ --message "cd /Users/ali/thinkfleet/skills/claude-code-usage && ./scripts/monitor-usage.sh" \ --name "Claude Code Usage Monitor" \ --session isolated --deliver --channel telegram ``` **What You'll Get:** ``` 🎉 Claude Code Session Reset! ⏱️ Your 5-hour quota has reset 📊 Usage: 2% ⏰ Next reset: 4h 58m Fresh usage available! 🦞 ``` **How It Works:** 1. **Monitors usage** every 30 minutes (configurable) 2. **Detects resets** when usage drops significantly (>10% or <5%) 3. **Sends notifications** via Telegram when resets occur 4. **Tracks state** in `/tmp/claude-usage-state.json` **Customization:** ```bash # Change check interval thinkfleetbot cron add --cron "*/15 * * * *" ... # Every 15 minutes thinkfleetbot cron add --cron "0 * * * *" ... # Every hour # Custom state file location STATE_FILE=/path/to/state.json ./scripts/monitor-usage.sh ``` ### Which Monitoring Method? | Feature | Session Reminder | Reset Detection | |---------|-----------------|-----------------| | Accuracy | ✅ Exact minute | ~30min window | | API calls | Minimal | Every check | | Notification timing | Right on reset | Up to 30min delay | | Setup | One command | One command | | Maintenance | Self-scheduling | Cron runs forever | **Recommendation:** Use **Session Reminder** for precise, real-time notifications. ## Troubleshooting **No credentials found:** - Ensure Claude Code CLI is installed and authenticated - Run `claude` once to trigger OAuth flow **API request failed:** - Check internet connection - Verify OAuth token hasn't expired - Try `--fresh` to force new request **Linux users:** Install `libsecret` for credential storage: ```bash # Debian/Ubuntu sudo apt install libsecret-tools # Fedora/RHEL sudo dnf install libsecret ```
