Debug and optimize complex JavaScript concurrency issues with expert guidance from this specialized AI assistant.

Repository

Install on your platform

Showing Claude Code. One command installs this skill into any of the agents below.

Installs under a different name. Its SKILL.md names it Swift Concurrency Expert Guide, not the name it is listed under, so the command below uses that name.
  1. 1

    Run this in your project

    terminal
    $ npx skills add mosif16/codex-skills --skill "Swift Concurrency Expert Guide" -a claude-code

  2. Uses the open-source skills CLI and needs Node.js. Add -g to install it for your user instead of this project.

Install target

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 mosif16/codex-skills at f10bf9466c.

    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 expert guidance on Swift concurrency, enabling you to write efficient and responsive code. It can explain complex concepts like structured concurrency, async/await, and actors, and assist in debugging concurrent issues. The skill offers practical advice for optimizing performance and ensuring thread safety within Swift applications.

When to use it

  • Debugging asynchronous errors: When encountering unexpected behavior or crashes related to asynchronous operations in your Swift code.
  • Optimizing UI responsiveness: To identify and resolve bottlenecks that cause delays or freezes in user interface updates.
  • Understanding actor isolation: When needing help implementing data protection using actors and ensuring safe concurrent access.
  • Learning structured concurrency: If you're new to Swift concurrency and need a clear explanation of its core principles and best practices.

Key capabilities

  • Explains Swift concurrency concepts (async/await, actors)
  • Provides debugging assistance for asynchronous code
  • Offers advice on optimizing performance in concurrent applications
  • Guidance on implementing thread safety using actors

Example prompts

  • "Explain how to use async/await in Swift."
  • "I'm getting a deadlock error in my Swift app. Can you help me debug it?"
  • "How do I safely share data between multiple tasks using actors in Swift?"

Tips & gotchas

This skill assumes basic familiarity with Swift programming concepts. Complex concurrency issues may require providing detailed code snippets for accurate diagnosis and resolution.
