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 dagba/ios-mcp at 526306aff8.

    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 swiftui-performance-audit skill enables AI agents to analyze SwiftUI applications for runtime performance bottlenecks, memory leaks, and rendering inefficiencies. It provides actionable insights to optimize user interface responsiveness and resource consumption in iOS projects.

When to use it

  • Diagnosing frame drops or stuttering during complex UI animations.
  • Identifying excessive memory usage caused by retained views or large image assets.
  • Optimizing layout calculations that trigger frequent view recompositions.
  • Pre-launch profiling to ensure the app meets strict performance benchmarks.

Key capabilities

  • Runtime analysis of SwiftUI view hierarchies and rendering cycles.
  • Detection of memory retention issues specific to iOS frameworks.
  • Identification of inefficient @State or @ObservedObject usage patterns.
  • Generation of targeted code recommendations for performance improvements.

Example prompts

  • "Audit my SwiftUI login screen for potential frame drops during image loading."
  • "Analyze the memory footprint of this shopping cart view and suggest leak fixes."
  • "Identify layout inefficiencies in this list-based dashboard that cause scrolling lag."

Tips & gotchas

Ensure your development environment matches the target iOS version to avoid false positives regarding deprecated APIs. Focus on complex views with high-frequency updates for the most accurate audit results.
