appkit-interop

Decide when and how to bridge a macOS app from SwiftUI into AppKit. Use when implementing NSViewRepresentable or NSViewControllerRepresentable, accessing NSWindow or the responder chain, presenting panels, customizing menus, or handling desktop behaviors that SwiftUI does not model cleanly.

Quality

Content

100%

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

The body is a tight decision-routing skill: it tells Claude when to bridge, which bridge type to pick, where ownership lies, and what risks to validate, then delegates executable detail to four real one-level references. It respects the context budget while remaining concrete and actionable.

DimensionReasoningScore

Conciseness

Lean and efficient with no explanation of what SwiftUI or AppKit is; every section (Quick Start, Choose The Smallest Bridge, Workflow, References, Guardrails, Output Expectations) earns its place and assumes Claude's competence.

3 / 3

Actionability

Provides concrete decision rules ("Use NSViewRepresentable when you need a specific AppKit view with lightweight lifecycle needs", "SwiftUI owns value state... AppKit objects stay inside the representable") that are directly actionable; executable code is intentionally deferred to verified references, which the instruction-only note permits when guidance is actionable.

3 / 3

Workflow Clarity

A clearly sequenced 5-step workflow with an explicit validation step (step 5: "Validate lifecycle assumptions"); the missing validate-fix-retry loop is not penalized because this is a non-destructive design-decision skill outside the destructive/batch scope the rubric caps.

3 / 3

Progressive Disclosure

A concise overview with four well-signaled one-level-deep references, each with a one-line description and all verified to exist as real files (representables.md, window-panels.md, responder-menus.md, drag-drop-pasteboard.md); content is appropriately split with easy navigation.

Description

100%

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

A precise, third-person description that states concrete capabilities and provides an explicit "Use when" trigger covering the main AppKit interop entry points. It is concise without fluff and unlikely to fire for unrelated skills.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — "implementing NSViewRepresentable or NSViewControllerRepresentable, accessing NSWindow or the responder chain, presenting panels, customizing menus" — matching the anchor for several specific concrete actions rather than vague language.

3 / 3

Completeness

Explicitly answers both what ("Decide when and how to bridge a macOS app from SwiftUI into AppKit") and when ("Use when implementing..."), with an explicit trigger clause rather than implied timing.

3 / 3

Trigger Term Quality

Uses the exact terms a macOS developer would naturally say (NSViewRepresentable, NSViewControllerRepresentable, NSWindow, responder chain, panels, menus, SwiftUI, AppKit); not generic jargon but genuine domain trigger words.

3 / 3

Distinctiveness Conflict Risk

The SwiftUI-to-AppKit bridging niche with AppKit-specific triggers (NSWindow, responder chain, panels) is clearly distinct from a general SwiftUI skill; it scopes itself to "behaviors that SwiftUI does not model cleanly."
