demo-review skillA

demo-review is agent-read markdown (skill) from lukaskellerstein/claude-my-marketplace: Quality-checks a rendered demo video before it ships — extracts frames, grades each section against its successCriteria, and finds spinners, empty states, clipped text, exposed secrets, audio/video desync, and pacing problems. Use after a draft render, before a final render, or when asked whether a demo video is good enough to ship..

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 lukaskellerstein/claude-my-marketplace/demo-review@git:20260912.b2c10cb
Exact content
mdr add lukaskellerstein/claude-my-marketplace/demo-review@sha256:449b19f9b5010af5

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.
