Claude Usage Checker

Launches the Claude CLI interactively (PTY) and reads the /usage output to report your Claude Code / Claude Max quota.

Prerequisites

• Claude CLI must be installed (npm i -g @anthropic-ai/claude-code) and logged in
• If running claude shows "Missing API key", the user must log in manually first: open a terminal, run claude, and complete the browser login flow
• Requires an interactive PTY — the agent will launch a local process and read its output (quota info only)

Steps

1. Launch claude with PTY
2. Wait for the welcome screen (poll until it appears)
3. Send /usage + Enter
4. Read the output (poll until usage data appears)
5. Close with Escape then /exit
6. Report the results
