# sanity-studio-upgrade The skill inspects your repo and reports only the breaking changes that actually apply to it. Handy when your Studio sits several majors behind. - skill · `type=skill` · Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode · 524 installs · ★ 194 - Author: sanity-io - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/sanity-io/agent-toolkit/tree/HEAD/skills/sanity-studio-upgrade/SKILL.md - Updated: 2026-10-23 - HTML: https://affpapa.org/en/nevibecode/skills/sanity-studio-upgrade ## What it does It starts by reading the installed versions, config and source in the current repository, then checks the npm registry and the sanity.io docs. What comes back is an upgrade plan for Sanity Studio listing just the breaking changes your code will hit. The full changelog between two versions already exists, and it is not much use to someone in the middle of an upgrade. The skill is read-only. It inspects files, runs read-only shell commands such as `npm view`, and may unpack a tarball into a temporary directory outside the project to look at type declarations. It will not run `pnpm install`, `npm install` or `npm ci`, because those rewrite the lockfile. If you want to know what a dependency tree will look like after a change, the report hands you `pnpm install --lockfile-only` as a command to run yourself. Version numbers never come from memory. Current state is read from the lockfile, targets come from a live registry query, and every recommended version is checked for an actual publish before it lands in the report. Studio v2 is out of scope: the v2 to v3 boundary rewrites the config and plugin layer rather than bumping a dependency, so those projects get identified and redirected. Network access to the npm registry and sanity.io docs is required. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add sanity-io/agent-toolkit --skill sanity-studio-upgrade -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/sanity-studio-upgrade/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/sanity-studio-upgrade/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add sanity-io/agent-toolkit --skill sanity-studio-upgrade -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/sanity-studio-upgrade/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add sanity-io/agent-toolkit --skill sanity-studio-upgrade -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/sanity-studio-upgrade/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install sanity-io/agent-toolkit sanity-studio-upgrade ``` 2. **Manually: put the files in place** - File: `.github/skills/sanity-studio-upgrade/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add sanity-io/agent-toolkit --skill sanity-studio-upgrade -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/sanity-io/agent-toolkit --path skills/sanity-studio-upgrade ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/sanity-studio-upgrade/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add sanity-io/agent-toolkit --skill sanity-studio-upgrade -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/sanity-io/agent-toolkit/tree/HEAD/skills/sanity-studio-upgrade/SKILL.md ## When to use it - see which breaking changes hit your Studio when you cross a major version - find out how far behind your repo is on the `sanity` package - work out why the Studio broke after a package bump - cut the changelog down to the changes that apply to your code - collect the questions only a human on the team can answer ## Example prompts - produce an upgrade plan for the Sanity Studio in this repo - what breaks if we bump the `sanity` package? - our studio is on an old version — how far behind are we? ## Source text · SKILL.md · MIT Below is the content of a third-party file.

BEGIN THIRD-PARTY FILE cd3081daec8abf68 ```text --- name: sanity-studio-upgrade description: 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 upgrade, or asks how far behind their Studio is. Triggers on "upgrade sanity studio", "migrate our studio to v6", "bump sanity", "what breaks if we upgrade", "our studio is on an old version", "sanity upgrade plan", "is our studio out of date", "we are several majors behind". DO NOT load for upgrading non-Sanity dependencies, for Content Lake `apiVersion` questions, for content or schema migrations that change documents, or for setting up a new Sanity project. compatibility: Requires network access to the npm registry and sanity.io docs for version and changelog lookups --- # 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. ``` END THIRD-PARTY FILE cd3081daec8abf68 The third-party file has ended.
