myco:vault-schema-migration skillA

myco:vault-schema-migration is agent-read markdown (skill) from goondocks-co/myco: Use this skill whenever you need to add, modify, or remove tables, columns, or indexes in the Myco vault SQLite schema — even if the user just asks to "add a column" or "create a new table." The vault uses a versioned createSchema migration chain where each schema version is a numbered step that builds on the previous one. Because user vaults accumulate real data across machines, any schema change that breaks the migration chain can corrupt or destroy vault data. This skill covers how to add a n.

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 goondocks-co/myco/myco:vault-schema-migration@git:20260801.93982a6
Exact content
mdr add goondocks-co/myco/myco:vault-schema-migration@sha256:9f13840584adfe54

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.
