At its core, Pi offers a unified API for interacting with multiple Large Language Models (LLMs) like OpenAI, Anthropic, and Google, abstracting away provider-specific complexities. The project includes a powerful agent runtime with tool calling capabilities and state management, alongside an interactive coding agent CLI that empowers developers with AI-assisted coding. Built with modularity in mind, Pi is a collection of packages, each serving a specific purpose, from a terminal UI library to telemetry contracts.\n\n## Installation\nTo get started with Pi Agent Harness, you can install its packages via npm. For the interactive coding agent CLI, use the following command:\n\nbash\nnpm install -g @earendil-works/pi-coding-agent\n\n\nFor development, clone the repository and install dependencies:\n\nbash\nnpm install --ignore-scripts\nnpm run build\n\n\n## Examples\nPi's primary example is its interactive coding agent CLI, `@earendil-works/pi-coding-agent`. This agent can assist with coding tasks directly from your terminal. You can ask the agent to explain itself, generate code, or refactor existing solutions. The project website, [pi.dev](https://pi.dev \"Visit pi.dev\" target=\"_blank\"), offers various demos showcasing the agent's capabilities in real-world scenarios. Additionally, the unified LLM API (`@earendil-works/pi-ai`) allows developers to easily integrate different LLMs into their applications, providing a consistent interface across providers.\n\n## Why Use It\nPi Agent Harness stands out for several reasons. Its unified LLM API simplifies integration with multiple AI providers, offering flexibility and future-proofing. The robust agent runtime supports complex agent behaviors, including tool use and state management, making it suitable for sophisticated applications. The interactive coding agent CLI enhances developer productivity by bringing AI assistance directly to the command line. Furthermore, Pi emphasizes security with supply-chain hardening practices and offers comprehensive containerization options for secure execution, allowing users to sandbox agents with patterns like Gondolin extension, Plain Docker, or OpenShell. Its modular architecture, built in TypeScript, ensures maintainability and extensibility.\n\n## Links\n*   **GitHub Repository:** [https://github.com/earendil-works/pi](https://github.com/earendil-works/pi \"GitHub Repository\" target=\"_blank\")\n*   **Project Website:** [https://pi.dev](https://pi.dev \"Project Website\" target=\"_blank\")\n*   **Documentation:** [https://pi.dev/docs/latest](https://pi.dev/docs/latest \"Documentation\" target=\"_blank\")\n*   **Discord Community:** [https://discord.com/invite/3cU7Bz4UPx](https://discord.com/invite/3cU7Bz4UPx \"Discord Community\" target=\"_blank\")","metrics":{"detailViews":0,"githubClicks":0},"dates":{"published":null,"modified":"2026-08-10T16:11:22.000Z"}}
