AI Agent Skills

Each YominUnreal plugin ships with a dedicated AI agent skill — a SKILL.md file that teaches any LLM-powered coding assistant the full DSL of that plugin. Point your agent at the right skill and it can author .llmui / .llmmat / .llmstate / .llmmetasound files, or drive the running UE editor through the LLMEasyShell CLI, without ever opening the graph editor.

The Six Skills

🎨 Asset Authoring Skills (DSL Generation)

These skills teach the agent how to write JSON files for a specific asset type. The plugin in the editor turns that JSON into a real engine asset.

	Skill	What it teaches	Source file
🎨	llm-dynamic-ui	UMG Widget Blueprints from .llmui	skills/llm-dynamic-ui/SKILL.md
🎭	llm-material	Material assets from .llmmat	skills/llm-material/SKILL.md
🌲	llm-statetree	StateTree AI from .llmstate	skills/llm-statetree/SKILL.md
🔊	llm-metasound	MetaSound audio from .llmmetasound	skills/llm-metasound/SKILL.md

🛠️ Editor Control Skills (Runtime Operation)

These skills teach the agent how to drive a running UE editor through the LLMEasyShell CLI — query scenes, modify actor properties, call blueprint functions, trigger Live Coding, take screenshots.

	Skill	What it teaches	Source file
🛠️	llm-easy-shell	Full read/write access — 37 native commands + hundreds of Python sub-commands	skills/llm-easy-shell/SKILL.md
🛠️	llm-easy-shell-lite	Read-only subset — 9 safe exploration commands	skills/llm-easy-shell-lite/SKILL.md

How a Skill Works

A SKILL.md is plain Markdown with two parts:

1. YAML frontmatter — name + description that the AI agent uses to decide when to load the skill (matched against the user's request).
2. Markdown body — the full DSL schema, supported nodes / widgets, authoring patterns, and command references.

When you ask the agent a question, it scans the frontmatter of all installed skills. If a skill's description matches your request, the agent loads the body and follows it. No code is scraped from the editor, no graph screenshots are sent to the LLM — the skill is the only source of truth.

Where to Put Skills

Each AI tool has its own convention. See Installation for the exact path used by Claude Code, OpenCode, Cursor, Codex, and others.

The short version:

<your UE project>/                     # The folder containing your .uproject
├── MyProject.uproject
└── .claude/
    └── skills/
        ├── llm-dynamic-ui/
        │   └── SKILL.md
        ├── llm-material/
        │   └── SKILL.md
        ├── llm-statetree/
        │   └── SKILL.md
        ├── llm-metasound/
        │   └── SKILL.md
        ├── llm-easy-shell/
        │   └── SKILL.md
        └── llm-easy-shell-lite/
            └── SKILL.md

That is — drop the skill folder next to your .uproject and most tools will pick it up automatically.
