Pi overview

Pi is a terminal coding agent from earendil-works/pi, integrated into the v6 catalog through the adapters adapter. The repo is structured as a multi-package workspace: - packages/ai — AI provider abstraction layer supporting Anthropic, OpenAI (responses, completions, codex-responses), Azure OpenAI, Google, Vertex, Bedrock, Cloudflare, Mistral, and GitHub Copilot. - packages/agent — AgentHarness with compaction (branch summarization), session management, skills (formatSkillInvocation), prompt templates, and execution-env abstraction. - packages/coding-agent — The CLI coding agent that composes the agent harness into a full user-facing product with modes, config, migrations, and package-manager integration. The coding-agent is the top-level CLI entry point (`pi` command) that layers on the harness from packages/agent.
