| Python | docs | 1 | How to add pre- and post- processing to your Agents using Python. |
Prerequisites
This tutorial assumes that you have set up Toolbox with a basic agent as described in the local quickstart.
This guide demonstrates how to implement these patterns in your Toolbox applications.
Implementation

Coming soon.
{{% /tab %}}
{{% tab header="Langchain" text=true %}}
The following example demonstrates how to use ToolboxClient with LangChain's middleware to implement pre- and post- processing for tool calls.
{{< include "python/langchain/agent.py" >}}
You can also add model-level (wrap_model) and agent-level (before_agent, after_agent) hooks to intercept messages at different stages of the execution loop. See the LangChain Middleware documentation for details on these additional hook types.

Results
The output should look similar to the following. Note that exact responses may vary due to the non-deterministic nature of LLMs and differences between orchestration frameworks.
