An LLM-powered repository agent designed to assist developers and teams in generating documentation and understanding repositories quickly.
12-Factor Agents
A set of principles for building LLM powered software intended for production users.

About 12-Factor Agents
12-Factor Agents is a public repository outlining a set of 12 principles for building LLM-powered software suitable for production customer use, modeled after the 12 Factor Apps framework for traditional software development. The principles cover core engineering practices including natural language to tool call translation, prompt and context ownership, structured tool outputs, unified state management, human-in-the-loop tooling, error handling, and stateless agent design, with the goal of improving the reliability, scalability, and maintainability of LLM applications.
