writing-skills skillA
writing-skills is agent-read markdown (skill) from toongri/oh-my-toong-playground: Use when creating new skills, editing existing skills, or verifying skills work before deployment.
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 toongri/oh-my-toong-playground/writing-skills@git:20260731.218dcfemdr add toongri/oh-my-toong-playground/writing-skills@sha256:21991a49868db6acPin 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.
