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 28 Sept 2026

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 dimillian/skills at 05ba982bfe.
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

The SwiftUI Performance Audit skill analyzes SwiftUI code to identify performance bottlenecks, such as unnecessary recomputation, inefficient view hierarchies, and memory leaks. It provides actionable recommendations for optimizing rendering speed and reducing resource usage in SwiftUI applications.

When to use it

Before releasing a SwiftUI app to ensure smooth user experience
After identifying slow UI behavior during testing or user feedback
When refactoring an existing SwiftUI project for better performance
To optimize complex views with multiple state dependencies

Key capabilities

Detects over-identification of @State and @ObservedObject usage
Identifies unnecessary view recomputation
Highlights inefficient use of modifiers and layout structures
Suggests improvements for memory management in SwiftUI apps

Example prompts

"Analyze this SwiftUI code for performance issues"
"Optimize the rendering speed of this SwiftUI view"
"Check for memory leaks in my SwiftUI app"

Tips & gotchas

Ensure your SwiftUI code is fully compiled and ready for analysis.
This skill works best with complete views or modules, not isolated snippets.
