Browser-Use Automation Skill
You are an expert in browser automation using browser-use, a powerful CLI tool designed for persistent, multi-session browser automation. When the user asks you to automate complex browser workflows, manage sessions, or perform long-running automation tasks, follow these detailed instructions.
Core Principles
Persistent sessions -- Maintain browser state across multiple automation runs.Multi-session support -- Run multiple isolated browser sessions in parallel.Flexible browser modes -- Support for Chromium (headless), Real (headed), and Remote browser instances.Cookie management -- Export, import, and manage cookies for authentication persistence.JavaScript execution -- Execute custom JavaScript in page context for advanced automation.
Installation
npm install -g browser-use
npx browser-use --version
pip install browser-use

Cookie-Based Authentication Persistence #!/bin/bash
SESSION_NAME="authenticated-user"
if browser-use session list | grep -q "$SESSION_NAME " ; then
echo "Using existing authenticated session"
browser-use session attach --name "$SESSION_NAME "
else
echo "Creating new authenticated session"
browser-use session create --name "$SESSION_NAME " --persist
browser-use navigate --url "https://app.example.com/login"
browser-use type --selector "#email" --text "user@example.com"
browser-use type --selector "#password" --text "$PASSWORD "
browser-use click --selector "button[type='submit']"
browser-use wait --selector ".dashboard" --timeout 10000
browser-use cookies export --session "$SESSION_NAME " --output auth-cookies.json
echo "Session authenticated and cookies saved"
fi
browser-use navigate --url "https://app.example.com/dashboard"
JavaScript Execution
Execute JavaScript in Page Context
browser-use execute --script "return document.title"
browser-use execute --script "return arguments[0] + arguments[1]" --args "[5, 10]"
browser-use execute --script "return document.querySelectorAll('.item').length" --output item-count.json
browser-use execute --script-file ./custom-script.js
Example Script File (custom-script.js):
const products = Array .from (document .querySelectorAll ('.product-card' )).map (card =>return {
name : card.querySelector ('.product-name' )?.textContent .trim (),
price : card.querySelector ('.product-price' )?.textContent .trim (),
image : card.querySelector ('.product-image' )?.src ,
rating : card.querySelector ('.rating' )?.getAttribute ('data-rating' ),
available : !card.querySelector ('.out-of-stock' )
};
});
return { products, total : products.length };
browser-use execute --script-file ./extract-products.js --output products.json

return new Promise(resolve => {
const check = () => {
if (document.querySelectorAll('.loaded-item').length >= 10) {
resolve(true);
} else {
setTimeout(check, 100);
}
};
check();
});
"
browser-use execute --script "
document.querySelectorAll('.annoying-popup').forEach(el => el.remove());
document.body.style.backgroundColor = '#f0f0f0';
return 'Page modified';
"
browser-use execute --script "
const event = new Event('custom-event');

Advanced Patterns
Long-Running Monitoring #!/bin/bash
SESSION="monitor-session"
INTERVAL=300
browser-use session create --name "$SESSION " --persist
browser-use navigate --url "https://status.example.com"
while true ; do
STATUS=$(browser-use execute --script "
const statusEl = document.querySelector('.status-indicator');
return {
status: statusEl.textContent,
color: getComputedStyle(statusEl).backgroundColor,
timestamp: new Date().toISOString()
};
" )
echo "$(date) : $STATUS " >> monitor.log
if echo "$STATUS " | grep -q "down" ; then
browser-use snapshot --output "failure-$(date +%s) .png"

Parallel Session Processing async function processMultipleAccounts (accounts : Array <{ email: string ; password: string }>const sessions = await Promise .all (
accounts.map (async (account, index) => {
const sessionName = `account-${index} ` ;
const browser = new BrowserAutomation (sessionName);
await browser.start ();
await browser.navigate ('https://app.example.com/login' );
await browser.executeScript ((email : string , password : string {
(document .querySelector ('#email' ) as HTMLInputElement ).value = email;
(document .querySelector ('#password' ) as HTMLInputElement ).value = password;
(document .querySelector ('button[type="submit"]' ) as HTMLButtonElement ).click ();
}, account.email , account.password );
await new Promise (resolve =>setTimeout (resolve, 3000 ));
await browser.saveAuthCookies (`./cookies-${index} .json` );
return browser;
})
);
return sessions;
}
Best Practices
Use persistent sessions for workflows requiring authentication state.Export cookies regularly to recover from session failures.Name sessions descriptively to identify purpose when listing sessions.Clean up sessions after completion to avoid resource leaks.Use JavaScript execution for complex data extraction that CLI commands can't handle.Monitor network requests to verify API interactions and troubleshoot issues.Implement retry logic for transient failures in long-running automations.Use multi-session parallelism to process multiple accounts or sites simultaneously.Validate session state before critical operations to ensure authentication persists.Document session requirements for each automation workflow.
Anti-Patterns to Avoid
Not cleaning up sessions -- Leads to resource exhaustion.Hardcoding credentials -- Use environment variables or secure vaults.Ignoring session expiration -- Implement cookie refresh or re-authentication.Over-reliance on delays -- Use event-based waiting instead of fixed sleeps.Single session for parallel tasks -- Creates race conditions and state conflicts.Not backing up cookies -- Session loss requires re-authentication.Ignoring network errors -- Implement proper error handling and retries.Mixing session contexts -- Keep sessions isolated to avoid state bleeding.Not validating JavaScript results -- Always check return values for expected structure.Running too many parallel sessions -- Respect system resources and rate limits.
Debugging and Troubleshooting
Enable Debug Mode
browser-use --debug navigate --url "https://example.com"
browser-use --console-output ./console.log navigate --url "https://example.com"
browser-use --screenshot-on-error ./errors/ navigate --url "https://example.com"
browser-use start --mode real --devtools
Session Recovery
browser-use session health --name "my-session"
browser-use session recover --name "my-session" --backup ./session-backup.json
browser-use session delete --name "my-session" --force
