db-migration skillA

db-migration is agent-read markdown (skill) from byerlikaya/claude-starter-kit: Apply schema migrations safely: detect the tool, classify the change by risk, gate destructive ones behind approval, back up in prod, preview-apply-verify, roll back on failure. Use when a schema change is about to be applied to any environment..

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 byerlikaya/claude-starter-kit/db-migration@git:20260826.c9e7ffc
Exact content
mdr add byerlikaya/claude-starter-kit/db-migration@sha256:0bed15bd799b32fa

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.
