Report #21460

[synthesis] Agent generates UI code with arbitrary libraries, resulting in inconsistent and broken interfaces

Constrain the agent's output vocabulary to a specific, well-tested component library \(like shadcn/ui \+ Tailwind\) and enforce these constraints in the system prompt and tool schemas.

Journey Context:
General-purpose LLMs struggle with cohesive UI from scratch because the solution space is too large. v0's success comes from constraining the output to React \+ Tailwind \+ shadcn/ui. This reduces the search space, increases the likelihood of syntactically correct code, and makes the output predictable and composable.
