What core-agent-browser does

core-agent-browser describes how to control a browser from the agent-browser CLI: open a page, inspect interactive controls, fill fields, click buttons, and check what happened. A page snapshot assigns references such as @e1 to elements for later commands.

For Rust and crate research, the listed priority is rust-learner, then the actionbook MCP, with direct agent-browser use reserved for sites without prepared selectors or tasks involving interactive checks, screenshots, or form entry. The skill is marked for internal use and is not intended for direct user invocation. The agent-browser command must be available in the environment.

What it helps with

  • inspect a page’s interactive controls
  • fill and submit a browser form
  • check a page after navigation or DOM changes
  • save a screenshot of a page

Example prompts for the agent

  • Open <url> with agent-browser, inspect the controls, and click the button needed for this task.
  • Fill in the form with agent-browser, submit it, then inspect the updated page.
  • Save a full-page screenshot as path.png.
