Was ist Pi Coding Agent?

Pi is a minimal, highly customizable terminal-based coding harness and agent designed to adapt seamlessly to existing developer workflows. Unlike rigid, sealed products that enforce specific methodologies, Pi acts as an extensible framework where users can build or install commands, tools, providers, or custom UI tweaks on the fly. It ships with powerful default features but intentionally skips heavy, pre-baked abstractions like sub-agents, permission gates, background bash execution, or built-in plan modes. Instead, developers can easily extend Pi using TypeScript-based packages shared via npm or git, allowing it to act as a truly tailored terminal companion that can even be scripted, run in RPC mode, or embedded into third-party applications via an SDK.

So benutzt du es

To use Pi
install it via the terminal using curl
PowerShell
npm
pnpm
or bun (for example
run `npm install -g --ignore-scripts @earendil-works/pi-coding-agent`). Once installed
developers can start an interactive TUI session
run it in print mode using `pi -p "query"` for shell scripting
or switch models mid-session using `/model` or `Ctrl+L`. Users can customize its functionality by editing configurations like `models.json` or installing extensions directly using commands like `pi install npm:@foo/pi-tools`.
