Use when handling requests to diagnose slow rendering, janky scrolling, high CPU/memory usage, excessive view updates, or layout thrash in SwiftUI apps, and to provide guidance for user-run Instruments profiling when code review alone is insufficient. Audit and improve SwiftUI runtime performance….
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# SwiftUI Performance Audit ## Quick start Use this skill to diagnose SwiftUI performance issues from code first, then request profiling evidence when code review alone cannot explain the symptoms. ## Workflow 1. Classify the symptom: slow rendering, janky scrolling, high CPU, memory growth, hangs, or excessive view updates. 2. If code is available, start with a code-first review using `references/code-smells.md`. 3. If code is not available, ask for the smallest useful slice: target view, data flow, reproduction steps, and deployment target. 4. If code review is inconclusive or runtime evidence is required, guide the user through profiling with `references/profiling-intake.md`. 5. Summarize likely causes, evidence, remediation, and validation steps using `references/report-template.md`. ## 1. Intake Collect: - Target view or feature code. - Symptoms and exact reproduction steps. - Data flow: `@State`, `@Binding`, environment dependencies, and observable models. - Whether the issue shows up on device or simulator, and whether it was observed in Debug or Release. Ask the user to classify the issue if possible: - CPU spike or battery drain - Janky scrolling or dropped frames …

How to install
mdr add velimirmueller/lab-claude-skills/swiftui-performance-audit@sha256:7716e2128cd1b110The line at the top of this page pins the label git:20261028.88809da, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
