+In many scenarios, the raw inputs, outputs, or schemas of actions may benefit from additional processing. This refinement step can significantly improve the quality and usability of your data. Here are three key use cases:
 
-- **Postprocessing**: Streamline large action responses by filtering or formatting the data before it reaches the Language Model (LLM).
 - **Preprocessing**: Generate or modify inputs dynamically at runtime, handling scenarios that may be challenging for the LLM to produce directly.
+- **Postprocessing**: Streamline large action responses by filtering or formatting the data before it reaches the Language Model (LLM).
+- **Schema Processing**: Modify the request schema to include additional fields or alter existing ones.
