🛠️ Working with Agentic Primitives

How to Modify Chat Modes

Chat modes are specialized agent configurations that define behavior for specific roles. Each chat mode follows a structured format:

Adding a New Chat Mode

Create the chat mode file (e.g., analyzer.chatmode.md):

---
name: "Analyzer Agent"
role: "Data Analysis Specialist"
expertise: ["statistical_analysis", "pattern_recognition", "data_validation"]
quality_threshold: 7.5
output_format: "structured_json"
---

# Analyzer Agent Specialist

You are a data analysis specialist focusing on extracted product data quality and insights.

## Core Responsibilities
- Statistical analysis of extraction results
- Pattern recognition in product data
- Data validation and anomaly detection
- Performance metrics calculation

## Analysis Workflow
1. **Data Quality Assessment**
   - Check completeness scores
   - Validate data types and formats
   - Identify missing or inconsistent fields

2. **Pattern Analysis** 
   - Price distribution analysis
   - Category clustering insights
   - Seasonal trend detection

3. **Recommendations**
   - Optimization suggestions based on data patterns
   - Method performance recommendations
   - Quality improvement strategies

Register in primitive loader (utils/primitive_loader.py):

CHATMODE_FILES = [
    'planner.chatmode.md',
    'executor.chatmode.md', 
    'judge.chatmode.md',
    'analyzer.chatmode.md'  # Add your new chat mode
]

Test the new chat mode:

python -m pytest tests/test_primitives.py::TestAgenticPrimitives::test_chatmode_files_exist -v

Modifying Existing Chat Modes

Example: Enhancing the Executor Chat Mode

# In executor.chatmode.md, add new capability:

## Advanced Capabilities
- **Smart Retry Logic**: Exponential backoff with circuit breaker
- **Dynamic Method Selection**: Real-time performance adaptation
- **Content Validation**: On-the-fly data quality checks
- **Resource Optimization**: Memory and CPU usage monitoring

## New Execution Patterns
1. **Parallel Processing Mode**
   - Concurrent URL processing with rate limiting
   - Shared memory for performance tracking
   - Load balancing across methods

2. **Adaptive Extraction**
   - Real-time selector effectiveness monitoring
   - Automatic fallback chain optimization
   - Dynamic timeout adjustment

How to Update Agent Memory

The .memory.md file serves as persistent storage for agent learning. Here's how to work with it:

Memory Structure

# Darwin Agent Memory System

## Method Performance Tracking
- **DrissionPage**: 85% success rate (1,247 attempts)
  - Best performing on: product pages, category listings
  - Common failures: timeout on heavy JS pages
  - Optimal delay: 1.3 seconds

- **Selenium**: 75% success rate (892 attempts)  
  - Best performing on: dynamic content, AJAX-heavy pages
  - Common failures: stale element references
  - Optimal delay: 1.8 seconds

## Site Learning Insights
### Recently Discovered Patterns
- Category "smartphones" shows 95% selector stability
- Peak hours (9-17 UTC) have 23% slower response times
- Image lazy loading requires 2s wait for data-src population

### Failed URL Patterns
- `/product/.*-out-of-stock` → 90% stock status extraction failures
- `/category/.*\?page=[5-9]` → Pagination beyond page 4 unreliable

Adding New Learning Insights

Manual Memory Updates:

# Example: Adding new learning from analysis
from utils.primitive_loader import PrimitiveManager

manager = PrimitiveManager()
memory = manager.load_memory()

# Add new insight
new_insight = {
    "pattern": "Product pages with video content",
    "discovery": "Require 3.5s additional wait time",
    "success_rate_improvement": "12%",
    "discovered_at": "2025-10-15"
}

manager.update_memory("site_learnings", new_insight)

Automated Memory Updates (via workflow):

# The workflow automatically updates memory based on execution results
# See scraping-workflow.prompt.md Phase 6: Learning & Memory Updates

Workflow Customization Guide

The scraping-workflow.prompt.md defines the 6-phase agentic workflow. Here's how to customize it:

Adding a New Phase

# Add after Phase 6 in scraping-workflow.prompt.md:

## Phase 7: Competitive Analysis
**Objective**: Compare extracted data with competitor insights

**Validation Gate**: Competitive data availability > 60%

**Process**:
1. **Price Comparison**
   - Cross-reference with competitor databases
   - Calculate market positioning metrics
   - Identify pricing opportunities

2. **Feature Analysis** 
   - Compare product specifications
   - Analyze feature completeness
   - Generate competitive intelligence

