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 | $0.00030 | $0.03591 |
| Opus 5 | $0.00015 | $0.01795 |
| Sonnet 5 | $0.00006 | $0.00718 |
| Haiku 4.5 | $0.00003 | $0.00359 |
Grade A, and why
ui-design scanned grade A with 1 finding 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
- **macOS / Linux**: `curl -L --fail -o assets/images/logo.png "https://example.com/logo.png"` (add `--create-dirs` if the parent folder doesn't exist; `wget` works too) This is a copy
100% identical to ui-design — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 341 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sibling skills (local only)
Sibling CloudBase skills ship beside this skill. Use local relative paths such as ../auth-tool-cloudbase/SKILL.md.
If a referenced sibling skill file is missing from this environment, ask the user to install the full CloudBase plugin (or the missing skill). Do not HTTP-fetch remote skill or protocol markdown into the agent context.
Activation Contract
Use this first when
- The request is to decide visual direction, produce a design specification, create a prototype, or make layout, typography, color, and visual hierarchy choices for an interface.
- The implementation should follow a deliberate aesthetic rather than directly coding an already-approved design.
Read before writing code if
- The response must choose typography, color, spacing, layout strategy, or other visual rules before code exists.
- The user asks for "design", "prototype", "look and feel", or "style" rather than straight implementation.
Then also read
- Web implementation ->
../web-development/SKILL.md - Mini program implementation ->
../miniprogram-development/SKILL.md
Do NOT use for
- Backend-only tasks, database design, or pure API work without interface output.
- Straight implementation of an already-approved UI without new design decisions.
- Generic frontend coding requests where the visual direction is already settled.
Common mistakes / gotchas
- Writing JSX, WXML, or CSS before outputting the design specification.
- Falling back to generic AI layouts instead of an explicit aesthetic direction.
- Jumping into implementation when the design intent is still unclear.
- Ignoring platform constraints after the visual concept is defined.
Minimal checklist
- Read UI Design Activation Checklist before interface generation.
When to use this skill
Use this skill for frontend UI design and interface creation in any project that requires:
- Creating web pages or interfaces
- Creating mini-program pages or interfaces
- Designing frontend components
- Creating prototypes or interfaces
- Handling styling and visual effects
- Any development task involving user interfaces
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.

ui-design is a skill published in the GitHub repository sutchan/Agent-Skills-Hub (2 stars, last pushed yesterday), licensed MIT. It adds 30 tokens to every session and 3,591 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 100% identical to ui-design, differing in 2 lines, and is treated as a copy.
