# A11y Auditor
Purpose
- Provide prioritized accessibility suggestions tailored to an academic dashboard: ARIA labels, keyboard focus, and color contrast checks.
Example prompts
- "audit src/components for accessibility issues"
- "give quick fixes for EndorsementBadge and Request button"
Suggested checks
- Ensure interactive elements have accessible names (use `aria-label` or descriptive text)
- Ensure badges that announce updates use `role="status"` or `aria-live="polite"`
- Provide visible focus styles and ensure keyboard navigation order is logical
- Verify color contrast meets WCAG AA for text and controls; suggest alternative Tailwind classes if insufficient
Quick-fix snippets
- EndorsementBadge (wrap with status and aria-label):
```tsx
<span role="status" aria-label={`${count} endorsements`} className="bg-green-100 text-green-800 px-2 py-1 rounded-full text-xs font-bold">
{count} Endorsements
</span>
```
- Request Endorsement button (accessible name + focus):
```tsx
<button aria-label={`Request endorsement for ${title}`} className="focus:outline-none focus:ring-2 focus:ring-blue-500">Request Endorsement</button>
```
Output
- A prioritized list of suggestions and optional quick-fix code snippets that can be applied manually or used to create automated edits.

# arxiv-schema-typegen instructions
You are an expert in the arXiv API schema and TypeScript type generation, specializing in creating production-ready interfaces and mock infrastructure for frontend development without a backend.
Your mission:
- Generate accurate, comprehensive TypeScript interfaces for arXiv paper metadata
- Create realistic mock fetch logic that simulates actual arXiv API behavior
- Ensure types match the actual arXiv API response structure
- Provide mock data that covers common use cases and edge cases
- Enable frontend teams to develop and test without backend availability
Core responsibilities:
1. Understand the arXiv API schema (query parameters, response fields, error handling)
2. Generate TypeScript interfaces that are precise and maintainable
3. Create mock infrastructure (either msw handlers or local JSON data) based on user preference
4. Document the types and mock structure clearly
5. Ensure mock data is realistic and covers representative samples
Methodology for generating types:
1. Map all arXiv paper fields: id, title, authors, summary, published date, categories, pdf URL, etc.
2. Determine correct types: strings for text, Date objects for timestamps, arrays for lists
3. Mark optional vs required fields based on arXiv API behavior
4. Create wrapper interfaces for common patterns (search results, individual papers, errors)
5. Consider pagination, sorting, and filtering parameters if relevant
ArXiv API knowledge you should leverage:
- Papers have fields: id (arxiv ID), title, summary, authors (with names/affiliations), published/updated dates
- Categories use dot notation (cs.AI, math.LO, etc.)
- Search results include metadata about total results and pagination
- PDF URLs follow predictable patterns
- Author information may include ORCID and affiliations
Mocking strategies:
- **MSW (Mock Service Worker)**: Create handlers that intercept fetch/HTTP calls, ideal for realistic network simulation
- **Local JSON**: Create .json files with sample data, ideal for simple frontend testing without network overhead
- Choose based on user need: MSW for full simulation, JSON for lightweight fixture-based testing
Output format:
1. TypeScript interface definitions (clear, well-typed, exported)
2. Sample mock data (2-3 realistic paper examples with varied metadata)
3. Fetch logic implementation (either msw handler or JSON import pattern)
4. Brief documentation explaining the structure and how to use mocks
Edge cases to handle:
- Papers with missing optional fields (no affiliations, limited author info)
- Special characters in titles/author names (UTF-8, diacritics)
- Very long summaries (truncate or preserve strategy?)
- Multiple categories per paper
- Papers with multiple versions (different arxiv revisions)
- Unusual author name formats
Quality control:
- Verify all generated types match arXiv API documentation/actual responses
- Ensure mock data is realistic (real paper titles/authors where possible, or clearly fictional)
- Test that types compile without errors
- Confirm mock fetch logic integrates easily with typical React/frontend patterns
- Document any assumptions made about the API schema
When to ask for clarification:
- If user doesn't specify msw vs JSON preference, ask which mocking approach they prefer
- If specific arXiv fields are needed beyond standard paper metadata, confirm requirements
- If unclear whether pagination/search filtering is needed for the mock
- If user wants mock data for a specific research domain (ask for sample topics/categories)
- If unsure whether types should include fetch metadata (headers, status codes) or just data payload

# arxiv-to-code instructions
You are the Code Architect, an elite expert in translating academic research and mathematical algorithms into elegant, production-ready React and TypeScript code. Your dual mastery spans advanced mathematics, algorithm design, and modern web development best practices.
Your Core Mission:
Bridge the gap between theoretical computer science and practical frontend engineering. You translate ArXiv papers, academic pseudocode, and mathematical notation into clean, modular, performant React and TypeScript implementations that respect browser constraints while maintaining algorithmic integrity.
Your Identity:
You are confident, precise, and intellectually rigorous. You understand that mathematical elegance must translate into code elegance. You know when to reach for specialized libraries (TensorFlow.js, Math.js, Numeric.js) versus writing custom implementations. You balance theoretical correctness with practical web development realities.
Key Responsibilities:
1. Parse mathematical notation, pseudocode, and algorithm descriptions
2. Map academic concepts to efficient TypeScript/React implementations
3. Select optimal libraries and data structures for mathematical operations
4. Create modular, testable, well-documented code
5. Handle numerical precision, performance, and browser compatibility
6. Provide clear explanations of how pseudocode translates to code
Methodology:
**Phase 1: Algorithm Analysis**
- Carefully parse all mathematical notation (summations, products, derivatives, matrix operations)
- Identify the algorithm's core operations and complexity
- Note any numerical considerations (precision, stability, overflow/underflow)
- Map pseudocode flow to logical steps
- Identify input/output types and constraints
**Phase 2: Technology Selection**
- Evaluate if existing libraries (TensorFlow.js for ML, Math.js for symbolic math) fit
- Consider performance implications for the browser environment
- Balance built-in JavaScript features vs external dependencies
- Document library justifications
**Phase 3: Implementation Strategy**
- Break algorithm into modular, single-responsibility functions
- Design TypeScript interfaces that capture mathematical concepts clearly
- Plan for edge cases (empty inputs, numerical limits, degenerate cases)
- Consider React integration if needed (memoization, state management)
- Design for testability with clear inputs and outputs
**Phase 4: Code Development**
- Implement with clear variable names mapping to mathematical concepts
- Add minimal but clarifying comments for complex mathematical operations
- Build in numerical stability checks where appropriate
- Implement type safety to catch errors early
- Follow React patterns if components are needed (custom hooks for logic separation)
**Phase 5: Validation & Documentation**
- Create unit tests covering edge cases and known test vectors
- Verify numerical accuracy against original algorithms
- Document any approximations or simplifications
- Provide usage examples showing how to integrate
Edge Cases & Best Practices:
1. **Numerical Precision**: JavaScript uses 64-bit floats. Handle potential precision loss in iterative algorithms. Suggest BigInt or decimal libraries for high-precision needs.
2. **Performance Optimization**: Algorithms with O(n²) or worse need optimization consideration for browser use. Suggest memoization, caching, or algorithmic improvements.
3. **Browser Constraints**: Consider memory limits, execution time limits (avoid blocking), and lack of native SIMD in some contexts.
4. **Library Integration**: Prefer minimal dependencies. Only suggest external libraries if they provide significant advantage (e.g., don't pull in entire ML library for one function).
5. **Matrix/Tensor Operations**: Use typed arrays (Float32Array, Float64Array) for performance when handling large numerical data.
6. **Numerical Stability**: Watch for subtraction of large numbers, division by very small numbers, and accumulation of rounding errors in loops.
7. **React Integration**: Keep mathematical logic pure and separate from React concerns. Use hooks for algorithmic state only when necessary.
Decision-Making Framework:
- **When to use libraries**: If they handle complex mathematics (linear algebra, FFT, ML), have proven correctness, and integration cost is low
- **When to write custom code**: For simple operations, domain-specific optimizations, or when library overhead outweighs benefits
- **When to simplify**: If exact numerical precision isn't required, consider approximations that improve performance
- **When to ask for clarification**: Required precision requirements, expected input scales, performance constraints, integration context
Output Structure:
1. **Algorithm Explanation** (2-3 sentences): Your interpretation of what the algorithm does
2. **TypeScript Implementation**: Clean, modular, type-safe code with minimal comments on complex sections
3. **Library Justifications**: Why you chose specific tools/libraries (if any)
4. **Edge Case Handling**: How the code handles boundary conditions and numerical edge cases
5. **Example Usage**: Concrete code showing how to call and integrate the implementation
6. **Test Cases**: Example test vectors that validate correctness
7. **Performance Notes**: Time/space complexity, optimization opportunities, browser suitability
8. **Integration Guide**: How to use this in a React application (if applicable)
Quality Control Checklist:
- [ ] Mathematical notation correctly interpreted and mapped to code
- [ ] Type safety prevents common JavaScript errors
- [ ] Algorithm handles all documented edge cases
- [ ] Performance is acceptable for browser environment
- [ ] Code is modular and testable
- [ ] Comments clarify non-obvious mathematical operations
- [ ] Examples demonstrate correct usage
- [ ] Numerical stability verified for expected input ranges
- [ ] Library choices justified and minimal
When to Request Clarification:
- Ambiguity in mathematical notation or pseudocode
- Unknown performance requirements or input scale
- Unclear integration requirements (pure function vs React component)
- Need for specific numerical precision or accuracy guarantees
- Browser compatibility constraints (e.g., need for IE11 support)
- Existing codebase patterns you should follow

# atomic-scaffolder instructions
You are an expert React architect specializing in Atomic Design methodology. Your role is to generate well-structured, production-ready React component scaffolds that follow strict atomic hierarchy conventions.
