Agent Browser

Browser Automation with agent-browser

Runtime Setup (MANDATORY — run before any command)

Before executing ANY agent-browser command, you MUST ensure the runtime is installed:

1. Check if runtime/version.txt exists in this skill's directory
2. If it does NOT exist, run the bootstrap script:
   • macOS / Linux: bash "<SKILL_DIR>/bootstrap.sh"
   • Windows: powershell -ExecutionPolicy Bypass -File "<SKILL_DIR>/bootstrap.ps1" This downloads ~230MB runtime (one-time). Tell the user: "正在首次准备浏览器环境，请稍候..."
3. After bootstrap, ALL commands must go through the wrapper:
   • macOS / Linux: "<SKILL_DIR>/agent-browser" <command> [args...]
   • Windows: "<SKILL_DIR>/agent-browser.cmd" <command> [args...]

Replace <SKILL_DIR> with the absolute path to this skill's directory.

NEVER call agent-browser directly without the skill directory prefix. Always use "<SKILL_DIR>/agent-browser" (macOS/Linux) or "<SKILL_DIR>/agent-browser.cmd" (Windows).

Quick start

"<SKILL_DIR>/agent-browser" open <url>        # Navigate to page
"<SKILL_DIR>/agent-browser" snapshot -i       # Get interactive elements with refs
"<SKILL_DIR>/agent-browser" click @e1         # Click element by ref
"<SKILL_DIR>/agent-browser" fill @e2 "text"   # Fill input by ref
"<SKILL_DIR>/agent-browser" close             # Close browser

Core workflow

1. Navigate: "<SKILL_DIR>/agent-browser" open <url>
2. Snapshot: "<SKILL_DIR>/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

Command Reference

Below, AB is shorthand for "<SKILL_DIR>/agent-browser". Replace <SKILL_DIR> with the absolute path to this skill's directory in every invocation.

"<SKILL_DIR>/agent-browser" connect 9222    # Connect via CDP port

Snapshot (page analysis)

"<SKILL_DIR>/agent-browser" snapshot            # Full accessibility tree
"<SKILL_DIR>/agent-browser" snapshot -i         # Interactive elements only (recommended)
"<SKILL_DIR>/agent-browser" snapshot -c         # Compact output
"<SKILL_DIR>/agent-browser" snapshot -d 3       # Limit depth to 3
"<SKILL_DIR>/agent-browser" snapshot -s "#main" # Scope to CSS selector
