## Summary by CodeRabbit

* **New Features**
* Document and code artifact generation tools now use a single prompt
field for user input, enabling more flexible content creation powered by
AI.

* **Bug Fixes**
* Improved error handling for missing prompt templates or providers
during document and code artifact generation.

* **Refactor**
* Simplified input schemas for document and code artifact tools,
consolidating multiple input fields into a single prompt.
* Output schemas updated to remove metadata and other unused fields for
a cleaner result.
