Track overage spend

Sentinel detects overage from the rate-limit headers Anthropic returns, and can connect to claude.ai to track overage budget in detail.

1. Connect claude.ai. Open Settings → Overage spend tracking → Connect claude.ai and sign in inside the login window.

2. Set a spend cap. Configure a per-account or global overage budget cap. When an account’s spend crosses the cap, Sentinel pauses it until the next rolling-window reset; Auto mode routes around paused accounts.

3. Choose your notifications. In Settings → Notifications, enable OS notifications for overage transitions so you hear about them immediately.

Use email or Apple login in the Connect window

“Continue with Google” doesn’t work inside embedded webviews — Google blocks them. Use email / magic-link / Apple login in the Connect claude.ai window instead. If login fails, see Troubleshooting.

How detection works

Claude Code routes through the daemon, which inspects each response for anthropic-ratelimit-unified-overage-status: active and the matching reset header. A per-account state machine fires an event and a native OS notification when an account first enters overage — and the response is forwarded to Claude Code unchanged. See Alerts, overage & spend caps.
