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 | $0.00120 | $0.04048 |
| Opus 5 | $0.00060 | $0.02024 |
| Sonnet 5 | $0.00024 | $0.00810 |
| Haiku 4.5 | $0.00012 | $0.00405 |
Grade A, and why
figma-ios-vertical-layout-safearea 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.

Figma 垂直布局与安全区识别规范
版本: v2.1 最后更新: 2026-04-20
⛔ 红线规则(最高优先级)
1. 禁止用宽度比例 scale 缩放垂直方向
// ❌ 严重错误:把宽度比例用在 y / height
let scale = /* host.utils.screen_width */ / 375.0
view.snp.makeConstraints { make in
make.top.equalTo(...).offset(49 * scale) // ❌
make.height.equalTo(111 * scale) // ❌
make.bottom.equalToSuperview().offset(-34 * scale) // ❌
}
垂直方向只允许以下三种写法:
| 场景 | 写法 |
|---|---|
| 相对相邻元素的固定 gap | make.top.equalTo(prev.snp.bottom).offset(figma_gap) |
| 相对 safeArea | make.bottom.equalTo(view.safeAreaLayoutGuide.snp.bottom).offset(-figma_gap) |
| 元素本身的 height/width | make.height.equalTo(figma_h)(直接用 Figma 实测值,不乘 scale) |
理由:scale = 屏宽 / 375 仅反映横向像素缩放。如果把它用在 y / height,iPhone SE(375)和 iPhone 16 Pro Max(430)会产生 ~14% 的纵向偏差,严重时按钮会被吃掉、内容跑出 safeArea。设计稿的 y / height 是固定 pt,不应随屏宽缩放。
2. 禁止把 safeArea.top 当导航栏底
如果设计稿没有原生导航栏(直接是吸顶卡片),用 view.safeAreaLayoutGuide.snp.top 即可;如果有导航栏,用 host.json → utils.status_bar_nav_height 的表达式,不要混用。
3. 禁止凭空给容器加 padding/margin
任何 offset 都要能从 Figma frame.absolute / frame.relative 推出来,禁止"看着别扭加 12pt"。如果数据不对,先回 design.json 找根因,不要在代码里加补丁。
4. Scroll 容器的顶/底必须锚定邻居,禁止硬编码 y/height ⭐️
如果页面上存在 _role.is_sticky_top / is_sticky_bottom 节点(见 audit.json.sticky_keyword_hits,关键字:吸顶 / 吸底 / sticky_top / sticky_bottom),它们之间的 scroll 承载区必须把顶/底约束到这些 sticky 节点上:
// ❌ 错误:scroll 容器用绝对 y/height(已在 341:313 '垂直滚动' 事故中出现)
formScrollView.snp.makeConstraints { make in
make.top.equalToSuperview().offset(195)
make.height.equalTo(407) // iPhone 8 上直接盖掉底部吸底按钮
}
// ✅ 正确:顶对 sticky_top.bottom,底对 sticky_bottom.top
formScrollView.snp.makeConstraints { make in
make.leading.trailing.equalToSuperview()
make.top.equalTo(stepStripContainer.snp.bottom).offset(figma_gap_top)
make.bottom.equalTo(bottomBarContainer.snp.top).offset(-figma_gap_bottom)
}
判定依据:audit.json 里 sticky_keyword_hits[].sibling_rule 会明确列出本规则。

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.

figma-ios-vertical-layout-safearea is a skill published in the GitHub repository mythkiven/figma-ios-codegen (9 stars, last pushed 2mo ago), licensed MIT. It adds 120 tokens to every session and 4,048 once invoked, about $0.0006 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 2026-08-31.

figma-codegen
Generate framework-aware code from a Figma design. Reads the project's stack profile and emits code matching the existing framework (React/Vue/Svelte/Next/etc.) and styling (Tailwind/CSS/CSS-in-JS), reusing existing components and design tokens instead of regenerating from scratch. Triggers whenever the user wants a…
figma-build
Build a Figma design from code or a description — the reverse of figma-codegen. Reuses the connected file's existing design system (components, variables, styles) instead of drawing primitives with hardcoded values. Triggers whenever the user wants something created or updated IN Figma from code or a spec — e.g.…

Use SwiftUI scene/window modifiers first; switch to macos-appkit-bridge only when SwiftUI cannot express the behavior.
