Pi vs CC — Extension Playground

Infrastructure Access

Always read .claude/infra.md at the start of every session — it contains live credentials and connection details.

Pi Coding Agent extension examples and experiments.

Tooling

• Package manager: bun (not npm/yarn/pnpm)
• Task runner: just (see justfile)
• Extensions run via: pi -e extensions/<name>.ts

Project Structure

• extensions/ — Pi extension source files (.ts)
• specs/ — Feature specifications
• .pi/agents/ — Agent definitions for agent-team extension
• .pi/agent-sessions/ — Ephemeral session files (gitignored)

Conventions

• Extensions are standalone .ts files loaded by Pi's jiti runtime
• Available imports: @mariozechner/pi-coding-agent, @mariozechner/pi-tui, @mariozechner/pi-ai, @sinclair/typebox, plus any deps in package.json
• Register tools at the top level of the extension function (not inside event handlers)
• Use isToolCallEventType() for type-safe tool_call event narrowing
