# Function: executeFromRegistry()

```ts
function executeFromRegistry(
   registry: ToolRegistry, 
   name: string, 
   args: unknown, 
signal?: AbortSignal): Promise<unknown>;

```

Validates tool-call arguments against the entry's schema and invokes its handler. On validation failure, returns an LLM-friendly error string (matching the behavior of `tool()`) rather than throwing, so the model can self-correct on its next turn.
