## Purpose

Provide a single Unreal Engine skill entrypoint with deterministic Hardness governance, auditable delegation, and strict verification gates.

## When To Use

- Any request involving Unreal Engine, UE5, `.uproject`, C++ gameplay systems, Blueprint + C++ integration, Enhanced Input, GAS, replication, or plugin behavior.

---

## Non-Negotiables

- Zero assumptions: never invent asset names, module names, plugin states, or engine version.
- Discovery first, then implementation.
- Writer/reviewer separation for `M/H`.
- `M/H` requests are incomplete unless verification evidence is present.
- If reviewer separation is impossible, output `Status: BLOCKED` (never self-approve).
- Evaluate scriptability first; if a task is scriptable, prefer script/harness execution over manual repeated steps.
- Agent orchestration must strictly follow AgentHardness philosophy (intensity, delegation depth, and evidence depth must match risk/complexity).

## 快速参考卡

### Hardness 选择

| 级别 | 触发条件 |
|------|---------|
| **H** | 跨模块重构 / 复制+GAS / 插件不确定 / 安全敏感 |
| **M** | 多文件变更 / 调试评审 / 无 H 触发条件 |
| **L** | 单命令 / 窄范围 / 低风险 Q&A |

### 后端选择

| 场景 | 后端 |
|------|------|
| Widget 创建/编辑 | MCP (umg-ui-agent) |
| Actor 操作 | MCP (ue-core-agent) |
| PIE 测试/截图 | MCP (ue-core-agent) |
| 项目健康检查 | CLI (cli-anything) |
| 离线 UMG 分析 | CLI (cli-anything) |

### 输出契约 (必需字段)

```
Hardness: L|M|H
Delegation Plan: [团队/角色/车道]
Scriptability: scriptable|non-scriptable + [path]
Execution Backend: mcp|cli-anything|native-cli
Verification Evidence: [通过/未验证项]
Status: DONE|BLOCKED
```
