CRUD with Spec-Kit

CRUD with Spec-Kit Skill

When to Use This Skill

Use this conceptual skill when you need to implement CRUD (Create, Read, Update, Delete) operations for applications using Spec-Kit and Claude Code. This skill is appropriate for:

• Building data-driven applications with well-defined specifications
• Generating backend APIs from feature specifications
• Creating frontend clients that consume CRUD APIs
• Ensuring implementation aligns with specified success criteria
• Rapidly scaffolding CRUD functionality based on specifications
• Maintaining consistency between specification and implementation

This skill should NOT be used for:

• Applications without clear specifications
• Systems requiring complex business logic beyond basic CRUD
• Prototypes where specifications are still evolving rapidly
• Applications with non-standard data access patterns

Prerequisites

• Spec-Kit specification files describing the desired features
• Claude Code for AI-assisted development
• Understanding of CRUD operations and REST API concepts
• Development environment with appropriate tools for target platform
• Clear understanding of data models and relationships

Conceptual Implementation Framework

Specification Reading Capability

• Parse and interpret feature specifications from spec files
• Extract entity definitions, attributes, and relationships
• Identify required CRUD operations for each entity
• Map specification requirements to implementation patterns
• Validate specification completeness before starting implementation

Backend Route Generation Capability

• Generate RESTful API endpoints based on entity definitions
• Create appropriate HTTP methods (GET, POST, PUT, DELETE) for each operation
• Implement proper request/​response handling according to specification
• Generate request validation and error handling patterns
• Create data access layer methods matching specification requirements

Frontend Client Generation Capability

• Generate API client code for consuming CRUD endpoints
• Create data models matching backend entities
• Implement UI components for CRUD operations (forms, lists, etc.)
• Generate service layers for API communication
• Create state management patterns for frontend applications

Success Criteria Enforcement Capability

• Validate implementation against specification-defined success criteria
• Ensure all required functionality is implemented
• Verify that error handling matches specification requirements
• Confirm that data validation aligns with specification constraints
• Test that API responses conform to specified formats

Code Scaffolding Capability

• Generate consistent code structure following best practices
• Create standardized file organization patterns
• Implement reusable components and utilities
• Generate boilerplate code for common operations
• Maintain consistent coding standards across the application
