A skill can provide general best practices in a domain, guidance on a specific workflow, or a mix of both.\n\n## Principles\n\nA good skill is:\n\n**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.\n\n**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.\n\n**Flexible**: Skills can include conceptual explanations, step-by-step instructions, or a mix. Use whichever form makes the guidance clearest for the task.\n\n**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.\n\n**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.\n\n**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.\n\n## Before You Write\n\nWork through these questions before writing anything.\n\n**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.\n\n**2. Choose the implementation path.** Two paths exist and the choice depends on where the skill lives:\n\n- **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.\n- **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.\n\n## Structure\n\nEvery Unreal skill has two fields.\n\n**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.\n\n**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.\n\nThe 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.\n\n## Python Skills\n\nA 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.\n\n### Authoring\n\nDecorate the class with `@agent_skill` and inherit from `unreal.AgentSkill`. The two fields from the Structure section map to class attributes:\n\n- The class docstring becomes the `Description`. Keep it to one or two sentences.\n- `instructions` is a class attribute string containing the guidance loaded when the skill activates.\n\n```python\nimport unreal\n\nfrom toolset_registry.agent_skill import agent_skill\n\n_INSTRUCTIONS = (\n    'Do X before Y, because Z.\\n'\n    'Always verify the result after performing the operation.\\n'\n)\n\n@agent_skill\nclass MySkill(unreal.AgentSkill):\n    \"\"\"Provides guidance on doing X in Unreal Engine.\n    Apply this skill whenever the user wants to accomplish X.\"\"\"\n\n    instructions = _INSTRUCTIONS\n```\n\n### Registration\n\nSkills 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.\n\n### Reloading\n\nAfter 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:\n\n```bash\npython Engine/Plugins/Experimental/ToolsetRegistry/Content/Python/toolset_registry/tests/reload_remote.py your_plugin\n```\n\n## UAsset Skills\n\nA 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.\n\n### Authoring\n\nUse `AgentSkillToolset` via MCP. Start by calling `ListSkills` to see what exists, then either create or update:\n\n**Creating**: Call `CreateSkill` with:\n- `FolderPath`: Content Browser folder, e.g. `/Game/Skills/`\n- `AssetName`: PascalCase name, e.g. `MyWorkflowSkill`\n- `Description`: one or two sentences (see Structure above)\n- `Details`: a `FAgentSkillDetails` with `Instructions`\n\n**Updating**: Call `UpdateSkill` with:\n- `SkillPath`: full path to the skill, e.g. `/Game/Skills/MyWorkflowSkill.MyWorkflowSkill_C`\n- `Description`: revised description\n- `Details`: revised `FAgentSkillDetails`\n\n## Reviewing Your Work\n\nBefore 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:\n\n- **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?\n- **Instructions**: Do they teach something the agent couldn't learn from the tools? Are they brief enough to be worth the context cost?\n","tagline":"Use this skill when creating, editing, or reviewing an Unreal Engine Agent Skill, a named bundle of instructions registered with the unreal-mcp server (distinct from Claude Code's harness skills under `.claude/skills/`).
