SwiftUI performance: render, scroll, CPU/memory, updates, layout, Instruments.
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 _Attribution: copied from @Dimillian’s `Dimillian/Skills` (2025-12-31)._ ## Overview Audit SwiftUI view performance end-to-end, from instrumentation and baselining to root-cause analysis and concrete remediation steps. ## Workflow Decision Tree - If the user provides code, start with "Code-First Review." - If the user only describes symptoms, ask for minimal code/context, then do "Code-First Review." - If code review is inconclusive, go to "Guide the User to Profile" and ask for a trace or screenshots. ## 1. Code-First Review Collect: - Target view/feature code. - Data flow: state, environment, observable models. - Symptoms and reproduction steps. Focus on: - View invalidation storms from broad state changes. - Unstable identity in lists (`id` churn, `UUID()` per render). - Heavy work in `body` (formatting, sorting, image decoding). - Layout thrash (deep stacks, `GeometryReader`, preference chains). - Large images without downsampling or resizing. - Over-animated hierarchies (implicit animations on large trees). Provide: - Likely root causes with code references. - Suggested fixes and refactors. …

How to install
mdr add steipete/agent-scripts/swiftui-performance-audit@sha256:594a38f2568ed65eThe line at the top of this page pins the label git:20260509.51ee7e5, 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.
