Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00039 | $0.00521 |
| Opus 5 | $0.00019 | $0.00260 |
| Sonnet 5 | $0.00008 | $0.00104 |
| Haiku 4.5 | $0.00004 | $0.00052 |
Grade A, and why
nextjs-turbopack 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 8d 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.
This is a copy
98% identical to nextjs-turbopack — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Next.js and Turbopack
Next.js 16+ uses Turbopack by default for local development: an incremental bundler written in Rust that significantly speeds up dev startup and hot updates.
When to Use
- Turbopack (default dev): Use for day-to-day development. Faster cold start and HMR, especially in large apps.
- Webpack (legacy dev): Use only if you hit a Turbopack bug or rely on a webpack-only plugin in dev. Disable with
--webpack(or--no-turbopackdepending on your Next.js version; check the docs for your release). - Production: Production build behavior (
next build) may use Turbopack or webpack depending on Next.js version; check the official Next.js docs for your version.
Use when: developing or debugging Next.js 16+ apps, diagnosing slow dev startup or HMR, or optimizing production bundles.
How It Works
- Turbopack: Incremental bundler for Next.js dev. Uses file-system caching so restarts are much faster (e.g. 5–14x on large projects).
- Default in dev: From Next.js 16,
next devruns with Turbopack unless disabled. - File-system caching: Restarts reuse previous work; cache is typically under
.next; no extra config needed for basic use. - Bundle Analyzer (Next.js 16.1+): Experimental Bundle Analyzer to inspect output and find heavy dependencies; enable via config or experimental flag (see Next.js docs for your version).
Examples
Commands
next dev
next build
next start
Usage
Run next dev for local development with Turbopack. Use the Bundle Analyzer (see Next.js docs) to optimize code-splitting and trim large dependencies. Prefer App Router and server components where possible.
Best Practices
- Stay on a recent Next.js 16.x for stable Turbopack and caching behavior.
- If dev is slow, ensure you're on Turbopack (default) and that the cache isn't being cleared unnecessarily.
- For production bundle size issues, use the official Next.js bundle analysis tooling for your version.
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.

nextjs-turbopack is a skill published in the GitHub repository majiang213/OpenClaw-MAS (5 stars, last pushed 5mo ago), licensed MIT. It adds 39 tokens to every session and 521 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 98% identical to nextjs-turbopack, differing in 1 line, and is treated as a copy.
