prd-writing skillA
prd-writing is agent-read markdown (skill) from vm0-ai/vm0-skills: Draft PRDs with problem framing, users, requirements, acceptance criteria, scope, and measurable outcomes..
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 vm0-ai/vm0-skills/prd-writing@git:20260709.c4cfc48mdr add vm0-ai/vm0-skills/prd-writing@sha256:2e31073c32293484Pin 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.
