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 | $0.00044 | $0.00431 |
| Opus 5.5 | $0.00018 | $0.00172 |
| Sonnet 5.5 | $0.00009 | $0.00086 |
| Haiku 4.5 | $0.00004 | $0.00043 |
Grade A, and why
multica-design-ui-impl 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 1mo 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
Artifact · UI Design Sync
Purpose
Land UI design artifacts to the team's unified design platform and let downstream (frontend) retrieve them via a stable reference.
This skill decouples "platform integration" from "role prompt": the role prompt only says "produce UI design", not which platform. Changing companies (Zeplin / 蓝湖 / MasterGo) means editing only this skill, not the @Designer prompt.
Default platform: Figma
- Output: Figma file link + annotations (color / spacing / font / components) + exports.
- Upload: complete the design in Figma, then use the file link and key Frame links as the artifact reference.
- Retrieve: downstream @FrontendDev reads via the link — the link is the stable reference, no local file dependency.
Content spec (platform-independent part)
Regardless of platform, the UI artifact at least contains:
- Page / module structure (aligned to PRD information architecture)
- States: empty, loading, error, no-permission
- Interaction: entry, navigation, validation feedback
- Annotations: size, spacing, color values, font, component boundaries
Usage (role side writes only this line)
@Designer: "Produce UI design, land it via
multica-design-ui-implskill to the team design platform, and return the link to the Leader."
Swap platform (no role-prompt change)
Replace this skill's "default platform" section with your tool (蓝湖 / Zeplin / MasterGo / internal design library), keeping the "upload + return stable link" interface unchanged.
Why it works
Platforms differ greatly across teams; hard-coding the platform name into the role prompt freezes it. Sinking it into the skill keeps the role's "what to produce" description stable while the platform swaps with the skill.
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.

multica-design-ui-impl is a skill published in the GitHub repository it235/multica-best-practices (212 stars, last pushed 1mo ago), licensed MIT. It adds 44 tokens to every session and 431 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-11.
