javimosch 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
claudeshows "Missing API key", the user must log in manually first: open a terminal, runclaude, 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
- Launch
claudewith PTY - Wait for the welcome screen (poll until it appears)
- Send
/usage+ Enter - Read the output (poll until usage data appears)
- Close with Escape then
/exit - Report the results
Commands
# Launch claude with PTY
exec pty=true command="claude"
# Wait and check log
process action=poll sessionId=XXX timeout=5000
# Send /usage
process action=send-keys sessionId=XXX literal="/usage"
process action=send-keys sessionId=XXX keys=["Enter"]
# Read output
process action=poll sessionId=XXX timeout=5000
# Exit
process action=send-keys sessionId=XXX keys=["Escape"]
process action=send-keys sessionId=XXX literal="/exit"
process action=send-keys sessionId=XXX keys=["Enter"]
Notes
- If you see "Missing API key" → tell the user to log in; browser-based login won't work headlessly
- Allow a few seconds between polls — Claude CLI starts slowly
- "Current week" = weekly reset, not daily
Output Format
Report in a table:
| Usage | Resets | |
|---|---|---|
| Current session | X% used | today at HH:MM (timezone) |
| Weekly (all models) | X% used | HH:MM (timezone) |
| Weekly (Sonnet only) | X% used | HH:MM (timezone) |
| Extra usage | X% used / $X of $Y spent | date (timezone) |
Always show reset times. The CLI displays them as "Resets Xpm" — convert to HH:MM format.
