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 steipete/agent-scripts at 3f8c6a33f9.

    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

The Swift Concurrency Expert skill enables AI agents to generate, refactor, and debug modern Swift code using the async/await syntax. It specifically handles tasks involving actors, global actors, and structured concurrency patterns to ensure thread-safe and efficient application logic.

When to use it

  • Refactoring legacy blocking code into non-blocking async functions for better UI responsiveness.
  • Generating robust actor-based models to manage shared state safely in multi-threaded environments.
  • Debugging race conditions or deadlocks caused by improper concurrency usage in iOS or macOS apps.
  • Creating complex task groups to orchestrate multiple asynchronous operations efficiently.

Key capabilities

  • Writing and optimizing async/await functions
  • Defining and implementing Actor types for data isolation
  • Utilizing Task, TaskGroup, and Sendable constraints
  • Managing global actors for system-wide coordination
  • Identifying concurrency violations and potential race conditions

Example prompts

  • "Convert this synchronous network request into an async function using Swift Concurrency."
  • "Create a new Actor to manage user session state safely across multiple threads."
  • "Refactor this code block to use TaskGroup for parallel image loading without blocking the main thread."

Tips & gotchas

Ensure your target Xcode version supports Swift concurrency features, as older versions may not compile actor definitions or async syntax. Always verify that types passed between actors conform to Sendable to prevent data races at runtime.
