Feature Implementation Router

Comprehensive feature implementation across the full stack with phased, incremental development approach. Routes feature implementation requests to specialized operations for different layers or full-stack implementation.

Operations

• implement - Complete full-stack feature implementation across all layers (database, backend, frontend, integration)
• database - Database layer only (migrations, models, schemas, indexes)
• backend - Backend layer only (services, API endpoints, validation, tests)
• frontend - Frontend layer only (components, state, API integration, tests)
• integrate - Integration and polish phase (E2E tests, performance, security, documentation)
• scaffold - Scaffold feature structure and boilerplate across all layers

Usage Examples

# Complete full-stack feature
/feature implement description:"user authentication with OAuth and 2FA" tests:"comprehensive"

# Database layer only
/feature database description:"user profiles table with indexes" migration:"add_user_profiles"

# Backend API only
/feature backend description:"REST API for product search with filters" validation:"strict"

# Frontend components only
/feature frontend description:"product catalog with infinite scroll and filters" framework:"react"

# Integration and polish
/feature integrate feature:"authentication flow" scope:"E2E tests and performance"

# Scaffold feature structure
/feature scaffold name:"notification-system" layers:"database,backend,frontend"

Router Logic

Parse the first word of $ARGUMENTS to determine operation:

1. Extract operation from first word of $ARGUMENTS

2. Extract remaining arguments as operation parameters

3. Route to instruction file:

   • "implement" → Read .claude/commands/fullstack/feature/implement.md and execute
   • "database" → Read .claude/commands/fullstack/feature/database.md and execute
   • "backend" → Read .claude/commands/fullstack/feature/backend.md and execute
   • "frontend" → Read .claude/commands/fullstack/feature/frontend.md and execute
   • "integrate" → Read .claude/commands/fullstack/feature/integrate.md and execute
   • "scaffold" → Read .claude/commands/fullstack/feature/scaffold.md and execute

4. Pass extracted parameters to the instruction file

5. Return structured implementation

Error Handling:

• If operation is unrecognized, list available operations with examples
• If parameters are missing, request clarification with expected format
• If requirements are unclear, ask specific questions about scope and acceptance criteria
• Provide clear error messages with usage examples

Security:

• Validate all input parameters
• Ensure no hardcoded secrets in generated code
• Follow security best practices for each layer
• Include validation and sanitization in generated code
