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 megastep/codex-skills at f6c3c49416.

    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 allows AI agents to generate Swift code, debug existing Swift projects, and explain complex Swift concepts. It can also assist in converting Objective-C code to Swift, making legacy project migrations easier. The agent leverages its knowledge of the Swift language, frameworks like SwiftUI and UIKit, and common coding patterns.

When to use it

  • Swift Development: Generate snippets or complete modules for iOS, macOS, watchOS, or tvOS applications.
  • Debugging: Identify and fix errors in existing Swift codebases.
  • Code Conversion: Translate Objective-C code into equivalent Swift implementations.
  • Learning Swift: Get explanations of specific Swift language features or frameworks.
  • Refactoring: Improve the structure and readability of Swift projects.

Key capabilities

  • Swift Code Generation
  • Debugging Assistance
  • Objective-C to Swift Conversion
  • Swift Language Explanation
  • Framework Support (SwiftUI, UIKit)

Example prompts

  • "Write a SwiftUI view that displays a list of items fetched from an API."
  • "Debug this Swift code: [paste code here]"
  • "Convert the following Objective-C method to Swift: [paste code here]"
  • "Explain how closures work in Swift."

Tips & gotchas

The agent's performance is best when provided with clear and concise prompts. While it supports a wide range of Swift concepts, very niche or bleeding-edge libraries might require additional context for optimal results.
