Checked
nguyenhuuca·vlatest·backend

Refactors complex Python/Java backend code for improved readability, efficiency, and maintainability using proven design patterns.

Repository

Install on your platform

This skill no longer installs under the name refactoring-code. nguyenhuuca/assessment has no skill named "refactoring-code" any more. It was renamed, moved or deleted upstream.

We check each listing against its upstream repository with the rules the skills CLI uses, last on 2026-10-23. We don't show a command we know will fail.

Install target

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 nguyenhuuca/assessment at d42ad12cdd.

    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 helps improve code quality and maintainability through automated refactoring. It can identify areas of duplicated code, suggest improvements to variable names, and restructure complex functions into smaller, more manageable units. The goal is to produce cleaner, more readable, and efficient code while preserving functionality.

When to use it

  • Legacy Codebases: Refactor older code that's difficult to understand or maintain.
  • Code Duplication: Identify and eliminate redundant code blocks within a project.
  • Complex Functions: Break down large, monolithic functions into smaller, more focused units.
  • Improving Readability: Enhance the clarity and readability of existing code for better collaboration.

Key capabilities

  • Automated refactoring suggestions
  • Code duplication detection
  • Variable renaming recommendations
  • Function restructuring

Example prompts

  • "Refactor this function to improve its readability." (followed by code)
  • "Find and eliminate duplicated code blocks in this file." (followed by code)
  • "Suggest better variable names for these variables: x, y, z." (followed by code)

Tips & gotchas

This skill is most effective when provided with well-formatted code. While it aims to preserve functionality, always review the suggested changes carefully before applying them.
