You can now view and edit your node logic (such as prompts) directly within the Studio UI. See which nodes use specific assistant fields and edit them directly within node. All you have to do is tag your configuration fields with langgraph_nodes to get started.

This update allows for:

• Streamlined prompt iteration that enables users to edit and refine prompts directly within LangGraph Studio’s UI, making it easier to fine-tune agent behavior without modifying code.

• Seamless integration with LangSmith Playground, so users can experiment with different prompts and model settings in the Playground and apply changes back to their graph, reducing iteration time.

• Improved node configuration which nintroduces metadata keys that allow for precise control over which prompts are editable in the UI, enhancing customization and usability.
