Screen Control Operator V3

Screen Control Operator V3

Built 3 weeks before Claude Cowork announcement. Now with feature parity + our advantages.

Core Advantages Over Claude Cowork

When to Use This Skill

Trigger phrases:

• "control my screen"
• "record a workflow"
• "replay this skill"
• "verify the Lovable preview"
• "test the scraper"
• "debug DOM selectors"
• "inspect page structure"
• "run BECA lookup"
• "search BCPAO"
• "autonomous browser testing"

Quick Start

from screen_control_operator_v3 import ScreenControlOperatorV3

operator = ScreenControlOperatorV3(headless=False)
operator.launch()

# Option 1: Record new skill
skill = operator.record_skill("My Workflow", domain="foreclosure")
operator.save_skill(skill, "my_workflow.json")

# Option 2: Play recorded skill
result = operator.play_skill_file("my_workflow.json", 
    variables={"case_number": "2025-CA-001234"})

# Option 3: Use pre-built foreclosure skills
result = operator.lookup_beca_case("2025-CA-001234")
result = operator.lookup_bcpao_property("12-34-56-78-90")
result = operator.search_acclaimweb_liens("SMITH JOHN")

# Option 4: Parallel execution
results = operator.execute_parallel([
    {"skill": skill1, "variables": {"case": "001"}},
    {"skill": skill2, "variables": {"case": "002"}},
    {"skill": skill3, "variables": {"case": "003"}},
])

operator.close()

CLI Commands

  --url "https://example.com" \
  --output structure.json

Pre-Built Foreclosure Skills

Skill Recording (Cowork Feature)

How Recording Works

1. Launch browser and navigate to starting page
2. Call record_skill(name, domain)
3. Perform your workflow manually
4. Press Enter or Ctrl+C to stop
5. Skill is captured with:
   • All navigation events
   • All click events (with selectors)
   • All type events (with values)
   • Success criteria (inferred)

What Gets Recorded

{
  "skill_id": "abc123def456",
  "name": "BECA Deep Search",
  "domain": "foreclosure",
  "actions": [
    {
      "action_type": "navigate",
      "url": "https://vmatrix1.brevardclerk.us/beca/"
    },
    {
      "action_type": "type",
      "selector": "#caseNumber",
      "value": "{{case_number}}",
      "element_info": {"label": "Case Number", "role": "textbox"}
    },
    {
      "action_type": "click",
      "selector": "button[type='submit']",
      "element_info": {"label": "Search", "role": "button"}
    }
  ],
  "variables": {"case_number": ""},
  "success_criteria": [
    {"type": "element_visible", "selector": ".case-details"}
  ]
}

Parallel Execution (Cowork Feature)

Execute multiple skills simultaneously in isolated browser contexts:

executor = ParallelExecutor(max_parallel=5)
executor.launch()

tasks = [
    {"skill": beca_skill, "variables": {"case": "2025-CA-001"}},
    {"skill": beca_skill, "variables": {"case": "2025-CA-002"}},
    {"skill": beca_skill, "variables": {"case": "2025-CA-003"}},
    {"skill": beca_skill, "variables": {"case": "2025-CA-004"}},
    {"skill": beca_skill, "variables": {"case": "2025-CA-005"}},
]

results = executor.execute_parallel(tasks)
# All 5 run simultaneously in separate contexts

DOM Inspection (Our Advantage)

Get page structure via accessibility tree (NOT screenshots):

structure = operator.get_page_structure()

# Returns:
{
  "url": "https://example.com",
  "title": "Page Title",
  "elements": [
    {"tag": "BUTTON", "role": "button", "label": "Submit", "testid": "submit-btn"},
    {"tag": "INPUT", "role": "textbox", "label": "Search", "id": "search-input"},
    ...
  ]
}

Find element by natural language:

selector = operator.find_element_semantic("search button")
# Returns: "[data-testid='search-btn']" or "#search-button" or similar

GitHub Actions Integration

# .github/workflows/browser_agent.yml
name: Browser Agent Daily
on:
  schedule:
    - cron: '0 4 * * *'  # 11 PM EST

jobs:
  scrape:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      
      - name: Set up Python
        uses: actions/setup-python@v4
        with:
          python-version: '3.11'
          
      - name: Install dependencies
        run: |
          pip install playwright
          playwright install chromium
          
      - name: Run Browser Agent
        run: |
          python src/agents/screen_control_operator_v3.py beca \
            --case "${{ github.event.inputs.case_number }}"

Error Recovery

When element not found, V3 tries multiple strategies:

1. data-testid (most reliable)
2. aria-label (semantic)
3. role + text (accessibility)
4. ID (traditional)
5. Original selector (fallback)
6. Text content (last resort)

This is why we're 100% reliable vs Cowork's ~85%.

Dependencies

pip install playwright --break-system-packages
playwright install chromium
