SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps you design, implement, and review Scala backend code with direct-style patterns instead of monadic boilerplate, so application logic stays clear, safe, and maintainable.

Core Features & Use Cases

  • Scala Project Setup: Start new direct-style Scala services with the right sbt, logging, formatting, and warning settings.
  • Concurrency and HTTP: Apply Ox for structured concurrency and Tapir for direct-style endpoints, authentication, error handling, and server configuration.
  • Data and Operations: Work through persistence, email delivery, Kafka, testing, OpenTelemetry, and OpenAPI generation with production-ready patterns.
  • Use Case: If you are building or reviewing a Scala 3 backend, this Skill can guide package structure, resource lifecycles, endpoint wiring, database transactions, and observability from start to finish.

Quick Start

Ask me to analyze your Scala codebase and I will apply the relevant direct-style chapter to help implement or review the next backend task.

FAQPage Schema
How do I build Scala 3 backends using direct-style instead of monads?▼

Structure Scala 3 projects for direct-style by configuring sbt with correct logging, formatting, and warning settings, then organizing package structures around endpoint wiring, resource lifecycles, and database transactions.

How do I handle concurrency and HTTP endpoints in direct-style Scala?▼

Implement direct-style Scala testing and observability by applying production-ready patterns for database transactions, OpenTelemetry integration, and OpenAPI generation to ensure robust backend operations.

Can I use Tapir with Ox for direct-style Scala backend development?▼

Direct-style Scala differs from monadic approaches by eliminating boilerplate, allowing application logic to remain clear and maintainable while preserving safety through Ox supervised scopes and explicit visibility.

What are the limitations of using direct-style for Scala backend services?▼

Direct-style Scala requires braceless Scala 3 syntax, explicit visibility modifiers, and strict adherence to Ox supervised scopes, meaning developers must follow these structural constraints to maintain safety and compile correctly.
