Agent System Overview

What are Claude Code Agents?​

Agents are specialized AI assistants within Claude Code, each optimized for specific development tasks. Just like a development team has frontend experts, backend experts, and testing experts, Claude Code's agent system allows you to call upon the most suitable professional assistant for your current task.

Why do we need specialized agents?​

Custom Agent Development​

Creating Professional Agents​

You can create custom agents for specific needs:

{
  "agents": {
    "frontend-expert": {
      "name": "Frontend Expert",
      "description": "Expert agent focused on modern frontend development",
      "specialties": [
        "React/Vue.js development",
        "Responsive design",
        "Frontend performance optimization",
        "User experience design"
      ],
      "tools": ["webpack", "vite", "sass", "jest"],
      "personality": {
        "style": "Detailed and practical",
        "focus": "User experience and performance",
        "communication": "Clear step-by-step instructions"
      }
    }
  }
}

Agent Configuration Parameters​

{
  "agentConfig": {
    "model": "claude-3-5-sonnet-20241022",
    "temperature": 0.1,
    "maxTokens": 4096,
    "systemPrompt": "You are a professional frontend development expert...",
    "tools": ["browser", "bundler", "testing"],
    "knowledgeBase": ["react-docs", "web-vitals", "a11y-guidelines"]
  }
}

Agent Collaboration Modes​

1. Pipeline Mode​

Agents collaborate in sequence to complete tasks:

> Develop a complete user management feature

Execution flow:
@architect → Design system architecture
@developer → Implement core functionality
@tester → Write test cases
@code-reviewer → Code quality review
@docs → Generate technical documentation
@devops → Deployment configuration

2. Parallel Collaboration Mode​

Multiple agents work simultaneously:

> Optimize overall application performance

Parallel execution:
@performance-expert → Frontend performance optimization
@database-expert → Database query optimization
@infrastructure-expert → Server configuration optimization
@code-reviewer → Code performance review

3. Expert Consultation Mode​

Consult relevant experts when encountering specific issues:

Encounter security issue during development:
> @security-expert Does this JWT implementation have security risks?

Encounter performance issue:
> @performance-expert Why is the page loading so slowly?

Need architectural advice:
> @architect Is this microservice decomposition reasonable?

Agent Management Best Practices​

1. Reasonable Agent Selection​

# ✅ Correct: Targeted selection
> @security-expert Review the security of this login system
> @performance-expert Optimize the performance of this query

# ❌ Wrong: Overuse
> @security-expert Help me write a Hello World program

2. Provide Sufficient Context​

# ✅ Sufficient context
> @code-reviewer Review this payment module code, focus on security and error handling

# ❌ Lack of context
> @code-reviewer Look at this code

3. Clear Expected Results​

# ✅ Clear expectations
> @tester Write tests for user registration functionality, including normal flow, boundary cases, and error handling

# ❌ Vague requirements
> @tester Write some tests
