credential-manager skillA
credential-manager is agent-read markdown (skill) from betterwright/betterwright: Read this before any login, signup, password change, or checkout so the right credential source is used in the right order without ever exposing a secret..
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 betterwright/betterwright/credential-manager@git:20260719.dbff053mdr add betterwright/betterwright/credential-manager@sha256:f751c8b4e6f2b70dPin 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.
