feature-verify skillA

feature-verify is agent-read markdown (skill) from arcasilesgroup/ai-engineering: Cross-verify a just-finished feature with throwaway browser tests driven by chrome-headless-shell — proves the feature actually does what it was supposed to do, and proves the change didn't break the routes and components that depend on it. Reports a verdict with evidence and never edits app code. Use this whenever a feature, fix, refactor, or UI change has just been completed — including when the user says "done", "that's implemented", "verify this", "does it work?", "make sure nothing broke", .

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 arcasilesgroup/ai-engineering/feature-verify@git:20260911.eccaa3a
Exact content
mdr add arcasilesgroup/ai-engineering/feature-verify@sha256:22bc92109ce286d0

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.
