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 | $0.00047 | $0.01722 |
| Opus 5 | $0.00023 | $0.00861 |
| Sonnet 5 | $0.00009 | $0.00344 |
| Haiku 4.5 | $0.00005 | $0.00172 |
Grade A, and why
frontend-design 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 10d 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.
The source is not reproduced here
A licence we could not identify
The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.
What ships with it
8 files 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.

frontend-design is a skill published in the GitHub repository holaboss-ai/holaOS (11,191 stars, last pushed 20d ago), with no licence file. It adds 47 tokens to every session and 1,722 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.
Other skills, from other repositories
accessibility
A guide for designing and checking digital interfaces so people using screen readers, keyboards, or switch controls can use them. It follows WCAG 2.2 Level AA, a common accessibility standard.
figma
Complete guide for the Figma plugin — REST API access, real-time selection monitoring via CDP, and the figma-app interactive UI. Read this IMMEDIATELY when the user asks to work with Figma.
frontend
Two-mode frontend skill: (1) authoring — accessibility, responsive layout, loading/error states, performance, DESIGN.md authoring, visual direction; (2) critique — READ-only scored review of built UI against anchored rubric, AI-slop detection, two isolated assessments. Router invokes mode via context.
design-critique
Pre-emit self-critique for UI/visual/design output (components, CSS, copy, layouts) — anti-slop gates, taste dials, and a design-token contract check, run BEFORE the work is shown, not after. Use whenever producing or editing anything with a visual/UX surface.
design-experience
Build distinctive production-grade app and web interfaces. Use for UI/UX, responsive states, accessibility, visual systems, redesigns, or frontend polish.
motion
Injects high-craft UI motion, spring physics, tactile micro-interactions, page transitions, and staggered animations into components and prototypes.
