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 pluginagentmarketplace/custom-plugin-javascript at a5f7afe637.

    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 allows AI agents to understand and generate modern JavaScript code. It can assist with tasks ranging from writing simple functions to debugging complex applications, leveraging current language features and best practices. The agent can also help refactor existing codebases or explain the purpose of specific JavaScript snippets.

When to use it

  • Code Generation: Generate new JavaScript components or utility functions based on a description of their functionality.
  • Debugging Assistance: Identify potential errors in existing JavaScript code and suggest fixes.
  • Code Explanation: Explain what a given block of JavaScript code does, line by line.
  • Refactoring: Suggest improvements to existing JavaScript code for readability or performance.

Key capabilities

  • Modern JavaScript syntax understanding (ES6+)
  • Code generation
  • Debugging assistance
  • Code explanation
  • Refactoring suggestions

Example prompts

  • "Write a React component that displays a list of items fetched from an API."
  • "Explain what this JavaScript code does: const arr = [1, 2, 3]; const sum = arr.reduce((a, b) => a + b, 0);"
  • "Refactor this function to use arrow functions and template literals."

Tips & gotchas

The agent's effectiveness depends on the clarity of your prompts; be specific about desired functionality or areas for improvement. While it understands modern JavaScript, very old or obscure code might require additional context.
