java-coding-standards
Java coding standards for Spring Boot and Quarkus services: naming, immutability, Optional usage, streams, exceptions, generics, CDI, reactive patterns, and project layout. Automatically applies framework-specific conventions.
npx skills add mturac/everything-openai-codex --skill java-coding-standards --agent codex
Same command for any agent — swap --agent for claude-code, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Java Coding Standards Standards for readable, maintainable Java (17+) code in Spring Boot and Quarkus services. ## When to Use - Writing or reviewing Java code in Spring Boot or Quarkus projects - Enforcing naming, immutability, or exception handling conventions - Working with records, sealed classes, or pattern matching (Java 17+) - Reviewing use of Optional, streams, or generics - Structuring packages and project layout - **[QUARKUS]**: Working with CDI scopes, Panache entities, or reactive pipelines ## How It Works ### Framework Detection Before applying standards, determine the framework from the build file: - Build file contains `quarkus` → apply **[QUARKUS]** conventions - Build file contains `spring-boot` → apply **[SPRING]** conventions - Neither detected → apply shared conventions only ## Core Principles - Prefer clarity over cleverness - Immutable by default; minimize shared mutable state - Fail fast with meaningful exceptions - Consistent naming and package structure - **[QUARKUS]**: Favor build-time over runtime processing; avoid runtime reflection where possible ## Examples The sections below show concrete Spring Boot, Quarkus, and shared Java examples for naming, im

What does the java-coding-standards skill do?
Java coding standards for Spring Boot and Quarkus services: naming, immutability, Optional usage, streams, exceptions, generics, CDI, reactive patterns, and project layout. Automatically applies framework-specific conventions.
How do I install it?
Run `npx skills add mturac/everything-openai-codex --skill java-coding-standards --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From mturac/everything-openai-codex, a repository with 84 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
