+## Github Action Rules
+
+- Check if `package.json` exists in project root and summarize key scripts
+- Check if `.nvmrc` exists in project root
+- Check if `.env.example` exists in project root to identify key `env:` variables
+- Always use `git branch -a | cat` to verify whether we use `main` or `master` branch
+- Always use `env:` variables and secrets attached to jobs instead of global workflows
+- Always use `npm ci` for Node-based dependency setup
+- Extract common steps into composite actions in separate files
+- Once you're done, as a final step conduct the following:
+
+1. For each public action always use <tool>"Run Terminal"</tool> to see what is the most up-to-date version (use only major version):
+
+```bash
+curl -s https://api.github.com/repos/{owner}/{repo}/releases/latest | grep '"tag_name":' | sed -E 's/.*"v([0-9]+).*/\1/'
+```
+
+2. (Ask if needed) Use <tool>"Run Terminal"</tool> to fetch README.md and see if we're not using any deprecated actions by mistake:
+
+```bash
+curl -s https://raw.githubusercontent.com/{owner}/{repo}/refs/tags/v{TAG_VERSION}/README.md
+```
+
+3. (Ask if needed) Use <tool>"Run Terminal"</tool> to fetch repo metadata and see if we're not using any deprecated actions by mistake:
+
+```bash
+curl -s https://api.github.com/repos/{owner}/{repo} | grep '"archived":'
+```
+
+4. (Ask if needed) In case of linter issues related to action parameters, try to fetch action description directly from GitHub and use the following command:
+
+```bash
+curl -s https://raw.githubusercontent.com/{owner}/{repo}/refs/heads/{main/master}/action.yml
+```

 ## 🎯 Kluczowe ustawienia
 
 ### `fullyParallel: false`
+
 **Co to robi:** Testy uruchamiają się jeden po drugim
 **Dlaczego:** Łatwiej debugować na początku. Zmień na `true` gdy będziesz mieć dużo stabilnych testów.
 
 ### `workers: 1`
+
 **Co to robi:** Tylko jedna przeglądarka w tym samym czasie
 **Dlaczego:** Stabilniejsze, łatwiej śledzić co się dzieje
 
 ### `trace: "on"`
+
 **Co to robi:** Zapisuje każdy krok testu (kliknięcia, nawigacja, itp.)
 **Jak zobaczyć:** `npx playwright show-trace playwright-report/trace.zip`
 **Kiedy:** Zawsze - zobaczysz dokładnie co poszło nie tak
 
 ### `screenshot: "only-on-failure"`
+
 **Co to robi:** Robi zdjęcie ekranu gdy test failuje
 **Gdzie:** `playwright-report/` folder
 
 ### `video: "off"`
+
 **Co to robi:** Nie nagrywa wideo
 **Dlaczego:** Trace + screenshoty wystarczą, wideo zajmuje dużo miejsca
 **Kiedy włączyć:** Jak będziesz mieć bardzo trudny do zreprodukowania bug
 
 ### `baseURL: "http://localhost:3000"`
+
 **Co to robi:** Możesz pisać `page.goto('/')` zamiast `page.goto('http://localhost:3000/')`
 **Przykład:**
+
 ```typescript
 // Zamiast tego:
-await page.goto('http://localhost:3000/dashboard');
+await page.goto("http://localhost:3000/dashboard");
 
 // Piszesz:
-await page.goto('/dashboard');
+await page.goto("/dashboard");
 ```
 
 ### `webServer`
+
 **Co to robi:** Automatycznie uruchamia `npm run dev` przed testami
 **Bonus:** `reuseExistingServer: true` - jeśli masz już uruchomiony dev server, użyje go (szybciej)

 ## 🎯 Kluczowe ustawienia
 
 ### `environment: "jsdom"`
+
 **Co to robi:** Symuluje środowisko przeglądarki (DOM, window, document)
 **Dlaczego:** Twoje komponenty React potrzebują DOM
 **Alternatywa:** `happy-dom` (szybszy, ale mniej kompatybilny) - zostań przy jsdom
 
 ### `globals: true`
+
 **Co to robi:** Możesz pisać `describe`, `it`, `expect` bez importów
 **Przykład:**
+
 ```typescript
 // Bez globals:
-import { describe, it, expect } from 'vitest';
+import { describe, it, expect } from "vitest";
 
 // Z globals (prostsze!):
-describe('MyComponent', () => {
-  it('should render', () => {
+describe("MyComponent", () => {
+  it("should render", () => {
     expect(true).toBe(true);
   });
 });
 ```
 
 ### `setupFiles: ["./src/test/setup-tests.ts"]`
+
 **Co to robi:** Uruchamia ten plik przed wszystkimi testami
 **Co jest w środku:**
+
 - `@testing-library/jest-dom` (matchery jak `toBeInTheDocument()`)
 - Mocki Next.js (`useRouter`, `usePathname`, itp.)
 - Mocki next-intl, next-themes
 - MSW (Mock Service Worker) setup
 
 ### `css: true`
+
 **Co to robi:** Nie failuje gdy importujesz CSS w komponentach
 **Przykład:**
+
 ```typescript
 // Bez css: true → ERROR
-import './Button.css';
+import "./Button.css";
 
 // Z css: true → OK ✅
-import './Button.css';
+import "./Button.css";
 ```
 
 ## 📊 Coverage (Pokrycie kodu)
 
 ### `reporter: ["text", "html"]`
+
 **Co to robi:**
+
 - `text` - pokazuje wyniki w terminalu
 - `html` - generuje stronę HTML w `coverage/index.html`
 
 **Usunięte:** `json` i `lcov` (niepotrzebne bez CI/CD)
 
 ### `thresholds: 60`
+
 **Co to robi:** Minimalny % pokrycia kodu
 **Zmienione z 70% na 60%** - łatwiej na początek
 
 **4 typy pokrycia:**
+
 - **lines:** % linii kodu które zostały uruchomione
 - **functions:** % funkcji które zostały wywołane
 - **branches:** % ścieżek (if/else) które zostały przetestowane
 - **statements:** % instrukcji które zostały wykonane
 
 **Co się stanie jak spadnie poniżej 60%?**
+
 ```bash
 npm run test:coverage
 # ERROR: Coverage threshold not met!
 ```
 
 ### `exclude` (w coverage)
+
 **Co to robi:** Te pliki nie liczą się do pokrycia
 **Co wykluczamy:**
+
 - `src/test/` - same testy
 - `**/*.config.*` - pliki konfiguracyjne (vitest.config.ts, itp.)
 - `src/db/database.types.ts` - auto-generowane przez Supabase
