Summary of ChangesHello @aibysid, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request introduces a significant enhancement to the Agent Node by adding robust support for structured JSON output. Users can now define a desired JSON schema for the agent's responses, which is then converted into a Zod schema for validation and enforcement. This feature provides greater control over the format of agent outputs, improving integration with downstream systems and ensuring predictable data structures. Highlights

Code Review
This pull request introduces structured JSON output capabilities to the Agent node, which is a great feature. The implementation correctly disables streaming when this feature is active and adds the necessary UI and backend logic to build a Zod schema from user input. My review focuses on improving the robustness and clarity of the new schema generation logic. I've identified an issue with how empty enums are handled, found an unreachable code block that should be removed, and suggest documenting a custom feature to make it usable for end-users.

I dont think it is working: I also dont think we can reuse the same logic as LLM node, because we cant have structured output and tools at the same time. If we want agent to have structured output, we probably have to do it in 2 stages:

@HenryHengZJ agreed on the two stage part , will try to raise a new PR with this approach. |
