Conciseness

The body is dense with actionable specifics ("3x-5x differences, not 1.5x", "900 weights with 200 weights", "100-200px gaps, not 20-40px") and wastes no tokens explaining concepts Claude already knows. It falls short of lean-perfection because the "bold means distinctive, not 'more effects'" point is stated twice (the AI SLOP TRAP warning and the closing test) and the purple-gradient warning is repeated across sections, plus a motivational closing paragraph that could be trimmed.

Actionability

Concrete, executable parameters appear throughout ("60% of the design", "50-100ms delays", "ease-out-quart/quint/expo", "70/30, 80/20 splits") — specific guidance far beyond high-level hints, and the code-absence is acceptable for an instruction-only design skill. Minor gaps keep it from 5: no worked before/after example of applying tactics to real code, and font choices are deferred to "see frontend-design skill for inspiration" without a bundled reference.

Workflow Clarity

A clear sequence is present (MANDATORY PREPARATION → Assess Current State → Plan Amplification → Amplify the Design → Verify Quality) with an explicit verification checklist ("Still functional", "NOT AI slop... If yes, start over") and an AskUserQuestion checkpoint for missing context. Not a 5 because the recovery path is only 'start over' rather than a targeted fix-and-recheck loop, and verification criteria are subjective rather than checkable.

Progressive Disclosure

Sections are well organized with clear headers, but all ~110 lines of per-dimension tactic lists (typography, color, spatial, effects, motion, composition) are inlined in SKILL.md with no reference files at all (no references/, scripts/, or assets/ exist). The detailed tactic checklists could be split into one-level-deep reference files; this is above the 'minimal structure' anchor but does not reach 'good structure with content appropriately placed' since nothing is offloaded and the body exceeds the under-50-line simple-skill case.

Specificity

"Amplify safe or boring designs to make them more visually interesting and stimulating. Increases impact while maintaining usability." names the design domain and 1-2 goal-level actions but lists no concrete capabilities (e.g., typography scale contrast, color intensification, motion choreography), matching the 'names domain and 1-2 concrete actions, but not comprehensive' anchor. It is not a 4 because there is no enumeration of several specific actions, and not a 2 because the language is concrete about what is done rather than generic.

Completeness

It explicitly answers both questions: what ("Amplify safe or boring designs... Increases impact while maintaining usability") and when ("Use when the user says the design looks bland, generic, too safe, lacks personality...") with concrete trigger phrases, exactly matching the top anchor.

Trigger Term Quality

The trigger clause "Use when the user says the design looks bland, generic, too safe, lacks personality, or wants more visual impact and character" contains multiple natural user-voice phrases — good keyword coverage. It falls short of the comprehensive-synonyms anchor because common variations users would equally say (e.g., "boring", "dull", "make it pop", "spice it up") are absent from the trigger clause.

Distinctiveness Conflict Risk

The niche — amplifying existing safe/boring designs — has distinct triggers ("bland", "too safe", "lacks personality") unlikely to fire for the wrong skill, with only minor overlap risk against general frontend-design or redesign skills. Not a 5 because "visual impact" and "design" territory broadly overlaps with those related skills.
