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 cin12211/orca-q at 3142fe610b.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill

What it does

The Refactoring Expert skill automatically improves existing backend code's structure, readability, and efficiency using proven refactoring techniques. It focuses on detecting code smells (common programming issues) and applying appropriate solutions without altering the external behavior of the application. The tool specializes in systematic code improvement through pattern matching and analysis to optimize codebase structure.

When to use it

  • When you have a large codebase that needs cleaning up and improving.
  • To address specific "code smells" like long methods, duplicated code, or excessive coupling between classes.
  • As part of an ongoing effort to maintain high-quality code standards within a development team.
  • Before introducing new features to ensure the existing code is well-structured and easy to understand.
  • To improve performance by identifying and correcting inefficient coding patterns.

Key capabilities

  • Code Smell Detection: Identifies common code smells using pattern matching (e.g., long methods, duplicated code).
  • Refactoring Technique Application: Applies appropriate refactoring techniques incrementally (e.g., Extract Method, Inline Method, Move Method).
  • Systematic Approach: Follows a safe refactoring process: ensuring tests exist, making small changes, running tests, committing if successful, and repeating.
  • Project Setup Detection: Checks for Node.js, TypeScript, ESLint, Jest, and Vitest configurations.

Example prompts

  • "Refactor this code to improve its readability." (followed by providing a code snippet)
  • "Identify any long methods in the codebase."
  • "Find duplicated code patterns within these files: file1.js, file2.ts."

Tips & gotchas

  • The skill may recommend specialist subagents for specific issues, such as performance bottlenecks (react-performance-expert), type system problems (typescript-type-expert), or database schema design (database-expert).
  • It's crucial to have existing tests in place before refactoring. The tool will create them if missing.
  • The skill operates incrementally, making small changes and validating each step to ensure the behavior remains unchanged.
