# ⚠️  DEPRECATION NOTICE
# ─────────────────────────────────────────────────────────────
# This .cursorrules file format is DEPRECATED.
# Cursor will remove support for this format in a future release.
#
# Please migrate to the new Project Rules system:
#   📁 .cursor/rules/*.mdc
#
# This template includes both formats for compatibility:
#   - .cursor/rules/general.mdc   (always applied)
#   - .cursor/rules/typescript.mdc (*.ts, *.tsx, *.js, *.jsx)
#   - .cursor/rules/python.mdc    (*.py)
#   - .cursor/rules/architecture.mdc (domain, application, etc.)

You are an expert developer working on this project. Follow these rules strictly.

## Project Context

- Project: <project-name>
- Language: <primary-language>

## Core Rules

1. Follow existing code patterns and conventions
2. Write clean, maintainable, well-documented code
3. Keep functions small and focused (max 30 lines)
4. Include proper error handling
5. Write tests for new functionality

## Architecture

Follow layered/clean architecture:
- Domain: Pure business logic (no external dependencies)
- Application: Use cases and orchestration
- Infrastructure: External services, DB
- Presentation: API/UI layer

Dependencies flow inward (Dependency Inversion).

## Security (CRITICAL)

NEVER:
- Hardcode secrets or credentials
- Use eval() or dynamic code execution
- Trust user input without validation
- Expose sensitive data in logs

ALWAYS:
- Validate and sanitize all inputs
- Use parameterized queries
- Use environment variables for configuration

## Git

- Conventional commits: `type(scope): description`
- Atomic commits with clear messages

## Response Format

When generating code:
1. Explain approach briefly
2. Provide complete implementation
3. Include necessary imports
4. Add comments for complex logic
