safe-migrations skillA

safe-migrations is agent-read markdown (skill) from prabhdeepsingh/claude-plugins: Zero-downtime schema and data migration discipline — expand → migrate → contract, never destructive in the release that ships the code, backfills as jobs, every step reversible. INVOKE PROACTIVELY when creating or editing a migration in any framework, writing ALTER TABLE / index / enum / constraint changes, planning a backfill, or shipping code and schema together. Not for greenfield schema design ([[code-standards]]) or diagnosing a broken migration ([[debugging]])..

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 prabhdeepsingh/claude-plugins/safe-migrations@git:20260825.06c64c5
Exact content
mdr add prabhdeepsingh/claude-plugins/safe-migrations@sha256:8f8759eea3cc2715

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.
