Tau – Learn how coding agents are built

- **TwoTimesPi (2π)** is a boutique engineering studio (by ex-Sentry engineers) that builds custom AI coding agents for startups. "Tau" is their internal framework for constructing these agents. - The site is a technical deep-dive into how coding agents are architected: AI systems that write, debug, and refactor code autonomously using LLMs (GPT-4, Claude). Unlike Copilot-style autocomplete, these agents plan, run shell commands, edit files, run tests, and iterate. - Key patterns covered: tool-use (LLM accesses file system, terminal, linters), reflection (agent reviews and corrects its own work), and orchestration (coordinating sub-agents for specialized tasks). - This matters because the industry is shifting from AI-assisted autocomplete toward autonomous software engineering agents—and studios like 2π are defining how those agents are built under the hood.
