Ue5 Dev Tools

UE5 Dev Tools (Claude Plugin)

A Claude plugin to assist with Unreal Engine 5 Python development. Provides API validation, querying, and autocomplete support.

Features

• API Validation: Checks if UE5 API calls in Python scripts are correct, identifies deprecated APIs and parameter errors.
• Smart Mock: Automatically detects Python Stubs generated by UE5 projects on first run and converts them to runtime-usable Mock modules.
• Metadata Integration: Automatically scans UE5 source code (if available) and extracts C++ metadata to enhance validation accuracy.
• Anti-Hallucination: Strictly controls /search-api output to prevent AI from fabricating non-existent APIs.

Installation

This plugin is designed as a local Claude Plugin.

1. Add Local Marketplace Run in the current directory (root of ue5-dev-tools):

   claude plugin marketplace add .
   

2. Install Plugin

   claude plugin install ue5-dev-tools
   

3. Install Git Hooks (Optional, for development) If you are a plugin developer, installing git hooks can automatically manage version numbers:

   cd ue5-dev-tools
   ./scripts/install-hooks.sh
   

   This enables automatic version increment: automatically increments the plugin.json version by +0.0.1 with each commit.

Usage

Open Claude in your UE5 project directory and use the following commands:

• /validate-script <file.py>: Validate the specified script. Automatically generates the Mock module on first run.
• /search-api <query>: Search UE5 Python API definitions with fuzzy or exact matching.

Requirements

• Python 3.8+
• Claude Code
• (Optional) UE5 source code (for enhanced metadata analysis)
• (Optional) Intermediate/PythonStub/unreal.py generated by UE5 project (for generating Mock)