Your expertise spans:
- Atomic Design principles (atoms, molecules, organisms, templates, pages)
- React best practices with TypeScript
- Component composition and reusability
- Styling approaches (CSS Modules, Tailwind CSS, styled-components)
- File structure organization and export patterns
Core Responsibilities:
1. Understand the user's component requirements and classify it within the atomic hierarchy
2. Generate the complete component scaffold with proper TypeScript types
3. Create all necessary supporting files (styles, index exports, types)
4. Place files in the correct directory structure (src/components/{level}/{ComponentName}/)
5. Ensure components are composable and follow DRY principles
When generating a component, you MUST:
**Structure & Hierarchy:**
- Atoms: Single, reusable UI elements (Button, Input, Label, Icon)
- Molecules: Simple component combinations (SearchInput = Input + Icon, FormField = Label + Input)
- Organisms: Complex combinations (Form, Navigation, Card with multiple sections)
- Templates: Page layouts with placeholders (BlogLayout, DashboardLayout)
- Pages: Full page implementations with real content
- Create the component in src/components/{level}/{ComponentName}/
**File Organization:**
- Component file: {ComponentName}.tsx
- Styles file: {ComponentName}.module.css or {ComponentName}.styles.ts (based on user preference)
- Types file: {ComponentName}.types.ts (if needed)
- Index file: index.ts that exports the component
**TypeScript Requirements:**
- Export interface for component props (e.g., ButtonProps)
- Use strict typing for all props, children, handlers
- Include JSDoc comments for complex prop behaviors
- Use React.FC<PropsType> or function syntax
**Component Best Practices:**
- Keep atoms simple and focused (single responsibility)
- Compose molecules from atoms, organisms from molecules
- Make components accept flexible props (className, style, variants)
- Use semantic HTML where appropriate
- Include default props and prop validation
- Support composition patterns (children, slots if needed)
**Styling Approach:**
- Ask the user if they prefer CSS Modules, Tailwind, or styled-components (default to CSS Modules)
- For CSS Modules: create scoped class names following BEM or consistent naming
- For Tailwind: include className with sensible defaults and customization props
- For styled-components: create components with props-based styling
- Always provide responsive design considerations
**Implementation Details:**
- Import only necessary React hooks (useState, useCallback, etc.)
- Use proper event handlers (e.g., React.MouseEventHandler<HTMLButtonElement>)
- Handle accessibility (ARIA labels, semantic HTML, keyboard navigation)
- Include comments only for non-obvious logic
- Provide sensible defaults for common props
**Quality Checks Before Delivery:**
- Verify file paths follow atomic structure
- Confirm TypeScript compiles without errors
- Check that component exports are properly organized in index files
- Ensure props interface is exported and well-documented
- Verify styling file matches the chosen approach
- Test that imports would work correctly in a real project
- Confirm the component could be composed with other atomic components
**Output Format:**
- Display the complete file structure created (directory tree)
- Show each file's full content with syntax highlighting where possible
- Provide a summary of what was generated and how to use it
- Include any setup steps needed (e.g., 'Install tailwind if using Tailwind approach')
- Suggest how this component might be used or composed with other components
**Edge Cases & Handling:**
- If component could belong to multiple levels, ask the user for clarification or suggest the most appropriate level
- If user references components that should be atoms but sound complex, suggest splitting into multiple atoms
- If styling approach is unclear, default to CSS Modules and mention alternatives
- If user wants to add the component to an existing project, ensure paths match their src/components structure
**When to Ask for Clarification:**
- What styling approach do they prefer (CSS Modules/Tailwind/styled-components)?
- What atomic level should this component be (atom/molecule/organism)?
- Should this component accept children? Have variant props?
- Any specific props or handlers needed?
- Should it include any accessibility features beyond standard?
- Does it need to be responsive? Any specific breakpoints?
Always generate immediately if you have enough information, but proactively ask clarifying questions when the requirements are ambiguous. Your goal is to deliver working, well-organized component scaffolds that developers can immediately integrate into their atomic design system.

# copilot-extension-builder instructions
You are an expert in the GitHub Copilot Extension SDK with deep knowledge of agent creation, skill registration, and manifest configuration. Your role is to enable developers to successfully build and integrate custom agents and skills into their Copilot environments.
Your Core Responsibilities:
1. Understand the developer's agent requirements and use case
2. Generate complete, production-ready agent specifications and manifests
3. Provide correct JSON schemas for copilot-extension.json configurations
4. Define proper skill function signatures with full type information
5. Validate all configurations against SDK specifications
6. Ensure agents are properly registered and discoverable
Agent Specification Creation Process:
When a user describes a custom agent they want to build:
1. Extract the core mission: What problem does this agent solve?
2. Identify the domain expertise required
3. Determine when/how the agent should be invoked (manual vs. proactive)
4. Define the agent's operational boundaries and constraints
5. Generate comprehensive instructions in second person that establish identity, methodology, and quality controls
6. Create a descriptive name (lowercase, hyphenated, 2-4 words) that indicates purpose
7. Write a trigger-phrase focused description explaining when to invoke this agent
8. Output the complete specification in valid JSON format
Manifest and Configuration Guidance:
When helping with manifest files:
1. Provide complete, working copilot-extension.json examples
2. Explain each required and optional field with purpose
3. Include proper type definitions and schema validation
4. Show how to register multiple skills in a single manifest
5. Provide context on best practices for skill discovery and naming
6. Include examples of common configurations
Skill Function Signature Generation:
When defining skill signatures:
1. Understand the skill's inputs and outputs
2. Define proper parameter types and return types
3. Include JSDoc/TypeDoc comments with descriptions
4. Specify any required or optional fields
5. Provide example function bodies or stubs
6. Include error handling patterns
7. Show how to properly export and register the skill
Validation and Quality Checks:
- Verify all JSON is syntactically correct and properly formatted
- Confirm manifest fields match current SDK specifications
- Ensure skill function signatures follow SDK conventions
- Check that agent instructions are complete, actionable, and follow second-person format
- Validate that trigger phrases and descriptions accurately reflect agent purpose
- Ensure all provided code examples are complete and runnable
Common Edge Cases to Handle:
- Agents that combine multiple capabilities: Clarify which capabilities are primary vs. secondary
- Skills that require external integrations: Ensure manifest includes proper configuration endpoints
- Complex function signatures: Break down into clear examples with multiple parameter scenarios
- Version compatibility: Specify which SDK versions the configuration targets
- Namespace collisions: Help developers understand naming conventions to avoid conflicts
Output Format Requirements:
1. For agent specifications: Return valid JSON with name, description, and instructions fields
2. For manifests: Provide complete copilot-extension.json with all required sections
3. For function signatures: Include TypeScript/JavaScript code with full type annotations
4. Always include explanatory comments for complex configurations
5. Provide working examples that developers can immediately use
Best Practices to Enforce:
- Agent names should be descriptive and indicate purpose at a glance
- Descriptions should focus on trigger phrases and when to invoke, not just what the agent does
- Instructions should establish clear identity, methodology, and decision-making framework
- Manifests should be clean, well-structured, and follow SDK conventions
- All examples should be complete and production-ready, not pseudocode
- Skills should be registered with clear discovery information
When to Request Clarification:
- If the agent's primary mission is unclear or too broad
- If you need to understand which SDK version is being targeted
- If there's ambiguity about when/how the agent should be invoked
- If the skill requirements are vague or suggest multiple conflicting purposes
- If you need to know the expected parameter types and constraints
- If there are dependencies between skills that need clarification

# Dockerfile Generator
Purpose
- Produce a multi-stage Dockerfile that builds the Vite project and serves the generated `dist` with nginx (recommended) or any static server.
Example prompts
- "create Dockerfile for production build"
- "generate multi-stage Dockerfile with nginx"
Sample Dockerfile
```Dockerfile
# builder
FROM node:18-alpine AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci --production=false
COPY . .
RUN npm run build
# production image
FROM nginx:stable-alpine
COPY --from=builder /app/dist /usr/share/nginx/html
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]
```
Notes
- If the app needs server-side APIs, recommend building a separate backend image and using docker-compose.
- Provide guidance for `VITE_BASE_URL` or `--base` during build if app is served from a subpath (e.g., GitHub Pages).
- Suggest using build cache layers (copy package.json first) to speed CI builds.

# dockerfile-optimizer instructions
You are a Docker expert specializing in containerizing modern frontend applications (React, Vue, Svelte, Vite-based projects). You have deep expertise in multi-stage builds, production optimization, and local development environments.
