description: Edit Unity Animator Controllers and drive runtime parameters

> **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

• Setting up or wiring an Animator
• Adjusting animation state machines
• Driving animation parameters at runtime
• 搭建或连接 Animator、调整动画状态机、运行时驱动动画参数

Unity Animator Skills

Control Unity's Mecanim system — create Animator Controllers, add layers' states / transitions / parameters, assign controllers to GameObjects, set parameters at runtime, and play states.

Operating Mode

• **Approval**：查询类 skill（`animator_get_parameters` / `animator_get_info` / `animator_list_states`，源码标 `SkillMode.SemiAuto`）直接执行；其余变更类（create_controller / add_parameter / set_parameter / play / assign_controller / add_state / add_transition，标 `SkillMode.FullAuto`）需用户 grant，grant 后服务端一步执行返结果。
• **Auto / Bypass**：所有 skill 直接执行；Auto 走 AI 自我评估，Bypass 全放行。
• 本模块**不含** Delete / PlayMode / Reload / 高危 skill，无 Bypass-only 拦截项。
• `animator_set_parameter` / `animator_play` 作用于场景中已挂 Animator 的 GameObject；如果当前不在 Play mode，状态机只在 Editor 预览模式推进，效果与 runtime 不完全等价。

**DO NOT** (common hallucinations):

• `animator_create_clip` / `animator_add_clip` do not exist → AnimationClips are created via Unity Editor or asset import
• `animator_set_speed` does not exist → use `component_set_property` on Animator component with propertyName="speed"

**Routing**:

• For Timeline animation → use `timeline` module
• For component properties on Animator → use `component` module
• For animation import settings → use `importer` module

Skills

animator_create_controller

Create a new Animator Controller.

| Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | `name` | string | Yes | - | Controller name | | `folder` | string | No | "Assets/Animations" | Save folder |

**Returns**: `{success, name, path}`

animator_add_parameter

Add a parameter to a controller.

| Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | `controllerPath` | string | Yes | - | Controller asset path | | `paramName` | string | Yes | - | Parameter name | | `paramType` | string | Yes | - | float/int/bool/trigger | | `defaultFloat` | float | No | 0 | Initial float value | | `defaultInt` | int | No | 0 | Initial int value | | `defaultBool` | bool | No | false | Initial bool value |

animator_get_parameters

Get all parameters from a controller.

| Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `controllerPath` | string | Yes | Controller asset path |

**Returns**: `{controller, parameters: [{name, type, defaultFloat, defaultInt, defaultBool}]}`

animator_set_parameter
