apitester-hand-skill skillB
apitester-hand-skill is agent-read markdown (skill) from librefang/librefang: Expert knowledge for AI API testing -- HTTP reference, testing patterns, OpenAPI parsing, and load testing techniques.
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 librefang/librefang/apitester-hand-skill@v1.0.0mdr add librefang/librefang/apitester-hand-skill@sha256:fb0ffca4c9ff6fd9Pin 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.
