Pi – a minimal terminal coding harness

3 hours ago

Pi is a minimal terminal coding harness that can be extended with TypeScript extensions, skills, prompt templates, and themes.
It supports four modes: interactive, print/JSON, RPC, and SDK.
Pi integrates with multiple AI providers like Anthropic, OpenAI, Google, Azure, and more, with authentication via API keys or OAuth.
Users can switch models mid-session and customize providers and models via models.json or extensions.
Sessions are stored as trees, allowing navigation to any previous point and continuation from there.
Pi supports exporting sessions to HTML or uploading to GitHub gists for sharing.
It features dynamic context management, auto-summarization, and customizable compaction.
Skills and prompt templates allow for progressive disclosure and reusable prompts.
Pi is highly extensible, allowing users to build features like sub-agents, plan mode, and more via extensions.
Packages can be installed from npm or git, and versions can be pinned or updated.
Pi supports interactive, print/JSON, RPC, and SDK usage modes.
The tool is designed to be minimal and extensible, avoiding built-in features like MCP, sub-agents, and permission popups.
Community support is available via GitHub for issues and Discord for discussion.
