A skill your agent uses when Storybook exists but needs an upgrade.

  • Storybook exists but needs an upgrade

What it does

Storybook Upgrade is an agent skill from sanity-io/sanity, published by the product's own GitHub organization. Use this skill when Storybook exists but needs an upgrade.

Its SKILL.md is about 110 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Frontend & Design. It works with Storybook. The repository describes itself as: Sanity Studio – Rapidly configure content workspaces powered by structured content. The licence is MIT.

When your agent uses it

  • Storybook exists but needs an upgrade

Example prompts

  • “/storybook-upgrade”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit efa15fb. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • storybook.js.org

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Storybook Upgrade loads about 111 tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 47 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~19
When it runs · the whole SKILL.md, loaded when a task matches
~111

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
