Automated safety checks

scanned 11 Oct 2026

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.

About this skill

What it does

This skill provides guidance on using useEffect in React for managing side effects, such as data fetching, subscriptions, or manually manipulating the DOM. It helps developers understand when and how to apply useEffect effectively within functional components.

When to use it

You need to perform data fetching after a component mounts.
You want to subscribe to an event or API in a React component.
You're trying to clean up resources, such as timers or subscriptions, before a component unmounts.

Key capabilities

Explains the basics of useEffect and its parameters.
Demonstrates common use cases like fetching data on mount.
Shows how to handle cleanup with return statements in useEffect.

Example prompts

"How do I fetch data using useEffect in React?"
"Can you show me an example of cleaning up a subscription in useEffect?"
"What's the correct way to use useEffect for updating the DOM?"

Tips & gotchas

Always include dependencies in the second argument of useEffect to avoid unexpected behavior.
Be mindful of infinite loops if useEffect updates state that triggers re-renders.
