# 🛠️ Configure Tools

> Learn how to configure tools

## Initialization Parameters

When setting up Composio tools, you might need to provide various configuration parameters like API keys, session IDs, or custom settings. These parameters can be specified at two levels:

1. **App-level**: Parameters that apply to all actions within a specific tool/app
2. **Action-level**: Specific parameters needed for individual actions

For example, if you're using the Image Analyzer tool, you'll need to provide an OpenAI API key. Similarly, other tools might require their own specific configuration parameters to function properly.

<Steps>
  <Step title="Install required libraries">
    ```bash Python
    pip install langchain langchain-openai composio-langchain
    ```
  </Step>

  <Step title="Import required libraries">
    <CodeGroup>
      ```python Python
      from langchain.agents import create_openai_functions_agent, AgentExecutor
      from langchain import hub
      from langchain_openai import ChatOpenAI
      from composio_langchain import ComposioToolSet, Action, App
      ```

    </CodeGroup>
  </Step>

  <Step title="Import Prompt template & Initialize ChatOpenAI & composio toolset client">
    During the initialization of the `ComposioToolSet` client, we can add metadata to actions & apps. In this example, we're adding an OpenAI API key for the `IMAGE_ANALYSER_ANALYSE` action:

    <CodeGroup>
      ```python Python {5-9}
      prompt = hub.pull("hwchase17/openai-functions-agent")

      llm = ChatOpenAI()
      composio_toolset = ComposioToolSet(
          metadata={
              Action.IMAGE_ANALYSER_ANALYSE: {
                  "OPENAI_API_KEY": "<your-openai-api-key>",
              }
          }
      )
      ```

      ```javascript JavaScript
      Coming Soon
      ```
    </CodeGroup>
  </Step>

  <Step title="Get Image Analyser Action from Composio">
    <CodeGroup>
      ```python Python
      tools = composio_toolset.get_tools(
          actions=[Action.IMAGE_ANALYSER_ANALYSE],
      )
      ```

      ```javascript JavaScript
      Coming Soon
      ```
    </CodeGroup>
  </Step>

  <Step title="Invoke the agent">
    <CodeGroup>
      ```python Python
      task = "Describe the image. Image Path: cat.png"

      agent = create_openai_functions_agent(llm, tools, prompt)
      agent_executor = AgentExecutor(agent=agent, tools=tools, verbose=True)

      agent_executor.invoke({"input": task})
      ```

      ```javascript JavaScript
      Coming Soon
      ```
    </CodeGroup>
  </Step>
</Steps>

### How to add metadata at App-level?

Above we saw how to add metadata at the Action-level. Here's an example of how to add metadata at the App-level:

<CodeGroup>
  ```python Python
  toolset = ComposioToolSet(
      metadata={
          App.<app_name>: {
              "attribute": "value",
          }
      }
  )
  ```
