# AGENTS.md

## Project Rules
- Use TypeScript strict mode
- All API endpoints must have input validation
- Test coverage no less than 80%
- Run npm run lint before committing

## Code Style
- Use functional components
- Naming: camelCase
- Files: kebab-case

## Prohibited Operations
- Do not modify .env files
- Do not delete test files
- Do not install new dependencies (requires manual confirmation)
