What problem does it solve? Working on Unreal Engine projects with an AI agent requires knowing which tools to call, how to avoid editor crashes, and how to handle engine-specific quirks like .uasset path rules, TMap INI serialization, and null pointer crashes. This Skill provides the mandatory entry-point instructions that route every Unreal Engine task to the correct MCP server and enforce coding guardrails. ## Core Features & Use Cases - Dual-MCP Tool Routing: Directs Blueprint/UMG/level edits to the in-editor unrealengine server (port 18777) and C++ semantic queries to the cpp-ast-rag AST server, with fallback to documentation search for built-in engine classes. - Editor Lifecycle Workflows: Provides commands for building the project with Unreal Build Tool, launching the editor safely (including multiplayer/EOS login configurations), and triggering compilation without manual terminal builds. - Crash Prevention Guardrails: Enforces pointer validation for Data Assets, safe UI event handling, correct TMap config formatting, and Python script execution via scratch files to avoid PowerShell escaping failures. - Use Case: When asked to add a health component to a character Blueprint, the agent consults this Skill first to learn it must use Unreal paths like /Game/..., call the in-editor MCP tools rather than shell commands, and read the blueprint-authoring sub-skill before modifying nodes. ## Quick Start Ask the agent to modify a Blueprint or C++ class in your Unreal project and it will load these instructions to route the task correctly.
