TrySkills: Skill for Claude Code

.agents/skills/audit/SKILL.md

audit is a skill for Claude Code from ReScienceLab/TrySkills. It costs 54 tokens per session (1,898 once invoked), scanned A, a copy of audit, MIT.

A technical quality audit covering accessibility, performance, themes, responsive layouts, and implementation anti-patterns. It produces a scored report with priorities from P0, most urgent, to P3, lower urgency.

In plain words
What is it for?
Use it when requesting an accessibility check, performance review, responsive-design check, or broader technical quality report.
Why use it?
It turns measurable implementation problems into a prioritised list without 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 ReScienceLab/TrySkills's own configuration. It tells Claude Code how to work on TrySkills 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 TrySkills 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

83% identical to audit — 14 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 — 148 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MANDATORY PREPARATION

Invoke /impeccable — 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 /impeccable teach 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.
