phase-validate skillA

phase-validate is agent-read markdown (skill) from yarlson/yarstack: Validate exactly one implemented phase or scoped change against its authoritative contract. Use after implementation to re-derive criterion-level conclusions from current evidence and fix only required implementation gaps..

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

Latest version
mdr add yarlson/yarstack/phase-validate@git:20260720.2e4f3b4
Exact content
mdr add yarlson/yarstack/phase-validate@sha256:88d918da7471cf62

Pin 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.
