Could you build this?
Partial While prompting LLMs to generate synthetic data is simple, creating a declarative React-like DSL with a custom reconciliation tree and generation graph requires specialized compiler/DSL design.
What it would actually take: The architecture requires creating a JSX/declarative AST interpreter (or custom compiler) that schedules asynchronous LLM calls as node evaluations in a dependency DAG. It also requires batching, caching, topological sort execution, and constraint validation over structured outputs (such as instructor or Zod), necessitating compiler design and distributed task pipeline experience.
