Source documentation, not instructions for this website. Review permissions before running any commands.
You are authoring an Unreal Engine Agent Skill: a named, reusable bundle of instructions that packages essential knowledge the agent either doesn't know or needs to pay close attention to. A skill can provide general best practices in a domain, guidance on a specific workflow, or a mix of both.
A good skill is:
Novel: The content should be things the agent doesn't already know or can't learn by using tools. If the agent could figure it out by calling a tool, don't put it in a skill.
Collegial: Write like you're briefing a knowledgeable colleague, not authoring documentation. Assume the reader understands Unreal. Give them what they need to act, not a full explanation of how everything works.
Flexible: Skills can include conceptual explanations, step-by-step instructions, or a mix. Use whichever form makes the guidance clearest for the task.
Durable: Don't embed property names, tool names, or other details that change over time. Skills that reference specific API names break silently when those names change.
Agnostic: Don't reference orchestration systems, role names, model names, or anything about how the agent is wired up. Skills should work regardless of the surrounding infrastructure.
Parsimonious: Every token costs context. Put them where they matter most and cut anything that isn't essential or evergreen. If a sentence wouldn't be missed, remove it.
Work through these questions before writing anything.
1. Does the skill already exist? Call ListSkills via MCP to see all registered skills in the project, then GetSkills on anything relevant. If the capability is already covered, point the user to the existing skill rather than creating a new one.
2. Choose the implementation path. Two paths exist and the choice depends on where the skill lives:
CreateSkill via MCP. No code required.Every Unreal skill has two fields.
Description: Loaded at discovery time, before the skill's full instructions are read. One or two sentences that clearly describe what the skill covers and when it applies.
Instructions: The skill's payload. The actual guidance the agent follows when the skill is active. Apply the principles above: focus on what tools can't teach and cut anything not essential.
The agent discovers and dispatches tools at runtime through the unreal-mcp meta-tools (list_toolsets, describe_toolset, call_tool), so write instructions that assume the agent will find the tools it needs rather than naming a fixed toolset list.
A Python skill is a UAgentSkill subclass defined in a Python file inside a plugin. Use this path when the skill belongs to a code plugin and should be version-controlled with the plugin.
Decorate the class with @agent_skill and inherit from unreal.AgentSkill. The two fields from the Structure section map to class attributes:
Description. Keep it to one or two sentences.instructions is a class attribute string containing the guidance loaded when the skill activates.import unreal
from toolset_registry.agent_skill import agent_skill
_INSTRUCTIONS = (
'Do X before Y, because Z.\n'
'Always verify the result after performing the operation.\n'
)
@agent_skill
class MySkill(unreal.AgentSkill):
"""Provides guidance on doing X in Unreal Engine.
Apply this skill whenever the user wants to accomplish X."""
instructions = _INSTRUCTIONS
Skills register themselves on import. Unless directed otherwise, place skill files in a skills/ subfolder within the plugin's Python package, import each one explicitly in that subfolder's __init__.py, and ensure init_unreal.py imports the skills package.
After editing a Python skill, reload the plugin's package before verifying. The editor won't pick up changes otherwise. Enable Remote Execution in Edit → Project Settings → Plugins → Python → Enable Remote Execution, then run:

A UAsset skill is a UAgentSkill instance saved as a Content Browser asset. Use this path for project-specific skills that don't belong in a plugin and require no code.
Use AgentSkillToolset via MCP. Start by calling ListSkills to see what exists, then either create or update:
Creating: Call CreateSkill with:
FolderPath: Content Browser folder, e.g. /Game/Skills/AssetName: PascalCase name, e.g. MyWorkflowSkillDescription: one or two sentences (see Structure above)Details: a FAgentSkillDetails with InstructionsUpdating: Call UpdateSkill with:

# Unreal Skill
You are authoring an Unreal Engine Agent Skill: a named, reusable bundle of instructions that packages essential knowledge the agent either doesn't know or needs to pay close attention to. A skill can provide general best practices in a domain, guidance on a specific workflow, or a mix of both.
## Principles
A good skill is:
**Novel**: The content should be things the agent doesn't already know or can't learn by using tools. If the agent could figure it out by calling a tool, don't put it in a skill.
**Collegial**: Write like you're briefing a knowledgeable colleague, not authoring documentation. Assume the reader understands Unreal. Give them what they need to act, not a full explanation of how everything works.
**Flexible**: Skills can include conceptual explanations, step-by-step instructions, or a mix. Use whichever form makes the guidance clearest for the task.
**Durable**: Don't embed property names, tool names, or other details that change over time. Skills that reference specific API names break silently when those names change.
