Create a new Agent Skill for our level-dressing workflow and register it.About this skill
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/). Trigger when the user wants to add or change a skill that the in-editor agent will load. SKIP for: authoring a toolset (use create-toolset), invoking an existing skill at runtime (use unreal-mcp), editing harness-level Claude Code skills under .claude/skills/ or ~/.claude/skills/, or generic uses of the word 'skill'.
