minicheck-action

Model-check every spec in a repository, in CI

Counterexamples render as diagrams in the pull request and as SARIF in the Security tab. UNDETERMINED fails the job by default.

Honest scope

Reproduced from the package README, which is the source of truth.

What a PROVED run establishes. That every reachable state of the models you wrote satisfies the invariants you declared. A model abstracts; an abstraction can hide a real defect. This checks your spec, not your implementation.

What it does not do. It does not extract specs from your code, it does not check liveness unless the spec declares a goal, and it cannot verify anything outside int-bound or max-states โ€” exceeding either yields UNDETERMINED, never a quiet pass.


Full documentation, quickstart and troubleshooting live in the repository README.
