Core agent-browser usage guide. Read this before running any agent-browser commands. Covers the snapshot-and-ref workflow, navigating pages, interacting with elements (click, fill, type, select), extracting text and data, taking screenshots, managing tabs, handling forms and auth, waiting for content, running multiple browser sessions in parallel, and troubleshooting common failures. Use when the user asks to interact with a website, fill a form, click something, extract data, take a screenshot, log into a site, test a web app, or automate any browser task.

# agent-browser core

agent-browser drives Chrome over CDP from the command line. A snapshot returns the page's accessibility tree with a compact `@eN` ref for each element, and you act on those refs. This guide covers the loop and the common web tasks. Detailed flags, edge cases, and specialized workflows live in references and other skills; [Load more when you need it](#load-more-when-you-need-it) says which one to load for what.

## Always use your own session

Before your first command, get a session name for the task. It is stable for the worktree, so running it again prints the same name:

```bash
agent-browser session id --scope worktree --prefix task   # prints a name such as task-be5442ae6b6b
```

Pass that name with `--session <name>` on every command. Many agent harnesses run each command in a new shell, so an `export AGENT_BROWSER_SESSION=...` is gone by the next command, which then runs in the default session. Export the variable only when every command runs in the same shell.
