+# Code Style and Conventions
+
+## General
+- **Language**: PHP (PrestaShop conventions)
+- **Comments/Notes**: Often in Polish (this is a Polish project)
+- **No strict linting** - no PHPStan/Psalm/PHP-CS-Fixer configured for the project
+
+## PrestaShop Module Conventions
+- Module class extends `Module`
+- Module file named same as module folder (e.g., `customfeaturetab/customfeaturetab.php`)
+- Hooks: `hookDisplay*`, `hookAction*` methods
+- Templates: Smarty `.tpl` files in `views/templates/`
+- Admin controllers in `controllers/admin/`
+- Front controllers in `controllers/front/`
+
+## PrestaShop Override Conventions
+- Override classes extend the original class
+- Place in `override/classes/` or `override/controllers/`
+- Must clear cache after adding overrides
+
+## Custom Scripts
+- Root-level PHP scripts include PrestaShop config via:
+  ```php
+  include(dirname(__FILE__).'/config/config.inc.php');
+  include(dirname(__FILE__).'/init.php');
+  ```
+- Use `Tools::getValue()` for GET/POST parameters
+- Use PrestaShop's `Db::getInstance()` for database queries
+
+## Naming
+- Module names: lowercase, no spaces (e.g., `customfeaturetab`)
+- Database tables: `ps_` prefix (PrestaShop convention)
+- Class names: PascalCase
+- Variables/methods: camelCase (PrestaShop convention)
+
+## Theme
+- Active theme: `InterBlue` (customized classic theme)
+- Templates: Smarty `.tpl` files
+- Assets in `themes/InterBlue/assets/`

+# Task Completion Checklist
+
+When a task is completed, follow these steps:
+
+## 1. Code Quality
+- [ ] Code follows PrestaShop conventions (camelCase, Module class structure)
+- [ ] No hardcoded values where configuration should be used
+- [ ] SQL queries use PrestaShop's `Db` class with proper escaping (`pSQL()`, `(int)`)
+- [ ] Comments in Polish or English (match surrounding code)
+
+## 2. Cache
+- [ ] If overrides were added/changed: remind user to clear PrestaShop cache
+- [ ] If Smarty templates changed: cache clear may be needed
+
+## 3. Deployment
+- [ ] Files ready to be synced via FTP (ftp-kr)
+- [ ] No sensitive data (passwords, API keys) committed
+
+## 4. Git
+- [ ] Changes committed with descriptive message
+- [ ] No unnecessary files staged (.vscode cache files excluded)
+
+## 5. Testing
+- [ ] No automated tests in this project - manual testing required
+- [ ] Remind user to test in browser after FTP sync
+
+## Notes
+- Admin panel folder: `admin658c34/` (obfuscated name)
+- empikmarketplace module can override product list view in BO (see NOTATKI.md)
