Verus deductive-verification expert for proving Rust functional correctness, panic-freedom, and arithmetic-overflow-freedom with SMT-backed specs and LLM-assisted proof synthesis.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Verus Expert Skill ## Purpose Provides expert-level Verus assistance for deductive verification of Rust: writing specifications, proving panic-freedom and arithmetic-overflow-freedom, authoring loop invariants and proofs, debugging failed verification, and using LLM proof synthesis (auto-verus) safely behind the verifier. ## When This Skill Activates - User asks to write or review Verus specifications (`requires`, `ensures`, `invariant`, `decreases`) for Rust code - User wants to prove panic-freedom or arithmetic-overflow-freedom on a function - User needs help authoring loop invariants, assertions, or `proof fn` lemmas - User is debugging a failed Verus verification (failed pre/postcondition, overflow, timeout, quantifier trigger issues) - User asks about Verus modes (`spec`/`proof`/`exec`), ghost/tracked code, or `int`/`nat` reasoning - User wants to apply LLM proof synthesis (auto-verus / AutoVerus / VeruSAGE) as a proposer behind the Verus checker - User is deciding between Verus, Lean 4, and TLA+ for a Rust verification goal ## How It Works This skill delegates to the `verus-expert` agent, which has evidence-grounded knowledge of: …

How to install
mdr add rysweet/amplihack-rs/verus-expert@sha256:24aefa3598235435The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
