.agents/skills/audit/SKILL.md

audit is a skill for Claude Code from Southclaws/storyden. It costs 31 tokens per session (1,382 once invoked), scanned A, a copy of audit, MPL-2.0.

A structured review of a web interface covering accessibility, speed, visual themes, and behavior on different screen sizes.

In plain words
What is it for?
Use it to check contrast, labels, keyboard navigation, HTML structure, images, animations, layout performance, bundle size, and responsive behavior.
Why use it?
It finds quality problems and ranks them before anyone starts changing the code.

Skill for Claude Code

Written for Claude Code: user-invocable in frontmatter. Also seen: installed under .agents/ (shared by several agents).

This is Southclaws/storyden's own configuration. It tells Claude Code how to work on storyden itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything storyden configures →

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

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 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.

Origin

This is a copy

94% identical to audit — 11 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Run systematic quality checks and generate a comprehensive audit report with prioritized issues and actionable recommendations. Don't fix issues - document them for other commands to address.

First: Use the frontend-design skill for design principles and anti-patterns.

Diagnostic Scan

Run comprehensive checks across multiple dimensions:

  1. Accessibility (A11y) - Check for:

    • Contrast issues: Text contrast ratios < 4.5:1 (or 7:1 for AAA)
    • Missing ARIA: Interactive elements without proper roles, labels, or states
    • Keyboard navigation: Missing focus indicators, illogical tab order, keyboard traps
    • Semantic HTML: Improper heading hierarchy, missing landmarks, divs instead of buttons
    • Alt text: Missing or poor image descriptions
    • Form issues: Inputs without labels, poor error messaging, missing required indicators
  2. Performance - Check for:

    • Layout thrashing: Reading/writing layout properties in loops
    • Expensive animations: Animating layout properties (width, height, top, left) instead of transform/opacity
    • Missing optimization: Images without lazy loading, unoptimized assets, missing will-change
    • Bundle size: Unnecessary imports, unused dependencies
    • Render performance: Unnecessary re-renders, missing memoization
  3. Theming - Check for:

    • Hard-coded colors: Colors not using design tokens
    • Broken dark mode: Missing dark mode variants, poor contrast in dark theme
    • Inconsistent tokens: Using wrong tokens, mixing token types
    • Theme switching issues: Values that don't update on theme change
  4. Responsive Design - Check for:

    • Fixed widths: Hard-coded widths that break on mobile
    • Touch targets: Interactive elements < 44x44px
    • Horizontal scroll: Content overflow on narrow viewports
    • Text scaling: Layouts that break when text size increases
    • Missing breakpoints: No mobile/tablet variants
  5. Anti-Patterns (CRITICAL) - Check against ALL the DON'T guidelines in the frontend-design skill. Look for AI slop tells (AI color palette, gradient text, glassmorphism, hero metrics, card grids, generic fonts) and general design anti-patterns (gray on color, nested cards, bounce easing, redundant copy).

CRITICAL: This is an audit, not a fix. Document issues thoroughly with clear explanations of impact. Use other commands (normalize, optimize, harden, etc.) to fix issues after audit.

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.
