deductive-verification-with-dafny-and-why3 skillA

deductive-verification-with-dafny-and-why3 is agent-read markdown (skill) from outlinedriven/outline-driven-development: Use when an imperative program needs pre-conditions, post-conditions, and loop invariants proved automatically by SMT in Dafny or Why3, short of a tactic prover..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add outlinedriven/outline-driven-development/deductive-verification-with-dafny-and-why3@git:20260912.5c5b759
Exact content
mdr add outlinedriven/outline-driven-development/deductive-verification-with-dafny-and-why3@sha256:17a181014acd8f51

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
