About pi
Pi is a modular agent toolkit written in TypeScript for building and running terminal based AI coding agents. It lives in the developer tooling ecosystem and provides composable packages for LLM integration, agent orchestration, and terminal UI rendering. The project centers on @earendil works/pi coding agent , an interactive CLI agent, supported by core runtime, AI abstraction, and TUI libraries.
About codegraph
CodeGraph is a pre indexed code knowledge graph that runs locally and wires into AI coding agents — Claude Code, Cursor, Codex, Gemini, OpenCode, AntiGravity, Kiro, GitHub Copilot, and Hermes Agent — so those agents query a semantic map of the codebase instead of reading files one at a time.
