invariant-spec-tests skillA
invariant-spec-tests is agent-read markdown (skill) from infinite-system/ivue: How to write a check that proves something — a test is a SPEC: the generator expressed for this implementation. Covers the spec discipline (one test per component or caveat, name = property, annotation = claim, specs grow while defects stay flat) and the assertion rules — smokes, probes, matrix rows, regression tests. Complements drive-pty (how to DRIVE) and the invariants skill (which owns the generator header form). Use when authoring or reviewing any test, smoke, harness probe, or verificatio.
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 infinite-system/ivue/invariant-spec-tests@git:20260825.35ea5admdr add infinite-system/ivue/invariant-spec-tests@sha256:1e9957b47ef68ec3Pin 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.
