Adding a New LangChain Tool

If you want your agent to connect to other data sources or be able to perform custom logic, you can add a new LangChain tool to TigerGraph CoPilot.

To add a new LangChain tool, follow these steps:

In the app/tools directory, create a new file for your tool. The file should be named toolname.py where toolname is the name of your tool.
Define your tool. The tool should a valid Python class that inherits from the LangChain BaseTool class. For more information refer to the LangChain’s documentation.
Add your tool to the app/tools/init.py file. This file should contain an import statement for your tool. For example:
```
from `.generate_function` import `GenerateFunction`
```
Enable your tool to be used by the agent. To do this, import and instantiate your tool in the app/agent.py file.
For Example:
```
from tools import GenerateFunction
generate_function = GenerateFunction()
```
Then add the tool to the tools list in the Agent class.
For Example:
```
tools = [mq2s, gen_func, new_tool]
```
Test your tool. Run the service and test your tool to ensure that it works as expected.
