Pi Monorepo

Looking for the pi coding agent? See packages/coding-agent for installation and usage.

Tools for building AI agents and managing LLM deployments.

Packages

Package	Description
@mariozechner/pi-ai	Unified multi-provider LLM API (OpenAI, Anthropic, Google, etc.)
@mariozechner/pi-agent-core	Agent runtime with tool calling and state management
@mariozechner/pi-coding-agent	Interactive coding agent CLI
@mariozechner/pi-mom	Slack bot that delegates messages to the pi coding agent
@mariozechner/pi-tui	Terminal UI library with differential rendering
@mariozechner/pi-web-ui	Web components for AI chat interfaces
@mariozechner/pi-pods	CLI for managing vLLM deployments on GPU pods

Development

Setup

npm install          # Install all dependencies
npm run build        # Build all packages
npm run check        # Lint, format, and type check

Note: npm run check requires npm run build to be run first. The web-ui package uses tsc which needs compiled .d.ts files from dependencies.

CI

GitHub Actions runs on push to main and on pull requests. The workflow runs npm run check and npm run test for each package in parallel.

Do not add LLM API keys as secrets to this repository. Tests that require LLM access use describe.skipIf() to skip when API keys are missing. This is intentional:

• PRs from external contributors would have access to secrets in the CI environment
• Malicious PR code could exfiltrate API keys
• Tests that need LLM calls are skipped on CI and run locally by developers who have keys configured

If you need to run LLM-dependent tests, run them locally with your own API keys.

Development

Start watch builds for all packages:

npm run dev

Then run with tsx:

cd packages/coding-agent && npx tsx src/cli.ts
cd packages/pods && npx tsx src/cli.ts

To run tests that don't require an LLM endpoint:

./test.sh

Versioning (Lockstep)

All packages MUST always have the same version number. Use these commands to bump versions:

npm run version:patch    # 0.7.5 -> 0.7.6
npm run version:minor    # 0.7.5 -> 0.8.0
npm run version:major    # 0.7.5 -> 1.0.0

These commands:

1. Update all package versions to the same number
2. Update inter-package dependency versions (e.g., pi-agent depends on pi-ai@^0.7.7)
3. Update package-lock.json

Never manually edit version numbers. The lockstep system ensures consistency across the monorepo.

Publishing

npm run release:patch    # Bug fixes
npm run release:minor    # New features
npm run release:major    # Breaking changes

This handles version bump, CHANGELOG updates, commit, tag, publish, and push.
