Browser Automation

Use this skill when work requires real browser interaction instead of API-only lookups.

Core Workflow

1. Open target page:

• agent-browser open <url>

2. Capture interactive refs:

• agent-browser snapshot -i

3. Interact by ref:

• agent-browser click @e1
• agent-browser fill @e2 "value"

4. Re-snapshot after every navigation or significant DOM change:

• agent-browser snapshot -i

5. Capture result evidence:

• agent-browser screenshot --annotate <file.png>

Operational Rules

• Use agent-browser directly; do not use npx agent-browser.
• Prefer one named session for multi-step flows:
  • agent-browser --session <name> ...
• Use chained commands with && only when no intermediate output is needed.
• For commands that need refs (@e*), run snapshot -i first and use fresh refs.
• If page load is async-heavy, wait explicitly:
  • agent-browser wait --load networkidle
• For user-facing findings, include screenshots and the exact page URL.
• When a user asks to see/share a screenshot in Slack, use sendFiles with the screenshot path in files so the image is included in the active conversation.
• Never claim a screenshot was shared unless sendFiles returned success in this turn.
• If sendFiles is unavailable or file attachment fails, state the failure clearly and include the saved screenshot path or error instead of claiming success.

Common Patterns

Form flow

agent-browser --session demo open https://example.com/signup
agent-browser --session demo wait --load networkidle
agent-browser --session demo snapshot -i
agent-browser --session demo fill @e1 "user@example.com"
agent-browser --session demo click @e2
agent-browser --session demo wait --load networkidle
agent-browser --session demo screenshot --annotate /tmp/signup-result.png

Structured extraction

agent-browser open https://example.com
agent-browser snapshot --json > /tmp/page.json
agent-browser get text body > /tmp/page.txt
