Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned clostaunau/holiday-card at d7c92b29e8.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

The java-best-practices skill equips AI agents with deep knowledge of Java coding standards, design patterns, and modern development workflows. It enables agents to generate clean, maintainable code that adheres to industry norms and best practices.

When to use it

  • Refactoring legacy Java codebases to improve readability and performance.
  • Generating new modules that follow SOLID principles and clean architecture.
  • Reviewing pull requests for adherence to coding standards and potential bugs.
  • Creating unit tests that cover edge cases and ensure robust application logic.

Key capabilities

  • Enforces strict adherence to Java naming conventions and formatting rules.
  • Applies design patterns like Factory, Singleton, and Observer correctly.
  • Integrates with modern build tools such as Maven and Gradle.
  • Generates idiomatic code compatible with Java 8 through Java 21 features.

Example prompts

  • "Generate a Spring Boot service that handles user authentication using JWT tokens."
  • "Refactor this legacy Java class to use dependency injection and reduce cyclomatic complexity."
  • "Write comprehensive JUnit 5 tests for a payment processing module with mock data."

Tips & gotchas

Ensure your AI agent has access to the latest Java documentation and library versions to avoid outdated recommendations. This skill is most effective when combined with specific project context, such as existing codebases or framework constraints.
