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 | $0.01086 |
| Opus 5 | $0.00025 | $0.00543 |
| Sonnet 5 | $0.00010 | $0.00217 |
| Haiku 4.5 | $0.00005 | $0.00109 |
Grade A, and why
nextjs-stack 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 — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Documents forbidden substitutions (NextAuth.js instead of Better Auth, Pages Router instead of App Router, React Hook Form instead of TanStack Form, Client-Components-by-default instead of Server-first) and provides reference material for stack-decision justification, SOLID module structure, cross-part integration points, and project bootstrapping. Does not cover core framework API details like routing internals, caching, or proxy.ts — those live in nextjs-16.
Next.js Complete Stack
Master skill combining all framework documentation for modern Next.js development.
Agent Workflow (MANDATORY)
Before ANY implementation, use TeamCreate to spawn 3 agents:
- fuse-ai-pilot:explore-codebase - Analyze project structure and existing patterns
- fuse-ai-pilot:research-expert - Verify latest docs for all stack technologies
- mcp__context7__query-docs - Check integration compatibility
After implementation, run fuse-ai-pilot:sniper for validation.
Overview
When to Use
- Starting a new Next.js 16 project from scratch
- Need the complete recommended technology stack
- Building production applications with authentication
- Implementing forms, state management, and UI components
- Understanding how all parts fit together
Technology Stack
| Layer | Technology | Skill Reference |
|---|---|---|
| Framework | Next.js 16 (App Router) | nextjs-16 |
| Database ORM | Prisma 7 | prisma-7 |
| Authentication | Better Auth 1.2 | better-auth |
| UI Components | shadcn/ui 3.8.0 | nextjs-shadcn |
| Forms | TanStack Form | nextjs-tanstack-form |
| State | Zustand | nextjs-zustand |
| Styling | Tailwind CSS 4 | tailwindcss |
| i18n | next-intl 4.0 | nextjs-i18n |
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-stack 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 1,086 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.
Other skills, from other repositories
radin-record
Log feedback, bugs, follow-ups, or ideas raised mid-session as structured backlog entries, so they survive past the conversation. Use for /radin-record, "log this to the backlog", "add as follow-up/bug/idea", "record what we just found", "note this for later", "add findings to backlog". Triggers even on vague asks…
radin-doctor
Check that radin's own install under /.claude is complete and its optional companion tools are reachable. Use for /radin-doctor, "check my radin install", "is radin installed correctly", "radin doctor", "verify radin install".
designing-interfaces
Creates a design system for software with a UI. Use when a project has a user interface and architecture is confirmed — whether creating from scratch or extracting patterns from existing code.
managing-product
Extracts product requirements and produces a PRD. Use when a user wants to build software and needs to define what to build before architecture or implementation, when scoping an MVP, or when translating a vague idea into a buildable specification.
orchestrating-software-dev
Runs software development projects from idea to completion. Use when starting a software project, adding a feature, fixing a bug, or resuming an in-progress build.
collecting-sources
Collects research sources with quality evaluation. Use when gathering or finding sources, building a source library, searching for academic papers, or performing RADAR assessment.
