design-qa

design-qa is a skill for Claude Code, Codex from DKeken/codex-skills-alternative. It costs 103 tokens per session (919 once invoked), scanned A, original, MIT.

A review of a built prototype against its approved mockup, specification, or requirements.

In plain words
What is it for?
Use it to check screens and states such as loading, empty, error, and success against a known design reference.
Why use it?
It finds differences in layout, spacing, typography, colors, states, and behavior before the prototype is shared or handed to developers.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is prototype: http://localhost:5173 source: ./mocks/onboarding.png + context.md.

Good fit Use it to check screens and states such as loading, empty, error, and success against a known design reference.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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.

Security

Grade A, and why

design-qa 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 9d 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.

Design — Design QA

Verify the built prototype actually matches the intended design + requirements. Catch drift before it ships. Unlike design-audit (open-ended critique of any UI), QA is a conformance check against a known source of truth — it answers "does this match what we agreed to build?"

When to use

  • A prototype is built and you need to confirm it matches the mockup/spec before review.
  • Final gate before design-share or dev handoff.
  • "Does it match the design?", "conformance check".

When NOT to use

  • No spec/reference to compare against → that's open critique → design-audit.
  • Nothing built yet → build it first.

Inputs

  • The built prototype (local URL or path).
  • The source of truth: reference image/mockup, ./design/context.md, ./design/ideate/*.
  • Acceptance/success criteria (from context).

Workflow

  1. Capture the implementation via a browser-automation tool — screenshots of key screens and states (loading/empty/error/success).
  2. Visual conformance — compare to the reference: layout, type scale, spacing rhythm, palette, radii/shadows, iconography. Note every drift with the expected vs actual value.
  3. Behavioral conformance — walk the flow: do interactions, states, and navigation match the intended UX?
  4. Requirements conformance — does it satisfy the goal + success criteria from context? Any scope item missing?
  5. Accessibility sanity — contrast, focus order, target size, keyboard reachability (flag what needs manual AT testing — automated checks aren't full WCAG).
  6. Write ./design/qa.md: PASS items + prioritized fix list (severity × effort) + a verdict.

Output: ./design/qa.md

prototype: http://localhost:5173   source: ./mocks/onboarding.png + context.md
visual:
 ✓ layout matches  ✗ body type 14px (spec 16px)  ✗ accent #7C3 (spec #6366F1)
behavior:
 ✓ happy path  ✗ no error state on empty name (spec requires inline error)
requirements (vs success criteria):
 ✓ 3-step wizard  ✓ progress saved  ✗ missing "skip" affordance (scope v1)
a11y:
 ✗ CTA contrast 3.1:1 (<4.5)   manual: screen-reader pass still required
verdict: NOT READY — 4 fixes (2 HIGH: error state, contrast). Loop to design-prototype.

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.

design-qa is a skill published in the GitHub repository DKeken/codex-skills-alternative (15 stars, last pushed 3mo ago), licensed MIT. It adds 103 tokens to every session and 919 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
