Produces a tailored Sanity Studio upgrade plan by inspecting the repository's installed versions, config, and source, then reporting only the breaking changes that actually apply. Covers Studio v3 and later; v2 projects are identified and redirected, not planned. Use this skill whenever someone wants to upgrade, migrate, or modernize a Sanity Studio across one or more major versions from v3 onward, asks what will break if they bump the `sanity` package, asks why their Studio broke after an…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Sanity Studio upgrade planner

Generate an upgrade plan for the Sanity Studio in the current repository.

The plan's value is **subtraction**. A list of every breaking change between two versions already exists; it is called the changelog, and it is not useful to someone mid-upgrade. This skill produces the much shorter list of changes that apply to *this* repository, plus the questions only a human can answer.

## Three rules that determine whether the output is trustworthy

**1. Never state a version number from memory. Look it up, and confirm it exists.**

Package versions change weekly. Every version in the report must come from either the repository's lockfile (for current state) or a live registry query (for targets). If a lookup is not possible, say so in the report rather than guessing. A plan that names a stale "latest" is worse than no plan, because the reader will act on it.

There is a second, worse version of this failure: a version number that was never published at all, arrived at by assuming one package tracks another's numbering. That one fails at install. Any version you are about to describe as "lockstep" or "matches core" needs an existence check first.

How to install

The exact contents, by fingerprint
mdr add sanity-io/agent-toolkit/sanity-studio-upgrade@sha256:08f0e18abf480570

The line at the top of this page pins the label git:20260909.e5c04f4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
