## 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.
**Parameters:**
- `name` / `instanceId` / `path`: Target GameObject locator.
- `componentName` (string): Component name.
- `eventName` (string): Event field name (e.g. "onClick").

### `event_add_listener`
Add a persistent listener to a UnityEvent (Editor time).
**Parameters:**
- `name` / `instanceId` / `path`, `componentName`, `eventName`: Target event.
- `targetObjectName`, `targetComponentName`, `methodName`: Method to call.
- `mode` (string, optional): "RuntimeOnly", "EditorAndRuntime", "Off".
- `argType` (string, optional): "void", "int", "float", "string", "bool".
- `floatArg`, `intArg`, `stringArg`, `boolArg`: Argument value if needed.

### `event_remove_listener`
Remove a persistent listener by index.
**Parameters:**
- `name` / `instanceId` / `path`, `componentName`, `eventName`: Target event.
- `index` (int): Listener index.

### `event_invoke`
Invoke a UnityEvent explicitly (Runtime only).
**Parameters:**
- `name` / `instanceId` / `path`, `componentName`, `eventName`: Target event.
