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

    No SKILL.md was found in the skill's directory.

    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 sickn33/agentic-awesome-skills at c808e6e480.

    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 equips AI agents with modern JavaScript patterns to write cleaner, more maintainable backend code. It enables the generation of functional, object-oriented, and modular solutions using contemporary syntax and best practices.

When to use it

  • Refactoring legacy JavaScript codebases to adopt ES6+ features like arrow functions and template literals.
  • Generating new backend modules that leverage modern class structures and destructuring assignments.
  • Improving code readability by applying current design patterns such as Promises and async/await.
  • Ensuring consistency across a project by enforcing modern standard conventions over older practices.

Key capabilities

  • Implements ES6+ syntax including arrow functions, const/let declarations, and template strings.
  • Utilizes modern module systems and class-based object-oriented programming structures.
  • Applies asynchronous patterns like Promises and async/await for non-blocking operations.
  • Enforces clean code principles to enhance maintainability and scalability of backend logic.

Example prompts

  • "Refactor this legacy Node.js function to use modern JavaScript patterns and arrow functions."
  • "Generate a new API endpoint handler using ES6 classes and async/await for better readability."
  • "Convert this callback-heavy codebase into one utilizing Promises and modern module exports."

Tips & gotchas

Ensure your target runtime environment supports the specific ES version required by the generated patterns. While these patterns improve code quality, verify compatibility if maintaining support for older Node.js versions or legacy browsers.
