What is design-audit?

A structured review of a website, web app, landing page, or frontend that scores its design and lists evidence-based issues and fixes.

Checking layout, visual hierarchy, user experience, mobile behavior, accessibility, perceived performance, wording, and frontend polish.

It turns a broad visual or usability review into clear priorities instead of a list of subjective comments.

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	$0.00107	$0.02728
Opus 5	$0.00053	$0.01364
Sonnet 5	$0.00021	$0.00546
Haiku 4.5	$0.00011	$0.00273

Security

Grade A, and why

design-audit 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 8d 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 Audit

Overview

Use this skill to inspect a website or frontend surface and produce a practical design audit: evidence, scores, concrete issues, and prioritized fixes. Prefer direct inspection of the running page whenever possible.

Use re-audit mode when the user asks to compare before/after, check improvements, re-run the audit after fixes, or verify whether a previous audit's issues were solved.

Language

Match the user's language for the entire audit. Support English and Italian explicitly.

If the user writes in Italian, write headings, table labels, statuses, priorities, verdicts, category notes, and fix sections in Italian.
If the user writes in English, write the audit in English.
If the user mixes languages, use the dominant language of the request.
Keep preset IDs unchanged (landing-page, saas-dashboard, etc.) so prompts and comparisons remain stable.
Keep standard frontend terms in English when they are clearer or commonly used: CTA, focus state, keyboard navigation, layout shift, responsive, mock, hero, dashboard.

Italian label mapping:

Overall -> Sintesi
Scorecard -> Griglia
Category Notes -> Note per Categoria
Top Issues -> Problemi Principali
Recommended Fixes -> Fix Consigliati
Quick wins -> Fix Veloci
Medium work -> Interventi Medi
Deeper work -> Interventi Strutturali
Re-Audit -> Rivalutazione
Score Delta -> Delta Punteggi
Fix Verification -> Verifica Fix
Verification notes -> Note di Verifica
Remaining Priorities -> Priorità Rimaste
Next Fix Pass -> Prossimo Giro di Fix
What works -> Cosa funziona
What hurts -> Cosa penalizza
Fix -> Fix
Priority -> Priorità
Confidence -> Confidenza
Verdict -> Verdetto
Excellent -> Eccellente
Good -> Buono
Needs work -> Da migliorare
Weak -> Debole
Critical -> Critico
High -> Alta
Medium -> Media
Low -> Bassa
Fixed -> Risolto
Improved -> Migliorato
Still open -> Ancora aperto
Regressed -> Peggiorato

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.
