Built-in extensions (mcp, llama.cpp, codemode, tool-search) are now extension resources like files: the package manager resolves them as builtin:<name>, the extensions setting disables them with -builtin:<name> (per project too), pi config lists them, and --no-extensions turns them off unless loaded with -e builtin:<name>. They load after project trust is resolved and after file and package extensions. Built-in extensions and tools are named builtin:<name> in errors, diagnostics, RPC source info, and bug reports. |

Pi
Pi is a minimal, extensible AI agent for the terminal. Adapt Pi to your workflow, not the other way around.
Ask Pi to create the prompt templates, skills, extensions, and themes you need, or install a Pi package. Use Pi directly, automate it in print, JSON, or RPC mode, or build applications with the TypeScript SDK.
Getting started
Install the command-line interface with npm:
npm install -g --ignore-scripts @earendil-works/pi-coding-agent
This requires Node.js 22.19 or newer. Pi does not require dependency lifecycle scripts for a normal npm installation.
On macOS or Linux, you can instead use the installer:
curl -fsSL https://pi.dev/install.sh | sh
Start Pi in the directory where you want it to work:
cd /path/to/project
pi
For a built-in AI provider, run /login inside Pi to connect a subscription or API key. Then give Pi a task.
See the documentation for full setup and usage instructions.
Development
Clone the repository, install its dependencies, and run Pi from source:
git clone https://github.com/earendil-works/pi
cd pi
npm install --ignore-scripts
./pi-test.sh
pi-test.sh can be called from any directory and preserves the caller's working directory.
Before submitting changes, run:
npm run check
./test.sh
