This skill enables Claude to generate ORM models and database schemas. It is triggered when the user requests the creation of ORM models, database schemas, or wishes to generate code for interacting with databases. The skill supports various ORMs including TypeORM, Prisma, Sequelize, SQLAlchemy, Django ORM, Entity Framework, and Hibernate. Use this skill when the user mentions terms like "ORM model", "database schema", "generate entities", "create migrations", or specifies a particular ORM framework like "TypeORM entities" or "SQLAlchemy models". It facilitates both database-to-code and code-to-database schema generation.

Use when creating API services for backend communication with proper patterns for caching, error handling, and type safety.

Terraform IaC handler - centralized Terraform operations including init, validate, plan, apply, and destroy. Provides standard interface for Terraform-specific logic used by all infrastructure skills. Handles Terraform initialization, backend configuration, variable files, and execution plan management.

Generate organizational hierarchy charts from CSV, JSON, or nested data. Supports multiple layouts, department coloring, and PNG/SVG/PDF export.

Activates when user needs help writing documentation, README files, API docs, or code comments. Triggers on "write documentation", "create README", "document this API", "add JSDoc", "explain this code", "write docstrings", or documentation-related requests.

Build type-safe APIs with Hono - fast, lightweight routing for Cloudflare Workers, Deno, Bun, and Node.js. Set up routing patterns, middleware composition, request validation (Zod/Valibot/Typia/ArkType), RPC client/server with full type inference, and error handling with HTTPException. Use when: building APIs with Hono, setting up request validation with schema libraries, creating type-safe RPC client/server communication, implementing custom middleware chains, handling errors with HTTPException, extending context with custom variables, or troubleshooting middleware type inference issues, validation hook confusion, RPC performance problems, or middleware response typing errors.

Kotlin testing with JUnit 5, MockK, Spring test slices, and fast feedback commands. Provides single test execution, incremental builds, and JetBrains MCP integration for rapid TDD cycles. Use when writing tests for Kotlin/Spring code, running specific tests, or debugging test failures.

This skill should be used when the user asks about "PostgreSQL", "Postgres", "database optimization", "indexes", "PostgreSQL features", "JSONB", "full-text search", or PostgreSQL-specific Rails patterns. Load this skill when working with PostgreSQL databases.
