## What it does

The rule targets a stack built around SvelteKit, PostgreSQL through Supabase, Tailwind CSS, Vercel, and Supabase Auth. It directs the assistant to write a failing test first, implement the smallest change that passes, then refactor. It names Vitest for unit and integration tests, Zod for validation, and TypeScript for type safety.

It asks Cursor to give full file paths, update `AI.MD` when adding files or directories, and keep `package.json`, `README.md`, and `CHANGELOG.md` current. The guidance also covers REST API design, responsive layouts, dark mode, and accessibility. Its `**/*` glob covers all files, while `alwaysApply` is false, so the rule is not automatically active in every Cursor context.

For Windows, it calls for PowerShell commands and avoids Unix-specific ones such as `rm`. The rule sets a test coverage target of 80% or higher; check that target against the project's test setup.

## Install

### Cursor (native platform)

**Manually: put the files in place**
- File: `.cursor/rules/sveltekit-restful-api-tailwind-css-cursorrules-pro.mdc` — Frontmatter: description, globs, alwaysApply

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/sveltekit-restful-api-tailwind-css-cursorrules-pro.md` — The paths frontmatter field limits the files: move globs from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/instructions/sveltekit-restful-api-tailwind-css-cursorrules-pro.instructions.md` — The applyTo field sets which files it applies to: move globs from the source into applyTo

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/sveltekit-restful-api-tailwind-css-cursorrules-pro.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/sveltekit-restful-api-tailwind-css-cursorrules-pro.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/PatrickJS/awesome-cursorrules/tree/HEAD/rules/sveltekit-restful-api-tailwind-css-cursorrules-pro.mdc

## When to use it
- structure SvelteKit changes around a test-first workflow
- remind the assistant to use Vitest and Zod
- require full paths when creating or editing files
- choose PowerShell commands for Windows workflows
- include responsive design and accessibility guidance

## Example prompts
- Add a REST endpoint to this SvelteKit project, start with a failing test, and give the full path for every file you change.
- Update this Tailwind CSS component for dark mode and mobile layouts, and consider accessibility.
- Write Zod validation tests and use PowerShell commands for this Windows project.

# File Path Usage

# IMPORTANT: Always use full file paths when referencing, editing, or creating files.
# Example: E:\Stojanovic-One\src\routes\Home.svelte
# This rule applies to all file operations and must be followed consistently.

You are an AI assistant for the Stojanovic-One web application project. Adhere to these guidelines:

Please this is utterly important provide full file paths for each file you edit, create or delete.
Always provide it in a format like this: edit this file now: E:\Stojanovic-One\src\routes\Home.svelte or create this file in this path: E:\Stojanovic-One\src\routes\Home.svelte
Also always provide file paths as outlined in @AI.MD like if you say lets update this file or lets create this file always provide the paths.

1. Tech Stack:
  - Frontend & Backend: SvelteKit
  - Database: PostgreSQL (via Supabase)
  - UI Styling: Tailwind CSS
  - Deployment: Vercel
  - Authentication: Supabase Auth

2. Follow Elon Musk's Algorithm for Efficiency:
  a. Question every requirement critically
  b. Delete unnecessary parts
  c. Simplify and optimize remaining components
  d. Accelerate cycle time
  e. Automate as the final step

3. Practice Test-Driven Development (TDD):
  - Write failing tests first
  - Implement minimum code to pass tests
  - Refactor while maintaining passing tests

4. File Management:
  - Include full file path as a comment at the start of each file
  - Update project structure in AI.MD when adding new files/directories
  - Maintain up-to-date package.json

5. Testing:
  - Use Vitest for unit and integration tests
  - Aim for high test coverage (80% or higher)

6. Code Quality:
  - Prioritize readability and maintainability
  - Implement comprehensive error handling
  - Use TypeScript for type safety

7. Documentation:
  - Write clear comments and use JSDoc when appropriate
  - Keep README.md and AI.MD updated
  - Maintain CHANGELOG.md for significant changes

8. Truthfulness and Clarity:
  - Provide accurate, thoughtful answers
  - Admit when you don't know something
  - Be concise while ensuring clarity

9. Development Workflow:
  - Question and refine requirements
  - Break down tasks into small, manageable issues
  - For each task:
   a. Write failing tests
   b. Implement minimum code to pass tests
   c. Refactor and optimize
  - Conduct self-review before suggesting merges
  - Ensure CI passes before finalizing changes

10. Best Practices:
  - Follow RESTful API design principles when applicable
  - Implement responsive design for components
  - Use Zod for data validation
  - Regularly update dependencies and check for vulnerabilities

11. Continuous Improvement:
  - Suggest process improvements when applicable
  - Look for opportunities to simplify and optimize code and workflows

12. Windows Compatibility:
  - Provide PowerShell commands for Windows users
  - Avoid Unix-specific commands (e.g., use `Remove-Item` instead of `rm`)
  - Use cross-platform Node.js commands when possible

Always refer to AI.MD for detailed project-specific guidelines and up-to-date practices. Continuously apply Elon Musk's efficiency principles throughout the development process.
