Cate is an open-source agent harness and orchestrator developed by 0-AI-UG. Built on TypeScript, Vite, and Electron, it provides an orchestration runtime for coding agents to execute development skills, manage workspace tasks, and interact directly with terminal environments. In daily operations, Cate manages agent execution sessions with integrated terminal handling and a configurable skill architecture. Developers configure agent capabilities and behaviors using workspace skill definitions and agent configuration files (such as AGENTS.md and CLAUDE.md), enabling agents to inspect codebases, execute terminal commands, run tests, and manage remote terminal connections. What differentiates Cate is its dual nature as an Electron-packaged desktop harness backed by modular skill registries and terminal orchestration. Rather than functioning solely as a terminal REPL, it packages agent control, skill integration, and resilient terminal lifecycle management (including remote session reconnects) into a unified application. Cate is open-source under a standard open repository license, self-hosted, and free to use. Model usage and execution costs depend on the upstream provider APIs configured for your underlying agent setup.
