Browser Agent Automation

Choose approach

Approach	Best for
Playwright MCP	Existing Playwright tests; IDE agents
Browser-Use (Python)	Greenfield "do this on the site" tasks
Cursor IDE browser MCP	Interactive debugging in Cursor

Default: Playwright MCP in Cursor; Browser-Use for standalone Python agents.

Safety rules

Never automate login without explicit user consent in session
Respect robots.txt and site ToS for bulk scraping
Cap steps (e.g. 30 actions) and timeout per navigation
Do not exfiltrate cookies/localStorage to logs

Workflow

- [ ] Define goal and success condition (URL, element, downloaded file)
- [ ] Start from known URL; avoid open-ended googling
- [ ] Use accessibility snapshots before clicks (prefer refs/roles)
- [ ] Verify after each critical action (screenshot or DOM check)
- [ ] On failure: one alternate strategy, then stop and report

Playwright MCP (Cursor)

List tabs → navigate → lock → snapshot
Interact via dedicated browser tools (not raw CDP input)
Unlock when done

Reliability patterns

Wait for network idle or specific selector, not fixed sleeps
Idempotent clicks: confirm state changed
For forms: fill → validate → submit → verify confirmation text

Anti-patterns

Brittle CSS selectors when role+name available
Infinite retry loops on captcha/login walls
Storing credentials in skill files or repo

Report blockers (captcha, 2FA) and ask user to take over.
