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 aj-geddes/useful-ai-prompts at 3f5182cfd7.

    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

The design-patterns-implementation skill enables AI agents to generate code adhering to established software engineering principles. It ensures that frontend solutions utilize recognized architectural strategies like Singleton, Factory, and Observer to improve maintainability and scalability.

When to use it

  • Refactoring legacy monolithic components into modular structures with clear separation of concerns.
  • Generating boilerplate-heavy classes that require complex instantiation logic or state management.
  • Building event-driven systems where decoupling between UI updates and data sources is critical.
  • Creating reusable libraries or plugins that need to be extensible without modifying core code.

Key capabilities

  • Applies Gang of Four (GoF) design patterns specifically within frontend contexts.
  • Generates TypeScript or JavaScript code structures aligned with industry best practices.
  • Produces documentation explaining the rationale behind specific pattern choices in generated code.

Example prompts

  • "Implement a Singleton pattern for a global theme manager in React using TypeScript."
  • "Create a Factory method implementation to dynamically render different input field types based on user configuration."
  • "Refactor this unstructured Vue component into an Observer-based system to separate data fetching from UI rendering."

Tips & gotchas

Ensure your AI agent understands the specific framework constraints (e.g., React hooks vs. class components) when requesting pattern implementations, as generic patterns may require adaptation for modern frontend ecosystems. Overusing complex patterns in simple applications can introduce unnecessary overhead and reduce code readability.
