Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00016 | $0.00924 |
| Opus 5.5 | $0.00006 | $0.00370 |
| Sonnet 5.5 | $0.00003 | $0.00185 |
| Haiku 4.5 | $0.00002 | $0.00092 |
Grade A, and why
frontend-quality-auditor 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 1mo 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 — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Frontend Quality Auditor
Use this skill to decide whether a frontend is ready to ship and what should be fixed first.
Core Contract
Produce a concise, evidence-based quality report. Do not redesign the product unless the user explicitly asks for fixes. The default output is an audit, not a rebuild.
Audit Workflow
- Identify the project type, framework, entry routes, styling system, scripts, and available preview or deployment URL.
- Inspect source structure first, then inspect rendered output when a browser or screenshot workflow is available.
- Review desktop and mobile breakpoints before judging visual quality.
- Check the launch-critical surfaces: hero or first screen, navigation, primary CTA, forms, media, interactive states, footer, error/loading/empty states, and any checkout, booking, pricing, or dashboard flows.
- Classify issues by severity:
- Blocker: likely broken, inaccessible, misleading, unusable, or launch-damaging.
- High: visibly unprofessional, confusing, slow, fragile, or trust-reducing.
- Medium: polish, consistency, or resilience issue worth fixing soon.
- Low: minor refinement that should not block launch.
- Recommend the smallest useful next action for each meaningful issue.
- End with a clear Ship, Ship after fixes, or Do not ship yet judgment.
Review Areas
- Visual polish: hierarchy, spacing, typography, alignment, density, color, contrast, icon use, media treatment, empty space, and generic AI-looking patterns.
- Responsive behavior: mobile composition, tablet layout, overflow, touch targets, nav behavior, media crops, and text wrapping.
- Accessibility: semantic structure, headings, labels, focus states, keyboard paths, alt text, contrast, reduced motion, ARIA misuse, and modal/menu behavior.
- Performance: image and video weight, layout shift risk, font loading, animation cost, bundle hints, third-party scripts, and Core Web Vitals concerns.
- SEO and sharing basics: title, description, canonical, Open Graph, heading order, crawlable content, image alt text, sitemap/robots signals when relevant.
- Interaction quality: hover, focus, active, disabled, loading, error, success, offline, retry, and empty states.
- Content and trust: vague claims, placeholder copy, weak CTAs, unsupported proof, unclear pricing or contact flows, missing legal or support signals where expected.
What ships with it
2 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.

frontend-quality-auditor is a skill published in the GitHub repository TheGoat395/Codex-Skills (134 stars, last pushed 6d ago), licensed MIT. It adds 16 tokens to every session and 924 once invoked, about $0.0001 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 2026-08-30.
