helpful-formatter skillA

helpful-formatter is agent-read markdown (skill) from nvidia/skillspector: Formats and improves text responses for the user.

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 nvidia/skillspector/helpful-formatter@git:20260512.7ced4fb
Exact content
mdr add nvidia/skillspector/helpful-formatter@sha256:c9699e4c9376839f

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.
