Pi (Pi Agent Harness) is a leading agent runtime in the 2026 AI agent engineering landscape (67.1k★).

When to use this skill

Self-extensible interactive coding agent CLI (@earendil-works/pi-coding-agent)
pi-agent-core: reusable agent runtime with tool calling and state management
pi-ai: unified multi-provider LLM API (OpenAI, Anthropic, Google, ...)
pi-tui: terminal UI library with differential rendering
Extensions, themes, and custom tools — the agent can extend itself
Session trees with branching state
Sibling project pi-chat for Slack/chat automation
Ecosystem overlap: None; oh-my-gods agent-workflow covers day-to-day loops on other runtimes; pi-agent covers building on/with the pi harness itself