**Agnostic**: Don't reference orchestration systems, role names, model names, or anything about how the agent is wired up. Skills should work regardless of the surrounding infrastructure.
**Parsimonious**: Every token costs context. Put them where they matter most and cut anything that isn't essential or evergreen. If a sentence wouldn't be missed, remove it.
## Before You Write
Work through these questions before writing anything.
**1. Does the skill already exist?** Call `ListSkills` via MCP to see all registered skills in the project, then `GetSkills` on anything relevant. If the capability is already covered, point the user to the existing skill rather than creating a new one.
**2. Choose the implementation path.** Two paths exist and the choice depends on where the skill lives:
- **Python class**: The right choice when the skill is part of a code plugin. It lives alongside the plugin's Python toolsets, is version-controlled with the plugin, and is registered automatically when the plugin loads.
- **UAsset**: The right choice when the skill is project-specific and doesn't belong in a plugin. Create it directly in the Content Browser using `CreateSkill` via MCP. No code required.
## Structure
Every Unreal skill has two fields.
**Description**: Loaded at discovery time, before the skill's full instructions are read. One or two sentences that clearly describe what the skill covers and when it applies.
**Instructions**: The skill's payload. The actual guidance the agent follows when the skill is active. Apply the principles above: focus on what tools can't teach and cut anything not essential.
The agent discovers and dispatches tools at runtime through the unreal-mcp meta-tools (`list_toolsets`, `describe_toolset`, `call_tool`), so write instructions that assume the agent will find the tools it needs rather than naming a fixed toolset list.
## Python Skills
A Python skill is a `UAgentSkill` subclass defined in a Python file inside a plugin. Use this path when the skill belongs to a code plugin and should be version-controlled with the plugin.
### Authoring
Decorate the class with `@agent_skill` and inherit from `unreal.AgentSkill`. The two fields from the Structure section map to class attributes:
- The class docstring becomes the `Description`. Keep it to one or two sentences.
- `instructions` is a class attribute string containing the guidance loaded when the skill activates.
```python
import unreal
from toolset_registry.agent_skill import agent_skill
_INSTRUCTIONS = (
'Do X before Y, because Z.\n'
'Always verify the result after performing the operation.\n'
)
@agent_skill
class MySkill(unreal.AgentSkill):
"""Provides guidance on doing X in Unreal Engine.
Apply this skill whenever the user wants to accomplish X."""
instructions = _INSTRUCTIONS
```
### Registration
Skills register themselves on import. Unless directed otherwise, place skill files in a `skills/` subfolder within the plugin's Python package, import each one explicitly in that subfolder's `__init__.py`, and ensure `init_unreal.py` imports the `skills` package.
### Reloading
After editing a Python skill, reload the plugin's package before verifying. The editor won't pick up changes otherwise. Enable Remote Execution in **Edit → Project Settings → Plugins → Python → Enable Remote Execution**, then run:
```bash
python Engine/Plugins/Experimental/ToolsetRegistry/Content/Python/toolset_registry/tests/reload_remote.py your_plugin
```
## UAsset Skills
A UAsset skill is a `UAgentSkill` instance saved as a Content Browser asset. Use this path for project-specific skills that don't belong in a plugin and require no code.
### Authoring
Use `AgentSkillToolset` via MCP. Start by calling `ListSkills` to see what exists, then either create or update:
**Creating**: Call `CreateSkill` with:
- `FolderPath`: Content Browser folder, e.g. `/Game/Skills/`
- `AssetName`: PascalCase name, e.g. `MyWorkflowSkill`
- `Description`: one or two sentences (see Structure above)
- `Details`: a `FAgentSkillDetails` with `Instructions`
**Updating**: Call `UpdateSkill` with:
- `SkillPath`: full path to the skill, e.g. `/Game/Skills/MyWorkflowSkill.MyWorkflowSkill_C`
- `Description`: revised description
- `Details`: revised `FAgentSkillDetails`
## Reviewing Your Work
Before handing off, verify the skill looks right by calling `GetSkills` on its path. Then read the description and instructions together as the agent will see them:
- **Description**: Does it clearly say when this skill applies? Would an agent reading only the description know whether to activate it for a given task?
- **Instructions**: Do they teach something the agent couldn't learn from the tools? Are they brief enough to be worth the context cost?
Skill source recorded
Skill instructions are recorded. This is not a runtime test, safety guarantee or compatibility certification.
Review before install: Avoid automatic install
Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.
Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
Repository metadata and review signals are advisory. Popularity, source discovery and successful execution are different facts.
Version reported in registry metadata; check source releases before relying on it.
