+# Running Custom Playwright Code
+
+Use `run-code` to execute arbitrary Playwright code for advanced scenarios not covered by CLI commands.
+
+## Syntax
+
+```bash
+playwright-cli run-code "async page => {
+  // Your Playwright code here
+  // Access page.context() for browser context operations
+}"
+```
+
+## Geolocation
+
+```bash
+# Grant geolocation permission and set location
+playwright-cli run-code "async page => {
+  await page.context().grantPermissions(['geolocation']);
+  await page.context().setGeolocation({ latitude: 37.7749, longitude: -122.4194 });
+}"
+
+# Set location to London
+playwright-cli run-code "async page => {
+  await page.context().grantPermissions(['geolocation']);
+  await page.context().setGeolocation({ latitude: 51.5074, longitude: -0.1278 });
+}"
+
+# Clear geolocation override
+playwright-cli run-code "async page => {
+  await page.context().clearPermissions();
+}"
+```
+
+## Permissions
+
+```bash
+# Grant multiple permissions
+playwright-cli run-code "async page => {
+  await page.context().grantPermissions([
+    'geolocation',
+    'notifications',
+    'camera',
+    'microphone'
+  ]);
+}"
+
+# Grant permissions for specific origin
+playwright-cli run-code "async page => {
+  await page.context().grantPermissions(['clipboard-read'], {
+    origin: 'https://example.com'
+  });
+}"
+```
+
+## Media Emulation
+
+```bash
+# Emulate dark color scheme
+playwright-cli run-code "async page => {
+  await page.emulateMedia({ colorScheme: 'dark' });
+}"
+
+# Emulate light color scheme
+playwright-cli run-code "async page => {
+  await page.emulateMedia({ colorScheme: 'light' });
+}"
+
+# Emulate reduced motion
+playwright-cli run-code "async page => {
+  await page.emulateMedia({ reducedMotion: 'reduce' });
+}"
+
+# Emulate print media
+playwright-cli run-code "async page => {
+  await page.emulateMedia({ media: 'print' });
+}"
+```
+
+## Wait Strategies
+
+```bash
+# Wait for network idle
+playwright-cli run-code "async page => {
+  await page.waitForLoadState('networkidle');
+}"
+
+# Wait for specific element
+playwright-cli run-code "async page => {
+  await page.waitForSelector('.loading', { state: 'hidden' });
+}"
+
+# Wait for function to return true
+playwright-cli run-code "async page => {
+  await page.waitForFunction(() => window.appReady === true);
+}"
+
+# Wait with timeout
+playwright-cli run-code "async page => {
+  await page.waitForSelector('.result', { timeout: 10000 });
+}"
+```
+
+## Frames and Iframes
+
+```bash
+# Work with iframe
+playwright-cli run-code "async page => {
+  const frame = page.locator('iframe#my-iframe').contentFrame();
+  await frame.locator('button').click();
+}"
+
+# Get all frames
+playwright-cli run-code "async page => {
+  const frames = page.frames();
+  return frames.map(f => f.url());
+}"
+```
+
+## File Downloads
+
+```bash
+# Handle file download
+playwright-cli run-code "async page => {
+  const [download] = await Promise.all([
+    page.waitForEvent('download'),
+    page.click('a.download-link')
+  ]);
+  await download.saveAs('./downloaded-file.pdf');
+  return download.suggestedFilename();
+}"
+```
+
+## Clipboard
+
+```bash
+# Read clipboard (requires permission)
+playwright-cli run-code "async page => {
+  await page.context().grantPermissions(['clipboard-read']);
+  return await page.evaluate(() => navigator.clipboard.readText());
+}"
+
+# Write to clipboard
+playwright-cli run-code "async page => {
+  await page.evaluate(text => navigator.clipboard.writeText(text), 'Hello clipboard!');
+}"
+```
+
+## Page Information
+
+```bash
+# Get page title
+playwright-cli run-code "async page => {
+  return await page.title();
+}"
+
+# Get current URL
+playwright-cli run-code "async page => {
+  return page.url();
+}"
+
+# Get page content
+playwright-cli run-code "async page => {
+  return await page.content();
+}"
+
+# Get viewport size
+playwright-cli run-code "async page => {
+  return page.viewportSize();
+}"
+```
+
+## JavaScript Execution
+
+```bash
+# Execute JavaScript and return result
+playwright-cli run-code "async page => {
+  return await page.evaluate(() => {
+    return {
+      userAgent: navigator.userAgent,
+      language: navigator.language,
+      cookiesEnabled: navigator.cookieEnabled
+    };
+  });
+}"
+
+# Pass arguments to evaluate
+playwright-cli run-code "async page => {
+  const multiplier = 5;
+  return await page.evaluate(m => document.querySelectorAll('li').length * m, multiplier);
+}"
+```
+
+## Error Handling
+
+```bash
+# Try-catch in run-code
+playwright-cli run-code "async page => {
+  try {
+    await page.click('.maybe-missing', { timeout: 1000 });
+    return 'clicked';
+  } catch (e) {
+    return 'element not found';
+  }
+}"
+```
+
+## Complex Workflows
+
+```bash
+# Login and save state
+playwright-cli run-code "async page => {
+  await page.goto('https://example.com/login');
+  await page.fill('input[name=email]', 'user@example.com');
+  await page.fill('input[name=password]', 'secret');
+  await page.click('button[type=submit]');
+  await page.waitForURL('**/dashboard');
+  await page.context().storageState({ path: 'auth.json' });
+  return 'Login successful';
+}"
+
+# Scrape data from multiple pages
+playwright-cli run-code "async page => {
+  const results = [];
+  for (let i = 1; i <= 3; i++) {
+    await page.goto(\`https://example.com/page/\${i}\`);
+    const items = await page.locator('.item').allTextContents();
+    results.push(...items);
+  }
+  return results;
+}"
+```
