Browser Use (skill)
Skill, agent skill, by browser-use
Assessment
The skill that lets an agent verify instead of assume: open the staging site, click through the flow, screenshot what broke. Worth having for checks and for research on dynamic pages, under the same patient-reader rules as any scraper.

Strengths
- A headless browser the agent drives: navigate, click, fill forms, read rendered pages, screenshot
- End-to-end checks of a deployed feature, not just the code
- Research on pages that need JavaScript to render
Limitations
- Slow and token-hungry compared with a direct fetch
- Every page it opens is a request from your address; politeness and authorisation rules apply
Browser Use connects a coding agent to a real browser session.[1] The agent can open a URL, read the page as rendered, click, type into forms, follow links and take screenshots, and it reports what it saw in plain words. It does not need to know a page's structure in advance; it looks, reads and acts.
What it is for
Verifying a feature end to end: sign up on the staging site, confirm the email link works, screenshot the dashboard, report the button that is below the fold on a phone. Research on pages that render with JavaScript, where a plain fetch sees nothing. Any task that today means a person opening a browser and clicking through.
Things to know
- It is the slowest, most expensive way to read a page. Use a direct fetch for static pages and save the browser for pages that need it.
- Every page it opens is a request from the machine it runs on. The rules for reading other people's sites hold: pace requests, take only what is needed, stop at a bot-protection page.[2]
- Keep it off production systems unless the task is explicitly to test them.
