Drafts and verifies formal Dafny specifications from natural language to ensure algorithmic correctness.
This skill enables developers to bridge the gap between natural language requirements and rigorous formal methods. It iteratively drafts, tests, and refines Dafny specifications—including preconditions, postconditions, and invariants—to create a verified mathematical contract for your code. By assessing the 'verification value' of a task and proactively warning about architectural limitations like I/O or concurrency, it ensures that high-stakes logic is logically sound before implementation begins.
