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 facebook/react at d083ec1da1.

    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

The flow skill enables static type checking in JavaScript code, helping developers catch errors early during development. It analyzes code structure and enforces type consistency across projects, improving reliability and maintainability.

When to use it

  • You're working on a large-scale JavaScript application where type safety is critical.
  • Your team wants to enforce consistent coding standards and reduce runtime errors.
  • You are integrating with tools or frameworks that benefit from static typing, such as React.

Key capabilities

  • Static type checking for JavaScript
  • Integration with build systems like Webpack or Babel
  • Support for React projects

Example prompts

  • "Check the types in my React components using Flow."
  • "Add Flow type annotations to this JavaScript file."
  • "Run a static type check on the entire project."

Tips & gotchas

  • Ensure your project is set up correctly with Babel and Webpack for Flow to work seamlessly.
  • Flow may not support all modern JavaScript features, so verify compatibility with your codebase.
