/write src/components/Button.tsx
# → Shows preview
# → Asks for confirmation
# → Explains what will be created

Planning Mode (📋)

Strategic planning with comprehensive execution plans:

# Switch to planning mode
/plan

# Create a project plan
/plan "Build a complete e-commerce platform"

# View todos
/todo

Auto Mode (🤖)

Autonomous execution with minimal intervention:

# Switch to auto mode
/auto

# Execute tasks autonomously
/auto "Create a React component with tests and documentation"

🛠️ Practical Examples

Example 1: Create a React Component

1. Start NikCLI

   nikcli
   

2. Create Component

   /agent universal-agent "Create a reusable Button component with TypeScript, styled-components, and Jest tests"
   

3. Review Results

   # Check what was created
   /ls src/components/
   
   # Read the component
   /read src/components/Button.tsx
   
   # Check tests
   /read src/components/Button.test.tsx
   

4. Run Tests

   /run npm test Button.test.tsx
   

Example 2: Analyze Existing Code

1. Analyze Project

   /agent universal-agent "Analyze this React project for code quality, performance issues, and security vulnerabilities"
   

2. Review Analysis

   # The agent will provide detailed analysis including:
   # - Code quality metrics
   # - Performance bottlenecks
   # - Security vulnerabilities
   # - Improvement recommendations
   

3. Apply Fixes

   /agent universal-agent "Fix the issues identified in the analysis and optimize the code"
   

Example 3: Full-Stack Development

1. Plan the Project

   /plan "Create a task management app with React frontend, Node.js API, and PostgreSQL database"
   

2. Execute Backend

   /agent universal-agent "Create the backend API with Express, PostgreSQL, and authentication"
   

3. Build Frontend

   /agent universal-agent "Create the React frontend with task management features"
   

4. Integrate & Test

   /agent universal-agent "Connect frontend to backend and add comprehensive testing"

🎯 Best Practices

1. Start Simple

Begin with basic file operations and gradually move to complex agent tasks:

# Start with simple commands
/read package.json
/ls src/

# Move to agent tasks
/agent universal-agent "Create a simple component"

2. Use Planning Mode for Complex Projects

For large projects, use planning mode to break down tasks:

/plan "Build a complete application"
# → Creates detailed execution plan
# → Generates todo.md
# → Sets up approval workflow

3. Leverage Agent Capabilities

Understand what each agent can do:

# Check agent capabilities
/agents

# Use specific capabilities
/agent universal-agent "Optimize this code for performance"
/agent universal-agent "Add comprehensive testing to this project"

4. Monitor and Learn

Use monitoring tools to understand performance:

# Check metrics
/stats

# View agent performance
/agent universal-agent --metrics

# Learn from patterns
/agent universal-agent --learn
