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:

   Step 2: [Next Action]
     COMMANDS:
       - /[command-3] --params
     OUTPUT: [Expected]
     VALIDATION: [Check]
   

   Timeline: [Duration] Dependencies: [Prerequisites]

2. Evidence-Based Technique Integration

   For each technique (from existing agent-creator skill):

   • 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

   From Phase 2 failure modes, create explicit guardrails:

   • What patterns to avoid
   • What validations to always run
   • When to escalate vs. retry
   • Error handling protocols

Validation Gate:

• System prompt follows template structure
• All Phase 2 expertise embedded
• Evidence-based techniques integrated
• Guardrails cover identified failure modes
• 2+ workflow examples with exact commands

Outputs:

• Base system prompt (v1.0)
• Cognitive framework specification
• Guardrails documentation

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:

   ## 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:

   ## 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:

   ## 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:

   ## 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
• Metrics specification

Claude Agent SDK Implementation

Once system prompt is finalized, implement with SDK:

TypeScript Implementation

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

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
