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 dimillian/skills at 05ba982bfe.

    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 enables AI agents to understand and implement concurrency patterns in Swift, including async/await, actors, and task management. It provides guidance on writing efficient, non-blocking code for iOS and macOS applications.

When to use it

  • You're developing a Swift app that requires asynchronous operations like network requests or file I/O.
  • You need to manage shared resources safely across multiple threads in a SwiftUI or UIKit project.
  • You want to optimize performance by parallelizing computationally intensive tasks.

Key capabilities

  • Explains Swift's concurrency model and its differences from traditional GCD and OperationQueue.
  • Offers best practices for using async/await, actors, and task groups.
  • Helps identify and resolve common concurrency issues like race conditions and deadlocks.

Example prompts

  • "How do I use async/await to fetch data from an API in Swift?"
  • "Can you explain how to safely share a mutable object between multiple threads using actors?"
  • "I'm getting a deadlock when using DispatchQueue; can you help me fix it?"

Tips & gotchas

  • Ensure your code is written for Swift 5.5 or later, as concurrency features are not available in earlier versions.
  • Avoid mixing traditional GCD with async/await unless necessary, to prevent complexity and potential bugs.
