Java Backend Coding Technology (JBCT)

概要

The Java Backend Coding Technology (JBCT) skill provides a comprehensive methodology for creating robust and maintainable Java backend applications. It enforces a functional programming style centered around four monadic return types (Result, Option, Promise, T), the 'Parse, Don't Validate' pattern, and six core structural patterns for organizing logic. Use this skill for guidance on designing functional architecture, implementing use cases, handling errors without exceptions, ensuring thread safety, and reviewing code for compliance with JBCT standards. It also integrates with a companion CLI tool for automated formatting and linting.
