Unreal MetaSound

路由

处理 MetaSound 资产、节点、接口、图连接或 MCP 自动化时使用本 Skill。开始前读取 references/metasound-code-study.zh-CN.md。

同时按需读取这些相关 Skill：

orion-audio-framework：涉及项目音频配置、ProjectAcoustics、SteamAudio 或 Sound Attenuation 时。
orion-mcp-workflow：需要连接 Unreal MCP、列出 Toolset、调用 Toolset 或验证 live Editor 时。
unreal-source-code-navigator：需要核对引擎源码、模块依赖或 MetaSound 原生节点 ClassName 时。
orion-framework-skill-authoring：修改本 Skill 或生成新的项目 Skill 时。
orion-code-style：修改 C++、Build.cs、脚本或配置文件时。

工作流

先确认目标是运行时音频逻辑、编辑器资产生成，还是 MCP 自动化。运行时逻辑不要放进 MCP Toolset；编辑器自动化放进 Editor-only 插件或 Editor Utility。
操作 MetaSound 图时优先使用 MetaSound Builder API：UMetaSoundBuilderSubsystem 创建 builder，UMetaSoundEditorSubsystem 将 builder 写入资产或打开已有资产继续编辑。
通过 MCP 操作时先调用 scripts/Test-MetaSoundMcp.ps1。只有 list_toolsets 中存在 OrionProjectToolsets.OrionMetaSoundToolset 时，才可以通过 MCP 创建或编辑 MetaSound 节点。
如果 MCP 只有 ProgrammaticToolset 或 BlueprintTools，不要用它们伪造 MetaSound 节点；当前 Programmatic 沙箱不能导入 unreal，Blueprint 图工具也不是 MetaSound 图工具。
创建节点时传显式 ClassName 三元组：Namespace、Name、Variant。标准节点常见命名空间为 UE，Wave Player 等 Engine 节点的 Variant 可能是 Mono、Stereo、5dot1 等。
编辑完成后用 DescribeAsset 读回 RootGraph、节点、接口和边数量，再保存资产。

MCP 工具

项目 MCP Toolset 名称：OrionProjectToolsets.OrionMetaSoundToolset。

核心能力：

DescribeAsset：读回 MetaSound 文档、节点、接口和边数量。
CreateSourceAsset / CreatePatchAsset：创建 MetaSound Source 或 Patch。
AddInterface：添加 MetaSound 参数接口，例如 ProjectAcoustics。
AddGraphInput / AddGraphOutput：添加图输入、输出。
AddNodeByClassName：按 FMetasoundFrontendClassName 添加原生或已注册节点。
SetNodeInputDefault、ConnectNodes、ConnectGraphInputToNode、ConnectNodeToGraphOutput、RemoveNode：基础图编辑。

验证

运行：

powershell -NoProfile -ExecutionPolicy Bypass -File .agents\skills\unreal-metasound\scripts\Test-MetaSoundMcp.ps1

需要真实创建测试资产时才加：

powershell -NoProfile -ExecutionPolicy Bypass -File .agents\skills\unreal-metasound\scripts\Test-MetaSoundMcp.ps1 -CreateProbeAsset
