Automated safety checks
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

About this skill
What it does
The modern-javascript-patterns skill equips AI agents with knowledge of advanced JavaScript development practices, including ES6+ features, modular code organization, and design patterns like modules, closures, and asynchronous programming. It enables agents to write clean, maintainable, and scalable backend JavaScript applications.
When to use it
- You're building a Node.js-based backend service that requires robust architecture.
- Your team is adopting modern JavaScript standards and needs guidance on best practices.
- You want to refactor legacy JavaScript code into more modular and efficient patterns.
- You're preparing for an interview or assessment in full-stack or backend JavaScript development.
Key capabilities
- Mastery of ES6+ syntax (e.g., arrow functions, destructuring, modules)
- Understanding of asynchronous programming with Promises and async/await
- Familiarity with common design patterns such as module pattern, factory pattern, and observer pattern
- Best practices for writing modular, testable, and maintainable code
Example prompts
- "Explain how to implement the module pattern in modern JavaScript."
- "Write a function that uses async/await to fetch data from an API and handle errors gracefully."
- "What are the best practices for organizing large-scale Node.js applications?"
Tips & gotchas
- Ensure your environment supports ES6+ features, as older browsers or runtime environments may require transpilation.
- While this skill focuses on patterns, practical implementation often requires additional tools like Babel or TypeScript for compatibility and type safety.
