Pi: A hackable terminal harness for building custom AI coding agent workflows
By

Warm and crisp on the edges. A bagel with a bit of bite.
Summary
Pi is a minimal, hackable terminal harness for building custom AI coding agent workflows. It keeps the core small and clean, allowing users to add, modify, or replace components through extensions, skills, and packages. Originally gaining attention as the harness underneath OpenClaw, Pi is now showing strong presence in the OpenAI ecosystem, with usage share comparable to Opencode. Users can customize context management, sub-agents, permissions, and workflows, and share configurations as Pi packages via npm or git.
Key quotes
· 5 pulledPi is a minimal, hackable terminal harness for building the AI coding agent workflow you actually want.
It keeps the core small and clean, then gives you the freedom to add, modify, or replace almost anything through extensions, skills, and packages.
Context management, sub-agents, permissions, custom workflows — you can make it behave exactly how you like.
Pi first caught a lot of attention as the harness underneath @OpenClaw.
It's astonishing that Pi and @opencode have roughly similar usage share.
