Security notice: This widget reads sessionKey from your browser's local cookie storage (cookies.sqlite) to authenticate with claude.ai. The key is only sent to claude.ai — no third parties. It is stored in plaintext in ~/.claude_usage_yasb.json on your local machine. Do not use on shared or untrusted computers.

YASB Setup

1. Add widget to config.yaml

widgets:
  claude-usage:
    type: "yasb.custom.CustomWidget"
    options:
      label: "{data}"
      label_alt: "{data}"
      class_name: "claude-usage-widget"
      exec_options:
        run_cmd: "claude-usage-yasb"
        run_interval: 60000
        return_format: "string"

2. Add to bar layout

center: ["claude-usage"]

3. Open claude.ai in your browser

That's it — the widget reads cookies automatically from Firefox or Chrome. No manual configuration needed.

How it works

1. Reads sessionKey and org_id from Firefox/Chrome cookies
2. Calls claude.ai/api/organizations/{org_id}/usage
3. Displays session % with reset timer and weekly %

Supported browsers: Firefox, Chrome, Edge, Brave

Cookie refresh is automatic — as long as you're logged in to claude.ai in your browser.
