michael-denyer/agent-formal-verifySkill
Model-check thread protocols with TLA+ and TLC, prove sequential invariants with Lean 4, and check bounded Rust functions with Kani. Map counter-examples to source locations, reproductions and fixes, and keep the models in CI. Use for /agent-formal-verify:formal-verify, formal verification, model checking, Lean proofs, Kani, bounded Rust verification, or concurrency bugs that runtime tests cannot reproduce.
Why this score
This repo hosts 2 skills, so its 17 stars are split between them (about 9 each) for scoring.
Popularity score: 58/100 from public GitHub signals only. It shows how widely used and maintained this is, not how well it works. Not included yet: the fake-star check. The security scan is shown separately and doesn't change the score. How we rank

What its code does:
- Runs shell commands Common for dev tools. Read the commands it runs.scripts/lean-check.sh:28, scripts/setup.sh:10, scripts/tlc-matrix.sh:25 and 8 more
A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
