database skillA
database is agent-read markdown (skill) from jnpiyush/agentx: Design database operations including migrations, indexing strategies, transactions, connection pooling, and ORM best practices. Use when creating database schemas, writing migrations, optimizing slow queries, configuring connection pools, or choosing between ORM frameworks..
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.

mdr add jnpiyush/agentx/database@v1.0.0mdr add jnpiyush/agentx/database@sha256:fe7f37b9047ebc68Pin 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.
