# Playwright Browser Automation

## Overview

This public intake copy packages `plugins/antigravity-awesome-skills-claude/skills/playwright-skill` from `https://github.com/sickn33/antigravity-awesome-skills` into the native Omni Skills editorial shape without hiding its origin.

Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.

This intake keeps the copied upstream files intact and uses the `external_source` block in `metadata.json` plus `ORIGIN.md` as the provenance anchor for review.

IMPORTANT - Path Resolution: This skill can be installed in different locations (plugin system, manual installation, global, or project-specific). Before executing any commands, determine the skill directory based on where you loaded this SKILL.md file, and use that path in all commands below. Replace $SKILLDIR with the actual discovered path. Common installation paths: - Plugin system: <plugin-root>/skills/playwright-skill - Manual global: <agent-home>/skills/playwright-skill - Project-specific: <project>/.agent/skills/playwright-skill # Playwright Browser Automation General-purpose browser automation skill. I'll write custom Playwright code for any automation task you request and execute it via the universal executor. CRITICAL WORKFLOW - Follow these steps in order: 1. Auto-detect dev servers - For localhost testing, ALWAYS run server detection FIRST: ``bash cd $SKILLDIR && node -e "require('./lib/helpers').detectDevServers().then(servers => console.log(JSON.stringify(servers)))" ` - If 1 server found: Use it automatically, inform user - If multiple servers found: Ask user which one to test - If no servers found: Ask for URL or offer to help start dev server 2. Write scripts to /tmp - NEVER write test files to skill directory; always use /tmp/playwright-test-*.js 3. Use visible browser by default - Always use headless: false` unless user specifically requests headless mode 4. Parameterize URLs - Always make URLs configurable via environment variable or constant at top of script

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: How It Works, Execution Pattern, Common Patterns, Inline Execution (Simple Tasks), Available Helpers, Custom HTTP Headers.

## When to Use This Skill

Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.

- This skill is applicable to execute the workflow or actions described in the overview.
- Use when the request clearly matches the imported source intent: IMPORTANT - Path Resolution: This skill can be installed in different locations (plugin system, manual installation, global, or project-specific). Before executing any commands, determine the skill directory based on....
- Use when the operator should preserve upstream workflow detail instead of rewriting the process from scratch.
- Use when provenance needs to stay visible in the answer, PR, or review packet.
- Use when copied upstream references, examples, or scripts materially improve the answer.
- Use when the workflow should remain reviewable in the public intake repo before the private enhancer takes over.

## Operating Table

| Situation | Start here | Why it matters |
| --- | --- | --- |
| First-time use | `metadata.json` | Confirms repository, branch, commit, and imported path through the `external_source` block before touching the copied workflow |
| Provenance review | `ORIGIN.md` | Gives reviewers a plain-language audit trail for the imported source |
| Workflow execution | `API_REFERENCE.md` | Starts with the smallest copied file that materially changes execution |
| Supporting context | `lib/helpers.js` | Adds the next most relevant copied source file without loading the entire package |
| Handoff decision | `## Related Skills` | Helps the operator switch to a stronger native skill when the task drifts |

## Workflow

This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.

1. bash cd $SKILL_DIR npm run setup This installs Playwright and Chromium browser.
2. Confirm the user goal, the scope of the imported workflow, and whether this skill is still the right router for the task.
3. Read the overview and provenance files before loading any copied upstream support files.
4. Load only the references, examples, prompts, or scripts that materially change the outcome for the current request.
5. Execute the upstream workflow while keeping provenance and source boundaries explicit in the working notes.
6. Validate the result against the upstream expectations and the evidence you can point to in the copied files.
7. Escalate or hand off to a related skill when the work moves out of this imported workflow's center of gravity.

### Imported Workflow Notes

#### Imported: Setup (First Time)

```bash
cd $SKILL_DIR
npm run setup
```

This installs Playwright and Chromium browser. Only needed once.

#### Imported: How It Works

1. You describe what you want to test/automate
2. I auto-detect running dev servers (or ask for URL if testing external site)
3. I write custom Playwright code in `/tmp/playwright-test-*.js` (won't clutter your project)
4. I execute it via: `cd $SKILL_DIR && node run.js /tmp/playwright-test-*.js`
5. Results displayed in real-time, browser window visible for debugging
6. Test files auto-cleaned from /tmp by your OS

## Examples

### Example 1: Ask for the upstream workflow directly

```text
Use @playwright-skill-v2 to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.
```

**Explanation:** This is the safest starting point when the operator needs the imported workflow, but not the entire repository.

