Could you build this?

Partial Building an interactive CLI wrapper is easy, but integrating type-safe constrained AST generation that guarantees syntactically and semantically valid TypeScript code requires compiler-level formal grammar handling.

What it would actually take: The CLI would interface with an LLM backend using TypeScript compiler API (ts-morph / @babel/parser) and grammar-constrained decoding (such as Guidance, Outlines, or custom BNF grammars). The complex component is ensuring the model outputs strictly adhere to AST node schemas and existing codebase typings in real time without generating invalid syntax trees.
