design-audit

design-audit is a command for coding agents from fusengine/agents. It costs 37 tokens per session (480 once invoked), scanned A, original, MIT.

A quality check for an existing HTML/CSS design. It checks code-based rules and performs a visual review across themes and screen sizes.

In plain words
What is it for?
Use it to check contrast, fonts, colors, dark mode, interaction states, token use, and visual consistency.
Why use it?
It helps find accessibility, consistency, styling, and responsive-design problems before a design is considered finished.

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-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 yesterday.

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.

What it actually says

/design:audit — Design Quality Audit

Validate an existing design without generating new code.

Complete documentation: skills/design-review/SKILL.md.

Usage

/design:audit ./pages/index.html
/design:audit ./site-1/
/design:audit

When no path is provided, audits all HTML files in the current directory.

Workflow

  1. Identify target files (path argument, or all .html in the current directory).
  2. Read design-system.md if it exists — the reference for token compliance. If missing, audit against skills/design-system/references/typography-pairs.md (forbidden fonts) and contrast-ratios.md (contrast) only.
  3. Run skills/design-review/SKILL.md Part 1 (deterministic checks): contrast, forbidden fonts, color format, em-dash, token adherence, anti-AI-slop, mechanical pre-flight, WCAG, consistency.
  4. Run Part 2 (bounded visual review): serve, screenshot light+dark, cross-viewport, motion verdict if any animation exists.
  5. Report with severity levels: CRITICAL (contrast, missing dark mode, broken accessibility), MAJOR (forbidden fonts, non-OKLCH colors, missing states), MINOR (token mismatches), PASS.

Output Format

| Check     | Status   | Details                                |
|-----------|----------|----------------------------------------|
| Fonts     | FAIL     | Found Inter in header.css:12           |
| Colors    | WARN     | 3 hex values found, convert to oklch() |
| Contrast  | PASS     | All ratios >= 4.5:1                    |
| States    | WARN     | Missing :focus on .btn-secondary       |
| Dark mode | FAIL     | No dark mode implementation found      |

Forbidden

Generating or modifying code (audit only, unless the user explicitly asks for fixes afterward). Skipping any deterministic check. Reporting PASS without actually verifying. Skipping the light+dark screenshot pass.

Changes

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.