### Example 2: Ask for a provenance-grounded review

```text
Review @playwright-skill-v2 against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.
```

**Explanation:** Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.

### Example 3: Narrow the copied support files before execution

```text
Use @playwright-skill-v2 for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.
```

**Explanation:** This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.

### Example 4: Build a reviewer packet

```text
Review @playwright-skill-v2 using the copied upstream files plus provenance, then summarize any gaps before merge.
```

**Explanation:** This is useful when the PR is waiting for human review and you want a repeatable audit packet.

#### Imported: Example Usage

```
User: "Test if the marketing page looks good"

Claude: I'll test the marketing page across multiple viewports. Let me first detect running servers...
[Runs: detectDevServers()]
[Output: Found server on port 3001]
I found your dev server running on http://localhost:3001

[Writes custom automation script to /tmp/playwright-test-marketing.js with URL parameterized]
[Runs: cd $SKILL_DIR && node run.js /tmp/playwright-test-marketing.js]
[Shows results with screenshots from /tmp/]
```

```
User: "Check if login redirects correctly"

Claude: I'll test the login flow. First, let me check for running servers...
[Runs: detectDevServers()]
[Output: Found servers on ports 3000 and 3001]
I found 2 dev servers. Which one should I test?
- http://localhost:3000
- http://localhost:3001

User: "Use 3001"

[Writes login automation to /tmp/playwright-test-login.js]
[Runs: cd $SKILL_DIR && node run.js /tmp/playwright-test-login.js]
[Reports: ✅ Login successful, redirected to /dashboard]
```

## Best Practices

Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.

- Keep the imported skill grounded in the upstream repository; do not invent steps that the source material cannot support.
- Prefer the smallest useful set of support files so the workflow stays auditable and fast to review.
- Keep provenance, source commit, and imported file paths visible in notes and PR descriptions.
- Point directly at the copied upstream files that justify the workflow instead of relying on generic review boilerplate.
- Treat generated examples as scaffolding; adapt them to the concrete task before execution.
- Route to a stronger native skill when architecture, debugging, design, or security concerns become dominant.



## Troubleshooting

### Problem: The operator skipped the imported context and answered too generically

**Symptoms:** The result ignores the upstream workflow in `plugins/antigravity-awesome-skills-claude/skills/playwright-skill`, fails to mention provenance, or does not use any copied source files at all.
**Solution:** Re-open `metadata.json`, `ORIGIN.md`, and the most relevant copied upstream files. Check the `external_source` block first, then restate the provenance before continuing.

### Problem: The imported workflow feels incomplete during review

**Symptoms:** Reviewers can see the generated `SKILL.md`, but they cannot quickly tell which references, examples, or scripts matter for the current task.
**Solution:** Point at the exact copied references, examples, scripts, or assets that justify the path you took. If the gap is still real, record it in the PR instead of hiding it.

### Problem: The task drifted into a different specialization

**Symptoms:** The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better.
**Solution:** Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.

### Imported Troubleshooting Notes

#### Imported: Troubleshooting

**Playwright not installed:**

```bash
cd $SKILL_DIR && npm run setup
```

**Module not found:**
Ensure running from skill directory via `run.js` wrapper

**Browser doesn't open:**
Check `headless: false` and ensure display available

**Element not found:**
Add wait: `await page.waitForSelector('.element', { timeout: 10000 })`

### Imported Reference Notes

#### Imported: Execution Pattern

**Step 1: Detect dev servers (for localhost testing)**

```bash
cd $SKILL_DIR && node -e "require('./lib/helpers').detectDevServers().then(s => console.log(JSON.stringify(s)))"
```

**Step 2: Write test script to /tmp with URL parameter**

```javascript
// /tmp/playwright-test-page.js
const { chromium } = require('playwright');

// Parameterized URL (detected or user-provided)
const TARGET_URL = 'http://localhost:3001'; // <-- Auto-detected or from user

(async () => {
  const browser = await chromium.launch({ headless: false });
  const page = await browser.newPage();

  await page.goto(TARGET_URL);
  console.log('Page loaded:', await page.title());

  await page.screenshot({ path: '/tmp/screenshot.png', fullPage: true });
  console.log('📸 Screenshot saved to /tmp/screenshot.png');

  await browser.close();
})();
```

