formal-verify skillA
formal-verify is agent-read markdown (skill) from vibeic/vibe-ic: Run formal property verification (FPV) on RTL by driving model-checkers such as SymbiYosys, Jasper, or VC Formal. Use when the user says "prove this", "formal verify", "model check", "run sby", or has SVA properties from assertion-gen that need to be proven or bounded..
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
mdr add vibeic/vibe-ic/formal-verify@git:20260901.2a9d213mdr add vibeic/vibe-ic/formal-verify@sha256:efa7d29c7435f76ePin 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.
