LeanCode AI Plugins

LeanCode's shared AI plugins for Claude Code, focused on Flutter development.

Supported clients

• Claude Code — installed via the LeanCode plugin marketplace in Claude Code.

Install

These plugins are distributed as a Claude Code plugin marketplace. Installing is a two-step process — add the marketplace once, then install the plugins you want. You do not need to clone this repo for day-to-day usage. For the full reference, see Claude Code's Discover and install plugins docs.

1. Add the marketplace

In Claude Code, add this repository as a marketplace by its GitHub owner/repo:

/plugin marketplace add leancodepl/ai-plugins

This registers the catalog so you can browse it — nothing is installed yet. (The full git URL works too: /plugin marketplace add https://github.com/leancodepl/ai-plugins.git.)

2. Install the plugins you need

Browse the catalog with /plugin (the Discover tab), or install directly by name. Plugins install from the leancode-ai-plugins marketplace:

/plugin install flutter-bloc@leancode-ai-plugins

Pick only the plugins that match your project — each is independently installable. After installing, run /reload-plugins to activate them.

Tip: Install lean-core first and run /lean-core-usage for a guided tour of the whole marketplace.

Team setup (optional)

To have Claude Code prompt collaborators to install the marketplace automatically, add it to your project's .claude/settings.json:

{
  "extraKnownMarketplaces": {
    "leancode-ai-plugins": {
      "source": {
        "source": "github",
        "repo": "leancodepl/ai-plugins"
      }
    }
  }
}

Per-plugin setup

Most plugins are pure rules and skills with no setup. A few need one-time tooling or MCP setup — finish it from the plugin's README.md:

• flutter-patrol - Patrol CLI and Patrol MCP
• flutter-marionette - Marionette MCP and app-side binding

Available plugins

Getting started

• lean-core - marketplace entry point: /lean-core-usage explains what's available, /lean-contribute walks you through opening a PR

Project foundations

• flutter-leancode-architecture - project structure, error handling, logging, plus architecture review and feature scaffolding skills
• flutter-di - provider-based dependency injection, page-root providers, GlobalProviders, and async initialization patterns
• flutter-navigation - auto_route and go_router, typed routes, route guards, route tree organization, and deep links
• flutter-analytics - analytics IDs, page/button tracking, plus skills to scaffold IDs and review coverage
• flutter-localization - ARB workflows, POEditor, poe2arb, and l10n(context)

State and data

• flutter-bloc - BLoC/Cubit conventions, state modeling, presentation side effects, bloc_presentation, and flutter_hooks
• flutter-cubit-utils - QueryCubit, PaginatedQueryCubit, RequestCubit, and recipes for lists, details, and actions
• flutter-cqrs - CQRS contracts, repositories, direct cqrs.run / cqrs.get usage, and CQRS-backed cubits
• flutter-forms - leancode_forms, validation behavior, naming conventions, and form cubit patterns

UI and verification

• flutter-ui - design-system-driven UI, loading/error patterns, localized presentation text, and UI implementation checklists
• flutter-patrol - Patrol test architecture, key conventions, and Patrol MCP workflow for AI-assisted E2E work
• flutter-marionette - runtime interaction with a live debug app through Marionette MCP for exploration, smoke checks, and UI debugging

Every plugin has a -usage skill

Once a plugin is installed, it exposes a /<plugin-name>-usage skill — for example /flutter-bloc-usage, /flutter-cqrs-usage, /flutter-ui-usage. Run it to see what the plugin covers, its conventions, and example prompts to try next. It's the fastest way to learn a plugin without reading its full README.md. If you're not sure where to begin, run /lean-core-usage for a tour of the whole marketplace.

Repo layout

• plugins/<plugin-name>/ - one self-contained plugin
• plugins/<plugin-name>/skills/ - skills the plugin ships
• plugins/<plugin-name>/skills/<skill>/references/ - supporting reference material a skill loads on demand
• plugins/<plugin-name>/.claude-plugin/ - plugin manifest
• .claude-plugin/marketplace.json - marketplace index
