Overview

Validates UX design documents before they enter the implementation pipeline. Acts as the quality gate between UX Design and Visual Design/Implementation in the /team-ui pipeline.

Run this skill:

• After completing a UX spec with /ux-design
• Before handing off to ui-programmer or art-director
• Before the Pre-Production to Production gate check (which requires key screens to have reviewed UX specs)
• After major revisions to a UX spec

Verdict levels:

• APPROVED — spec is complete, consistent, and implementation-ready
• NEEDS REVISION — specific gaps found; fix before handoff but not a full redesign
• MAJOR REVISION NEEDED — fundamental issues with scope, player need, or completeness; needs significant rework

Phase 1: Parse Arguments

• Specific file path (e.g., /ux-review design/ux/inventory.md): validate that one document
• all: find all files in design/ux/ and validate each
• hud: validate design/ux/hud.md specifically
• patterns: validate design/ux/interaction-patterns.md specifically
• No argument: ask the user which spec to validate

For all, output a summary table first (file | verdict | primary issue) then full detail for each.

Phase 2: Load Cross-Reference Context

Before validating any spec, load:

1. Input & Platform config: Read .claude/docs/technical-preferences.md and extract ## Input & Platform. This is the authoritative source for which input methods the game supports — use it to drive the Input Method Coverage checks in Phase 3A, not the spec's own header. If unconfigured, fall back to the spec header.
2. The accessibility tier committed to in design/accessibility-requirements.md (if it exists)
3. The interaction pattern library at design/ux/interaction-patterns.md (if it exists)
4. The GDDs referenced in the spec's header (read their UI Requirements sections)
5. The player journey map at design/player-journey.md (if it exists) for context-arrival validation

Phase 3A: UX Spec Validation Checklist

Run all checks against a ux-spec.md-based document.

Completeness (required sections)

• Document header present with Status, Author, Platform Target
• Purpose & Player Need — has a player-perspective need statement (not developer-perspective)
• Player Context on Arrival — describes player's state and prior activity
• Navigation Position — shows where screen sits in hierarchy
• Entry & Exit Points — all entry sources and exit destinations documented
• Layout Specification — zones defined, component inventory table present
• States & Variants — at minimum: loading, empty/populated, and error states documented
• Interaction Map — covers all target input methods (check platform target in header)
• Data Requirements — every displayed data element has a source system and owner
• Events Fired — every player action has a corresponding event or null explanation
• Transitions & Animations — at least enter/exit transitions specified
• Accessibility Requirements — screen-level requirements present
• Localization Considerations — max character counts for text elements
• Acceptance Criteria — at least 5 specific testable criteria

Quality Checks

Player Need Clarity

• Purpose is written from player perspective, not system/developer perspective
• Player goal on arrival is unambiguous ("The player arrives wanting to ___")
• The player context on arrival is specific (not just "they opened the inventory")

Completeness of States

• Error state is documented (not just happy path)
• Empty state is documented (no data scenario)
• Loading state is documented if the screen fetches async data
• Any state with a timer or auto-dismiss is documented with duration

Input Method Coverage

• If platform includes PC: keyboard-only navigation is fully specified
• If platform includes console/gamepad: d-pad navigation and face button mapping documented
• No interaction requires mouse-like precision on gamepad
• Focus order is defined (Tab order for keyboard, d-pad order for gamepad)

Data Architecture

• No data element has "UI" listed as the owner (UI must not own game state)
• Update frequency is specified for all real-time data (not just "realtime" — what triggers update?)
• Null handling is specified for all data elements (what shows when data is unavailable?)

Accessibility

• Accessibility tier from accessibility-requirements.md is matched or exceeded
• If Basic tier: no color-only information indicators
• If Standard tier+: focus order documented, text contrast ratios specified
• If Comprehensive tier+: screen reader announcements for key state changes
• Colorblind check: any color-coded elements have non-color alternatives

GDD Alignment

• Every GDD UI Requirement referenced in the header is addressed in this spec
• No UI element displays or modifies game state without a corresponding GDD requirement
• No GDD UI Requirement is missing from this spec (cross-check the referenced GDD sections)

Pattern Library Consistency

• All interactive components reference the pattern library (or note they are new patterns)
• No pattern behavior is re-specified from scratch if it already exists in the pattern library
• Any new patterns invented in this spec are flagged for addition to the pattern library

Localization

• Character limit warnings present for all text-heavy elements
• Any layout-critical text has been flagged for 40% expansion accommodation

Acceptance Criteria Quality

• Criteria are specific enough for a QA tester who hasn't seen the design docs
• Performance criterion present (screen opens within Xms)
• Resolution criterion present
• No criterion requires reading another document to evaluate

Phase 3B: HUD Validation Checklist

Run all checks against a hud-design.md-based document.

