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 avdlee/swift-concurrency-agent-skill at d5770817d2.

    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 swift-concurrency skill enables AI agents to understand and implement concurrency patterns in Swift, including asynchronous programming with async/await, managing concurrent tasks using Task, and handling cancellations or dependencies between operations. It provides guidance on writing efficient and safe multithreaded code for iOS and macOS applications.

When to use it

  • You're developing a Swift app that requires background processing without freezing the UI.
  • You need to handle multiple network requests simultaneously in an iOS application.
  • Your app needs to manage complex task dependencies or cancellations during asynchronous operations.

Key capabilities

  • Understanding and implementing async/await syntax for asynchronous code.
  • Managing concurrency with Task, DispatchQueue, and OperationQueue.
  • Handling cancellable tasks and managing their lifecycle.
  • Writing safe, non-blocking UI updates in Swift apps.

Example prompts

  • "How do I perform multiple network requests concurrently in Swift?"
  • "Can you show me how to use async/await for fetching data from an API in SwiftUI?"
  • "I need help managing task dependencies using Swift concurrency."

Tips & gotchas

  • Ensure your code is written with proper error handling and thread safety when using concurrency.
  • Avoid overusing global queues or dispatching too many tasks at once, which can lead to performance issues.
