vertical-slice skillA

vertical-slice is agent-read markdown (skill) from etr/groundwork: Use when building a feature large enough to span multiple layers - structure the work as thin, end-to-end, independently-shippable slices behind a feature flag instead of building layer-by-layer.

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 etr/groundwork/vertical-slice@git:20260622.3609064
Exact content
mdr add etr/groundwork/vertical-slice@sha256:24ec0e5836d9645b

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.
