How to Build a Coding Agent — 3-Layer Architecture

A first sneak peek at Tau, a modular educational coding agent inspired by Pi. In this video I walk through the current terminal UI, show how sessions, tools, skills, prompts, and context are exposed, and explain the architecture behind Tau: a provider/model layer, a reusable agent harness, and the coding-agent application layer. --- 🤓 *Topics Covered* - Tau coding agent sneak peek - Agent architecture and harness design - Python TUI with Textual --- ⏱️ *Timestamps* 0:00 Introducing Tau 1:03 Tau UI demo 3:43 Architecture: Tau AI, Tau agent, and Tau coding --- 🔗 *Links* - Pi: https://pi.dev/ - Tau: https://github.com/alejandro-ao/tau --- 👋 *Connect with me* - My website: https://alejandro-ao.com/ - X (Twitter): https://x.com/_alejandroao - LinkedIn: https://www.linkedin.com/in/alejandro-ao/ - Courses: https://aibootcamp.dev/
