Conciseness

The body is dense and lean — exact CLI invocations, the batch JSON input shape, a worked example with real output, and numbered fixes — but time-sensitive version/date details ('announced at WWDC25, June 2025; shipped Sept 2025 across iOS 26, iPadOS 26, macOS Tahoe...') appear in the intro and in Core Design Principles #1 outside any 'old patterns'/'deprecated' section, which the guidelines penalize. This is a minor, trimmable amount of over-explanation (anchor 4) rather than a broader tightness problem (anchor 3).

Actionability

Fully executable, copy-paste-ready guidance: three concrete subcommands with real expected output ('python3 scripts/hig_checker.py contrast "#8E8E93" "#FFFFFF" -> Contrast Ratio: 3.26 [FAILED]'), the batch JSON input shape, and a worked example whose fixes include specific values ('darken to >= #6E6E73 on white', 'expand the hit region to 44x44 with padding/contentShape'). Matches anchor 5; the examples cover the common audit cases.

Workflow Clarity

The Mode 1/Mode 2 sequence is clearly laid out with per-check pass/fail and scorecard thresholds (90-100 ship, 70-80 fix, <70 rework), but the batch-audit workflow lacks an explicit fix-then-re-run feedback loop: the worked example delivers findings and fixes without re-running 'hig_checker.py batch' to confirm the score recovers. The scoring notes cap workflow_clarity at 3 when feedback loops are missing in batch-operation contexts, so this cannot score 4 despite the otherwise clean sequencing.

Progressive Disclosure

The body's structure is well-designed — clearly signaled, one-level-deep references to 'references/visual-design.md', 'references/accessibility.md', 'references/platform-specifics.md', 'scripts/hig_checker.py', and 'templates/hig-audit-template.md' — but none of these files exist in the bundle (no references/, scripts/, assets/, or templates/ directories are present), so every referenced path dangles and navigation dead-ends. Scored against the actual bundle structure per the guidelines, the cross-file organization is unfulfilled: a 3 ('some structure but could be better organized'), not the 4-5 the design would earn if the files shipped.

Specificity

Lists multiple concrete actions — 'Audits and designs iOS/macOS/watchOS/visionOS interfaces against the Apple Human Interface Guidelines', 'checking contrast or tap-target sizes', 'designing native-feeling Apple UI' — with comprehensive coverage inside its niche. Matches the anchor-5 example pattern ('Extract text and tables from PDF files, fill forms, merge documents'); no minor gaps that would justify a 4.

Completeness

Explicitly answers both: what ('Audits and designs iOS/macOS/watchOS/visionOS interfaces against the Apple Human Interface Guidelines, including the Liquid Glass design language') and when ('Use when reviewing an Apple-platform mockup or app for HIG compliance, checking contrast or tap-target sizes, or designing native-feeling Apple UI') with concrete quoted trigger phrases. Exact match for anchor 5; the 'when' clause is fully explicit, so this is not the anchor-4 case of a weakly specified 'when'.

Trigger Term Quality

Comprehensive natural-term coverage: 'HIG compliance', 'contrast', 'tap-target sizes', 'Liquid Glass', all four platform names, plus quoted example utterances users would actually say ('audit my iOS app against the HIG', 'is this text readable on Liquid Glass?'). Synonym-style variants ('reviewing', 'checking', 'auditing') are all present; nothing significant is missing that would drop it to 4.

Distinctiveness Conflict Risk

Clear niche (Apple HIG / Liquid Glass / Apple platforms) with distinct triggers; uses third-person voice ('Audits and designs') as required. Overlap with generic UI-design skills is minimal because every trigger is platform- or HIG-scoped, matching the anchor-5 pattern rather than the 'minor overlap risk with closely related skills' of anchor 4.
