What it does

A local‑first, cross‑platform desktop workspace that lets you run Claude‑based coding agents with Git worktree management, code diffs, multi‑model support, and instant messaging integrations.

When to use it
  • You need a self‑hosted UI for Claude‑powered coding assistants that can edit, diff, and commit code without leaving your desktop.
  • Your team works across WeChat, Feishu, DingTalk, Telegram or WhatsApp and wants to invoke the same coding agent from any of those channels.
  • You want to experiment with multiple Claude models, computer‑use plugins, or custom “desktop pets” that stay aware of the current coding task.
Ready-to-paste prompt
Create a new worktree named `feature/payment`, scaffold a Stripe checkout component in `src/components/Checkout.tsx`, run `npm test` to ensure it passes, and open a pull request on GitHub.
Heads up: The app requires Node 20+ and a valid Claude API key; without the key the agents will start but instantly error out, and the UI will show “Missing CLAUDE_API_KEY”.
