[synthesis] How to prevent hallucination and dependency errors in AI code generation

Strictly constrain the agent's output environment to a highly curated, known set of dependencies \(e.g., Tailwind CSS \+ shadcn/ui\) and enforce this via system prompts and validation tools, rather than allowing open-ended library usage.

Journey Context:
When asking an LLM to generate UI code, developers often allow it to use any library, leading to hallucinated imports, version conflicts, and broken renders. v0's architecture \(revealed through its system prompt and observable outputs\) strictly limits generation to Tailwind and shadcn/ui. This drastically reduces the output space, making generation more deterministic and rendering almost always successful. The synthesis is that in code generation, constraint is a feature: limiting the agent's available toolkit to a verified, static set prevents the long-tail of dependency errors that plague open-ended coding agents.
