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 jarrodwatts/claude-code-config at bb7e8b0843.

    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 provides access to the useEffect hook within React. The useEffect hook lets you perform side effects in functional components, such as data fetching, DOM manipulation, and subscriptions. It allows components to interact with the outside world.

When to use it

  • Fetching Data: Retrieve data from an API when a component mounts or specific dependencies change.
  • Setting up Subscriptions: Initialize and clean up event listeners or subscriptions based on component lifecycle events.
  • Directly Manipulating the DOM: Update elements outside of React's declarative control, though this is generally discouraged in favor of other approaches.
  • Synchronizing with External Systems: Keep external systems (like browser storage) in sync with your component’s state.

Key capabilities

  • Provides access to the useEffect hook.
  • Allows for side effects based on dependencies.
  • Supports cleanup functions to prevent memory leaks.

Example prompts

  • "Use useEffect to fetch user data from /api/users when the component mounts."
  • "Implement a subscription to window resize events using useEffect and clean it up when the component unmounts."
  • "Show me how to use useEffect to update the document title based on the current state."

Tips & gotchas

  • Ensure you understand React's lifecycle methods before utilizing useEffect, as it replaces many of their functionalities.
  • Be mindful of dependency arrays; incorrect dependencies can lead to unexpected behavior or infinite loops.
