Know when your AI coding agent is done, without watching the terminal

The problem with long agent runs

You send Claude Code a task, switch to another window, and then spend the next ten minutes wondering whether it has finished, is waiting for permission, or got stuck. Notification sounds are easy to miss and system notifications are easy to dismiss. A small animated character in the corner of your screen is hard to miss, and pleasant to look at.

What Capybara Pet does while an agent works

• Busy: when you send a prompt, he pulls out a phone, furrows his brow and sweats while the agent works.
• Done: when the agent finishes, he does a happy hop with sparkles and a squeak.
• Needs you: when Claude Code asks for permission or input, he hops too, so you know it is waiting for you.
• Typing wins: if you start typing, he swaps the phone for his keyboard, then goes back to the phone.

Set up Claude Code in one click

Right-click the capybara (or open the menu bar or tray icon) and choose Connect Claude Code. Capybara Pet adds the required hooks to ~/.claude/settings.json, saves a backup next to it and leaves your other settings untouched. Start a new Claude Code session afterwards, because hooks are read when a session starts.

Works with other agents too

Capybara Pet listens on a local address that never leaves your computer: http://127.0.0.1:47831. Anything that can run a shell command or send an HTTP request when it starts and finishes can drive him, including Codex CLI, Cursor, Aider, Gemini CLI and your own scripts.

curl http://127.0.0.1:47831/event/thinking   # busy: phone out, sweating
curl http://127.0.0.1:47831/event/done       # happy hop
curl http://127.0.0.1:47831/event/idle       # back to normal

Private and local

The agent connection is a request to your own machine. Nothing about your code, prompts or sessions is sent to Capybara Pet, only the three words above. If an agent run is interrupted and never reports back, he returns to normal on his own after three minutes.
