Conciseness

Every line is a directive with zero concept explanation or padding — specific values ('160–220ms for controls and 500–760ms for section entrances', 'slower than 14 seconds'), no filler, and full assumption of Claude's competence. Nothing to trim.

Actionability

Concrete, near-executable guidance: named ARIA roles ('tablist, tab, and tabpanel behavior', 'arrow-key movement plus Enter and Space selection'), explicit motion durations, and an exhaustive operational-state list ('loading, empty, disabled, stale slot, invalid details, payment failure, retry, reschedule, cancel, and success'). It stops short of 5 because no ready-made code or markup snippets are provided for the common cases.

Workflow Clarity

Clear sequence (Journey → Visual System → Page → Treatment Selector → Booking Flow → Motion) with an explicit validation checklist ('Test a stale slot, failed media, server error, invalid field, and retry', 'Confirm no layout shift', contrast/focus/zoom checks) and error-recovery loops ('Return focus to the correct field after an error', 'Preserve selections across Back navigation').

Progressive Disclosure

Well-organized sections all at overview level with no nested references and no bundle files to navigate; however the ~78-line body exceeds the <50-line simple-skill exception, and detailed implementation guidance (e.g. the treatment-selector accessibility pattern) is fully inline rather than split one level deep.

Specificity

Names the domain fully enumerated ('salons, barbers, spas, wellness studios, clinics, and hospitality brands') with concrete actions ('Create or redesign appointment-based service websites') and specific capability areas (treatment selectors, location-aware booking), but the action verbs are limited to create/redesign rather than comprehensive multi-action coverage.

Completeness

Both 'what' (create/redesign appointment-booking service websites) and 'when' (explicit 'Use for...' clause) are present, so it avoids the completeness cap of 3; however the 'when' clause enumerates design features rather than concrete user trigger scenarios, keeping it below a 5.

Trigger Term Quality

Natural user vocabulary like 'appointment', 'booking', 'salons', 'spas', 'clinics' is present, but common phrasings users would actually say ('book online', 'schedule an appointment', 'hair salon website') are missing.

Distinctiveness Conflict Risk

The appointment-based service website niche with editorial aesthetic triggers is distinct with domain-specific keywords; only minor overlap risk exists with general web-design or branding skills.
