AI agents that plug into CI/CD to scope, code, validate, and merge fixes end-to-end in sandbox environments.
Pi is a minimal, opinionated terminal-based coding agent created by Mario Zechner, the creator of libGDX. It ships with just four core tools—read, write, edit, and bash—and a system prompt under 1,000 tokens, emphasizing simplicity and extensibility. Pi supports TypeScript extensions and skills for customization, and it powered the OpenClaw project that reached over 145,000 GitHub stars.
