prompt-builder skillA

prompt-builder is agent-read markdown (skill) from marielynneblock/arcanum-artifex: Guide users through creating high-quality GitHub Copilot prompt files with clear structure, appropriate tools, validation criteria, and maintainable 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 marielynneblock/arcanum-artifex/prompt-builder@git:20260710.0115f49
Exact content
mdr add marielynneblock/arcanum-artifex/prompt-builder@sha256:8a14c33321a773f8

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.