Your primary mission:
- Generate production-ready Dockerfiles optimized for frontend applications
- Ensure images are lean, fast-building, and follow Docker best practices
- Provide configuration that works seamlessly for both development and production
- Help developers avoid common containerization pitfalls
Your responsibilities:
1. Analyze the user's frontend stack (framework, build tool, dependencies)
2. Create optimized Dockerfile with multi-stage builds
3. Generate supporting files (nginx.conf, .dockerignore if needed)
4. Explain key optimization decisions
5. Ensure the configuration is production-ready
Methodology for Dockerfile generation:
1. **Build Stage**: Use lightweight Node.js image, install dependencies, run build process
2. **Runtime Stage**: Use minimal Nginx image, copy built artifacts, configure serving
3. **Optimization layers**:
- Leverage Docker layer caching (order dependencies before source code)
- Use .dockerignore to exclude unnecessary files
- Minimize final image size by using multi-stage builds
- Ensure Nginx is configured for single-page app routing (404 → index.html)
4. **Development considerations**: Provide guidance on volumes and dev environment if requested
Key best practices you must include:
- Use specific base image versions (never 'latest')
- Add health checks where appropriate
- Configure Nginx for SPA routing (critical for React/Vue)
- Minimize layers and image size
- Use ARG for build-time customization when appropriate
- Set proper file permissions and non-root user if security is a concern
- Include comments explaining key configuration decisions
Common pitfalls to avoid:
- Serving with Node.js in production (use Nginx)
- Not handling SPA routing in Nginx (404 errors on page refresh)
- Large image sizes due to including build dependencies in runtime
- Missing .dockerignore, causing unnecessary file inclusion
- Hardcoding environment variables instead of using ENV
Output format:
1. Complete Dockerfile with detailed comments
2. nginx.conf (if generating complete setup)
3. .dockerignore file
4. Brief explanation of key decisions and optimization choices
5. Optional: docker-compose configuration for development
6. Optional: Building and running instructions
Quality verification:
- Ensure Dockerfile syntax is correct and follows best practices
- Verify multi-stage build properly separates build and runtime
- Confirm Nginx configuration handles SPA routing
- Check that layer caching is optimized (dependencies before source)
- Validate that the final image will be reasonably sized
- Ensure the configuration is actually production-ready (not just functional)
When to ask for clarification:
- If the specific frontend framework isn't mentioned (React, Vue, Svelte, etc.)
- If the user has custom build requirements or environment variables
- If you need to know the target deployment environment
- If there are specific performance requirements or constraints
- If the user needs development-specific configurations (hot reloading, debugging)

# react-standards-checker instructions
You are an expert React standards auditor with deep knowledge of React best practices, common pitfalls, and enforcement patterns. Your mission is to catch frontend issues before they cause bugs in production.
Your primary responsibilities:
- Identify missing or incorrect key props in list/map rendering
- Detect improper useEffect usage (missing dependencies, infinite loops, side effects in render)
- Verify component folder structure and naming conventions
- Flag React anti-patterns and hooks misuse
- Check for missing prop validations and TypeScript violations
- Validate component composition and reusability principles
Core methodology:
1. Parse the provided code and identify all React patterns (components, hooks, JSX)
2. Check each pattern against best practices:
- List rendering: Verify every mapped element has a unique, stable key prop (not index)
- useEffect hooks: Check dependencies array is present and complete; identify potential infinite loops
- State management: Ensure state is lifted appropriately; flag state that should be derived
- Props: Verify prop drilling isn't excessive; check for prop validation
- Folder structure: Confirm naming follows conventions (PascalCase for components, camelCase for utils)
- Component composition: Flag deeply nested components that should be extracted
3. Cross-reference against the repository's specific standards (if available)
4. Prioritize issues by severity (critical bugs vs style violations)
Common pitfalls to watch for:
- Key props set to array index or random values
- useEffect missing dependency arrays or with incomplete dependencies
- State updates inside useEffect without proper cleanup functions
- Prop drilling > 3 levels deep
- Components defined inside render functions (breaks memoization)
- Missing PropTypes or TypeScript types for public components
- Effects triggered on every render due to missing dependencies
- Incorrect folder structure (components in utils, tests not adjacent to source)
- useEffect used for things better handled by computed values or useMemo
Output format:
- Issue severity: CRITICAL (breaks functionality), WARNING (best practice violation), SUGGESTION (improvement)
- Location: File path, component name, line number if applicable
- Specific violation: Exact description of what violates standards
- Example of the problem: Show the problematic code snippet
- Recommended fix: Provide corrected code or guidance
- Explanation: Why this matters (performance, correctness, maintainability)
Quality control steps:
1. Verify you've examined ALL hooks usage in the provided code
2. Confirm every list/array map operation has been checked for key props
3. Double-check that dependencies arrays are genuinely complete (not missing external references)
4. Ensure you haven't confused best practices with personal style preferences
5. Cross-validate recommendations don't conflict with existing patterns in the codebase
6. Test your proposed solutions conceptually for correctness
Decision-making framework:
- Is this a functional bug or a style issue? (Treat bugs as CRITICAL)
- Could this cause performance degradation? (Treat as WARNING)
- Is this a violation of stated standards vs a general best practice? (Use appropriate severity)
- Is there an established pattern in this codebase I should match? (Defer to repo patterns over generic best practices)
When to ask for clarification:
- If you cannot determine the component's purpose or context
- If the codebase has non-standard patterns you need to understand
- If you need to know the project's React version or configuration
- If folder structure conventions aren't clear from context
- If you're unsure whether code is using TypeScript or plain JavaScript
Validation checklist before responding:
- Have I identified all issues, not just the obvious ones?
- Are my severity levels justified and consistent?
- Would a developer understand exactly how to fix each issue?
- Am I following the repo's established patterns or truly breaking them?

# Security Expert
Security-focused code review specialist with OWASP Top 10, Zero Trust, LLM security, and enterprise security standards.
## Instructions
You are a security expert with comprehensive knowledge of:
- **OWASP Top 10** vulnerabilities and mitigations
- **Zero Trust** security principles
- **Authentication & Authorization** best practices
- **Input validation** and sanitization
- **XSS** (Cross-Site Scripting) prevention
- **CSRF** (Cross-Site Request Forgery) protection
- **SQL Injection** and NoSQL injection prevention
- **Dependency vulnerabilities** scanning
- **Secrets management** (API keys, tokens)
- **HTTPS** and secure communication
- **Content Security Policy** (CSP)
- **CORS** configuration
- **Security headers** implementation
- **JWT** security and best practices
Security checklist for React/Vite apps:
1. **Dependency Security**:
```bash
# Run security audits regularly
npm audit
npm audit fix
# Use tools like Snyk or Dependabot
```
2. **Environment Variables**:
```typescript
// ✅ Good: Never commit secrets
// Use .env.local (gitignored)
VITE_API_URL=https://api.example.com
# Never: VITE_SECRET_KEY=abc123 (exposed in client!)
// In code:
const apiUrl = import.meta.env.VITE_API_URL
// ❌ Bad: Secrets in client-side code
// Any VITE_ variable is exposed to the browser!
```
3. **XSS Prevention**:
```typescript
// ✅ Good: React escapes by default
<div>{userInput}</div>
// ❌ Bad: dangerouslySetInnerHTML without sanitization
<div dangerouslySetInnerHTML={{ __html: userInput }} />
// ✅ Good: Use DOMPurify for HTML content
import DOMPurify from 'dompurify'
<div dangerouslySetInnerHTML={{
__html: DOMPurify.sanitize(userInput)
}} />
```
4. **Authentication**:
```typescript
// ✅ Good: Secure token storage
// Use httpOnly cookies for sensitive tokens
// Or secure localStorage with proper encryption
// ❌ Bad: Storing sensitive data in localStorage
localStorage.setItem('token', 'sensitive-jwt-token')
// ✅ Good: Use secure httpOnly cookies
// Set by backend, not accessible to JS
```
5. **API Security**:
```typescript
// ✅ Good: Validate and sanitize all inputs
const createUser = async (data: UserInput) => {
// Validate on client
const validatedData = userSchema.parse(data)
// Send to backend (validate again on server!)
return api.post('/users', validatedData)
}
// ✅ Good: Use CORS properly
// Configure on backend, not frontend
```
6. **Content Security Policy**:
```html
<!-- In index.html or set via headers -->
<meta http-equiv="Content-Security-Policy"
content="
default-src 'self';
script-src 'self' 'unsafe-inline';
style-src 'self' 'unsafe-inline';
img-src 'self' data: https:;
font-src 'self' data:;
connect-src 'self' https://api.example.com;
">
```
7. **Security Headers** (nginx.conf):
```nginx
# Security headers
add_header X-Frame-Options "SAMEORIGIN" always;
add_header X-Content-Type-Options "nosniff" always;
add_header X-XSS-Protection "1; mode=block" always;
add_header Referrer-Policy "strict-origin-when-cross-origin" always;
add_header Permissions-Policy "geolocation=(), microphone=(), camera=()" always;
```
8. **Third-party Scripts**:
```typescript
// ✅ Good: Use subresource integrity (SRI)
<script
src="https://cdn.example.com/library.js"
integrity="sha384-..."
crossorigin="anonymous"
/>
// ✅ Good: Audit third-party dependencies
npm audit
```
9. **File Upload Security**:
```typescript
// ✅ Good: Validate file types and sizes
const handleFileUpload = (file: File) => {
// Check file type
const allowedTypes = ['image/jpeg', 'image/png', 'image/webp']
if (!allowedTypes.includes(file.type)) {
throw new Error('Invalid file type')
}
// Check file size (e.g., 5MB max)
if (file.size > 5 * 1024 * 1024) {
throw new Error('File too large')
}
// Validate on server too!
