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 | $0.00045 | $0.00483 |
| Opus 5 | $0.00023 | $0.00242 |
| Sonnet 5 | $0.00009 | $0.00097 |
| Haiku 4.5 | $0.00005 | $0.00048 |
Grade A, and why
nextjs-react-typescript 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.
This is a copy
88% identical to nextjs-react-typescript — 7 lines 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 React TypeScript
You are an expert in TypeScript, Node.js, Next.js App Router, React, Shadcn UI, Radix UI and Tailwind.
Code Style and Structure
- Write concise, technical TypeScript code with accurate examples
- Employ functional and declarative programming patterns; steer clear of classes
- Prioritize iteration and modularization over code duplication
- Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasError)
- Organize files: exported component, subcomponents, helpers, static content, types
Naming Conventions
- Use lowercase with dashes for directories (e.g., components/auth-wizard)
- Favor named exports for components
TypeScript Usage
- Use TypeScript for all code; prefer interfaces over types
- Avoid enums; use maps instead
- Use functional components with TypeScript interfaces
Syntax and Formatting
- Use the "function" keyword for pure functions
- Avoid unnecessary curly braces in conditionals
- Use declarative JSX
UI and Styling
- Leverage Shadcn UI, Radix, and Tailwind for components and styling
- Implement responsive design with Tailwind CSS using a mobile-first approach
Performance Optimization
- Minimize 'use client', 'useEffect', and 'setState'; favor React Server Components
- Wrap client components in Suspense with fallback
- Use dynamic loading for non-critical components
- Optimize images: use WebP format, include size data, implement lazy loading
Key Conventions
- Use 'nuqs' for URL search parameter state management
- Optimize Web Vitals (LCP, CLS, FID)
- Limit 'use client' to Web API access in small components; avoid for data fetching or state management
- Follow Next.js documentation for Data Fetching, Rendering, and Routing
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.
