I don't understand how "agent-browser" works.

Is it just the instructions? Where is the browsing executed? Locally with pupetter? Or it uses some service?

it's basically a cli for controlling a browser. the idea is that an agent like claude code would use it for validating something that it just did like changing something on the UI

What browser? My question comes from security, adding that skills just provides a line of bash, with no further info. I checked the .md file but it just lists a list of commands with agent-browser.

agent-browser is built on top of Playwright. Playwright uses a version of Chromium.

I was looking at this earlier. Has anyone used it? Is it useful compared to the Playwright MCP or Claude's Chrome plugin?

Agent browser is more lightweight than playwright mcp. Claude Chrome requires some manual setup, and works better in cases requires your actual browser not a headless one.
