Partial An AI can scaffold a parser and a TypeScript CLI, but a correct TLA+ interpreter and model checker requires precise formal semantics and efficient state-space exploration that vibe coding alone is unlikely to get right.
What it would actually take: Write a parser for the TLA+ grammar, an evaluator for its set, function, and temporal semantics, and a breadth-first or DFS state-space model checker with invariant and liveness checking. The hard parts are faithfully matching TLA+ semantics and making state exploration tractable, which benefits from formal-methods expertise and differential testing against the reference TLC checker.
