nextjs

nextjs is a cursor rule for Cursor from hlalljie/agent-workflow-presets. It costs 0 tokens per session (90 once invoked), scanned A, original, MIT.

A rule for checking the version-specific guidance bundled with Next.js, a framework for building web applications, before writing code. It also calls attention to breaking changes and deprecated features.

In plain words
What is it for?
Use it before adding or changing Next.js code, especially when the project may differ from earlier versions.
Why use it?
It reduces mistakes caused by applying advice from an older Next.js version. The agent can follow the documentation that matches the project.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

nextjs scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

This project uses Next.js [VERSION] which may have breaking changes from earlier versions. Before writing Next.js code, check node_modules/next/dist/docs/ for the bundled guides. Heed deprecation notices.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
