Core Components

1. Agent System

The system utilizes specialized AI agents for different tasks:

Available Agents

Agent Purpose Tools Status
5w2h-analyzer Systematic problem analysis using 5W2H methodology Read, Write, Edit, Glob, Grep ✅ Active
agent-builder Meta-agent for creating new specialized agents Read, Write, Edit, Glob, Grep, Bash ✅ Active
code-reviewer Expert code review and quality assurance Read, Grep, Glob, Bash ✅ Active
python-developer Python development and optimization specialist Read, Write, Edit, Glob, Grep, Bash ✅ Active
documentation-manager Technical and scientific documentation specialist Read, Write, Edit, Glob, Grep, Bash ✅ Active
database-optimizer Database performance optimization specialist Read, Write, Edit, Glob, Grep, Bash ✅ Active

Agent Configuration

Agents are defined as Markdown files with YAML frontmatter:

---
name: agent-name
description: Agent purpose and capabilities
tools: Read, Write, Edit, Glob, Grep, Bash
version: 1.0.0
category: classification
author: Claude Code Agent Builder
created: 2025-08-31
status: active
---

Agent Storage

2. Hook System

The hook system enables automated workflows and data capture:

Configuration

{
  "hooks": {
    "UserPromptSubmit": [
      {
        "matcher": "",
        "hooks": [
          {
            "type": "command",
            "command": "jq -r '.prompt' >> /Users/taipm/GitHub/claude-code/prompts.txt"
          }
        ]
      }
    ]
  }
}

Hook Types

3. Analytics System

Comprehensive metrics tracking and performance monitoring:

Metrics Storage

logs/analytics/
└── real-time-metrics.json

Tracked Metrics

4. Permission System

Fine-grained access control for tools and agents:

Configuration Files

Permission Types

{
  "permissions": {
    "allow": [
      "Task(*)",
      "Task(agent-builder:*)",
      "Read(/Users/taipm/GitHub/claude-code/**)",
      "Bash(cat:*)"
    ],
    "deny": [],
    "ask": []
  }
}

Agent Interaction Patterns

Sequential Processing

User Request → Agent A → Agent B → Agent C → Final Output

Example: Code generation → Code review → Documentation

Parallel Processing

User Request → [Agent A, Agent B, Agent C] → Aggregated Output

Example: Multi-perspective analysis

Hierarchical Processing

Agent Development Workflow

  1. Requirements Analysis 
    Task(5w2h-analyzer:*) # Analyze requirements systematically
  2. Agent Creation 
    Task(agent-builder:*) # Create specialized agent
  3. Code Review 
    Task(code-reviewer:*) # Validate agent implementation
  4. Documentation 
    Task(documentation-manager:*) # Generate comprehensive docs
  5. Testing & Validation 
    Task(python-developer:*) # Test agent functionality

Performance Considerations

Agent Selection Optimization

Resource Management

Monitoring & Alerting

Security Model

Access Control

Audit Trail

Integration Guidelines

Adding New Agents

  1. Create agent file in .claude/agents/
  2. Add permissions to settings.local.json
  3. Test agent functionality
  4. Update documentation

Tool Integration

External System Integration

Troubleshooting

Common Issues

Agent Not Found

Error: Agent type 'agent-name' not found

Solution: Verify agent file exists and permissions are configured

Permission Denied

Error: Tool access denied

Solution: Add appropriate permissions to settings.local.json

Configuration Errors

# Invalid YAML frontmatter
---
name: agent-name
description: Missing quotes cause "parsing error
---

Solution: Validate YAML syntax and required fields

Debugging Process

  1. Verify File Structure: Check agent file exists and location
  2. Validate Configuration: Test YAML frontmatter parsing
  3. Check Permissions: Ensure tool access is granted
  4. Review Logs: Examine analytics and error logs
  5. Test Incrementally: Start with basic functionality