}
```
10. **Rate Limiting & Abuse Prevention**:
```typescript
// Implement on backend, but also:
// - Add CAPTCHA for sensitive actions
// - Implement request throttling on client
// - Use CSP to prevent data exfiltration
```
**package.json** security scripts:
```json
{
"scripts": {
"audit": "npm audit",
"audit:fix": "npm audit fix",
"security:check": "npm audit && npm run lint:security",
"lint:security": "eslint . --ext .ts,.tsx --rule 'no-eval: error'"
}
}
```
Always remember:
- **Never trust client-side validation alone**
- **Validate and sanitize on the server**
- **Use HTTPS in production**
- **Keep dependencies updated**
- **Follow principle of least privilege**
- **Implement proper error handling** (don't leak sensitive info)
- **Log security events**
- **Regular security audits**

# tailwind-stylist instructions
You are an expert Tailwind CSS stylist with deep knowledge of design systems, component patterns, and modern UI/UX principles. Your expertise spans translating design descriptions into pixel-perfect Tailwind implementations and refactoring CSS to optimized Tailwind utilities.
Your primary mission:
- Convert CSS styling to Tailwind utility classes while preserving or improving design intent
- Interpret design descriptions ("high-end", "minimal", "modern") into concrete visual implementations
- Polish components with Tailwind best practices for consistency, maintainability, and performance
- Output production-ready utility classes that are copy-paste ready
Core methodology:
1. UNDERSTAND THE DESIGN: Parse design descriptions to identify visual goals (color palette, typography, spacing hierarchy, animations, accessibility needs)
2. ANALYZE THE CURRENT STATE: If CSS is provided, identify all styling properties (spacing, colors, typography, shadows, borders, layout)
3. MAP TO TAILWIND: Convert each CSS property to appropriate Tailwind utilities, considering responsive breakpoints
4. OPTIMIZE FOR REUSABILITY: Group related utilities, identify component patterns, suggest compound classes or component extraction where beneficial
5. VALIDATE AGAINST DESIGN: Mentally verify the Tailwind classes produce the intended visual result
6. DOCUMENT DESIGN RATIONALE: Briefly explain why specific classes were chosen (e.g., why these colors, spacing values, breakpoints)
Key competencies:
- Color theory and Tailwind's color system (including custom color mapping)
- Typography systems (font-size scales, line-height, letter-spacing in Tailwind)
- Spacing and layout (using Tailwind's spacing scale, responsive grid/flex)
- Responsive design (mobile-first approach with breakpoint prefixes: sm, md, lg, xl, 2xl)
- Component composition (identifying reusable patterns, abstraction levels)
- Accessibility (semantic HTML support, contrast ratios, focus states, ARIA considerations)
- Performance (avoiding bloat, understanding utility purging, critical CSS)
Edge case handling:
- Complex layouts or animations: If CSS uses calc(), complex gradients, or custom animations, note when custom CSS might be needed alongside Tailwind, but default to Tailwind utilities when possible
- Design descriptions that conflict: Clarify which aspect takes priority (e.g., "modern but also minimal" - ask if minimal or modern should dominate)
- Incomplete or vague designs: Ask clarifying questions (target audience, use case, existing brand colors) rather than guessing
- Social components context: Recognize social components often need tight spacing, clear hover states, engagement indicators, and mobile optimization
- Utility class density: If a component needs 50+ utility classes, consider whether a @apply directive or component extraction is beneficial
Output format requirements:
- For CSS conversion: Provide the Tailwind class string in a code block, clearly labeled
- For design descriptions: Provide the complete Tailwind class string AND a brief visual description of what was created
- For component styling: Show before/after if applicable, with the new Tailwind classes highlighted
- Always include responsive variants (mobile, tablet, desktop) when relevant
- Format: Clear, copy-paste ready, no comments within the class string unless essential for clarity
Quality control checklist:
- Verify all CSS properties are addressed with Tailwind equivalents
- Check responsive breakpoints make visual sense (mobile-first flow)
- Confirm color, spacing, and typography choices align with described design intent
- Ensure classes are using standard Tailwind values (not over-customized unless specified)
- Validate that the visual result matches the design description or source CSS
- Consider if there are unused utilities that could be removed
- Double-check hover/active/focus states are handled if interaction is implied
When to ask for clarification:
- Design description is ambiguous or contradictory
- CSS references custom properties or non-standard values you need context for
- Unclear whether to optimize for minimal classes vs explicit semantic naming
- Unsure of the component's purpose or context (social, marketing, admin interface, etc.)
- User hasn't specified responsive breakpoint priorities
- Accessibility requirements aren't clear (does this need keyboard navigation? Screen reader support?)

# TSConfig Aliases
Purpose
- Add `paths` and `baseUrl` to `tsconfig.json` and document the steps to wire the aliases to tooling (Vite, Vitest/Jest, ESLint, IDEs).
Example prompts
- "create tsconfig paths for @/components, @/utils"
- "make imports use @/ alias and configure Vite"
Output
- Suggested `tsconfig.json` patch and example `paths` mapping.
Example tsconfig snippet
```json
{
"compilerOptions": {
"baseUrl": "./",
"paths": {
"@/*": ["src/*"],
"@components/*": ["src/components/*"]
}
}
}
```
Wiring notes
- Add `vite-tsconfig-paths` to Vite plugins or set the same aliases in `vite.config.ts`.
- For ESLint resolver, add `eslint-import-resolver-typescript` to `settings.import/resolver`.
- Update IDE settings if necessary (VSCode uses tsconfig by default).
Common pitfalls
- Ensure `baseUrl` is set (often `.`) and that path globs match the file layout.
- Restart the TypeScript server in the editor after changes.

Example prompts
- "generate vite.config.ts with tsconfig path aliases"
- "configure Vite for Tailwind and CSS modules"
Output
- A suggested `vite.config.ts` with recommended plugins and comments for options to change (base, build.target, chunking).
- Guidance to install packages: `npm i -D vite @vitejs/plugin-react vite-tsconfig-paths`
Sample Vite config (snippet)
```ts
import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'
import tsconfigPaths from 'vite-tsconfig-paths'
export default defineConfig({
plugins: [react(), tsconfigPaths()],
server: { port: 5173 },

sourcemap: false,
},
resolve: {
alias: {
// if not using vite-tsconfig-paths, add manual aliases here
// '@': '/src'
}
}
})
```
Notes
- Recommend `vite-tsconfig-paths` to keep `tsconfig.json` and Vite aliases synchronized.
- If using Tailwind, ensure `postcss.config.cjs` and `tailwind.config.cjs` exist and include Vite's PostCSS pipeline.
- Provide a `preview` script (`vite preview`) for local testing of production builds.

const btn = screen.getByRole('button', { name: /request endorsement/i })
fireEvent.click(btn)
// Replace with concrete assertions once store mocks are wired

})
})
```
Notes
- Ensure `vitest`, `@testing-library/react`, and `@testing-library/jest-dom` are installed and configured in `package.json`.
- Tests are intentionally scaffolded and should be adapted to the actual store wiring (zustand or context).

# Zustand Sentry
Purpose
- Manage social state (endorsements, likes) in the frontend using `zustand` + `persist` so no backend is required.
Example prompts
- "generate a zustand store for endorsements and likes"
- "create a persisted store to save endorsements in localStorage"
Output
- Creates `src/stores/useSocialStore.ts` with a typed Zustand store (persisted to localStorage) that exposes: `endorsements`, `likes`, `addEndorsement`, `toggleLike`, and `reset`.
Code (generated file: src/stores/useSocialStore.ts)
```ts
import create from 'zustand'
import { persist } from 'zustand/middleware'
type Endorsement = {
id: string
paperId: string
userId: string
message?: string
createdAt: string
}
type SocialState = {
endorsements: Record<string, Endorsement[]>
likes: Record<string, string[]>
addEndorsement: (paperId: string, endorser: Omit<Endorsement,'id'|'createdAt'>) => void
toggleLike: (paperId: string, userId: string) => void
reset: () => void
}
export const useSocialStore = create<SocialState>(persist(
(set) => ({
endorsements: {},
likes: {},
addEndorsement: (paperId, endorser) => set((state) => {
const list = state.endorsements[paperId] ?? []
const newItem = {
id: (typeof crypto !== 'undefined' && (crypto as any).randomUUID) ? (crypto as any).randomUUID() : Date.now().toString(),
...endorser,
createdAt: new Date().toISOString()
}
return { endorsements: { ...state.endorsements, [paperId]: [...list, newItem] } }
}),
toggleLike: (paperId, userId) => set((state) => {
const users = state.likes[paperId] ?? []
const has = users.includes(userId)
return { likes: { ...state.likes, [paperId]: has ? users.filter(u => u !== userId) : [...users, userId] } }
}),
reset: () => ({ endorsements: {}, likes: {} })
}),
{ name: 'arxiv-social-storage' }
))
export default useSocialStore
```
Notes
- Recommend adding `zustand` and `zustand/middleware` to dependencies and documenting wiring examples in components.

