What it does
Nextjs is an agent skill from leonvanzyl/opencode-masterclass. Next.js App Router expert guidance. Use when building, debugging, or architecting Next.js applications — routing, Server Components, Server Actions, Cache Components, layouts, middleware/proxy, data fetching, rendering strategies, and deployment on Vercel.
Its SKILL.md is about 4.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 22 other files, including reference files (for example `overlay.yaml`, `references/app-router-files.md` and `references/async-patterns.md`).
It sits in Development. It works with Next.js and Vercel.
When your agent uses it
- Architecting Next.js applications — routing
- Server Components
- Cache Components
- Middleware/proxy
Example prompts
- “/nextjs”
What it can do on your machine
Read from SKILL.md and the folder at commit 27f18e7. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Nextjs loads about 4.5k tokens when it runs, and up to ~24k if it reads all its reference files. Until then it costs about 66 tokens; SKILL.md has 375 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 375 words (~4,479 tokens).

How do I install Nextjs in Claude Code?
Run `npx skills add leonvanzyl/opencode-masterclass --skill nextjs -a claude-code`. Or copy the skill folder (.agents/skills/nextjs in leonvanzyl/opencode-masterclass) into .claude/skills/nextjs in your project. Claude Code loads it when a task matches its description.
How do I install Nextjs in Codex?
Run `npx skills add leonvanzyl/opencode-masterclass --skill nextjs -a codex`. Or copy the skill folder (.agents/skills/nextjs in leonvanzyl/opencode-masterclass) into .agents/skills/nextjs in your project. Codex loads it when a task matches its description.
Can I use Nextjs in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add leonvanzyl/opencode-masterclass --skill nextjs -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/nextjs, .gemini/skills/nextjs, .github/skills/nextjs and .opencode/skills/nextjs in your project.
What does Nextjs need to run?
SKILL.md names no scripts, command-line tools or credentials: Nextjs is instructions for the agent only.
Does Nextjs access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Nextjs safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Nextjs use?
No licence was found for Nextjs or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Nextjs use?
About 4.5k tokens (SKILL.md is roughly 18k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 20k tokens, read only when the agent opens those files.
