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

    SKILL.md has no YAML frontmatter, so it declares nothing machine-readable.

    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 doubleslashse/claude-marketplace at 4e5415cfae.

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

About this skill

What it does

This skill allows AI agents to apply the SOLID principles of object-oriented design. It helps analyze existing code or design new systems, ensuring maintainability, flexibility, and reduced complexity through adherence to single responsibility, open/closed principle, Liskov substitution, interface segregation, and dependency inversion. The agent can identify violations of these principles and suggest refactoring strategies.

When to use it

  • Code Review: Have the agent analyze a codebase for SOLID principle violations before merging changes.
  • Design New Systems: Use the skill during the design phase to ensure new systems are built with maintainability in mind.
  • Refactoring Existing Code: Identify areas of code that would benefit from refactoring to improve its structure and reduce technical debt.
  • Learning SOLID Principles: Ask the agent to explain a specific principle or provide examples of how it applies to common design patterns.

Key capabilities

  • Applies Single Responsibility Principle (SRP)
  • Enforces Open/Closed Principle (OCP)
  • Validates Liskov Substitution Principle (LSP)
  • Checks for Interface Segregation Principle (ISP)
  • Implements Dependency Inversion Principle (DIP)

Example prompts

  • "Analyze this code snippet and identify any SOLID principle violations: [code]"
  • "Explain the Open/Closed Principle with a practical example."
  • "How can I refactor this class to adhere to the Single Responsibility Principle?"

Tips & gotchas

The agent's effectiveness depends on providing clear, well-structured code. While it understands object-oriented design concepts, familiarity with those concepts will help you interpret its suggestions and apply them effectively.
