Claude Code Usage

Check your Claude Code OAuth API usage limits for both session (5-hour) and weekly (7-day) windows.

Quick Start

cd {baseDir}
./scripts/claude-usage.sh

Usage

# 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):

{
  "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:

CACHE_FILE=/tmp/my-cache CACHE_TTL=300 ./scripts/claude-usage.sh

Examples

Check usage before starting work:

./scripts/claude-usage.sh --fresh

Integrate with statusline:

usage=$(./scripts/claude-usage.sh | grep "Session" | awk '{print $NF}')
echo "Session: $usage"

Get JSON for monitoring:

./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:

./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:

# Test once
./scripts/monitor-usage.sh

# Setup automated monitoring (runs every 30 minutes)
./scripts/setup-monitoring.sh

Or add via Clawdbot directly:

# Check every 30 minutes
clawdbot cron add --cron "*/30 * * * *" \
  --message "cd /Users/ali/clawd/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:

# Change check interval
clawdbot cron add --cron "*/15 * * * *" ...  # Every 15 minutes
clawdbot cron add --cron "0 * * * *" ...      # Every hour

# Custom state file location
STATE_FILE=/path/to/state.json ./scripts/monitor-usage.sh

Which Monitoring Method?

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:

# Debian/Ubuntu
sudo apt install libsecret-tools

# Fedora/RHEL
sudo dnf install libsecret
