What it does
Next Upgrade is an agent skill from vercel-labs/openreview, published by the product's own GitHub organization. Upgrade Next.js to the latest version following official migration guides and codemods
Its SKILL.md is about 500 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 Development, covering Code migrations. It works with Next.js, Vercel and npm. The repository describes itself as: An open-source, self-hosted AI code review bot powered by Vercel.
When your agent uses it
- Tasks that involve Code migrations
Example prompts
- “/next-upgrade”
Requirements
- Node.js
Workflow steps
8 steps, taken from the first numbered list in SKILL.md.
- Detect current version: Read package.json to identify the current Next.js version and related dependencies (React, React DOM, etc.)
- Fetch the latest upgrade guide: Use WebFetch to get the official upgrade documentation
- Determine upgrade path: Based on current version, identify which migration steps apply. For major version jumps, upgrade incrementally…
- Run codemods first: Next.js provides codemods to automate breaking changes
- Update dependencies: Upgrade Next.js and peer dependencies together
- Review breaking changes: Check the upgrade guide for manual changes needed
- Update TypeScript types (if applicable)
- Test the upgrade
What it can do on your machine
Read from SKILL.md and the folder at commit 672deb2. 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:
npmnpx
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):
nextjs.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
Next Upgrade loads about 502 tokens when it runs. Until then it costs about 25 tokens; SKILL.md has 175 words of instructions outside code blocks.
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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 175 words (~502 tokens).
