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.

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 | $0.00039 | $0.00663 |
| Opus 5 | $0.00019 | $0.00331 |
| Sonnet 5 | $0.00008 | $0.00133 |
| Haiku 4.5 | $0.00004 | $0.00066 |
Grade A, and why
design-systems 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 12d 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 — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Design Systems
Help the user build and scale design systems using frameworks from 4 product leaders who have built design systems at companies like Figma and Airbnb.
How to Help
When the user asks for help with design systems:
- Assess the need - Determine if they need consistency, speed, or both, and whether they're at the right stage for a design system
- Define the scope - Clarify whether they need a component library, design tokens, documentation, or all three
- Design for adoption - Help them make the system easy enough that non-designers can use it correctly
- Plan for evolution - Guide them on how to maintain and evolve the system over time
Core Principles
Separate concept from production
Bob Baxley: "Once we locked down on the block frames, we could send it to an agency and they could do the full high-res comps in a day, because they knew exactly what they were doing." Use low-fidelity 'block brain diagrams' to lock down conceptual logic, then apply the design system for rapid high-fidelity output.
Design systems drive enterprise expansion
Claire Butler: "Design systems are one of the main reasons you upgrade from pro to org or enterprise. That became just the key thing we leaned in on." Design systems practitioners are key internal champions for organizational scaling.
Assets should teach their own usage
Jessica Hische: "My goal always when designing a logo is to design a logo that's so easy to use that you don't have to be an extremely skilled designer to design well with it." Design assets that 'teach' the user how to apply them through their inherent structure, prioritizing ease of use over complexity.
Flat design is evolving
Brian Chesky: "I think flat design is over or ending. We're going to move back into a world with color, texture, dimensionality, more haptic feedback." Interface design is shifting from flat aesthetics to more dimensional, tactile, and AI-enhanced experiences.
Questions to Help Users
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-systems is a skill published in the GitHub repository cnfeat/top-pm-skills (48 stars, last pushed 3mo ago), licensed MIT. It adds 39 tokens to every session and 663 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 2026-08-30.
