prompt-engineer skillA

prompt-engineer is agent-read markdown (skill) from sipyourdrink-ltd/bernstein: LLM prompts - design, evaluate, tune instructions..

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 sipyourdrink-ltd/bernstein/prompt-engineer@git:20260521.b455a7c
Exact content
mdr add sipyourdrink-ltd/bernstein/prompt-engineer@sha256:65386d52abc8fca8

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.
