awesome-copilot-example copilot-instructions.md

Project instructions for building web applications with Next.js, TypeScript, and Tailwind CSS. Next.js is a React framework, TypeScript checks code types, and Tailwind CSS provides utility-based styling.

In plain words
What is it for?
They help create or review Next.js applications using server and client components, typed code, forms, loading and error states, database access, dark mode, and responsive layouts.
Why use it?
They give the coding agent consistent rules for page structure, data loading, validation, accessibility, security, and responsive design.

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.

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

awesome-copilot-example copilot-instructions.md 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 2d 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

Next.js + Tailwind Development Instructions

Instructions for high-quality Next.js applications with Tailwind CSS styling and TypeScript.

Project Context

  • Latest Next.js (App Router)
  • TypeScript for type safety
  • Tailwind CSS for styling

Development Standards

Architecture

  • App Router with server and client components
  • Group routes by feature/domain
  • Implement proper error boundaries
  • Use React Server Components by default
  • Leverage static optimization where possible

TypeScript

  • Strict mode enabled
  • Clear type definitions
  • Proper error handling with type guards
  • Zod for runtime type validation

Styling

  • Tailwind CSS with consistent color palette
  • Responsive design patterns
  • Dark mode support
  • Follow container queries best practices
  • Maintain semantic HTML structure

State Management

  • React Server Components for server state
  • React hooks for client state
  • Proper loading and error states
  • Optimistic updates where appropriate

Data Fetching

  • Server Components for direct database queries
  • React Suspense for loading states
  • Proper error handling and retry logic
  • Cache invalidation strategies

Security

  • Input validation and sanitization
  • Proper authentication checks
  • CSRF protection
  • Rate limiting implementation
  • Secure API route handling

Performance

  • Image optimization with next/image
  • Font optimization with next/font
  • Route prefetching
  • Proper code splitting
  • Bundle size optimization

Implementation Process

  1. Plan component hierarchy
  2. Define types and interfaces
  3. Implement server-side logic
  4. Build client components
  5. Add proper error handling
  6. Implement responsive styling
  7. Add loading states
  8. Write tests

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.
