aghub: Skill for Claude Code

.agents/skills/audit/SKILL.md

audit is a skill for Claude Code from AkaraChen/aghub. It costs 54 tokens per session (1,932 once invoked), scanned A, a copy of audit, MIT.

A technical review tool for checking a website or application for accessibility, speed, responsive behaviour, theming issues, and common implementation mistakes. It produces a scored report with severity levels and suggested actions.

In plain words
What is it for?
Use it to audit an existing frontend, assess accessibility and performance, find responsive or theme-related issues, and create a prioritised list of problems to fix.
Why use it?
It helps identify measurable quality problems before someone else has to find them. The instructions specify checks such as keyboard access, colour contrast, image descriptions, and form labels.

Skill for Claude Code

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

This is AkaraChen/aghub's own configuration. It tells Claude Code how to work on aghub 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 aghub 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 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.

Origin

This is a copy

86% identical to audit — 34 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 — 158 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MANDATORY PREPARATION

Invoke /frontend-design — it contains design principles, anti-patterns, and the Context Gathering Protocol. Follow the protocol before proceeding — if no design context exists yet, you MUST run /teach-impeccable first.


Run systematic technical quality checks and generate a comprehensive report. Don't fix issues — document them for other commands to address.

This is a code-level audit, not a design critique. Check what's measurable and verifiable in the implementation.

Diagnostic Scan

Run comprehensive checks across 5 dimensions. Score each dimension 0-4 using the criteria below.

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

Score 0-4: 0=Inaccessible (fails WCAG A), 1=Major gaps (few ARIA labels, no keyboard nav), 2=Partial (some a11y effort, significant gaps), 3=Good (WCAG AA mostly met, minor gaps), 4=Excellent (WCAG AA fully met, approaches AAA)

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

Score 0-4: 0=Severe issues (layout thrash, unoptimized everything), 1=Major problems (no lazy loading, expensive animations), 2=Partial (some optimization, gaps remain), 3=Good (mostly optimized, minor improvements possible), 4=Excellent (fast, lean, well-optimized)

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.
