Core Workflow

Every browser automation follows this pattern:

1. Navigate: mybrowser-skill browser_go_to_url --url <url>
2. Snapshot: mybrowser-skill browser_snapshot (get indexed element refs)
3. Interact: Use element index to click, fill, select
4. Re-snapshot: After navigation or DOM changes, get fresh refs

mybrowser-skill browser_go_to_url --url https://example.com/form
mybrowser-skill browser_snapshot
# Output includes element indices: [1] input "email", [2] input "password", [3] button "Submit"

mybrowser-skill browser_input_text --index 1 --text "user@example.com"
mybrowser-skill browser_input_text --index 2 --text "password123"
mybrowser-skill browser_click_element --index 3
mybrowser-skill browser_wait --seconds 2
mybrowser-skill browser_snapshot  # Check result

Common Patterns

Form Submission

mybrowser-skill browser_go_to_url --url https://example.com/signup
mybrowser-skill browser_snapshot
mybrowser-skill browser_input_text --index 1 --text "Jane Doe"
mybrowser-skill browser_input_text --index 2 --text "jane@example.com"
mybrowser-skill browser_select_dropdown_option --index 3 --text "California"
mybrowser-skill browser_check_op --index 4 --value
mybrowser-skill browser_click_element --index 5
mybrowser-skill browser_wait --seconds 2
mybrowser-skill browser_snapshot  # Verify result

Data Extraction

mybrowser-skill browser_go_to_url --url https://example.com/products
mybrowser-skill browser_snapshot
mybrowser-skill browser_get_info --type text --index 5    # Get specific element text
mybrowser-skill browser_markdownify                        # Get full page as markdown

Infinite Scroll Pages

mybrowser-skill browser_go_to_url --url https://example.com/feed
mybrowser-skill browser_scroll_to_bottom     # Trigger lazy loading
mybrowser-skill browser_wait --seconds 2     # Wait for content
mybrowser-skill browser_snapshot             # Get updated content

Element Index Lifecycle (Important)

Element indices are invalidated when the page changes. Always re-snapshot after:

• Clicking links or buttons that navigate
• Form submissions
• Dynamic content loading (dropdowns, modals, AJAX)

mybrowser-skill browser_click_element --index 5   # May navigate to new page
mybrowser-skill browser_snapshot                   # MUST re-snapshot
mybrowser-skill browser_click_element --index 1   # Use new indices
