Chachamaru127 Claude Code Harness Crud

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

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
