# Agent-Skill-Creator Internal Flow: What Happens "Under the Hood"

## 🎯 **Example Scenario**

**User Command:**
```
"I'd like to automate what is being explained and described in this article [financial data analysis article content]"
```

## 🚀 **Complete Detailed Flow**

### **PHASE 0: Detection and Automatic Activation**

#### **0.1 User Intent Analysis**
Claude Code analyzes the command and detects activation patterns:

```
DETECTED PATTERNS:
✅ "automate" → Workflow automation activation
✅ "what is being explained" → External content processing
✅ "in this article" → Transcribed/intent processing
✅ Complete command → Activates Agent-Skill-Creator
```

#### **0.2 Meta-Skill Loading**
```python
# Claude Code internal system
if matches_pattern(user_input, SKILL_ACTIVATION_PATTERNS):
    load_skill("agent-creator-en-v2")
    activate_5_phase_process(user_input)
```

**What happens:**
- The agent-creator's `SKILL.md` is loaded into memory
- The skill context is prepared
- The 5 phases are initialized

---

### **PHASE 1: DISCOVERY - Research and Analysis**

#### **1.1 Article Content Processing**
```python
# Internal processing simulation
def analyze_article_content(article_text):
    # Structured information extraction
    workflows = extract_workflows(article_text)
    tools_mentioned = identify_tools(article_text)
    data_sources = find_data_sources(article_text)
    complexity_assessment = estimate_complexity(article_text)

    return {
        'workflows': workflows,
        'tools': tools_mentioned,
        'data_sources': data_sources,
        'complexity': complexity_assessment
    }
```

**Practical Example - Financial Analysis Article:**
```
ANALYZED ARTICLE CONTENT:
├─ Identified Workflows:
│  ├─ "Download stock market data"
│  ├─ "Calculate technical indicators"
│  ├─ "Generate analysis charts"
│  └─ "Create weekly report"
├─ Mentioned Tools:
│  ├─ "pandas library"
│  ├─ "Alpha Vantage API"
│  ├─ "Matplotlib for charts"
│  └─ "Excel for reports"
└─ Data Sources:
   ├─ "Yahoo Finance API"
   ├─ "Local CSV files"
   └─ "SQL database"
```

#### **1.2 API and Tools Research**
```bash
# Automatic WebSearch performed by Claude
WebSearch: "Best Python libraries for financial data analysis 2025"
WebSearch: "Alpha Vantage API documentation Python integration"
WebSearch: "Financial reporting automation tools Python"
```

#### **1.3 AgentDB Enhancement (if available)**
```python
# Transparent AgentDB integration
agentdb_insights = query_agentdb_for_patterns("financial_analysis")
if agentdb_insights.success_rate > 0.8:
    apply_learned_patterns(agentdb_insights.patterns)
```

#### **1.4 Technology Stack Decision**
```
TECHNICAL DECISION:
✅ Python as primary language
✅ pandas for data manipulation
✅ Alpha Vantage for market data
✅ Matplotlib/Seaborn for visualizations
✅ ReportLab for PDF generation
```

---

### **PHASE 2: DESIGN - Functionality Specification**

#### **2.1 Use Case Analysis**
```python
def define_use_cases(workflows_identified):
    use_cases = []
    for workflow in workflows_identified:
        use_case = {
            'name': workflow['title'],
            'description': workflow['description'],
            'inputs': workflow['required_inputs'],
            'outputs': workflow['expected_outputs'],
            'frequency': workflow['frequency'],
            'complexity': workflow['complexity_level']
        }
        use_cases.append(use_case)
    return use_cases
```

**Defined Use Cases:**
```
USE CASE 1: Data Acquisition
- Description: Download historical stock data
- Input: List of tickers, period
- Output: DataFrame with OHLCV data
- Frequency: Daily

USE CASE 2: Technical Analysis
- Description: Calculate technical indicators
- Input: Price DataFrame
- Output: DataFrame with indicators
- Frequency: On demand

USE CASE 3: Report Generation
- Description: Create PDF report
- Input: Analysis results
- Output: Formatted report
- Frequency: Weekly
```

#### **2.2 Methodology Definition**
```python
def specify_methodologies(use_cases):
    methodologies = {
        'data_validation': 'Data quality validation',
        'error_handling': 'Robust error handling',
        'caching_strategy': 'Data caching for performance',
        'logging': 'Detailed logging for debugging',
        'configuration': 'Flexible configuration via JSON'
    }
    return methodologies
```

---

### **PHASE 3: ARCHITECTURE - Structural Decision**

#### **3.1 Complexity Analysis (DECISION_LOGIC.md applied)**
```python
# Automatic evaluation based on article content
complexity_score = calculate_complexity({
    'number_of_workflows': 4,           # Data + Analysis + Reports + Alerts
    'workflow_complexity': 'medium',    # API calls + calculations + formatting
    'data_sources': 3,                  # Yahoo Finance + CSV + Database
    'estimated_code_lines': 2500,       # Above Simple Skill threshold
    'domain_expertise': ['finance', 'data_science', 'reporting']
})

# Architecture decision
if complexity_score > SIMPLE_SKILL_THRESHOLD:
    architecture = "complex_skill_suite"
else:
    architecture = "simple_skill"
```

**In this example:**
```
ANALYSIS RESULT:
✅ Multiple distinct workflows (4)
✅ Medium-high complexity
✅ Multiple data sources
✅ Estimate > 2000 lines of code
✅ Multiple domains of expertise

DECISION: Complex Skill Suite
GENERATED NAME: financial-analysis-suite-cskill
```

#### **3.2 Component Structure Definition**
```python
def design_component_skills(complexity_analysis):
    if complexity_analysis.architecture == "complex_skill_suite":
        components = {
            'data-acquisition': 'Handle data sourcing and validation',
            'technical-analysis': 'Calculate indicators and signals',
            'visualization': 'Create charts and graphs',
            'reporting': 'Generate professional reports'
        }
    return components
```

#### **3.3 Performance and Cache Planning**
```python
performance_plan = {
    'data_cache': 'Cache market data for 1 day',
    'calculation_cache': 'Cache expensive calculations',
    'parallel_processing': 'Process multiple stocks concurrently',
    'batch_operations': 'Batch API calls when possible'
}
```

---

### **PHASE 4: DETECTION - Keywords and Activation**

#### **4.1 Keyword Analysis**
```python
def determine_activation_keywords(workflows, tools):
    keywords = {
        'primary': [
            'financial analysis',
            'market data',
            'technical indicators',
            'investment reports'
        ],
        'secondary': [
            'automate analysis',
            'generate charts',
            'calculate returns',
            'data extraction'
        ],
        'domains': [
            'finance',
            'investments',
            'quantitative analysis',
            'stock market'
        ]
    }
    return keywords
```

#### **4.2 Precise Description Creation**
```python
def create_skill_descriptions(components):
    descriptions = {}
    for component_name, component_function in components.items():
        description = f"""
        Component skill for {component_function} in financial analysis.

        When to use: When user mentions {determine_activation_keywords(component_name)}

        Capabilities: {list_component_capabilities(component_name)}
        """
        descriptions[component_name] = description
    return descriptions
```