**Success Criteria**:
- Market positioning calculated: ✓
- Competitive gaps identified: ✓
- Recommendations generated: ✓

**Failure Actions**:
- Log competitive data gaps
- Flag for manual review
- Continue with standard workflow

Modifying Validation Gates

# Customize quality thresholds in workflow phases:

## Phase 5: Quality Evaluation & Scoring (Modified)
**Quality Dimensions**:
- **Data Completeness**: Required fields present (threshold: 90% → 95%)
- **Format Validation**: Proper types and formats (threshold: 95% → 98%)  
- **Content Quality**: Meaningful, non-empty values (threshold: 85% → 90%)

**Custom Validation Rules**:
- Price must be valid MDL format: \d{1,6}(,\d{3})* MDL
- Product titles must be 10-200 characters
- Categories must match predefined taxonomy
- Images must have valid URLs and dimensions > 200px

Example: Adding a New Scraping Method

Here's how to add a new scraping method to the agentic framework:

1. Create the Method Implementation

# In src/darwin_scraper_complete.py, add new method:

async def extract_with_playwright(self, url: str) -> Dict[str, Any]:
    """
    New Playwright-based extraction method for advanced scenarios.
    
    Returns:
        Dict containing extracted product data
    """
    from playwright.async_api import async_playwright
    
    async with async_playwright() as p:
        browser = await p.chromium.launch(headless=True)
        page = await browser.new_page()
        
        try:
            # Navigate with advanced options
            await page.goto(url, wait_until='networkidle', timeout=30000)
            
            # Advanced extraction logic
            product_data = await self._extract_with_playwright_selectors(page)
            
            # Update memory with performance data
            self._update_method_performance('playwright', True, 
                                          response_time=page.evaluate('performance.now()'))
                                          
            return product_data
            
        except Exception as e:
            self._update_method_performance('playwright', False, error=str(e))
            raise
        finally:
            await browser.close()

2. Update Agent Memory Template

# Add to .memory.md:

## Method Performance Tracking
- **Playwright**: 0% success rate (0 attempts) [NEW METHOD]
  - Best performing on: [To be determined]
  - Common failures: [To be analyzed]
  - Optimal delay: [To be calibrated]
  - Advanced features: Network interception, mobile emulation

3. Update Executor Chat Mode

# Add to executor.chatmode.md:

## Available Extraction Methods
4. **Playwright Method** (NEW)
   - **Use Cases**: Advanced browser automation, mobile emulation
   - **Strengths**: Network interception, advanced waiting strategies
   - **Performance**: TBD (currently in testing)
   - **Best For**: SPAs with complex state management

## Method Selection Logic (Updated)
```python
def select_optimal_method(self, url: str, context: Dict) -> str:
    """Enhanced method selection with Playwright support"""
    
    # Check for advanced scenarios requiring Playwright
    if self._requires_advanced_automation(url, context):
        return 'playwright'
    
    # Existing logic...
    performance_data = self.memory_manager.get_method_performance()
    
    if 'mobile' in context.get('user_agent', '').lower():
        return 'playwright'  # Best mobile emulation
        
    # Continue with existing selection logic...

4. Add Method to Workflow

# Update scraping-workflow.prompt.md Phase 4:

## Phase 4: Execution & Data Extraction (Enhanced)
**Available Methods**:
1. DrissionPage (85% success rate)
2. Selenium (75% success rate)  
3. BeautifulSoup (65% success rate)
4. Playwright (TBD% success rate) [NEW]
5. Auto (80% success rate) - includes Playwright in fallback chain

**Method Selection Criteria** (Updated):
- Complex SPAs or mobile emulation needed → Playwright
- Dynamic content with AJAX → DrissionPage or Playwright  
- Heavy JavaScript interactions → Selenium or Playwright
- Static content optimization → BeautifulSoup
- Uncertain scenarios → Auto (tries all methods including Playwright)

5. Update Tests

# Add to tests/test_primitives.py:

def test_new_playwright_method_integration(self):
    """Test that Playwright method is properly integrated"""
    memory = self.manager.load_memory()
    memory_content = memory.content
    
    # Check method is documented in memory
    assert 'Playwright' in memory_content
    assert 'success rate' in memory_content
    
    # Verify method availability in executor chat mode
    executor = self.manager.load_chatmode('executor')
    assert 'Playwright Method' in executor.content
    assert 'Advanced browser automation' in executor.content
