- Full validation only occurs at `toolcall_end` when arguments are complete
- The Google provider does not support function call streaming. Instead, you will receive a single `toolcall_delta` event with the full arguments.
### Provider tool-call validation
By default, providers validate streamed tool calls against your tool schema and abort the stream on validation errors. Set `validateToolCallsAtProvider: false` on `stream`, `streamSimple`, `complete`, `completeSimple`, or `AgentLoopConfig` to skip provider-level validation and let downstream code (for example, `agentLoop` via `executeToolCalls` → `validateToolArguments`) surface schema errors as `toolResult` messages. This enables the model to retry after receiving a validation error.
```typescript
await streamSimple(model, context, {
apiKey: 'your-key',
validateToolCallsAtProvider: false
});
```
- `true` (default): Provider validates tool calls and emits an error if arguments do not match the schema
- `false`: Provider emits tool calls even when arguments are invalid; callers must validate and handle errors themselves
