BF swiftui-performance-audit

Audit and improve SwiftUI runtime performance from code review and architecture. Use for 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.

This is a copy of a skill from another catalog; the rating counts the canonical one: swiftui-performance-audit (ClawHub)

How to improve

  1. The text references files that are not there: add them or drop the references.
For the model run — optional
  • Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
  • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Will not run. References files that are not bundled: references/optimizing-swiftui-performance-instruments.md, references/understanding-improving-swiftui-performance.md, references/understanding-hangs-in-your-app.md
  • 0Tools and files. 4 referenced file(s) missing: references/optimizing-swiftui-performance-instruments.md, references/understanding-improving-swiftui-performance.md, references/understanding-hangs-in-your-app.md
  • 0Result and completion. Does not say what the result is
  • 0Inputs and preconditions. Does not say what the process needs to start
  • 0Progress reporting. Says nothing while it works
  • 20When it triggers. No condition that starts the skill
  • 30Running it twice. 1 mutating operations with no state check
  • 40Consistency. Frontmatter name (swiftui-performance-audit) differs from the folder (timeflow-swiftui-performance-audit)
  • 70Failures and branches. 4 branches
  • 85Steps. 42 steps, 2 vague phrases
  • 100Execution cost. Instruction body is 1404 tokens
  • low 10 top-level sections: this looks like several domains in one skill

Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.

Quality signals

  • +5Description has no quoted example phrases that should trigger the skill
  • +4Description does not say when NOT to use the skill (false activations)
  • +3Output format is not stated: the model decides each time
  • +1No license
  • +2Single-language instructions
  • +3Description length 322: enough signal without eating the budget
  • +4Structure: 19 headings
  • +3Step-by-step instructions: 42 items
  • +4Has examples (11 code blocks)

Quality base 70; lint remarks subtract, signals add up to 100. Result: 70.