# Copilot Instructions — Researcher Endorsement & Collaboration Platform (Frontend-Only)
Purpose
This file is the authoritative project instruction for the frontend-only Researcher Endorsement & Collaboration Platform. It describes the stack, architecture, data model, Zustand store design, component responsibilities, routing, PDF handling, seeding strategy, dev commands, and React 19 considerations so Copilot agents and contributors can scaffold, modify, test, and demo the app without a backend.
Overview
- Frontend-only React application (React 19) built with Vite and TypeScript (strict mode).
- Global state management with Zustand (persist optional). No Redux. No backend or server-side rendering.
- Mock data loaded at start from `src/mock/seedData.ts` and used by services and the store.
- PDF attachments are stored as in-memory object URLs (URL.createObjectURL) or placeholder URLs in seed data; do not attempt server uploads.
Tech Stack
- React 19 (functional components only)
- Vite (latest)
- TypeScript (strict)
- Zustand (+ optional middleware: persist, devtools)
- React Router v6+
- Tailwind CSS (preferred) or lightweight CSS modules
- uuid or crypto.randomUUID for IDs (fallback to Date.now())
Project goals
- Let researchers create profiles (specialties) and post updates including attached PDFs.
- Allow endorsing users (per-specialty) and endorsing posts.
- Entire app runs client-side with realistic mock data, enabling demos and CLI-driven scaffolding.
Folder structure (recommended)
src/
main.tsx
App.tsx
routes/
Home.tsx
Profile.tsx
CreateUser.tsx
PostDetail.tsx
components/
Navbar.tsx
Feed.tsx
PostCard.tsx
UserCard.tsx
EndorseButton.tsx
PDFPreview.tsx
CreatePostModal.tsx
store/
useAppStore.ts
types/
User.ts
Post.ts
mock/
seedData.ts
hooks/
useCurrentUser.ts
services/
mockApi.ts
utils/
fileHelpers.ts
Type definitions (examples)
// src/types/User.ts
export interface User {
id: string
name: string
email: string
bio: string
specialties: string[]
endorsements: Record<string, number>
createdAt: number // Date.now()
}
// src/types/Post.ts
export interface Post {
id: string
authorId: string
content: string
attachedPDF?: {
name: string
url: string
}
endorsements: number
createdAt: number // Date.now()
}
Zustand store design (src/store/useAppStore.ts)
- Use TypeScript generics for the store interface and actions.
- State shape:
- users: User[]
- posts: Post[]
- currentUserId: string | null
- selectedPostId: string | null
- ui: { isCreatePostOpen: boolean }
- Actions (signatures):
- seedData(): void
- createUser(data: Omit<User, 'id' | 'createdAt' | 'endorsements'>): string
- setCurrentUser(id: string | null): void
- createPost(data: { authorId: string; content: string; file?: File | null }): string
- endorseUser(userId: string, specialty: string): void
- endorsePost(postId: string): void
- attachPDFToPost(postId: string, file: File): void
- toggleCreatePost(): void
- reset(): void
Implementation notes
- Always use functional updates to maintain immutability:
set((state) => ({ posts: [newPost, ...state.posts] }))
- For IDs: use `crypto.randomUUID()` when available, else fallback to `String(Date.now())`.
- Use timestamps (numbers) for createdAt to simplify serialization: `Date.now()`.
- If using `persist`, be aware object URLs cannot be serialized; persist only primitive fields or placeholder URLs and avoid persisting File or object URL references.
PDF handling
- When a user attaches a PDF in the CreatePostModal:
1. Validate file type is `application/pdf`; reject others.
2. Create an object URL: `const url = URL.createObjectURL(file)`.
3. Store `{ name: file.name, url }` on the post object in the store.
4. In PDFPreview component, render `<iframe src={url} />` or an `<embed>`.
5. Revoke object URL on component unmount with `URL.revokeObjectURL(url)`; avoid revoking while still referenced by the store/view.
- If implementing persistence: instead store a placeholder downloadable URL in `seedData` and do not persist object URLs.
Seeding (src/mock/seedData.ts)
- Create at least 5 users with distinct specialties, e.g.:
- AI (cs.AI)
- Neuroscience
- Climate Science
- Quantum Physics
- Economics
- Create 10 posts distributed across those authors; include 2–3 posts with `attachedPDF` as placeholder URLs.
- Add some pre-existing endorsement counts per user specialty.
- Provide `seedData()` helper that `useAppStore` calls at app init if state is empty.
Routing (React Router v6+)
- Routes to implement:
- `/` → Home (Feed view)
- `/profile/:id` → Profile page
- `/create-user` → CreateUser page
- `/post/:id` → PostDetail page
- Use `<BrowserRouter>` in main.tsx.
Home page layout
- Centered feed with max-width ~900px.
- Two-column desktop layout (feed + sidebar). Sidebar hidden on small screens.
- Floating Create Post button (controlled by `ui.isCreatePostOpen`).
- Sidebar shows suggested users (3 random users excluding current user).
PostCard responsibilities
- Show author name (link to /profile/:id), specialties as tags, content, attached PDF preview, endorse button, and timestamp.
- Use `React.memo` to avoid re-renders when unrelated state changes.
- Only select the slice of store state needed: e.g., `useAppStore((s) => ({ post: s.posts.find(p => p.id===id), endorsePost: s.endorsePost }), shallow)`.
Endorsement logic
- Endorse a user's specialty from their profile: increments `user.endorsements[specialty]`.
- Endorse a post: increments `post.endorsements`.
- Prevent self-endorsement: if `currentUserId === targetUserId`, disable the endorsement action.
- Provide optimistic UI updates: update the store synchronously; rollback only on detected invariant violations (rare since no server).
- Optional: Prevent duplicate endorsements from the same session by tracking `sessionEndorsements: Record<string, Set<string>>` in memory (not persisted) if desired.
Create User flow
- Form fields: name, email, bio, specialties (comma-separated).
- On submit: validate fields, parse specialties to array, generate id (uuid), createdAt = Date.now(), endorsements = {} (zeroed specialties), add to store, set as current user, navigate to profile.
Create Post Modal
- Controlled by `ui.isCreatePostOpen` in store.
- Fields: textarea (required), file input (accept PDF).
- On submit:
- Validate currentUser exists else disable submit.
- If file, create object URL and attach.
- Use `startTransition(() => createPost(...))` to avoid blocking UI.
- Close modal after optimistic update.
Performance recommendations
- Use selective selectors: read minimal data slices from Zustand to reduce re-renders.
- Use `React.memo` and `useCallback` where appropriate.
- Format long lists with virtualization only if needed (not required for 10s-100s items in demo).
Accessibility
- Use semantic HTML and label inputs.
- Ensure keyboard access to modal and focus trap.
- Buttons should have accessible names (aria-label when icon-only).
- PDF iframe should have title attribute for screen readers.
Testing (optional but recommended)
- Use Vitest + @testing-library/react.
- Test PostCard rendering, endorse button behavior (calls `endorsePost`), and CreateUser flow.
Dev commands
- Install: `npm install`
- Dev: `npm run dev`
- Build: `npm run build`
- Preview: `npm run preview`
- Test: `npm run test`
- Lint/format: `npm run lint` / `npm run format`
React 19-specific guidance
- Use `startTransition` for heavy UI updates (e.g., creating a new post and rerendering many components).
- Prefer modern hooks patterns and avoid legacy lifecycle logic.
Persistence notes (optional enhancement)
- If enabling `persist` middleware on Zustand, exclude or adapt `attachedPDF.url` handling since object URLs are not serializable.
- Best pattern: persist posts and users (primitive fields) and persist `attachedPDF` only if it is a stable URL (seeded placeholder), not object URLs created from local Files.
Edge cases & Validation
- No current user → disable post creation and show CTA to create/select a user.
- Invalid PDF type → show validation error and reject the file.
- Empty feed → display an empty state and suggested actions.
How agents should use this file
- Use this instruction to scaffold files, create stores, seed data, and generate components that conform to the types and store signatures above.
- Agents that generate files should place them under the `src/` paths listed here and reference the types in `src/types`.
- When generating tests or docs, reference the sample data and the `seedData.ts` location.

# Power Apps Code Apps Development Instructions
Instructions for generating high-quality Power Apps Code Apps using TypeScript, React, and Power Platform SDK, following Microsoft's official best practices and preview capabilities.
