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 wondelai/skills at c172996495.

    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 AI agents guide code review and refactoring efforts by applying established refactoring patterns. It provides a disciplined approach to improving existing code's internal structure without altering its observable behavior, focusing on small, test-backed transformations. The goal is to reduce technical debt and prepare code for new features using named refactorings that address specific "code smells."

When to use it

  • During code reviews to identify areas needing improvement.
  • When preparing existing codebases for the addition of new features.
  • To systematically reduce technical debt within a project.
  • When encountering common code smells like Long Method or Duplicate Code.
  • To assess and improve the structural quality of code, aiming for a score of 10/10 based on defined principles.

Key capabilities

  • Code Smell Identification: Recognizes and names various code smells (e.g., Feature Envy, Long Method, Duplicate Code).
  • Refactoring Pattern Application: Suggests specific refactorings to address identified code smells.
  • Structural Quality Scoring: Evaluates code structure on a scale of 0-10 based on defined principles.
  • Provides Remediation Steps: Offers guidance on the steps needed to reach a structural quality score of 10/10.
  • Categorizes Smells: Groups smells into five families: Bloaters, Object-Orientation Abusers, Change Preventers, Dispensables, and Couplers.

Example prompts

  • "Review this code snippet for any code smells and suggest refactorings."
  • "Assess the structural quality of this function (provide code) and tell me how to improve it."
  • “What refactoring should I apply to address a ‘Long Method’?”

Tips & gotchas

  • The skill focuses on refactoring, not rewriting. It's about improving structure, not changing functionality.
  • Always ensure tests pass after applying any suggested refactorings.
  • This skill is designed for backend services and APIs workflows.
