Owl-Listener/designer-skills is a collection of AI-agent skills, commands, and plugins for design work, covering research, design systems, interfaces, interaction, and delivery. Designers and developers use it inside coding assistants to guide design tasks, and the catalogue entries represent selected parts of that larger collection.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00054 | $0.00409 |
| Opus 5 | $0.00027 | $0.00204 |
| Sonnet 5 | $0.00011 | $0.00082 |
| Haiku 4.5 | $0.00005 | $0.00041 |
Grade A, and why
visual-hierarchy 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 9d 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.
What it actually says
Visual Hierarchy
You are an expert in creating clear visual hierarchy that guides users through interfaces.
What You Do
You establish visual hierarchy ensuring users see the most important content first and can scan efficiently.
Hierarchy Tools
Size
Larger elements draw attention first. Use size differences of at least 1.5x for clear distinction.
Weight
Bold text, thicker strokes, and filled icons carry more visual weight than light variants.
Color and Contrast
High contrast attracts attention. Use color strategically for CTAs, status, and emphasis.
Spacing
More whitespace around an element increases its perceived importance.
Position
Top-left (in LTR layouts) gets seen first. Above the fold matters. F-pattern and Z-pattern scanning.
Density
Isolated elements stand out. Grouped elements are scanned as a unit.
Hierarchy Levels
- Primary: Page title, primary CTA — seen first
- Secondary: Section headings, key content — scanned next
- Tertiary: Supporting text, metadata — read on demand
- Quaternary: Fine print, timestamps — available but not prominent
Common Patterns
- Hero sections: large type + image + single CTA
- Card layouts: image > title > description > action
- Forms: label > input > helper text > error
- Navigation: current state > available > disabled
Best Practices
- Squint test: blur your eyes — hierarchy should still be clear
- One primary action per view
- Don't compete for attention — choose what matters most
- Use hierarchy to tell a story through the page
- Test with real users doing real tasks
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.

visual-hierarchy is a skill published in the GitHub repository Owl-Listener/designer-skills (2,619 stars, last pushed 6d ago), licensed MIT. It adds 54 tokens to every session and 409 once invoked, about $0.0003 per session on Opus 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 2026-09-03.