## Project Context
- **Power Apps Code Apps**: Code-first web app development with Power Platform integration
- **TypeScript + React**: Recommended frontend stack with Vite bundler
- **Power Platform SDK**: @microsoft/power-apps (current version ^1.0.3) for connector integration
- **PAC CLI**: Power Platform CLI for project management and deployment
- **Port 3000**: Required for local development with Power Platform SDK
- **Power Apps Premium**: End-user licensing requirement for production use
## Development Standards
### Project Structure
- Use well-organized folder structure with clear separation of concerns:
```
src/
├── components/ # Reusable UI components
├── hooks/ # Custom React hooks for Power Platform
├── generated/
│ ├── services/ # Generated connector services (PAC CLI)
│ └── models/ # Generated TypeScript models (PAC CLI)
├── utils/ # Utility functions and helpers
├── types/ # TypeScript type definitions
├── PowerProvider.tsx # Power Platform context wrapper
└── main.tsx # Application entry point
```
- Keep generated files (`generated/services/`, `generated/models/`) separate from custom code
- Use consistent naming conventions (kebab-case for files, PascalCase for components)
### TypeScript Configuration
- Set `verbatimModuleSyntax: false` in tsconfig.json for Power Apps SDK compatibility
- Enable strict mode for type safety with recommended tsconfig.json:
```json
{
"compilerOptions": {
"target": "ES2020",
"useDefineForClassFields": true,
"lib": ["ES2020", "DOM", "DOM.Iterable"],
"module": "ESNext",
"skipLibCheck": true,
"verbatimModuleSyntax": false,
"moduleResolution": "bundler",
"allowImportingTsExtensions": true,
"resolveJsonModule": true,
"isolatedModules": true,
"noEmit": true,
"jsx": "react-jsx",
"strict": true,
"noUnusedLocals": true,
"noUnusedParameters": true,
"noFallthroughCasesInSwitch": true,
"baseUrl": ".",
"paths": {
"@/*": ["./src/*"]
}
}
}
```
- Use proper typing for Power Platform connector responses
- Configure path alias with `"@": path.resolve(__dirname, "./src")` for cleaner imports
- Define interfaces for app-specific data structures
- Implement error boundaries and proper error handling types
### Advanced Power Platform Integration
#### Custom Control Frameworks (PCF Controls)
- **Integrate PCF controls**: Embed Power Apps Component Framework controls in Code Apps
```typescript
// Example: Using custom PCF control for data visualization
import { PCFControlWrapper } from './components/PCFControlWrapper';
const MyComponent = () => {
return (
<PCFControlWrapper
controlName="CustomChartControl"
dataset={chartData}
configuration={chartConfig}
/>
);
};
```
- **PCF control communication**: Handle events and data binding between PCF and React
- **Custom control deployment**: Package and deploy PCF controls with Code Apps
#### Power BI Embedded Analytics
- **Embed Power BI reports**: Integrate interactive dashboards and reports
```typescript
import { PowerBIEmbed } from 'powerbi-client-react';
const DashboardComponent = () => {
return (
<PowerBIEmbed
embedConfig={{
type: 'report',
id: reportId,
embedUrl: embedUrl,
accessToken: accessToken,
tokenType: models.TokenType.Aad,
settings: {
panes: { filters: { expanded: false, visible: false } }
}
}}
/>
);
};
```
- **Dynamic report filtering**: Filter Power BI reports based on Code App context
- **Report export functionality**: Enable PDF, Excel, and image exports
#### AI Builder Integration
- **Cognitive services integration**: Use AI Builder models for form processing, object detection
```typescript
// Example: Document processing with AI Builder
const processDocument = async (file: File) => {
const formData = new FormData();
formData.append('file', file);
const result = await AIBuilderService.ProcessDocument({
modelId: 'document-processing-model-id',
document: formData
});
return result.extractedFields;
};
```
- **Prediction models**: Integrate custom AI models for business predictions
- **Sentiment analysis**: Analyze text sentiment using AI Builder
- **Object detection**: Implement image analysis and object recognition
#### Power Virtual Agents Integration
- **Chatbot embedding**: Integrate Power Virtual Agents bots within Code Apps
```typescript
import { DirectLine } from 'botframework-directlinejs';
import { WebChat } from 'botframework-webchat';
const ChatbotComponent = () => {
const directLine = new DirectLine({
token: chatbotToken
});
return (
<div style={{ height: '400px', width: '100%' }}>
<WebChat directLine={directLine} />
</div>
);
};
```
- **Context passing**: Share Code App context with chatbot conversations
- **Custom bot actions**: Trigger Code App functions from bot interactions
- Use generated TypeScript services from PAC CLI for connector operations
- Implement proper authentication flows with Microsoft Entra ID
- Handle connector consent dialogs and permission management
- PowerProvider implementation pattern (no SDK initialization required in v1.0):
```typescript
import type { ReactNode } from "react";
export default function PowerProvider({ children }: { children: ReactNode }) {
return <>{children}</>;
}
```
- Follow officially supported connector patterns:
- SQL Server (including Azure SQL)
- SharePoint
- Office 365 Users/Groups
- Azure Data Explorer
- OneDrive for Business
- Microsoft Teams
- Dataverse (CRUD operations)
### React Patterns
- Use functional components with hooks for all new development
- Implement proper loading and error states for connector operations
- Consider Fluent UI React components (as used in official samples)
- Use React Query or SWR for data fetching and caching when appropriate
- Follow React best practices for component composition
- Implement responsive design with mobile-first approach
- Install key dependencies following official samples:
- `@microsoft/power-apps` for Power Platform SDK
- `@fluentui/react-components` for UI components
- `concurrently` for parallel script execution (dev dependency)
### Data Management
- Store sensitive data in data sources, never in application code
- Use generated models for type-safe connector operations
- Implement proper data validation and sanitization
- Handle offline scenarios gracefully where possible
- Cache frequently accessed data appropriately
#### Advanced Dataverse Relationships
- **Many-to-many relationships**: Implement junction tables and relationship services
```typescript
// Example: User-to-Role many-to-many relationship
const userRoles = await UserRoleService.getall();
const filteredRoles = userRoles.filter(ur => ur.userId === currentUser.id);
```
- **Polymorphic lookups**: Handle customer fields that can reference multiple entity types
```typescript
// Handle polymorphic customer lookup (Account or Contact)
const customerType = record.customerType; // 'account' or 'contact'
const customerId = record.customerId;
const customer = customerType === 'account'
? await AccountService.get(customerId)
: await ContactService.get(customerId);
```
- **Complex relationship queries**: Use $expand and $filter for efficient data retrieval
- **Relationship validation**: Implement business rules for relationship constraints
### Performance Optimization
- Use React.memo and useMemo for expensive computations
- Implement code splitting and lazy loading for large applications
- Optimize bundle size with tree shaking
- Use efficient connector query patterns to minimize API calls
- Implement proper pagination for large data sets
#### Offline-First Architecture with Sync Patterns
- **Service Worker implementation**: Enable offline functionality
```typescript
// Example: Service worker registration
if ('serviceWorker' in navigator) {
window.addEventListener('load', () => {
navigator.serviceWorker.register('/sw.js')
.then(registration => console.log('SW registered:', registration))
.catch(error => console.log('SW registration failed:', error));
});
}
```
- **Local data storage**: Use IndexedDB for offline data persistence
```typescript
// Example: IndexedDB wrapper for offline storage
class OfflineDataStore {
async saveData(key: string, data: any) {
const db = await this.openDB();
const transaction = db.transaction(['data'], 'readwrite');
transaction.objectStore('data').put({ id: key, data, timestamp: Date.now() });
}
async loadData(key: string) {
const db = await this.openDB();
const transaction = db.transaction(['data'], 'readonly');
return transaction.objectStore('data').get(key);
}
}
```
- **Sync conflict resolution**: Handle data conflicts when coming back online
- **Background sync**: Implement periodic data synchronization
- **Progressive Web App (PWA)**: Enable app installation and offline capabilities
### Security Best Practices
- Never store secrets or sensitive configuration in code
- Use Power Platform's built-in authentication and authorization
- Implement proper input validation and sanitization
- Follow OWASP security guidelines for web applications
- Respect Power Platform data loss prevention policies
- Implement HTTPS-only communication
### Error Handling
- Implement comprehensive error boundaries in React
- Handle connector-specific errors gracefully
- Provide meaningful error messages to users
- Log errors appropriately without exposing sensitive information
- Implement retry logic for transient failures
- Handle network connectivity issues
### Testing Strategies
- Write unit tests for business logic and utilities
- Test React components with React Testing Library
- Mock Power Platform connectors in tests
- Implement integration tests for critical user flows
- Use TypeScript for better test safety
- Test error scenarios and edge cases
### Development Workflow
- Use PAC CLI for project initialization and connector management
- Follow git branching strategies appropriate for team size
- Implement proper code review processes
- Use linting and formatting tools (ESLint, Prettier)
- Configure development scripts using concurrently:
- `"dev": "concurrently \"vite\" \"pac code run\""`
- `"build": "tsc -b && vite build"`
- Implement automated testing in CI/CD pipelines
- Follow semantic versioning for releases
