agent-browser

Fast browser automation CLI for AI agents. Chrome/Chromium via CDP with accessibility-tree snapshots and compact @eN element refs.

Install: npm i -g agent-browser && agent-browser install

Start here

This file is a discovery stub, not the usage guide. Before running any agent-browser command, load the actual workflow content from the CLI:

bash
agent-browser skills get core             # start here: the loop, waits, common tasks, troubleshooting

The core guide ends with a table of references to load for detailed commands and flags. Use agent-browser skills get core --full only when you need every reference at once; it is several times larger.

The CLI serves skill content that matches the installed version. This stub cannot change between releases, which is why it only points at skills get core.
