description: Wire UnityEvent persistent listeners at editor time

> **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

• Hooking up UnityEvents in the Inspector
• Wiring button or trigger callbacks
• Scripting persistent listeners
• 在 Inspector 里挂接 UnityEvent、连接按钮或触发器回调、脚本化持久监听

Event Skills

Inspect and modify persistent listeners on UnityEvents (e.g. `Button.onClick`, `Toggle.onValueChanged`) — the same listeners you see in the Inspector's event drop slots.

Operating Mode

• **Approval**：查询类 skill（`event_get_listeners` / `event_list_events` / `event_get_listener_count`，源码标 `SkillMode.SemiAuto`）直接执行；其余变更/调用类（`event_add_listener` / `event_set_listener` / `event_set_listener_state` / `event_invoke` / `event_add_listener_batch` / `event_copy_listeners`，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**：`event_remove_listener`、`event_clear_listeners` 标记为 `SkillOperation.Delete`，被 `IsForbiddenInSemi` 静态拦截 —— 仅 **Bypass** 模式或加入 **Allowlist** 才能调用。
• `event_invoke` 只在 Play mode / runtime 下有效；编辑器空跑时仅触发 EditorAndRuntime 监听。`event_add_listener` 等写入的是 persistent listener（序列化到 prefab/scene），即可在编辑器时配置。

**DO NOT** (common hallucinations):

• `event_create` / `event_trigger` do not exist → UnityEvents are declared in component source code; this module only wires listeners
• `event_subscribe` does not exist → use `event_add_listener`
• `event_remove` does not exist → use `event_remove_listener`
• `event_add_listener` requires exact component type and method name on the target

**Routing**:

• For XR interaction events → use `xr` module's `xr_add_interaction_event`
• For C# event code → write via `script` module

Skills

`event_get_listeners`

Get persistent listeners of a UnityEvent.

| Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | name | string | No | null | GameObject name | | instanceId | int | No | 0 | GameObject instance ID | | path | string | No | null | GameObject hierarchy path | | componentName | string | Yes | - | Component name | | eventName | string | Yes | - | Event field name (e.g. "onClick") |

**Returns:** `{ success, gameObject, component, eventName, listenerCount, listeners }`

`event_add_listener`

Add a persistent listener to a UnityEvent (Editor time).

| Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | name | string | No | null | GameObject name | | instanceId | int | No | 0 | GameObject instance ID | | path | string | No | null | GameObject hierarchy path | | componentName | string | Yes | - | Component owning the event | | eventName | string | Yes | - | Event field name (e.g. "onClick") | | targetObjectName | string | Yes | - | GameObject holding the method to call | | targetComponentName | string | No | null | Component on the target, or `GameObject` to call the object itself | | methodName | string | Yes | - | Public method or `set_PropertyName` | | mode | string | No | RuntimeOnly | Off, RuntimeOnly, or EditorAndRuntime | | argType | string | No | void | void, int, float, string, or bool | | floatArg | float | No | 0 | Static float argument | | intArg | int | No | 0 | Static int argument | | stringArg | string | No | null | Static string argument | | boolArg | bool | No | false | Static bool argument |

**Returns:** `{ success, message, index, mode }`

Unlike `event_set_listener`, this skill has no `object` `argType` — it only reaches the standard `UnityEvent` overloads.

`event_remove_listener`

Remove a persistent listener by index.

| Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | name | string | No | null | GameObject name | | instanceId | int | No | 0 | GameObject instance ID | | path | string | No | null | GameObject hierarchy path | | componentName | string | Yes | - | Component name | | eventName | string | Yes | - | Event field name | | index | int | No | 0 | Listener index |

**Returns:** `{ success, remainingCount }`

`event_invoke`

Invoke a UnityEvent explicitly (Runtime only).

| Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | name | string | No | null | GameObject name | | instanceId | int | No | 0 | GameObject instance ID | | path | string | No | null | GameObject hierarchy path | | componentName | string | Yes | - | Component name | | eventName | string | Yes | - | Event field name |

**Returns:** `{ success, message }`

`event_clear_listeners`

Remove all persistent listeners from a UnityEvent.

| Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | name | string | No | null | GameObject name | | instanceId | int | No | 0 | GameObject instance ID | | path | string | No | null | GameObject hierarchy path | | componentName | string | Yes | - | Component name | | eventName | string | Yes | - | Event field name (e.g. "onClick") |

**Returns:** `{ success, removed }`

`event_set_listener_state`

Set a listener's call state (Off, RuntimeOnly, EditorAndRuntime).

| Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | name | string | No | null | GameObject name | | instanceId | int | No | 0 | GameObject instance ID | | path | string | No | null | GameObject hierarchy path | | componentName | string | Yes | - | Component name | | eventName | string | Yes | - | Event field name | | index | int | No | 0 | Listener index | | state | string | No | null | Call state: "Off", "RuntimeOnly", or "E
