# Agent Creator - Enhanced with 4-Phase SOP Methodology

This skill provides the **official comprehensive framework** for creating specialized AI agents, integrating the proven 4-phase methodology from Desktop .claude-flow with Claude Agent SDK implementation and evidence-based prompting techniques.

## When to Use This Skill

Use agent-creator for:
- Creating project-specialized agents with deeply embedded domain knowledge
- Building agents for recurring tasks requiring consistent behavior
- Rewriting existing agents to optimize performance
- Creating multi-agent workflows with sequential or parallel coordination
- Agents that will integrate with MCP servers and Claude Flow

## The 4-Phase Agent Creation Methodology

**Source**: Desktop `.claude-flow/` official SOP documentation
**Total Time**: 2.5-4 hours per agent (first-time), 1.5-2 hours (speed-run)

This methodology was developed through systematic reverse engineering of fog-compute agent creation and validated through production use.

### Phase 1: Initial Analysis & Intent Decoding (30-60 minutes)

**Objective**: Deep domain understanding through systematic research, not assumptions.

**Activities**:
1. **Domain Breakdown**
   - What problem does this agent solve?
   - What are the key challenges in this domain?
   - What patterns do human experts use?
   - What are common failure modes?

2. **Technology Stack Mapping**
   - What tools, frameworks, libraries are used?
   - What file types, formats, protocols?
   - What integrations or APIs?
   - What configuration patterns?

3. **Integration Points**
   - What MCP servers will this agent use?
   - What other agents will it coordinate with?
   - What data flows in/out?
   - What memory patterns needed?

**Validation Gate**:

   - Self-consistency: When to use, how to apply
   - Program-of-thought: Decomposition patterns
   - Plan-and-solve: Planning frameworks

   Integrate these naturally into the agent's methodology.

3. **Quality Standards & Guardrails**

   - What validations to always run
   - When to escalate vs. retry
   - Error handling protocols

**Validation Gate**:

### Phase 4: Deep Technical Enhancement (60-90 minutes)

**Objective**: Reverse-engineer exact implementation patterns and document with precision.

**Activities**:
1. **Code Pattern Extraction**

   For technical agents, extract EXACT patterns from codebase:
   ```markdown
   ## Code Patterns I Recognize

   ### Pattern: [Name]
   **File**: `path/to/file.py:123-156`

   ```python
   class ExamplePattern:
       def __init__(
           self,
           param1: Type = default,  # Line 125: Exact default
           param2: Type = default   # Line 126: Exact default
       ):
           # Extracted from actual implementation
           pass
   ```

   **When I see this pattern, I know**:
   - [Specific insight about architecture]
   - [Specific constraint or requirement]
   - [Common mistake to avoid]
   ```

2. **Critical Failure Mode Documentation**

   From experience and domain knowledge:
   ```markdown
   ## Critical Failure Modes

   ### Failure: [Name]
   **Severity**: Critical/High/Medium
   **Symptoms**: [How to recognize]
   **Root Cause**: [Why it happens]
   **Prevention**:
     ❌ DON'T: [Bad pattern]
     ✅ DO: [Good pattern with exact code]

   **Detection**:
     ```bash
     # Exact command to detect this failure
     [command]
     ```
   ```

3. **Integration Patterns**

   Document exact MCP tool usage:
   ```markdown
   ## MCP Integration Patterns

   ### Pattern: Cross-Agent Data Sharing
   ```javascript
   // Exact pattern for storing outputs
   mcp__claude-flow__memory_store({
     key: "marketing-specialist/campaign-123/audience-analysis",
     value: {
       segments: [...],
       targeting: {...},
       confidence: 0.89
     },
     ttl: 86400
   })
   ```

   **Namespace Convention**:
   - Format: `{agent-role}/{task-id}/{data-type}`
   - Example: `backend-dev/api-v2/schema-design`
   ```

4. **Performance Metrics**

   Define what to track:
   ```markdown
   ## Performance Metrics I Track

   ```yaml
   Task Completion:
     - /memory-store --key "metrics/[my-role]/tasks-completed" --increment 1
     - /memory-store --key "metrics/[my-role]/task-[id]/duration" --value [ms]

   Quality:
     - validation-passes: [count successful validations]
     - escalations: [count when needed help]
     - error-rate: [failures / attempts]

