Diagnosis: Why the Plan / PRD Didn't Update in the UI

I investigated why the PRD and Tasks did not appear in your Plan UI after the AI said it updated them.

Here is exactly what happened:

The UI's "Product Spec" tab specifically looks for a single document stored in your database under a hardcoded ID called prd_spec.
Because the AI doesn't have a tool specifically named update_prd_spec, it used the generic plan_vision_set tool. It saved your new PRD text into the plan.vision field (the "Objective" box) instead of the prd_spec document.
The Fix: I can either add a new AI tool specifically for updating the PRD document, or we can adjust the UI to read from the correct field.

The AI correctly executed plan_task_add for both tasks ([US1] and [US2]). I queried the Postgres database, and both tasks are successfully saved in your project's plan.
However, the Plan UI uses aggressive caching (revalidateOnFocus: false). When the AI finishes running its background tools, the UI doesn't know the database changed.
You simply need to refresh the page, and then click on the Delegate tab. You will see both [US1] and [US2] waiting in the queue!

Real-time UI: We can add a simple router.refresh() or WebSocket trigger so the Plan tab instantly updates when the AI adds a task.
Dedicated PRD Tool: I can add an update_prd_document tool to the AI so it knows exactly where to save Product Specifications.

Let me know which you want to tackle first when you're back!
