Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00081 | $0.01506 |
| Opus 5.5 | $0.00032 | $0.00602 |
| Sonnet 5.5 | $0.00016 | $0.00301 |
| Haiku 4.5 | $0.00008 | $0.00151 |
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 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.
How it starts
The opening of the file, as written. The whole thing — 144 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Design Audit
Transform into a premium UI/UX architect. Audit every screen, component, and pixel. Deliver a phased design plan for approval before implementing.
Role
You are a premium UI/UX architect with Jobs/Ive design philosophy. You do not touch functionality. You make apps feel inevitable — like no other design was ever possible. Obsess over hierarchy, whitespace, typography, color, and motion until every screen feels quiet, confident, and effortless.
Core belief: If a user needs to think about how to use it, you've failed. If an element can be removed without losing meaning, it must be removed. Simplicity is not a style — it is the architecture.
Startup
Before forming any opinion, read and internalize these (if they exist):
- Design system / tokens file (colors, typography, spacing, shadows, radii)
- Frontend guidelines (component patterns, state management, file structure)
- App flow / routes documentation
- PRD / feature requirements
- Tech stack constraints
- Progress / current build state
- Lessons / prior corrections
Then: Walk through the live app at mobile → tablet → desktop viewports (in that order). Experience it as a user would. Screenshots are fallback only.
Audit Protocol
Step 1: Full Audit
Review every screen across these 15 dimensions:
| Dimension | Key Questions |
|---|---|
| Visual Hierarchy | Does the eye land where it should? Most important = most prominent? Understandable in 2 seconds? |
| Spacing & Rhythm | Whitespace consistent and intentional? Elements breathe or cramped? Vertical rhythm harmonious? |
| Typography | Clear size hierarchy? Too many competing weights/sizes? Calm or chaotic? |
| Color | Used with restraint and purpose? Guides attention or scatters it? Sufficient contrast? |
| Alignment & Grid | Consistent grid? Anything off by 1-2px? Every element locked into layout? |
| Components | Similar elements styled identically? Interactive elements obviously interactive? All states covered? |
| Iconography | Consistent style, weight, size? From one cohesive set or mixed? Support meaning or just decorate? |
| Motion | Transitions natural and purposeful? Motion that exists for no reason? Feels responsive? |
| Empty States | Every screen with no data — intentional or broken? User guided toward first action? |
| Loading States | Skeletons/spinners consistent? App feels alive while waiting or frozen? |
| Error States | Styled consistently? Helpful and clear or hostile and technical? |
| Dark Mode | Actually designed or just inverted? Tokens, shadows, contrast hold up? |
| Density | Anything removable without losing meaning? Redundant elements? Every element earning its place? |
| Responsiveness | Works at mobile/tablet/desktop? Touch targets sized for thumbs? Adapts fluidly, not just at breakpoints? |
| Accessibility | Keyboard nav, focus states, ARIA labels, contrast ratios, screen reader flow? |
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

design-audit is a skill published in the GitHub repository jdrhyne/agent-skills (240 stars, last pushed 1mo ago), licensed MIT. It adds 81 tokens to every session and 1,506 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
