Development

See AGENTS.md for additional guidelines.

Setup

git clone https://github.com/badlogic/pi-mono
cd pi-mono
npm install
npm run build

Run from source:

./pi-test.sh

Forking / Rebranding

Configure via package.json:

{
  "piConfig": {
    "name": "pi",
    "configDir": ".pi"
  }
}

Change name, configDir, and bin field for your fork. Affects CLI banner, config paths, and environment variable names.

Path Resolution

Three execution modes: npm install, standalone binary, tsx from source.

Always use src/config.ts for package assets:

import { getPackageDir, getThemeDir } from "./config.js";

Never use __dirname directly for package assets.

Debug Command

/debug (hidden) writes to ~/.pi/agent/pi-debug.log:

  • Rendered TUI lines with ANSI codes
  • Last messages sent to the LLM

Testing

./test.sh                         # Run non-LLM tests (no API keys needed)
npm test                          # Run all tests
npm test -- test/specific.test.ts # Run specific test
