## 1. Prepare the Tool Provider yaml
### Introduction
This yaml declares a new tool provider, and includes information like the provider's name, icon, author, and other details that are fetched by the frontend for display.
### Example

- The `identity` field is mandatory, it contains the basic information of the tool provider, including author, name, label, description, icon, etc.
- The icon needs to be placed in the `_assets` folder of the current module, you can refer to [here](../../provider/builtin/google/_assets/icon.svg).
- The `tags` field is optional, it is used to classify the provider, and the frontend can filter the provider according to the tag, for all tags, they have been listed below:

Google, as a third-party tool, uses the API provided by SerpApi, which requires an API Key to use. This means that this tool needs a credential to use. For tools like `wikipedia`, there is no need to fill in the credential field, you can refer to [here](../../provider/builtin/wikipedia/wikipedia.yaml).
After configuring the credential field, the effect is as follows:
```yaml

author: Dify

- `type`: Credential field type, currently can be either `secret-input`, `text-input`, or `select` , corresponding to password input box, text input box, and drop-down box, respectively. If set to `secret-input`, it will mask the input content on the frontend, and the backend will encrypt the input content.
## 3. Prepare Tool yaml
A provider can have multiple tools, each tool needs a yaml file to describe, this file contains the basic information, parameters, output, etc. of the tool.
Still taking GoogleSearch as an example, we need to create a `tools` module under the `google` module, and create `tools/google_search.yaml`, the content is as follows.

## 4. Add Tool Logic
After completing the tool configuration, we can start writing the tool code that defines how it is invoked.

### Parameters
The overall logic of the tool is in the `_invoke` method, this method accepts two parameters: `user_id` and `tool_parameters`, which represent the user ID and tool parameters respectively
### Return Data
When the tool returns, you can choose to return one message or multiple messages, here we return one message, using `create_text_message` and `create_link_message` can create a text message or a link message.
## 5. Add Provider Code
Finally, we need to create a provider class under the provider module to implement the provider's credential verification logic. If the credential verification fails, it will throw a `ToolProviderCredentialValidationError` exception.
Create `google.py` under the `google` module, the content is as follows.

## Completion
After the above steps are completed, we can see this tool on the frontend, and it can be used in the Agent.
Of course, because google_search needs a credential, before using it, you also need to input your credentials on the frontend.
