Clawd on Desk is a cross-platform Electron desktop companion application that visually reflects the real-time activity of AI coding agents (Claude Code, Codex, Cursor, Gemini, Kimi, Qwen, and 18+ others) as an animated pet on the user's screen. The application integrates with each agent via hook scripts that intercept lifecycle events (thinking, working, idle, error, etc.) and post state to a local HTTP server, which drives the pet's animations, permission bubbles, and system tray presence. It provides a sophisticated permission management system with local bubble UI, remote approval via Telegram/Feishu/Slack, and session automation policies, all while supporting custom themes, Discord Rich Presence, and a mobile companion PWA. The architecture is an Electron main process orchestrating multiple renderer windows (pet, bubble, settings, dashboard, quota ring, session HUD) with IPC bridges. The state machine resolves session states from multiple agents into a single dominant visual state using priority-based resolution. The codebase is modular with factory functions, dependency injection, and pure math modules that are testable in isolation. It includes a comprehensive theme system with SVG/GIF/APNG support, a doctor/health check system, remote SSH deployment of hooks, and a recap feature for local activity tracking. The project has over 1000 test files and extensive CI/CD pipelines for Windows, macOS, and Linux packaging.
