AgentLimits

AgentLimits

In Development

AgentLimits is a macOS Sonoma+ menu bar app with Notification Center widgets. It shows usage limits for ChatGPT Codex / Claude Code (5-hour + weekly, or monthly when the provider returns a monthly window), GitHub Copilot (monthly premium requests), and ccusage token usage. Custom usage scripts also let you track any other service's usage (e.g. Cursor, Google Antigravity) the same way — see Custom Usage Script Authoring.

What It Tracks
- Usage limits (Codex / Claude Code): 5-hour + weekly usage, or monthly usage when the provider returns a monthly window, via internal APIs.
  - If Codex temporarily returns only a weekly window, AgentLimits keeps the 5-hour slot unavailable and displays the returned value in the weekly slot.

  - Claude Code: https://claude.ai/api/organizations/{orgId}/usage
- Usage limits (GitHub Copilot): Monthly premium interaction quota via entitlement API.
  - Copilot: https://github.com/github-copilot/chat/entitlement
- Custom usage services: Run a user-selected executable that prints an AgentLimits JSON snapshot to stdout. Each service may provide one or two unique 5h, 1w, or 1month windows.
- Token usage (ccusage): daily/weekly/monthly tokens and cost via CLI.
