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 | $0.00050 | $0.01759 |
| Opus 5 | $0.00025 | $0.00879 |
| Sonnet 5 | $0.00010 | $0.00352 |
| Haiku 4.5 | $0.00005 | $0.00176 |
Grade A, and why
nextjs-16 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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 152 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Documents the critical v15→v16 breaking changes: proxy.ts replacing middleware.ts, Turbopack-only builds, use cache replacing Partial Prerendering, required React 19, and async params/searchParams. This skill covers core framework APIs only — for assembling a full production stack (Prisma, Better Auth, shadcn/ui, Zustand together) use nextjs-stack instead; for a pure React SPA without next.config.* use the react-expert skills instead.
Next.js 16 Expert
Production-ready React framework with Server Components, streaming, and Turbopack.
Agent Workflow (MANDATORY)
Before ANY implementation, use TeamCreate to spawn 3 agents:
- fuse-ai-pilot:explore-codebase - Analyze existing routes, components, and patterns
- fuse-ai-pilot:research-expert - Verify latest Next.js 16 docs via Context7/Exa
- mcp__context7__query-docs - Check breaking changes v15→v16
After implementation, run fuse-ai-pilot:sniper for validation.
Overview
When to Use
- Building new React applications with server-first architecture
- Need Server Components for optimal performance and SEO
- Implementing streaming and progressive rendering
- Migrating from Next.js 14/15 to version 16
- Using proxy.ts for route protection (replaces middleware)
- Leveraging Turbopack for faster development builds
Why Next.js 16
| Feature | Benefit |
|---|---|
| Turbopack default | 2-5x faster builds, 10x faster HMR, Webpack deprecated |
| Cache Components | Explicit caching with use cache directive |
| proxy.ts | Full Node.js runtime, replaces Edge middleware |
| React Compiler | Automatic memoization, no manual useMemo/useCallback |
| React 19 | View Transitions, useEffectEvent, Activity component |
| App Router | Nested layouts, parallel routes, intercepting routes |

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-16 is a skill published in the GitHub repository fusengine/agents (25 stars, last pushed 1mo ago), licensed MIT. It adds 50 tokens to every session and 1,759 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
