Tau agent
Coding agent by alejandro-ao at Hugging Face: a Python port of pi-agent ("exactly as minimalist... scores pretty much exactly the same in most benchmarks"), with native local-model support via llama.cpp and an extension system whose extensions can add widgets to the TUI sidebar. A Tau-Herder extension (by Ryan Dolphin) integrates it with herder; demoed orchestrating Herder itself โ creating a session, running Pi inside it, and relaying a prompt (agent-orchestrating-multiplexer).
