tu is an open-source terminal agent harness and automation utility maintained by Sahil Ahuja (sahil87). Built primarily with Node.js and integrating with fab-kit orchestration tools, it provides a command-line framework designed to coordinate automated tasks, scripts, and agentic workflows directly in developer environments. Operating as a CLI harness, tu structures tooling execution around extensible skill standards and modular components located within its Node.js runtime. It enables developers to execute discrete automation tasks, interface with project environments via directory-level configurations like direnv (.envrc), and execute scripted routines directly from the shell. Unlike standalone interactive coding agents, tu is structured as a lightweight execution harness that incorporates toolkit skill standards and fab-kit integrations. This design focuses on repeatable script execution, custom capability packaging, and environment-aware task runs rather than open-ended conversational code generation. tu is licensed under the open-source MIT License and is actively maintained on GitHub.
