hello skillB

hello is agent-read markdown (skill) from kyure-a/agent-skills-nix: Contains a symlink that intentionally resolves outside its declared source root..

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 kyure-a/agent-skills-nix/hello@git:20260810.1594ba4
Exact content
mdr add kyure-a/agent-skills-nix/hello@sha256:d36bfd4f451898ea

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.
