# Function: runToolGate()

```ts
function runToolGate(
  gate: ToolGateFn | undefined,
  ctx: unknown,
  tool: string,
  args: unknown,
): Promise<void>;
```

Defined in: [src/batteries/tools/\_shared/index.ts:288](https://github.com/NHTIO/ADK/blob/v1.20260713.1/src/src/batteries/tools/_shared/index.ts#L288)

Await a configured [ToolGateFn](../type-aliases/ToolGateFn.md) (no-op when absent). Factory batteries call this at
the top of their handlers so the gate runs before any side effect.
