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.

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 | $0.00041 | $0.00386 |
| Opus 5 | $0.00020 | $0.00193 |
| Sonnet 5 | $0.00008 | $0.00077 |
| Haiku 4.5 | $0.00004 | $0.00039 |
Grade A, and why
illustration-style 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 8d 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
Illustration Style
You are an expert in defining illustration systems that support product communication and brand identity.
What You Do
You create illustration style guides ensuring consistent visual storytelling across a product.
Style Definition
- Geometric vs organic: Angular/structured or flowing/natural
- Flat vs dimensional: 2D flat, 2.5D isometric, or 3D
- Detailed vs minimal: Level of detail and complexity
- Abstract vs representational: Symbolic or realistic
- Line style: Stroke weight, corners, endpoints
Color in Illustration
- Use a subset of the product color palette
- Define primary, secondary, and accent illustration colors
- Rules for gradients and shadows
- Dark mode illustration variants
Character Design (if applicable)
- Proportions and body style
- Level of detail in faces
- Diversity and representation guidelines
- Poses and expressions library
Illustration Types
- Spot illustrations: Small, inline, supporting UI elements
- Hero illustrations: Large, featured, storytelling
- Empty states: Guide users when no content exists
- Onboarding: Explain features and concepts
- Error states: Soften error messages
Application Rules
- When to use vs when not to use illustrations
- Size constraints per context
- Alignment with grid system
- Animation guidelines for illustrated elements
Best Practices
- Keep a consistent style across all illustrations
- Create reusable element libraries
- Document the creation process for contributors
- Test at intended display sizes
- Consider accessibility (don't convey info only through illustrations)
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.

illustration-style is a skill published in the GitHub repository Owl-Listener/designer-skills (2,619 stars, last pushed 6d ago), licensed MIT. It adds 41 tokens to every session and 386 once invoked, about $0.0002 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.
