verify skillA

verify is agent-read markdown (skill) from marcel-bich/marcel-bich-claude-marketplace: Visual verification as the Definition of Done for any change with a runtime surface (a rendered page, a UI, a live view). Use whenever you are about to call a UI or frontend change done, before moving an item to done, whenever an item is marked ui: true, or when someone asks "does it actually render / work". Proves behavior by driving the real thing in a browser and measuring computed layout - a passing pytest, a served file, a node check, or a subagent code-review is NOT proof. Applies inside s.

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 marcel-bich/marcel-bich-claude-marketplace/verify@git:20260910.43fc301
Exact content
mdr add marcel-bich/marcel-bich-claude-marketplace/verify@sha256:2276b568ae599ebf

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.
