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 dauquangthanh/hanoi-rainbow at 0e2ebaea02.

    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 refactors existing code to improve its readability, maintainability, and efficiency. It focuses on restructuring code without changing its external behavior. The skill aims to simplify complex logic, reduce redundancy, and adhere to best practices for cleaner and more robust software.

When to use it

  • Legacy Codebase Cleanup: Refactor a large, older codebase to improve developer understanding and reduce technical debt.
  • Improving Readability: Take poorly documented or convoluted code snippets and restructure them for better clarity.
  • Performance Optimization: Identify areas of inefficient code and refactor for improved execution speed.
  • Preparing for New Features: Refactor existing code before adding new features to ensure a clean integration path.

Key capabilities

  • Code Restructuring
  • Readability Improvement
  • Maintainability Enhancement
  • Efficiency Optimization

Example prompts

  • "Refactor this Python function to improve its readability and reduce complexity: [code snippet]"
  • "Can you refactor this JavaScript code block to remove redundant logic?"
  • "Optimize the performance of this Java method by refactoring it for better efficiency."

Tips & gotchas

The skill's effectiveness depends on providing clear, well-defined code snippets. Large or extremely complex files might require iterative refinement and multiple prompts.
