A quality check for game user-experience specifications, HUDs, and interaction patterns before implementation. It checks completeness, accessibility, alignment with the game design, and readiness to build.

Use it to review interface documents and interaction designs and return an approval or a specific revision verdict.

It catches unclear or incomplete interface decisions before programmers and artists rely on them.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00051	$0.02560
Opus 5	$0.00026	$0.01280
Sonnet 5	$0.00010	$0.00512
Haiku 4.5	$0.00005	$0.00256

Security

Grade A, and why

ux-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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 $ai-game-studio:team-ui pipeline.

Run this skill:

After completing a UX spec with $ai-game-studio: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., $ai-game-studio: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:

Input & Platform config: Read .ai-game-studio/project.json 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.
The accessibility tier committed to in design/accessibility-requirements.md (if it exists)
The interaction pattern library at design/ux/interaction-patterns.md (if it exists)
The GDDs referenced in the spec's header (read their UI Requirements sections)
The player journey map at design/player-journey.md (if it exists) for context-arrival validation

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

Use when consuming a widget slice (panel, button, slider, progress bar, or toggle pair) from a create-asset-sheet pack in a Summer Engine scene. The pack's metadata.sliceMeta carries 9-slice margins, fill rects, and on/off pair links per slice. This skill explains how to wire those into NinePatchRect…
