backend-patterns skillA
backend-patterns is agent-read markdown (skill) from affaan-m/ecc: Backend architecture patterns, API design, database optimization, and server-side best practices for Node.js, Express, and Next.js API routes..
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 affaan-m/ecc/backend-patterns@git:20260330.866d9ebmdr add affaan-m/ecc/backend-patterns@sha256:86ecf9802b5232d9Pin 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.