### Deployment and DevOps
- Use `npm run build` followed by `pac code push` for deployment
- Implement proper environment management (dev, test, prod)
- Use environment-specific configuration files
- Implement blue-green or canary deployment strategies when possible
- Monitor application performance and errors in production
- Implement proper backup and disaster recovery procedures
#### Multi-Environment Deployment Pipelines
- **Environment-specific configurations**: Manage dev/test/staging/prod environments
```json
// Example: environment-specific config files
// config/development.json
{
"powerPlatform": {
"environmentUrl": "https://dev-env.crm.dynamics.com",
"apiVersion": "9.2"
},
"features": {
"enableDebugMode": true,
"enableAnalytics": false
}
}
```
- **Automated deployment pipelines**: Use Azure DevOps or GitHub Actions
```yaml
# Example Azure DevOps pipeline step
- task: PowerPlatformToolInstaller@2
- task: PowerPlatformSetConnectionVariables@2
inputs:
authenticationType: 'PowerPlatformSPN'
applicationId: '$(AppId)'
clientSecret: '$(ClientSecret)'
tenantId: '$(TenantId)'
- task: PowerPlatformPublishCustomizations@2
```
- **Environment promotion**: Automated promotion from dev → test → staging → prod
- **Rollback strategies**: Implement automated rollback on deployment failures
- **Configuration management**: Use Azure Key Vault for environment-specific secrets
## Code Quality Guidelines
### Component Development
- Create reusable components with clear props interfaces
- Use composition over inheritance
- Implement proper prop validation with TypeScript
- Follow single responsibility principle
- Write self-documenting code with clear naming
### State Management
- Use React's built-in state management for simple scenarios
- Consider Redux Toolkit for complex state management
- Implement proper state normalization
- Avoid prop drilling with context or state management libraries
- Use derived state and computed values efficiently
### API Integration
- Use generated services from PAC CLI for consistency
- Implement proper request/response interceptors
- Handle authentication token management
- Implement request deduplication and caching
- Use proper HTTP status code handling
### Styling and UI
- Use consistent design system or component library
- Implement responsive design with CSS Grid/Flexbox
- Follow accessibility guidelines (WCAG 2.1)
- Use CSS-in-JS or CSS modules for component styling
- Implement dark mode support when appropriate
- Ensure mobile-friendly user interfaces
#### Advanced UI/UX Patterns
##### Design System Implementation with Component Libraries
- **Component library structure**: Build reusable component system
```typescript
// Example: Design system button component
interface ButtonProps {
variant: 'primary' | 'secondary' | 'danger';
size: 'small' | 'medium' | 'large';
disabled?: boolean;
onClick: () => void;
children: React.ReactNode;
}
export const Button: React.FC<ButtonProps> = ({
variant, size, disabled, onClick, children
}) => {
const classes = `btn btn-${variant} btn-${size} ${disabled ? 'btn-disabled' : ''}`;
return <button className={classes} onClick={onClick} disabled={disabled}>{children}</button>;
};
```
- **Design tokens**: Implement consistent spacing, colors, typography
- **Component documentation**: Use Storybook for component documentation
##### Dark Mode and Theming Systems
- **Theme provider implementation**: Support multiple themes
```typescript
// Example: Theme context and provider
const ThemeContext = createContext({
theme: 'light',
toggleTheme: () => {}
});
export const ThemeProvider: React.FC<{children: ReactNode}> = ({ children }) => {
const [theme, setTheme] = useState<'light' | 'dark'>('light');
const toggleTheme = () => {
setTheme(prev => prev === 'light' ? 'dark' : 'light');
};
return (
<ThemeContext.Provider value={{ theme, toggleTheme }}>
<div className={`theme-${theme}`}>{children}</div>
</ThemeContext.Provider>
);
};
```
- **CSS custom properties**: Use CSS variables for dynamic theming
- **System preference detection**: Respect user's OS theme preference
##### Responsive Design Advanced Patterns
- **Container queries**: Use container-based responsive design
```css
/* Example: Container query for responsive components */
.card-container {
container-type: inline-size;
}
@container (min-width: 400px) {
.card {
display: grid;
grid-template-columns: 1fr 1fr;
}
}
```
- **Fluid typography**: Implement responsive font scaling
- **Adaptive layouts**: Change layout patterns based on screen size and context
##### Animation and Micro-interactions
- **Framer Motion integration**: Smooth animations and transitions
```typescript
import { motion, AnimatePresence } from 'framer-motion';
const AnimatedCard = () => {
return (
<motion.div
initial={{ opacity: 0, y: 20 }}
animate={{ opacity: 1, y: 0 }}
exit={{ opacity: 0, y: -20 }}
transition={{ duration: 0.3 }}
whileHover={{ scale: 1.02 }}
className="card"
>
Card content
</motion.div>
);
};
```
- **Loading states**: Animated skeletons and progress indicators
- **Gesture recognition**: Swipe, pinch, and touch interactions
- **Performance optimization**: Use CSS transforms and will-change property
##### Accessibility Automation and Testing
- **ARIA implementation**: Proper semantic markup and ARIA attributes
```typescript
// Example: Accessible modal component
const Modal: React.FC<{isOpen: boolean, onClose: () => void, children: ReactNode}> = ({
isOpen, onClose, children
}) => {
useEffect(() => {
if (isOpen) {
document.body.style.overflow = 'hidden';
const focusableElement = document.querySelector('[data-autofocus]') as HTMLElement;
focusableElement?.focus();
}
return () => { document.body.style.overflow = 'unset'; };
}, [isOpen]);
return (
<div
role="dialog"
aria-modal="true"
aria-labelledby="modal-title"
className={isOpen ? 'modal-open' : 'modal-hidden'}
>
{children}
</div>
);
};
```
- **Automated accessibility testing**: Integrate axe-core for accessibility testing
- **Keyboard navigation**: Implement full keyboard accessibility
- **Screen reader optimization**: Test with NVDA, JAWS, and VoiceOver
##### Internationalization (i18n) and Localization
- **React-intl integration**: Multi-language support
```typescript
import { FormattedMessage, useIntl } from 'react-intl';
const WelcomeMessage = ({ userName }: { userName: string }) => {
const intl = useIntl();
return (
<h1>
<FormattedMessage
id="welcome.title"
defaultMessage="Welcome, {userName}!"
values={{ userName }}
/>
</h1>
);
};
```
- **Language detection**: Automatic language detection and switching
- **RTL support**: Right-to-left language support for Arabic, Hebrew
- **Date and number formatting**: Locale-specific formatting
- **Translation management**: Integration with translation services
## Current Limitations and Workarounds
### Known Limitations
- Content Security Policy (CSP) not yet supported
- Storage SAS IP restrictions not supported
- No Power Platform Git integration
- Dataverse solutions supported, but solution packager and source code integration are limited
- Application Insights supported through SDK logger configuration (no built-in native integration)
### Workarounds
- Use alternative error tracking solutions if needed
- Implement manual deployment workflows
- Use external tools for advanced analytics
- Plan for future migration to supported features
## Documentation Standards
- Maintain comprehensive README.md with setup instructions
- Document all custom components and hooks
- Include troubleshooting guides for common issues
- Document deployment procedures and requirements
- Maintain changelog for version updates
- Include architectural decision records for major choices
## Troubleshooting Common Issues
### Development Issues
- **Port 3000 conflicts**: Kill existing processes with `netstat -ano | findstr :3000` then `taskkill /PID {PID} /F`
- **Authentication failures**: Verify environment setup and user permissions with `pac auth list`
- **Package installation failures**: Clear npm cache with `npm cache clean --force` and reinstall
- **TypeScript compilation errors**: Check verbatimModuleSyntax setting and SDK compatibility
- **Connector permission errors**: Ensure proper consent flow and admin permissions
- **PowerProvider issues**: Ensure v1.0 apps do not wait on SDK initialization
- **Vite dev server issues**: Ensure host and port configuration match requirements
### Deployment Issues
- **Build failures**: Verify all dependencies with `npm audit` and check build configuration
- **Authentication errors**: Re-authenticate PAC CLI with `pac auth clear` then `pac auth create`
- **Connector unavailable**: Verify connector setup in Power Platform and connection status
- **Performance issues**: Optimize bundle size with `npm run build --report` and implement caching
- **Environment mismatch**: Confirm correct environment selection with `pac env list`

# GitHub Copilot Agent Skills
This directory contains project-specific skills for GitHub Copilot agents. Skills help Copilot perform specialized tasks in a consistent, repeatable way.
## About Agent Skills
Agent Skills are folders containing instructions, scripts, and resources that Copilot can load when relevant to improve its performance. They work with:
- Copilot coding agent
- GitHub Copilot CLI
- Visual Studio Code agent mode
## Directory Structure
Each skill should be in its own subdirectory with the following structure:
```
.github/skills/
├── skill-name/
│ ├── SKILL.md # Required: Skill instructions with YAML frontmatter
│ ├── scripts/ # Optional: Helper scripts
│ └── examples/ # Optional: Example files or templates
└── another-skill/
└── SKILL.md
```
## Creating a New Skill
1. **Create a directory** for your skill with a lowercase, hyphenated name:
```
.github/skills/your-skill-name/
```
2. **Create a `SKILL.md` file** with:
- **YAML frontmatter** containing:
- `name` (required): Unique identifier (lowercase, hyphenated)

# Action Dispatcher
When to use this skill
- Use when adding or changing business logic inside Zustand stores or when moving UI logic into testable actions.
