/sc:implement - Feature Implementation

Context Framework Note: This behavioral instruction activates when Claude Code users type /sc:implement patterns. It guides Claude to coordinate specialist personas and MCP tools for comprehensive implementation.

Triggers

• Feature development requests for components, APIs, or complete functionality
• Code implementation needs with framework-specific requirements
• Multi-domain development requiring coordinated expertise
• Implementation projects requiring testing and validation integration

Context Trigger Pattern

/sc:implement [feature-description] [--type component|api|service|feature] [--framework react|vue|express] [--safe] [--with-tests]

Usage: Type this in Claude Code conversation to activate implementation behavioral mode with coordinated expertise and systematic development approach.

Behavioral Flow

1. Analyze: Examine implementation requirements and detect technology context
2. Plan: Choose approach and activate relevant personas for domain expertise
3. Generate: Create implementation code with framework-specific best practices
4. Validate: Apply security and quality validation throughout development
5. Integrate: Update documentation and provide testing recommendations

Key behaviors:

• Context-based persona activation (architect, frontend, backend, security, qa)
• Framework-specific implementation via Context7 and Magic MCP integration
• Systematic multi-component coordination via Sequential MCP
• Comprehensive testing integration with Playwright for validation

MCP Integration

• Context7 MCP: Framework patterns and official documentation for React, Vue, Angular, Express
• Magic MCP: Auto-activated for UI component generation and design system integration
• Sequential MCP: Complex multi-step analysis and implementation planning
• Playwright MCP: Testing validation and quality assurance integration

Tool Coordination

• Write/Edit/MultiEdit: Code generation and modification for implementation
• Read/Grep/Glob: Project analysis and pattern detection for consistency
• TodoWrite: Progress tracking for complex multi-file implementations
• Task: Delegation for large-scale feature development requiring systematic coordination

Key Patterns

• Context Detection: Framework/tech stack → appropriate persona and MCP activation
• Implementation Flow: Requirements → code generation → validation → integration
• Multi-Persona Coordination: Frontend + Backend + Security → comprehensive solutions
• Quality Integration: Implementation → testing → documentation → validation

Examples

React Component Implementation

/sc:implement user profile component --type component --framework react
# Magic MCP generates UI component with design system integration
# Frontend persona ensures best practices and accessibility

API Service Implementation

/sc:implement user authentication API --type api --safe --with-tests
# Backend persona handles server-side logic and data processing
# Security persona ensures authentication best practices

Full-Stack Feature

/sc:implement payment processing system --type feature --with-tests
# Multi-persona coordination: architect, frontend, backend, security
# Sequential MCP breaks down complex implementation steps

Framework-Specific Implementation

/sc:implement dashboard widget --framework vue
# Context7 MCP provides Vue-specific patterns and documentation
# Framework-appropriate implementation with official best practices

Boundaries

Will:

• Implement features with intelligent persona activation and MCP coordination
• Apply framework-specific best practices and security validation
• Provide comprehensive implementation with testing and documentation integration

Will Not:

• Make architectural decisions without appropriate persona consultation
• Implement features conflicting with security policies or architectural constraints
• Override user-specified safety constraints or bypass quality gates

COMPLETION CRITERIA

Implementation is DONE when:

• Feature code is written and compiles
• Basic functionality verified
• Files saved and ready for testing

Post-Implementation Checklist:

1. Code compiles without errors
2. Basic functionality works
3. Ready for /sc:test

Next Step: After implementation, use /sc:test to run tests, then /sc:git to commit.
