data-migration skillA

data-migration is agent-read markdown (skill) from okhp3/skillz: Changes a schema or moves data in production without downtime or loss — column changes, backfills, table splits, and system-to-system moves. Use this whenever the user is writing a migration, altering a table, backfilling data, renaming a column, or moving data between systems. Treat it as required reading before any migration runs against a database with real data. For designing the schema, use data-modeling..

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 okhp3/skillz/data-migration@git:20260828.866dec6
Exact content
mdr add okhp3/skillz/data-migration@sha256:2a33c8fae2b6dfae

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.