Completeness

• HUD Philosophy defined
• Information Architecture table covers ALL systems with UI Requirements in GDDs
• Layout Zones defined with safe zone margins for all target platforms
• Every HUD element has a full specification (zone, visibility trigger, data source, priority)
• HUD States by Gameplay Context covers at minimum: exploration, combat, dialogue/cutscene, paused
• Visual Budget defined (max simultaneous elements, max screen %)
• Platform Adaptation covers all target platforms
• Tuning Knobs present for player-adjustable elements

Quality Checks

• No HUD element covers the center play area without a visibility rule to hide it
• Every information item that exists in any GDD is either in the HUD or explicitly categorized as "hidden/demand"
• All color-coded HUD elements have colorblind variants
• HUD elements in the Feedback & Notification section have queue/priority behavior defined
• Visual Budget compliance: total simultaneous elements is within budget

GDD Alignment

• All systems in design/gdd/systems-index.md with UI category have representation in HUD (or justified absence)

Phase 3C: Pattern Library Validation Checklist

• Pattern catalog index is current (matches actual patterns in document)
• All standard control patterns are specified: button variants, toggle, slider, dropdown, list, grid, modal, dialog, toast, tooltip, progress bar, input field, tab bar, scroll
• All game-specific patterns needed by current UX specs are present
• Each pattern has: When to Use, When NOT to Use, full state specification, accessibility spec, implementation notes
• Animation Standards table present
• Sound Standards table present
• No conflicting behaviors between patterns (e.g., "Back" behavior consistent across all navigation patterns)

Phase 4: Output the Verdict

## UX Review: [Document Name]
**Date**: [date]
**Reviewer**: ux-review skill
**Document**: [file path]
**Platform Target**: [from header]
**Accessibility Tier**: [from header or accessibility-requirements.md]

### Completeness: [X/Y sections present]
- [x] Purpose & Player Need
- [ ] States & Variants — MISSING: error state not documented

### Quality Issues: [N found]
1. **[Issue title]** [BLOCKING / ADVISORY]
   - What's wrong: [specific description]
   - Where: [section name]
   - Fix: [specific action to take]

### GDD Alignment: [ALIGNED / GAPS FOUND]
- GDD [name] UI Requirements — [X/Y requirements covered]
- Missing: [list any uncovered GDD requirements]

### Accessibility: [COMPLIANT / GAPS / NON-COMPLIANT]
- Target tier: [tier]
- [list specific accessibility findings]

### Pattern Library: [CONSISTENT / INCONSISTENCIES FOUND]
- [findings]

### Verdict: APPROVED / NEEDS REVISION / MAJOR REVISION NEEDED
**Blocking issues**: [N] — must be resolved before implementation
**Advisory issues**: [N] — recommended but not blocking

[For APPROVED]: This spec is ready for handoff to `/team-ui` Phase 2
(Visual Design).

[For NEEDS REVISION]: Address the [N] blocking issues above, then re-run
`/ux-review`.

[For MAJOR REVISION NEEDED]: The spec has fundamental gaps in [areas].
Recommend returning to `/ux-design` to rework [sections].

Phase 5: Collaborative Protocol

This skill is READ-ONLY — it never edits or writes files. It reports findings only.

After delivering the verdict:

• For APPROVED: suggest running /team-ui to begin implementation coordination
• For NEEDS REVISION: offer to help fix specific gaps ("Would you like me to help draft the missing error state?") — but do not auto-fix; wait for user instruction
• For MAJOR REVISION NEEDED: suggest returning to /ux-design with the specific sections to rework

Never block the user from proceeding — the verdict is advisory. Document risks, present findings, let the user decide whether to proceed despite concerns. A user who chooses to proceed with a NEEDS REVISION spec takes on the documented risk.
