Claude Code skills

This repository is also a Claude Code plugin marketplace. Its plugin, ueagent, adds skills that drive the editor through UEAgent's tools, and one that writes new skills.

Install

In Claude Code:

/plugin install ueagent --marketplace CarlxsMG/UEAgent

On Claude Code versions before 2.1.275, add the marketplace first:

/plugin marketplace add CarlxsMG/UEAgent
/plugin install ueagent@ueagent

The skills need UEAgent's MCP server connected (see Clients).

The skills

Skill	What it does
/ueagent:skill-builder	Turns a workflow you want to repeat into a new skill
/ueagent:blueprint-actor	A Blueprint actor from a description: components, graph, a clean compile, and an instance in the level
/ueagent:project-audit	What is broken and what can go in the project or a folder, most serious first; it changes nothing
/ueagent:level-lighting	Outdoor lighting (sun, sky, sky light, fog) for noon, a sunset or an overcast sky, and a screenshot

Type the command, or just ask: Claude loads a skill by itself when a request matches it.

Building your own skills

/ueagent:skill-builder <the workflow> makes a skill out of a task you do often, such as "set up a pickup with a rotating mesh and a sound" or "import a character and make its AnimBP":

1. It agrees with you on the request, what changes between runs, and what "done" looks like.
2. It finds the tools the task needs, and reads their descriptions for traps.
3. It runs the task once in the editor, on a target you choose, reading every answer: refusals, readback warnings and ignored parameters. Each call is one undo step, so a failed attempt is rolled back and tried again.
4. It writes the skill, .claude/skills/<name>/SKILL.md in the project or ~/.claude/skills/<name>/SKILL.md for every project, with the steps, the check that proves the result and the pitfalls it met.
5. It runs the new skill on a fresh target and fixes what differed.

The three other skills in the plugin follow the same format, so they also serve as examples.
