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 fluid-tools/claude-skills at 4d09914bf5.

    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 and utilizes the useEffect hook in React. It allows AI agents to manage side effects within functional components, such as fetching data, directly updating the DOM, or setting up subscriptions. The agent can leverage this to create dynamic and interactive user interfaces based on external events or dependencies.

When to use it

  • Data Fetching: When an AI agent needs to retrieve data from an API after a component mounts.
  • DOM Manipulation: To directly modify the Document Object Model (DOM) in response to changes, like setting focus on an element when a component appears.
  • Subscription Management: When an AI agent needs to subscribe to events or external services and clean up those subscriptions when the component unmounts.

Key capabilities

  • useEffect hook integration
  • Dependency array management for useEffect
  • Cleanup function execution on unmount

Example prompts

  • "Create a React component that fetches user data from an API when it mounts and displays it."
  • "Write a React component that sets up a timer using useEffect to update the page title every 5 seconds."
  • "Generate code for a React component which subscribes to window resize events and updates a state variable accordingly, cleaning up on unmount."

Tips & gotchas

  • Requires a basic understanding of React functional components.
  • Be mindful of dependency arrays in useEffect – incorrect dependencies can lead to unexpected behavior or infinite loops.
