Pi Coding Agent in AI answers

Pi is a minimal, extensible agent harness that you adapt to your workflows by adding extensions, skills, prompt templates, and themes, packaging and sharing them via npm or git. It provides a text-based UI with four modes (interactive, print/JSON, RPC, SDK), supports switching providers and models mid-session, and lets you branch and share session trees, export conversations to HTML, or publish them as a GitHub gist. Designed to be customizable rather than feature-complete out of the box, Pi installs via curl or common package managers and enables context engineering, script generation, and on-the-fly harness customization.
