ultracook skillA
ultracook is agent-read markdown (skill) from vanducng/skills: Open workflow conductor. Classifies a coding task and runs the smallest viable path - direct, a pipeline of named skills with checkable done-when gates, or parallel fan-out - then resumes from on-disk state. Use when the user types ultracook, asks to orchestrate, run the whole pipeline, drive a feature or fix end-to-end, or split work across agents. Composes vd: skills by name; does not reimplement them..
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 vanducng/skills/ultracook@v1.0.0mdr add vanducng/skills/ultracook@sha256:9f6293c0bce4f3a3Pin 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.
