Claude Code Autonomous Development Environment

A comprehensive autonomous development environment using Claude Code with specialized agents, slash commands, and containerized development workflows.

🚀 Quick Start

1. Clone and Setup

   git clone <this-repo>
   cd claude-agent-system
   code .  # VS Code will prompt to open in dev container

2. Start Claude Code

   claude-code

3. Initialize Your Project

   Use /prd when:

   • Starting a completely new project
   • Adding major new features to existing projects
   • Need to clarify or document complex requirements
   • Working with stakeholders who need structured requirements

   Skip /prd when:

   • Making simple bug fixes or small improvements
   • Project requirements are already clear and well-defined
   • Working on quick prototypes or experimental code

   /prd          # Interactive requirements gathering (when needed)
   /project-init # Configure project-specific settings (always run)
   

4. Start Building

   /plan-execution "Build a REST API for task management with authentication"
   

5. Claude Code Delivers

   • Automatically plans and executes using specialized agents
   • Implements with comprehensive testing and quality gates
   • Delivers production-ready, documented code

🏗️ Architecture

Multi-Agent System

Requirements → Architect → Developer → Debugger → Quality Reviewer → Technical Writer

Available Agents (in .claude/agents/):

• 🏗️ architect - Technical design and architecture analysis
• 👨‍💻 developer - Implementation with testing focus
• 🐛 debugger - Systematic error investigation and root cause analysis
• ✅ quality-reviewer - Code quality, security, and performance review
• 📝 technical-writer - Documentation and technical explanations

Slash Commands

Located in .claude/commands/:

• /prd - Interactive Product Requirements Document creation
• /project-init - Analyze codebase and configure project-specific settings
• /plan-execution - Systematic multi-phase project execution

Quality Gates

• ✅ Zero linting violations
• ✅ 100% test pass rate
• ✅ >80% test coverage for new code
• ✅ Performance within 5% of baseline
• ✅ Security review passed
• ✅ Comprehensive documentation

🛠️ Development Environment

DevContainer Features

• Isolated & Safe: Containerized development with firewall protection
• Permission Managed: Non-root user with appropriate restrictions
• Pre-configured: Claude Code CLI and development tools ready
• Network Controlled: Controlled network access for security

Configuration Management

• Project Memory: CLAUDE.md serves as project memory and configuration
• Agent Specialization: Each agent has tailored instructions and patterns
• Advanced Prompting: Techniques from prompt-engineering.md

🎯 Usage Modes

Autonomous Mode (Recommended)

/plan-execution "Implement user authentication with JWT tokens, password hashing, and rate limiting"

Claude Code automatically:

1. Analyzes requirements using architect agent
2. Implements using developer agent with testing
3. Debugs any issues systematically
4. Reviews code quality and security
5. Generates comprehensive documentation

Manual Agent Mode

# Use specific agents directly
claude-code --agent architect "Design a caching strategy for high-traffic API"
claude-code --agent developer "Implement Redis caching with connection pooling"
claude-code --agent quality-reviewer "Review caching implementation for security issues"

Command Mode

/prd          # Interactive requirements gathering
/project-init # Configure for your specific project

🔧 Project Initialization

When you run /project-init, the system:

1. Analyzes Your Codebase: Detects languages, frameworks, build tools, testing setup
2. Updates CLAUDE.md: Adds project-specific build commands, conventions, patterns
3. Configures Agents: Tailors each agent's instructions for your tech stack
4. Validates Environment: Ensures linting, testing, and build commands work
5. Applies Templates: Uses appropriate templates from .claude/templates/

Important: After initialization, delete this README to avoid confusion - /project-init will remind you.

🚨 Quality & Security

Error Handling Standards

• Never ignore errors - always handle appropriately
• Wrap errors with context for debugging
• Use appropriate error types for your stack
• Propagate errors with proper context

Testing Requirements

• Integration tests for system behavior
• Unit tests for pure logic functions
• Property-based testing where applicable
• Test with real services when possible
• Cover edge cases and failure scenarios

Security Boundaries

• Development container runs safely with dangerously-skip-permissions
• Firewall rules restrict network access appropriately
• Non-root user with development-only permissions
• No secrets or credentials committed to repository

📚 Advanced Features

Memory Management

• Project-specific configuration automatically loaded from CLAUDE.md
• Agent memory with specialized knowledge patterns
• Context preservation across development sessions

Workflow Automation

• Extended thinking for complex architectural decisions
• Resume/continue functionality with full context
• Integration with CI/CD and build systems

🎬 Example Workflows

Full-Stack Application:

/plan-execution "Build a React + Node.js todo app with real-time updates, PostgreSQL database, JWT auth, and comprehensive test suite"

API Development:

/plan-execution "Create a RESTful inventory API with OpenAPI docs, input validation, rate limiting, audit logging, and Docker deployment"

Data Pipeline:

/plan-execution "Implement CSV processing pipeline with validation, transformation, multiple output formats, and error handling"