   Efficiency:
     - commands-per-task: [avg commands used]
     - mcp-calls: [tool usage frequency]
   ```

   These metrics enable continuous improvement.
   ```

**Validation Gate**:
- [ ] Code patterns include file/line references
- [ ] Failure modes have detection + prevention
- [ ] MCP patterns show exact syntax
- [ ] Performance metrics defined
- [ ] Agent can self-improve through metrics

**Outputs**:
- Enhanced system prompt (v2.0)
- Code pattern library
- Failure mode handbook
- Integration pattern guide

## Claude Agent SDK Implementation

Once system prompt is finalized, implement with SDK:

### TypeScript Implementation

```typescript
import { query, tool } from '@anthropic-ai/claude-agent-sdk';
import { z } from 'zod';

// Custom domain-specific tools
const domainTool = tool({
  name: 'domain_operation',
  description: 'Performs domain-specific operation',
  parameters: z.object({
    param: z.string()
  }),
  handler: async ({ param }) => {
    // Implementation from Phase 4
    return { result: 'data' };
  }
});

// Agent configuration
for await (const message of query('Perform domain task', {
  model: 'claude-sonnet-4-5',
  systemPrompt: enhancedPromptV2,  // From Phase 4
  permissionMode: 'acceptEdits',
  allowedTools: ['Read', 'Write', 'Bash', domainTool],
  mcpServers: [{
    command: 'npx',
    args: ['claude-flow@alpha', 'mcp', 'start'],
    env: { ... }
  }],
  settingSources: ['user', 'project']
})) {
  console.log(message);
}
```

### Python Implementation

```python
from claude_agent_sdk import query, tool, ClaudeAgentOptions
import asyncio

@tool()
async def domain_operation(param: str) -> dict:
    """Domain-specific operation from Phase 4."""
    # Implementation
    return {"result": "data"}

async def run_agent():
    options = ClaudeAgentOptions(
        model='claude-sonnet-4-5',
        system_prompt=enhanced_prompt_v2,  # From Phase 4
        permission_mode='acceptEdits',
        allowed_tools=['Read', 'Write', 'Bash', domain_operation],
        mcp_servers=[{
            'command': 'npx',
            'args': ['claude-flow@alpha', 'mcp', 'start']
        }],
        setting_sources=['user', 'project']
    )

    async for message in query('Perform domain task', **options):
        print(message)

asyncio.run(run_agent())
```

## Quick Reference

### When to Use Each Phase

**Phase 1 (Analysis)**:
- Always - Required foundation
- Especially for domains you're less familiar with

**Phase 2 (Expertise Extraction)**:
- Always - Captures cognitive patterns
- Essential for complex reasoning tasks

**Phase 3 (Architecture)**:
- Always - Creates base system prompt
- Critical for clear behavioral specification

**Phase 4 (Enhancement)**:
- For production agents
- For technical domains requiring exact patterns
- When precision and failure prevention are critical

### Speed-Run Approach (Experienced Creators)

1. **Combined Phase 1+2** (30 min): Rapid domain analysis + spec
2. **Phase 3** (30 min): Base prompt from template
3. **Phase 4** (45 min): Code patterns + failure modes
4. **Testing** (15 min): Quick validation suite

**Total**: 2 hours for experienced creators with templates

---

## Examples from Production

### Example: Marketing Specialist Agent

See: `docs/agent-architecture/agents-rewritten/MARKETING-SPECIALIST-AGENT.md`

**Phase 1 Output**: Marketing domain analysis, tools (Google Analytics, SEMrush, etc.)
**Phase 2 Output**: Marketing expertise (CAC, LTV, funnel optimization, attribution)
**Phase 3 Output**: Base prompt with 9 specialist commands
**Phase 4 Output**: Campaign workflow patterns, A/B test validation, ROI calculations

**Result**: Production-ready agent with deeply embedded marketing expertise

## Maintenance & Iteration

### Continuous Improvement

1. **Metrics Review**: Weekly review of agent performance metrics
2. **Failure Analysis**: Document and fix new failure modes
3. **Pattern Updates**: Add newly discovered code patterns
4. **Workflow Optimization**: Refine based on usage patterns

### Version Control
