swiftui-expert-skill

Use when writing, reviewing, or refactoring SwiftUI code for iOS or macOS, including state management and `@Observable` data flow, view composition and invalidation/performance, lists and `ForEach` identity, environment usage, localization, animations, Liquid Glass adoption, migrating soft-deprecated APIs, or Instruments `.trace` capture/analysis for hangs, hitches, CPU hotspots, or excessive view updates.

Quality

Content

100%Weight 40%Scale 1-3

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is well-organized into operating rules, sequenced task workflows, a topic router, and a correctness checklist, with concrete executable commands and real one-level-deep reference files. It respects the context budget while remaining highly actionable.

DimensionReasoningScore

Conciseness

Lean and efficient: every line earns its place with no padding or explanation of basic SwiftUI concepts Claude already knows, and detailed material is deferred to reference files.

3 / 3

Actionability

Provides fully executable commands such as 'python3 "${SKILL_DIR}/scripts/record_trace.py" --list-devices' and concrete diagnostics ('main_running_coverage_pct inside each correlation (<25% = blocked; >=75% = CPU-bound)').

3 / 3

Workflow Clarity

Multi-step workflows are clearly sequenced with numbered steps, explicit decision logic, stop-file handling, and validation checkpoints such as 'Only edit code if the user asked for edits'.

3 / 3

Progressive Disclosure

Clear overview with a Topic Router table mapping each topic to a one-level-deep reference file, all of which exist as real bundle files, providing easy navigation without nested references.

Description

100%Weight 40%Scale 1-3

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is concise yet comprehensive, naming concrete capabilities and pairing them with an explicit 'Use when...' trigger. It is clearly distinguishable as a SwiftUI-specific skill and avoids vague language.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions such as 'writing, reviewing, or refactoring SwiftUI code', 'state management and `@Observable` data flow', 'lists and `ForEach` identity', 'Liquid Glass adoption', 'migrating soft-deprecated APIs', and 'Instruments `.trace` capture/analysis for hangs, hitches, CPU hotspots'.

3 / 3

Completeness

Explicitly answers both what (the enumerated capabilities) and when via the leading 'Use when writing, reviewing, or refactoring SwiftUI code...' trigger clause.

3 / 3

Trigger Term Quality

Good coverage of natural terms a user would actually say, including 'writing, reviewing, or refactoring SwiftUI code', 'state management', 'animations', 'localization', and 'Instruments'.

3 / 3

Distinctiveness Conflict Risk

Clearly scoped to SwiftUI for iOS/macOS with distinctive subtopics (Liquid Glass, ForEach identity, Instruments trace analysis) that make it unlikely to trigger for the wrong skill.
