Conciseness

The 11 Key Principles are dense, substantive one-liners ("Toggles for binary states. On or off.", "2-5 items, roughly equal importance, short labels") with platform-specific facts Claude cannot be assumed to know. Minor trimmable waste keeps this at anchor 4 rather than 5: the body's first line duplicates the frontmatter description verbatim, the trailing "When to Use" section is pure filler ("This skill is applicable to execute the workflow or actions described in the overview."), and the branding footer adds tokens without guidance value.

Actionability

For an instruction-only skill the guidance is concrete and executable: "In Settings-style screens, changes take effect immediately. In modal forms, changes commit on confirmation", "Configure keyboard type to match expected input (email, URL, number)", "Display current value next to the stepper with reasonable min/max bounds", plus a four-part Output Format defining the deliverable. It falls short of anchor 5 only because there is no worked example of the recommended output and the validation guidance stays high-level.

Workflow Clarity

All workflow components exist (context check "before asking questions", a "Questions to Ask" intake list, decision principles with references, and an "Output Format"), but they are never sequenced into an explicit process — the document even places "Questions to Ask" after "Output Format", so the actual order (check context → ask → decide → produce output) must be inferred. This matches anchor 3 ("sequence present but checkpoints missing or implicit") rather than anchor 4's explicitly numbered steps.

Progressive Disclosure

The body is a genuine overview that keeps details in the bundle: the Reference Index table lists all 14 references with topic and key-content columns, every referenced path (controls.md, toggles.md, segmented-controls.md, sliders.md, steppers.md, pickers.md, combo-boxes.md, text-fields.md, text-views.md, labels.md, token-fields.md, virtual-keyboards.md, rating-indicators.md, gauges.md) was verified to exist in references/, and they are one level deep. This closely matches the anchor-5 pattern of a lean overview with well-signaled one-level-deep references.

Specificity

The explicit actions ("Check for .claude/apple-design-context.md before asking questions", "only ask for information not already covered") are concrete but describe an intake behavior rather than the skill's actual capabilities — the domain (Apple HIG, selection/input controls) is never named. The voice is imperative/second-person ("Check", "Use") rather than the required third person, which triggers the -1 penalty per the judging guidelines, bringing this from 2 to 1.

Completeness

There is no "Use when..." clause or equivalent trigger guidance (which alone caps completeness at 3), and the stated "what" — a context-file checking procedure — does not convey what the skill actually does (recommend Apple HIG selection and input controls). Both what-the-skill-does and when-to-use-it are effectively unanswered, matching anchor 2 ("Has a vague 'what' and no 'when'") better than anchor 3, whose 'what' clearly describes the skill's function.

Trigger Term Quality

Only one or two generic keywords ("context", "information", "questions") appear; the natural phrases a user would say when needing this skill (toggle, switch, slider, picker, segmented control, settings screen, Apple HIG, iOS/macOS form) are entirely absent. Anchor 2 ("One or two generic keywords; missing the natural phrases users say") is the best fit; anchor 1 is too harsh only because "apple-design-context.md" carries a faint domain signal.

Distinctiveness Conflict Risk

The text "Use existing context and only ask for information not already covered" could describe virtually any skill in a suite that shares this context-file convention, creating high overlap risk with the sibling hig-* skills listed in the body. The filename "apple-design-context.md" provides a weak domain signal, keeping this just above anchor 1's entirely-generic example ("Helps with code and documents").
