Add containerized agent execution with Apple Container
- Agents run in isolated Linux VMs via Apple Container - All groups get Bash access (safe - sandboxed in container) - Browser automation via agent-browser + Chromium - Per-group configurable additional directory mounts - File-based IPC for messages and scheduled tasks - Container image with Node.js 22, Chromium, agent-browser Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

description: Automates browser interactions for web testing, form filling, screenshots, and data extraction. Use when the user needs to navigate websites, interact with web pages, fill forms, take screenshots, test web applications, or extract information from web pages.

# Browser Automation with agent-browser
|
||||
|
||||
## Quick start
|
||||
|
||||
```bash
|
||||
agent-browser open <url> # Navigate to page
|
||||
agent-browser snapshot -i # Get interactive elements with refs
|
||||
agent-browser click @e1 # Click element by ref
|
||||
agent-browser fill @e2 "text" # Fill input by ref
|
||||
agent-browser close # Close browser
|
||||
```
|
||||
|
||||
## Core workflow
|
||||
|
||||
1. Navigate: `agent-browser open <url>`
|
||||
2. Snapshot: `agent-browser snapshot -i` (returns elements with refs like `@e1`, `@e2`)
|
||||
3. Interact using refs from the snapshot
|
||||
4. Re-snapshot after navigation or significant DOM changes
|
||||
|
||||
## Commands
|
||||
|
||||
### Navigation
|
||||
|
||||
```bash
|
||||
agent-browser open <url> # Navigate to URL
|
||||
agent-browser back # Go back
|
||||
agent-browser forward # Go forward
|
||||
