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 failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • Declares what it does: failed

    No SKILL.md was found in the skill's directory.

    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 github/awesome-copilot at 6c4d33b9cf.

    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 enables AI agents to identify and extract repeated or complex code blocks into separate methods, improving readability, maintainability, and reusability in Java projects. It supports analyzing code structure and generating clean, well-named methods with appropriate parameters.

When to use it

  • Refactoring a large method that performs multiple tasks into smaller, focused functions
  • Identifying duplicated logic across different parts of the codebase
  • Preparing legacy Java code for better maintainability or testing

Key capabilities

  • Detects repeated or complex code segments in Java
  • Extracts identified code into new methods with meaningful names
  • Ensures proper parameter passing and method signatures
  • Maintains original functionality while improving code structure

Example prompts

  • "Extract the logic that validates user input into a separate method."
  • "Refactor this long method by breaking it down into smaller, reusable functions."
  • "Identify duplicated code blocks in this Java class and extract them into methods."

Tips & gotchas

  • Ensure your Java project is well-structured before using this skill for optimal results.
  • Review the extracted methods to confirm they align with naming conventions and functional intent.
