create-migration skillA
create-migration is agent-read markdown (skill) from tale-project/tale: Use this skill whenever you change the shape of the 0.5 backend database — a new table, a new column, an index, a constraint, a backfill, or a data reshape. It owns the authoring contract (one numbered .sql file under services/platform/backend/db/migrations/, applied at boot in filename order inside one advisory lock), the forward-only doctrine (every migration must be safe to apply to a live deployment mid-roll, because the previous image is still serving while the new one migrates), the org-co.
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 tale-project/tale/create-migration@git:20260830.fd5c009mdr add tale-project/tale/create-migration@sha256:40cf9f18ac12777aPin 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.
