If you already have the parameter definitions from recommend/schema, you may proceed straight to dryRun.

# Cinemachine Skills

Control Cinemachine Virtual Cameras and brain settings. Works with Cinemachine **2.x and 3.x** through a runtime reflection adapter (`CinemachineAdapter` / `CinemachineSkills`).

## Operating Mode

- **Approval**：查询类 skill（`cinemachine_inspect_vcam` / `cinemachine_list_components` / `cinemachine_get_brain_info`，源码标 `SkillMode.SemiAuto`）直接执行；其余配置/创建类（`cinemachine_create_vcam` / `cinemachine_set_targets` / `cinemachine_set_lens` / `cinemachine_configure_body` / `cinemachine_configure_aim` 等，标 `SkillMode.FullAuto`）需用户 grant，grant 后服务端一步执行返结果。
- **Auto / Bypass**：未被禁列表拦截的 skill 直接执行。
- 本模块**含 Delete 类 skill**：`cinemachine_set_component`（替换/移除 pipeline component）、`cinemachine_target_group_remove_member`、`cinemachine_remove_extension` 标记为 `SkillOperation.Delete`，被 `IsForbiddenInSemi` 静态拦截 —— 仅 **Bypass** 模式或加入 **Allowlist** 才能调用。
- **包依赖**：必须安装 `com.unity.cinemachine` 包（CM 2.x 或 3.x）。未安装时所有 skill 返回 `{ error = "Cinemachine is not installed. Install Cinemachine 2.x or 3.x via Package Manager." }` 的 stub —— 调用方应先用 `package_*` 系列 skill 确认安装状态。
- **反射脆弱性**：CM2 ↔ CM3 之间 API 名变化大（`CinemachineVirtualCamera` → `CinemachineCamera`，`CinemachineComponentBase` 改名等）。本模块通过 `CinemachineAdapter` 反射桥接，遇 CM 早期预览版（< `3.0.0-pre.5`）可能因 API 漂移返回失败 —— 优先用 `cinemachine_inspect_vcam` 探测当前可用字段，再决定 `propertyName`。

**DO NOT** (common hallucinations):
- `cinemachine_create` does not exist → use `cinemachine_create_vcam` for virtual cameras
- `cinemachine_set_target` / `cinemachine_set_follow` / `cinemachine_set_lookat` do not exist → use `cinemachine_set_targets` (sets both Follow and LookAt in one call)
- `cinemachine_add_brain` does not exist → CinemachineBrain is auto-added to Main Camera on first VCam creation
- Cinemachine 2.x uses `CinemachineVirtualCamera`; Cinemachine 3.x uses `CinemachineCamera` — skills handle this automatically

Additional compatibility notes:
- CM3 priority access should use `Priority.Value` as the lowest common API when writing compatibility code.
- Early CM3 previews before `3.0.0-pre.5` changed core camera APIs significantly and are outside the current support baseline.

**Routing**:
- For basic Game Camera operations → use `camera` module
- For Scene View camera → use `camera` module's `camera_set_transform`/`camera_look_at`
- For camera animation sequences → use `timeline` module with Cinemachine track

- `folder` (string): Parent folder path (default: "Assets/Settings").

### `cinemachine_inspect_vcam`
Deeply inspect a VCam, returning fields and tooltips.
**Parameters:**
- `vcamName` (string, optional): Name of the VCam GameObject.
- `instanceId` (int, optional): VCam instance ID.

- `propertyName` (string): Field or property name.
- `value` (object): New value.
- `fov` (float, optional): Lens FOV shortcut. When supplied without `propertyName`, routes to `cinemachine_set_lens`.
- `nearClip` (float, optional): Lens near clip shortcut.
- `farClip` (float, optional): Lens far clip shortcut.
- `orthoSize` (float, optional): Lens orthographic size shortcut.

### `cinemachine_set_targets`
Set Follow and LookAt targets.
**Parameters:**

- `instanceId` (int, optional): VCam Instance ID (preferred for precision).
- `path` (string, optional): VCam hierarchy path.
- `followName` (string, optional): GameObject name to follow.
- `lookAtName` (string, optional): GameObject name to look at.

### `cinemachine_set_component`
Switch VCam pipeline component (Body/Aim/Noise).
**Parameters:**
- `vcamName` (string): Name of the VCam.
- `instanceId` (int, optional): VCam Instance ID.
- `path` (string, optional): VCam hierarchy path.
- `stage` (string): "Body", "Aim", or "Noise".
- `componentType` (string): Type name (e.g. "OrbitalFollow", "Composer") or "None" to remove.

### `cinemachine_add_component`
> **DEPRECATED** — Use `cinemachine_set_component` instead for proper pipeline control (Body/Aim/Noise stages).
Add a Cinemachine component (legacy, supports CM2 and CM3).
**Parameters:**
- `vcamName` (string): Name of the VCam.
- `instanceId` (int, optional): VCam Instance ID.
- `path` (string, optional): VCam hierarchy path.
- `componentType` (string): Type name (e.g., "OrbitalFollow").

### `cinemachine_set_lens`
Quickly configure Lens settings (FOV, Near, Far, OrthoSize) and the projection ModeOverride.
**Parameters:**
- `vcamName` (string): Name of the VCam.
- `instanceId` (int, optional): VCam Instance ID.
- `path` (string, optional): VCam hierarchy path.

Case-insensitive; valid values are `None` (leave the Camera's own projection alone), `Orthographic`, `Perspective` and `Physical`. Omitting it leaves the existing `ModeOverride` untouched.

At least one of `fov` / `nearClip` / `farClip` / `orthoSize` / `mode` must be supplied; passing none returns `No values provided to update.` An invalid `mode` rejects the whole call with `SEMANTIC_INVALID` + `validValues` before anything is written, so the other parameters are not applied either.
