🍕 Pizza

Pi with extra toppings — an opinionated Pi setup, packaged as a set of extensions.

📦 Install

curl -fsSL https://raw.githubusercontent.com/johnnygreco/pizza/main/install.sh | bash

Requires Node.js >= 20.6 and Pi. Installs to ~/.pizza. Each Pizza release declares the minimum Pi version it supports. The installer enforces that floor, and Pizza warns at session start only when Pi is older than it.

# Pin a specific version
curl -fsSL .../install.sh | bash -s -- --version 0.2.0

# Uninstall
curl -fsSL .../install.sh | bash -s -- --uninstall

Set PIZZA_HOME to change the install directory.

🧩 What's in the box

Commands

/pizza — Pizza version, Pi compatibility, model, cwd, active theme, banner layout, and context at a glance.

• /pizza resources — print the resources section using the same formatting as the banner.
• /pizza shortcuts — print the shortcuts + prefixes section using the same formatting as the banner.
• /pizza help — show quick usage.

/theme — Pick a theme interactively, or /theme <name|next|prev> to switch directly. Pizza's palette follows Pi's active theme.

• Ctrl+Q — cycle theme forward

/create-subagent <description> — Generate a reviewable Pizza subagent draft, then run once, keep for session, save permanently, preview context, or cancel.

/subagents — Manage subagent definitions, running/recent runs, and the review inbox. Use the subagent tool action activity with a run id to inspect what a running subagent is currently doing.

/remove-subagent <name> — Remove a saved or session-scoped subagent. Builtins cannot be deleted.

:<agent-name> <prompt> — Shortcut syntax to run an existing subagent directly, e.g. :reviewer review the current diff. Use :reviewer to run with no explicit user prompt.

• :subagents or :agents list — quick list of existing subagents.

Extensions

Pizza now ships only its first-party extensions, including pizza-subagents for scoped delegation. Add third-party Pi extensions separately as you need them.
