Implement

/implement - Feature Implementation

Purpose

Implement features, components, and code functionality with intelligent expert activation, comprehensive development support, and best practices enforcement.

Usage

/implement [feature-description] [--type <type>] [--framework <name>] [--<flags>]

Arguments

• [feature-description] - Clear description of what to implement
• --type component|api|service|feature|module - Implementation type
• --framework react|vue|angular|express|fastapi|etc - Target framework
• --safe - Use conservative implementation approach
• --iterative - Enable iterative development with validation
• --with-tests - Include test implementation
• --documentation - Generate documentation alongside code
• --agent <agent-name> - Manually activate specific agent
• --agents <agent-list> - Activate multiple coordinated agents

Auto-Activation Patterns

Personas (Context-Dependent)

• Frontend: UI components, React/Vue/Angular development

  • Keywords: component, UI, React, Vue, responsive, accessibility
  • Files: *.jsx, *.tsx, *.vue, *.css

• Backend: APIs, services, database integration

  • Keywords: API, database, server, endpoint, authentication
  • Files: *.js, *.ts, *.py, *.go, controllers/*, models/*

• Security: Authentication, authorization, data protection

  • Keywords: auth, security, encryption, validation
  • Auto-activates for sensitive operations

• Architect: System design and module structure

  • Complex features requiring architectural decisions
  • Multi-component implementations

MCP Servers

• Banana: Primary for UI component generation and design systems
• Context7: Framework documentation and implementation patterns
• Sequential: Complex business logic and multi-step workflows

Agent Coordination

• Single Domain: Domain-specific agent (frontend, backend, etc.)
• Multi-Domain: Hierarchical coordination with multiple specialists
• Testing: Automatic test-agent activation with --with-tests
• Documentation: Automatic docs-agent activation with --documentation

Execution Workflow

1. Requirements Analysis

   • Parse feature description and detect technology context
   • Identify required components and dependencies
   • Determine implementation complexity

2. Persona & Agent Activation

   • Auto-activate relevant personas based on context
   • Route to specialized agents when beneficial
   • Coordinate MCP servers for enhanced capabilities

3. Implementation Phase

   • Generate code with framework best practices
   • Apply security and quality validation
   • Follow project conventions and patterns
   • Use appropriate design patterns

4. Testing & Validation

   • Generate tests if requested
   • Validate against requirements
   • Check for common pitfalls and vulnerabilities

5. Documentation & Next Steps

   • Document implementation decisions
   • Provide usage examples
   • Suggest testing and integration steps

Examples

# Frontend component with tests
/implement LoginComponent --type component --framework react --with-tests

# Backend API with documentation
/implement user-authentication-system --type feature --documentation

# Multi-agent full-stack feature
/implement user-dashboard --agents frontend,backend,test,docs

# Safe iterative implementation
/implement payment-processing-service --type service --safe --iterative

# Explicit agent selection
/implement REST-API-users --type api --agent gd-backend-agent
