Before calling any skill in this module: if you are about to call a skill with parameters guessed from its name or description, STOP — read this file (or fetch its schema via GET /skills/recommend?includeSchema=true) first. If you already have the parameter definitions from recommend/schema, you may proceed straight to dryRun.

Triggers

• Creating or tuning Cinemachine cameras
• Configuring follow/look-at/noise
• Building cinematic camera behavior
• 创建或调校 Cinemachine 相机、设置跟随/注视/噪声、构建运镜效果

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

• orthoSize (float, optional): Lens orthographic size shortcut.

cinemachine_set_targets

Set Follow and LookAt targets. Parameters:

• 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.

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.