**Step 3: Execute from skill directory**

```bash
cd $SKILL_DIR && node run.js /tmp/playwright-test-page.js
```

#### Imported: Common Patterns

### Test a Page (Multiple Viewports)

```javascript
// /tmp/playwright-test-responsive.js
const { chromium } = require('playwright');

const TARGET_URL = 'http://localhost:3001'; // Auto-detected

(async () => {
  const browser = await chromium.launch({ headless: false, slowMo: 100 });
  const page = await browser.newPage();

  // Desktop test
  await page.setViewportSize({ width: 1920, height: 1080 });
  await page.goto(TARGET_URL);
  console.log('Desktop - Title:', await page.title());
  await page.screenshot({ path: '/tmp/desktop.png', fullPage: true });

  // Mobile test
  await page.setViewportSize({ width: 375, height: 667 });
  await page.screenshot({ path: '/tmp/mobile.png', fullPage: true });

  await browser.close();
})();
```

### Test Login Flow

```javascript
// /tmp/playwright-test-login.js
const { chromium } = require('playwright');

const TARGET_URL = 'http://localhost:3001'; // Auto-detected

(async () => {
  const browser = await chromium.launch({ headless: false });
  const page = await browser.newPage();

  await page.goto(`${TARGET_URL}/login`);

  await page.fill('input[name="email"]', 'test@example.com');
  await page.fill('input[name="password"]', 'password123');
  await page.click('button[type="submit"]');

  // Wait for redirect
  await page.waitForURL('**/dashboard');
  console.log('✅ Login successful, redirected to dashboard');

  await browser.close();
})();
```

### Fill and Submit Form

```javascript
// /tmp/playwright-test-form.js
const { chromium } = require('playwright');

const TARGET_URL = 'http://localhost:3001'; // Auto-detected

(async () => {
  const browser = await chromium.launch({ headless: false, slowMo: 50 });
  const page = await browser.newPage();

  await page.goto(`${TARGET_URL}/contact`);

  await page.fill('input[name="name"]', 'John Doe');
  await page.fill('input[name="email"]', 'john@example.com');
  await page.fill('textarea[name="message"]', 'Test message');
  await page.click('button[type="submit"]');

  // Verify submission
  await page.waitForSelector('.success-message');
  console.log('✅ Form submitted successfully');

  await browser.close();
})();
```

### Check for Broken Links

```javascript
const { chromium } = require('playwright');

(async () => {
  const browser = await chromium.launch({ headless: false });
  const page = await browser.newPage();

  await page.goto('http://localhost:3000');

  const links = await page.locator('a[href^="http"]').all();
  const results = { working: 0, broken: [] };

  for (const link of links) {
    const href = await link.getAttribute('href');
    try {
      const response = await page.request.head(href);
      if (response.ok()) {
        results.working++;
      } else {
        results.broken.push({ url: href, status: response.status() });
      }
    } catch (e) {
      results.broken.push({ url: href, error: e.message });
    }
  }

  console.log(`✅ Working links: ${results.working}`);
  console.log(`❌ Broken links:`, results.broken);

  await browser.close();
})();
```

### Take Screenshot with Error Handling

```javascript
const { chromium } = require('playwright');

(async () => {
  const browser = await chromium.launch({ headless: false });
  const page = await browser.newPage();

  try {
    await page.goto('http://localhost:3000', {
      waitUntil: 'networkidle',
      timeout: 10000,
    });

    await page.screenshot({
      path: '/tmp/screenshot.png',
      fullPage: true,
    });

    console.log('📸 Screenshot saved to /tmp/screenshot.png');
  } catch (error) {
    console.error('❌ Error:', error.message);
  } finally {
    await browser.close();
  }
})();
```

### Test Responsive Design

```javascript
// /tmp/playwright-test-responsive-full.js
const { chromium } = require('playwright');

const TARGET_URL = 'http://localhost:3001'; // Auto-detected

(async () => {
  const browser = await chromium.launch({ headless: false });
  const page = await browser.newPage();

  const viewports = [
    { name: 'Desktop', width: 1920, height: 1080 },
    { name: 'Tablet', width: 768, height: 1024 },
    { name: 'Mobile', width: 375, height: 667 },
  ];

  for (const viewport of viewports) {
    console.log(
      `Testing ${viewport.name} (${viewport.width}x${viewport.height})`,
    );

    await page.setViewportSize({
      width: viewport.width,
      height: viewport.height,
    });

    await page.goto(TARGET_URL);
    await page.waitForTimeout(1000);

    await page.screenshot({
      path: `/tmp/${viewport.name.toLowerCase()}.png`,
      fullPage: true,
    });
  }

  console.log('✅ All viewports tested');
  await browser.close();
})();
```

