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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00043 | $0.04946 |
| Opus 5.5 | $0.00017 | $0.01978 |
| Sonnet 5.5 | $0.00009 | $0.00989 |
| Haiku 4.5 | $0.00004 | $0.00495 |
Grade A, and why
design-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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 401 lines — stays where its author put it; the contents beside it link to each section on GitHub.

When to use
Render-verification gate. A UI verdict is gated on the design-artifact verification checklist: where render capability exists, do not pass a design task without render evidence (checklist steps 1–5); where it is absent, scope the verdict to what was statically checked and say so — never "looks good" without evidence.
Use this skill when:
- Reviewing pull requests with UI changes
- Auditing frontend components for design quality
- Verifying responsive design across viewports
- Checking accessibility compliance (WCAG 2.1 AA)
- Testing interaction flows and user experience
- Conducting visual QA on new features
Do NOT use when:
- Creating new designs (use
fe-designskill instead) - Reviewing backend/API code only
- Quick syntax checks (use linters)
Prerequisites
One of the following browser automation tools:
- Playwright MCP (recommended) — browser automation, screenshots, viewport testing
- Chrome DevTools — screenshot capture, performance analysis
A live preview URL is required for testing.
Procedure: Design review
- Inspect the PR and preview — Read the PR description, diff, and identify changed components/pages; read the probe artifact and run the appearance floor over the preview URL (Phase 0).
- Walk the interactions — Run Phase 1; cover hover/focus/active/disabled, keyboard, loading, and form error states.
- Cover responsiveness, polish, a11y, robustness — Run Phases 2–5 in order; record findings per phase.
- Audit code-health and content — Run Phases 6–7; check tokens, dead styles, copy, console warnings.
- Verify and report — Consolidate findings in the report structure; classify each as Blocker / High / Medium / Nit before posting.
Phase 0: Preparation
- Read PR description and git diff.
- Identify changed components and affected pages.
- Navigate to preview URL.
- Read the probe artifact
agents/runtime/state/ui-conformance.json(ui_conformance_probe --target <file> --reference <file>) — its per-dimension counters are the behavioral evidence Phases 1–2 report against. Absent is absent, never clean; a dimension the host could not exercise carries a not-applicable row with its reason rather than a zero. - Run the appearance floor (§ Appearance verification) — mandatory on every review.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-review is a skill published in the GitHub repository event4u-app/agent-config (19 stars, last pushed yesterday), licensed MIT. It adds 43 tokens to every session and 4,946 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-03.
