# AGENT CODING STANDARDS
This project is a PHP MVC application using Composer, Twig, and FastRoute, running in an LXC container.
## 🛠️ Development Commands
| Type | Command | Notes |
| :--- | :--- | :--- |
| **Dependencies** | `incus exec www composer install` / `incus exec www composer update` | Run from the host machine. Apache2 with PHP/Composer runs in the INCUS container 'www'. The folder ./ is shared with /var/www/localhost/ in the container, and port 80 is shared with the host. Use `update` after editing `composer.json`. |
| **Linting** | N/A | No dedicated tool. Adhere to PSR-12 standards. |
| **Testing** | `curl localhost` | No testing framework configured. Avoid adding tests until one is introduced. |
## 📐 Code Style & Conventions
1. **Architecture:** Strict MVC pattern. Logic in `src/Controllers`, data access in `src/Models`, views in `templates/`.
2. **Namespacing:** Use `App\` as the base namespace (PSR-4).
3. **Naming:** Classes are `PascalCase`. Functions, methods, and variables are `camelCase`.
4. **Templating:** Use **Twig** (`.twig`). All HTML rendering must be done via Twig.
5. **I18n:** All user-facing strings must use `App\Services\TranslationService` (PHP) or `{{ trans('ID') }}` (Twig).
6. **Error Handling:** Use PHP's native exception handling (`try/catch`). Log critical errors with `error_log()`.
7. **Database:** Access SQLite via `App\Database\Database::getInstance()`. **Do not** use direct `new PDO()`.
8. **Imports:** Use fully qualified class names or `use` statements at the top of the file.
9. **Security:** Never introduce code that exposes or logs secrets and keys. Never commit secrets or keys to the repository.
10. **Types:** Use type hints for function parameters and return types where possible.
11. **Formatting:** Follow PSR-12 standards for code formatting.
12. **Comments:** Do not add comments unless explicitly requested.
13. **Libraries:** Only use libraries already in composer.json. Check composer.json before adding new dependencies.