#### Imported: Inline Execution (Simple Tasks)

For quick one-off tasks, you can execute code inline without creating files:

```bash
# Take a quick screenshot
cd $SKILL_DIR && node run.js "
const browser = await chromium.launch({ headless: false });
const page = await browser.newPage();
await page.goto('http://localhost:3001');
await page.screenshot({ path: '/tmp/quick-screenshot.png', fullPage: true });
console.log('Screenshot saved');
await browser.close();
"
```

**When to use inline vs files:**

- **Inline**: Quick one-off tasks (screenshot, check if element exists, get page title)
- **Files**: Complex tests, responsive design checks, anything user might want to re-run

#### Imported: Available Helpers

Optional utility functions in `lib/helpers.js`:

```javascript
const helpers = require('./lib/helpers');

// Detect running dev servers (CRITICAL - use this first!)
const servers = await helpers.detectDevServers();
console.log('Found servers:', servers);

// Safe click with retry
await helpers.safeClick(page, 'button.submit', { retries: 3 });

// Safe type with clear
await helpers.safeType(page, '#username', 'testuser');

// Take timestamped screenshot
await helpers.takeScreenshot(page, 'test-result');

// Handle cookie banners
await helpers.handleCookieBanner(page);

// Extract table data
const data = await helpers.extractTableData(page, 'table.results');
```

See `lib/helpers.js` for full list.

#### Imported: Custom HTTP Headers

Configure custom headers for all HTTP requests via environment variables. Useful for:

- Identifying automated traffic to your backend
- Getting LLM-optimized responses (e.g., plain text errors instead of styled HTML)
- Adding authentication tokens globally

### Configuration

**Single header (common case):**

```bash
PW_HEADER_NAME=X-Automated-By PW_HEADER_VALUE=playwright-skill \
  cd $SKILL_DIR && node run.js /tmp/my-script.js
```

**Multiple headers (JSON format):**

```bash
PW_EXTRA_HEADERS='{"X-Automated-By":"playwright-skill","X-Debug":"true"}' \
  cd $SKILL_DIR && node run.js /tmp/my-script.js
```

### How It Works

Headers are automatically applied when using `helpers.createContext()`:

```javascript
const context = await helpers.createContext(browser);
const page = await context.newPage();
// All requests from this page include your custom headers
```

For scripts using raw Playwright API, use the injected `getContextOptionsWithHeaders()`:

```javascript
const context = await browser.newContext(
  getContextOptionsWithHeaders({ viewport: { width: 1920, height: 1080 } }),
);
```

#### Imported: Tips

- **CRITICAL: Detect servers FIRST** - Always run `detectDevServers()` before writing test code for localhost testing
- **Custom headers** - Use `PW_HEADER_NAME`/`PW_HEADER_VALUE` env vars to identify automated traffic to your backend
- **Use /tmp for test files** - Write to `/tmp/playwright-test-*.js`, never to skill directory or user's project
- **Parameterize URLs** - Put detected/provided URL in a `TARGET_URL` constant at the top of every script
- **DEFAULT: Visible browser** - Always use `headless: false` unless user explicitly asks for headless mode
- **Headless mode** - Only use `headless: true` when user specifically requests "headless" or "background" execution
- **Slow down:** Use `slowMo: 100` to make actions visible and easier to follow
- **Wait strategies:** Use `waitForURL`, `waitForSelector`, `waitForLoadState` instead of fixed timeouts
- **Error handling:** Always use try-catch for robust automation
- **Console output:** Use `console.log()` to track progress and show what's happening

#### Imported: Notes

- Each automation is custom-written for your specific request
- Not limited to pre-built scripts - any browser task possible
- Auto-detects running dev servers to eliminate hardcoded URLs
- Test scripts written to `/tmp` for automatic cleanup (no clutter)
- Code executes reliably with proper module resolution via `run.js`
- Progressive disclosure - API_REFERENCE.md loaded only when advanced features needed

#### Imported: Limitations

- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
