Pi Documentation Overview

Source: https://pi.dev/docs/latest

Pi is a minimal terminal coding harness. The core stays small and most workflow-specific behavior lives in TypeScript extensions, skills, prompt templates, themes, and Pi packages. Positioning on https://pi.dev/: "There are many agent harnesses but this one is yours" — four run modes (interactive, print/JSON, RPC, SDK), 15+ providers with mid-session model switching, tree-structured shareable sessions, steering and follow-up during a run, and extensible primitives instead of baked-in features.

Top-Level Areas

• Start here: quickstart, usage, providers, llama.cpp, security, containerization, settings, keybindings, sessions, compaction.
• Customization: extensions, skills, prompt templates, themes, Pi packages, custom models, custom providers.
• Programmatic usage: SDK, RPC mode, JSON event stream mode, TUI components.
• Reference: environment variables, session file format and SessionManager API.
• Platform setup: Windows, Termux, tmux, terminal setup, shell aliases.
• Development: local source setup, rebranding, debug logs, tests, package structure.

Quick Install

npm install -g --ignore-scripts @earendil-works/pi-coding-agent
pi

On Linux/macOS the installer is also available:

curl -fsSL https://pi.dev/install.sh | sh

pnpm and bun global installs work too (pnpm add -g --ignore-scripts ..., bun add -g --ignore-scripts ...).

Authenticate with /login for subscription providers or set API keys such as ANTHROPIC_API_KEY before startup.
