Claude LIV Conventions

A Claude Code plugin that enforces opinionated conventions for Laravel/Inertia/Vue projects.

Why This Exists

When using Claude Code for Laravel/Inertia/Vue development, Claude may suggest patterns that don't align with project conventions. For example:

• Creating FormRequest classes when the project uses spatie/laravel-data DataClasses
• Writing Vue components without <script setup lang="ts">
• Placing files in flat directory structures instead of nested domain folders

This plugin intercepts Claude's tool usage and:

1. Blocks anti-patterns before they happen
2. Guides Claude towards the correct approach with helpful messages

What It Does

The plugin provides pre-tool hooks that run before Claude executes tools like Write, Edit, or Bash. Each hook validates the intended action and can:

• Allow - Let the action proceed
• Deny - Block the action with an explanation of the correct approach
• Ask - Prompt the user for confirmation

Included Hooks

Hook	Purpose
FormRequestBlocker	Blocks Laravel FormRequest creation, guides to DataClasses
VueScriptValidator	Ensures Vue files use <script setup lang="ts">

How It Works

┌─────────────────┐     ┌──────────────┐     ┌─────────────────┐
│  Claude wants   │────▶│  Hook runs   │────▶│  Action allowed │
│  to write file  │     │  validation  │     │  or blocked     │
└─────────────────┘     └──────────────┘     └─────────────────┘

1. Claude Code invokes a tool (e.g., Write to create a file)
2. The plugin's hooks receive the tool input (file path, content, etc.)
3. Hooks validate against conventions and return allow/deny/ask
4. If denied, Claude receives guidance on the correct approach

Hooks are Python scripts using the claude-hook-utils package for standardized input/output handling.

Requirements

• Python 3.10+ - For running hook scripts
• uv - Python package manager (hooks auto-install dependencies on first run)

If you're using a devcontainer, ensure these are installed in your container.
