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 sjungling/claude-plugins at 0dd093bc8c.

    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 equips AI agents with specialized knowledge to generate, debug, and optimize Swift code for iOS development. It enables the creation of native applications leveraging Apple's latest frameworks and best practices.

When to use it

  • Building new native iOS applications from scratch using SwiftUI or UIKit.
  • Refactoring legacy Objective-C codebases into modern Swift syntax.
  • Debugging runtime errors, memory leaks, or UI rendering issues in Xcode projects.
  • Integrating third-party libraries like CoreML, ARKit, or HealthKit into existing apps.

Key capabilities

  • Writing idiomatic Swift code compliant with current Apple standards.
  • Generating complete project structures including Info.plist and entitlements.
  • Implementing MVVM architecture patterns for scalable app design.
  • Debugging complex concurrency issues using async/await and actors.
  • Optimizing performance metrics such as frame rate and memory usage.

Example prompts

"Create a SwiftUI todo list app with local data persistence using Core Data." "Fix this memory leak in my iOS view model where the observer isn't being cancelled." "Generate unit tests for a Swift function that handles user authentication tokens."

Tips & gotchas

Ensure your development environment matches the target iOS version specified in the generated code. Complex features like background tasks may require additional entitlements not automatically included in basic scaffolding.
