About cmux-browser

cmux-browser
End-user browser automation with cmux
Cmux-browser is an agent skill for automating a browser inside cmux, the macOS app. It is for opening sites, inspecting or interacting with browser surfaces, waiting for the page to reach a state, and extracting data from it. The skill begins by telling the agent to check the cmux binary that will run before it gives any exact command, using the browser help and version commands, because the command shapes depend on the version. It separates two kinds of command. Commands that create a browser surface, such as open, open-split and new, can be scoped to the workspace and do not need a surface handle. Every other command, including navigation, inspection, interaction, tabs and state, acts on an existing surface, and must receive that surface's handle explicitly with a surface flag or as the first positional token. For scripts, the skill recommends the flag form because it makes the target clear. It is listed on skills.sh as part of the manaflow-ai cmux project, and its security audit shows one warning from Snyk.
