Browser Skill
Provides server-side headless browser automation using agent-browser CLI (Playwright/Chromium backend):
- Navigate to URLs (with auto-snapshot and bot detection)
- Snapshot accessibility tree with element references (e.g.,
@e5)
- Click elements by reference
- Type text into input fields
- Scroll up/down
- Navigate back in history
- Press keyboard keys
- Take full-page screenshots (base64 PNG)
- Execute JavaScript in page context
- Read console messages and JS errors
- Session isolation per
task_id
Use builtin_browser tool with fields:
operation: one of "navigate", "snapshot", "click", "type", "scroll", "back", "press", "screenshot", "eval", "console", "close"url: URL to navigate to (required for navigate)ref: Element reference from snapshot (e.g., @e5) for click/typetext: Text to type (for type) or key to press (for press)js: JavaScript expression to evaluate (required for eval)task_id: Session identifier (default: "default"); each task_id gets its own browser sessiondirection: Scroll direction "up" or "down" (default: "down")full: Full page screenshot "true"/"false" (default: "false")clear: Clear console/errors after reading "true"/"false"
Response format:
- Always return the result in a single message. When taking a screenshot, embed the base64 PNG inline in your reply via
 — do not split into multiple messages.
Notes:
- Requires
agent-browser CLI installed: npx agent-browser install --with-deps
- Each
task_id maintains an isolated browser session with persistent state
- Sessions auto-clean after 5 minutes of inactivity
- Element references from snapshot (e.g.,
@e5) are used for click/type — not CSS selectors
- For simple HTTP fetches, prefer
builtin_http_client (faster, lighter)
