Skill Details

SKILL.md

Autonomous browser control with Cowork-style skill recording. Use when user requests "control my screen", "record workflow", "verify Lovable", "test scrapers", "debug DOM", "autonomous testing", or any browser automation task. Uses CDP + Accessibility Tree for 10x faster, 100% reliable element targeting. NO screenshots.

Overview

# Screen Control Operator V3

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

Core Advantages Over Claude Cowork

| Feature | Claude Cowork | Screen Control Operator V3 |

|---------|---------------|---------------------------|

| Vision Method | Screenshots | CDP + Accessibility Tree |

| Speed | 1-5 seconds | 50-200ms (10x faster) |

| Cost | Vision tokens ($$$) | Text tokens only ($) |

| Reliability | ~85% OCR | 100% semantic queries |

| Skill Recording | βœ… Yes | βœ… Yes |

| Parallel Execution | βœ… Yes | βœ… Yes |

| Domain Skills | Generic | Foreclosure-specific |

| Smart Router | N/A | 90% FREE tier |

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

```python

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

```bash

# Record new skill

python screen_control_operator_v3.py record \

--name "BECA Deep Search" \

--domain foreclosure \

--output skills/beca_deep.json \

--start-url "https://vmatrix1.brevardclerk.us/beca/"

# Play skill with variables

python screen_control_operator_v3.py play \

--skill skills/beca_deep.json \

--vars '{"case_number": "2025-CA-001234"}'

# Pre-built skills

python screen_control_operator_v3.py beca --case "2025-CA-001234"

python screen_control_operator_v3.py bcpao --parcel "12-34-56-78-90"

# Inspect page DOM (NOT screenshot)

python screen_control_operator_v3.py inspect \

--url "https://example.com" \

--output structure.json

```

Pre-Built Foreclosure Skills

| Skill ID | Name | Variables | Description |

|----------|------|-----------|-------------|

| beca_lookup_001 | BECA Case Lookup | case_number | Search BECA, extract judgment |

| bcpao_lookup_001 | BCPAO Property | parcel_id | Get property details, photo |

| acclaimweb_lien_001 | Lien Search | party_name | Search recorded liens |

| realforeclose_list_001 | Auction List | auction_date | Get auction calendar |

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

```json

{

"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:

```python

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):

```python

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:

```python

selector = operator.find_element_semantic("search button")

# Returns: "[data-testid='search-btn']" or "#search-button" or similar

```

Smart Router Integration

| Operation | Model Tier | Cost |

|-----------|-----------|------|

| Page navigation | FREE (Gemini) | $0 |

| Element finding | FREE (Gemini) | $0 |

| Skill recording | FREE (Gemini) | $0 |

| Skill playback | FREE (Gemini) | $0 |

| Error recovery | BALANCED (Sonnet) | $ |

Result: 95%+ operations in FREE tier

GitHub Actions Integration

```yaml

# .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

```bash

pip install playwright --break-system-packages

playwright install chromium

```
