CRUD Skill

Auto-generates CRUD functionality for specified entities (tables) at production-ready level.

Quick Reference

  • "Create CRUD for task management" → /crud tasks
  • "Want search and pagination too" → Includes all together
  • "Include permissions (who can view/edit)" → Sets up authorization/rules together

Deliverables

  • CRUD + validation + authorization + tests, complete production-safe set
  • Minimize diff to match existing DB/code

Features:

  • Validation (Zod) auto-add
  • Auth/authorization (Row Level Security) auto-config
  • Relations (one-to-many, many-to-many) support
  • Pagination, search, filters
  • Auto-generated test cases

Auto-invoke Skills

This skill must explicitly invoke the following skills with the Skill tool:

| Skill | Purpose | When to Call | |-------|---------|--------------| | impl | Implementation (parent skill) | CRUD feature implementation | | verify | Verification (parent skill) | Post-implementation verification |


Execution Flow

Detailed steps are described in the phases below.

Phase 1: Entity Analysis

  1. Parse entity name from $ARGUMENTS
  2. Detect existing schema (Prisma, Drizzle, raw SQL)
  3. Infer field types and relations

Phase 2: CRUD Generation

  1. Generate model/schema if needed
  2. Create API endpoints (REST or tRPC)
  3. Add validation schemas (Zod)
  4. Configure authorization rules

Phase 3: Test Generation

  1. Create unit tests for each endpoint
  2. Add integration tests
  3. Generate test fixtures

Phase 4: Verification

  1. Run type check
  2. Run tests
  3. Verify build

Supported Frameworks

| Framework | Detection | Generated Files | |-----------|-----------|-----------------| | Next.js + Prisma | prisma/schema.prisma | API routes, Prisma client | | Next.js + Drizzle | drizzle.config.ts | API routes, Drizzle queries | | Express | express in package.json | Controllers, routes | | Hono | hono in package.json | Route handlers |
