preview-screens skillA
preview-screens is agent-read markdown (skill) from microsoft/power-platform-skills: Use when the user wants to preview generated screens in a browser without starting Metro / a simulator — for example after /create-mobile-app finishes or after /edit-app regenerates a screen..
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 microsoft/power-platform-skills/preview-screens@git:20260907.ff74919mdr add microsoft/power-platform-skills/preview-screens@sha256:a6342f9cf61e5dafPin 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.