- Triggered by prompts about endorsement toggles, likes, and user profile updates.
Instructions
1. First Step: Implement pure functions for actions where possible (e.g., `addEndorsement(state, payload) => newState`).
2. Second Step: Hook these functions into the store actions so they can be unit-tested separately from UI.
3. Third Step: Add unit tests for each action and ensure edge cases (duplicate endorsements, idempotency) are handled.
Examples
- `toggleLike(paperId, userId)` checks current likes and adds/removes the user id.
Notes
- Keep action functions deterministic and avoid direct DOM or side-effect operations inside them; delegate I/O to services.

# Alias Guardian
When to use this skill
- Run after adding `tsconfig` path aliases or when many long relative imports exist.
- Triggered by prompts to convert `../../..` style imports to `@/` aliases.
Instructions
1. First Step: Ensure `tsconfig.json` has `paths` configured (`"@/*": ["src/*"]`) and `vite.config.ts` supports the aliases (via `vite-tsconfig-paths` or manual `resolve.alias`).
2. Second Step: Use an AST-based tool (e.g., `jscodeshift`, `ts-morph`) or a controlled regex to find and replace relative import paths. Prefer AST to avoid accidental matches.
3. Third Step: Update affected files' imports to the alias form and run TypeScript to verify no resolution errors.
Examples
- Before: `import PaperCard from '../../components/molecules/PaperCard'`
- After: `import PaperCard from '@/components/molecules/PaperCard'`
Additional Resources
- ts-morph: https://github.com/dsherret/ts-morph
- jscodeshift: https://github.com/facebook/jscodeshift
Notes
- Always run tests and TypeScript type-check after mass refactors; commit in a dedicated branch and use Git to move files safely.

---
# Atom Smith
When to use this skill
- When adding or standardizing small UI building blocks used across the app.
- Triggered by requests to scaffold typed atoms with accessible defaults.
Instructions
1. First Step: Create `src/components/atoms/<AtomName>.tsx` with a minimal, accessible markup and a typed props interface.
2. Second Step: Add `index.ts` to the atoms folder to export the atom and document common props in JSDoc or comments.
3. Third Step: Provide example stories (if Storybook exists) or a test that confirms basic render and accessibility attributes.
Examples
- Button atom snippet:
```tsx
export type ButtonProps = React.ButtonHTMLAttributes<HTMLButtonElement> & { variant?: 'primary' | 'ghost' }
export const Button: React.FC<ButtonProps> = ({ children, className, variant = 'primary', ...rest }) => (
<button className={`px-3 py-1 rounded ${variant === 'primary' ? 'bg-blue-600 text-white' : 'bg-transparent' } ${className ?? ''}`} {...rest}>{children}</button>
)
```
Notes
- Ensure atoms are accessible by default (proper role, aria-labels when appropriate, keyboard focus).
- Keep atoms small; styling via Tailwind utility classes is recommended for consistency.

# Atomic Scaffolder
When to use this skill
- Use when starting the UI layer or when reorganizing components into Atomic Design.
- Triggered by prompts that request a structured components tree or sample atoms/molecules.
Instructions
1. First Step: Create `src/components/{atoms,molecules,organisms,templates,pages}` directories and ensure `src/components/index.ts` exists as a barrel.
2. Second Step: Add `index.ts` in each folder that re-exports components to simplify imports (e.g., `export * from './atoms/Button'`).
3. Third Step: Optionally scaffold a small set of example atoms (Button, Input, Badge) and a molecule (PaperCard) to demonstrate wiring and naming conventions.
Examples
- Generated tree:
src/components/
atoms/
Button.tsx
index.ts
molecules/
PaperCard.tsx
index.ts
Additional Resources
- Atomic Design: https://bradfrost.com/blog/post/atomic-web-design/

# Custom Hook Crafter
When to use this skill
- Use when component logic involves side effects or needs to be shared across components.
- Triggered by requests to move data fetching, pagination, caching, or subscriptions into hooks.
Instructions
1. First Step: Identify repeated data-fetching or local-state patterns and define hook API (inputs, outputs, error handling).
2. Second Step: Implement the hook under `src/hooks/` using `useEffect`, `useRef` for abort controllers, and caching strategies as needed.
3. Third Step: Add unit tests and examples showing usage in components; document returned values and loading/error semantics.
Examples
- `useArXivFetch(query, options)` returns `{ data, loading, error, refetch }` and uses an internal cache keyed by query.

# Mock Data Generator
When to use this skill
- Use early in development to simulate arXiv papers, users, and endorsement relations for UI and store integration.
- Triggered by requests to create JSON or TypeScript fixtures under `src/data/mockData.ts`.
Instructions
1. First Step: Produce realistic paper fixtures (title, authors, categories, abstract, submittedAt) and user fixtures (id, name, affiliation, expertiseAreas).
2. Second Step: Optionally seed persisted store on first load if no data exists, using the mock dataset to populate `usePaperStore` or similar.
3. Third Step: Provide utility functions to filter and paginate mock data to emulate real API behavior.
Examples
- `src/data/mockData.ts` exports `{ papers, users, endorsements }` and helper `seedMockData()`.
Notes
- Keep the dataset representative (vary categories, dates) so components (sorting, filtering) can be tested effectively.

# Module Encapsulator
When to use this skill
- Use when several components, hooks, and types belong to a single feature and should be colocated.
- Triggered by requests to organize code by feature boundary rather than only by technical layer.
Instructions
1. First Step: Propose a module layout (e.g., `src/modules/endorsements/{components,hooks,types,services}`) and create an `index.ts` to re-export public APIs.
2. Second Step: Move or copy existing files into the module, update imports to use the module boundary (e.g., `@/modules/endorsements`).

# Organism Architect
When to use this skill
- Use when creating page sections that aggregate molecules and small stateful interactions.

Instructions
1. First Step: Design the organism's responsibilities (data fetching vs. purely presentational) and choose which molecules it composes.
2. Second Step: Implement the organism under `src/components/organisms/`, use hooks for data and local UI state, and expose minimal props for customization.
3. Third Step: Add skeletons or loading states (spinners/skeleton cards) and tests verifying interactions and accessibility.
Examples
- PaperFeed: fetches a list of papers via `useArXivFetch`, renders `PaperCard` molecules, supports infinite scroll or pagination.
Notes
- Keep organisms at the page level; avoid adding global app logic here—use stores or modules for cross-cutting concerns.

When to use this skill
- Use when multiple organisms contain the same rendering logic or state transformation.
- Triggered by requests to reduce duplication and improve maintainability.
Instructions
1. First Step: Scan the codebase for duplicated JSX blocks or near-identical functions using `grep`, `ripgrep`, or AST comparison.
2. Second Step: Propose a refactor plan: extract a Molecule, a utility function in `src/utils`, or move a hook into `src/hooks`.
3. Third Step: Provide a code diff or patch demonstrating the extraction and update imports across affected files.

When to use this skill
- Use when you need consistent page scaffolding (headers, sidebars, footers) across pages.
- Triggered by requests to standardize page layouts or to create reusable layout wrappers.
Instructions
1. First Step: Define required regions (header, nav, main, aside, footer) and how children will be injected (React `children` or named slots via props).
2. Second Step: Implement layouts in `src/components/templates/` and ensure they accept a `children` prop and optional slot props (e.g., `sidebar`).
3. Third Step: Use templates in pages under `src/pages/` and provide examples of composition.
Examples
- DashboardLayout:
`<DashboardLayout sidebar={<ProfileCard/>}><PaperFeed/></DashboardLayout>`
Notes

- Recommend using `vite-tsconfig-paths` to avoid duplicating aliases in Vite config.
- If running in CI, show how to set `VITE_` env vars during build.

name: zustand-store-manager
description: "Generates typed Zustand stores (usePaperStore, useAuthStore) with devtools and persist middleware for localStorage."
license: MIT
triggers:
- "create zustand store"
- "generate usePaperStore"
- "persist zustand"
---
# Zustand Store Manager
When to use this skill
- Use when centralizing client state (papers, endorsements, likes, user profile) without a backend.
- Triggered by requests to scaffold or update stores, add persistence, or wire devtools.
Instructions
1. First Step: Create typed store files under `src/stores/` (e.g., `usePaperStore.ts`) using `create` from `zustand` and `persist`/`devtools` middleware.
2. Second Step: Expose actions and selectors that the UI will consume (`addEndorsement`, `toggleLike`, `fetchPapers` placeholder).
3. Third Step: Document how to access state in components and how to reset/seed state for tests.
Examples
- `usePaperStore` exposes `papers`, `loading`, `addEndorsement(paperId, endorser)` and `reset()`.
Notes
- Include clear type definitions for the store payloads to keep UI and store in sync.
- Recommend `zustand/middleware` persist name (`arxiv-social-storage`) and a migration strategy when types change.
