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 jabrena/cursor-rules-java at 8ac07fb219.

    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

What it does

This skill assists with refactoring Java codebases, leveraging modern Java features to improve readability and maintainability. It can identify opportunities for simplification, extract methods, and apply design patterns. The agent uses this skill to modernize legacy code and adhere to current best practices.

When to use it

  • You need to clean up a large, complex Java class with duplicated logic.
  • You want to convert procedural code into more object-oriented structures using design patterns.
  • A codebase needs modernization to take advantage of recent Java language features (e.g., records, sealed classes).
  • You're facing performance bottlenecks in existing Java methods and need assistance optimizing them.

Key capabilities

  • Method extraction
  • Design pattern application
  • Simplification of complex logic
  • Modern Java feature utilization

Example prompts

  • "Refactor this method to use a record instead of a getter/setter pair."
  • "Extract the duplicated code in this class into a separate helper function."
  • "Apply the Strategy pattern to handle different payment processing methods."

Tips & gotchas

This skill assumes familiarity with Java programming and basic refactoring principles. The agent may require context about existing design choices or constraints within the project.
