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 | $0.00040 | $0.01100 |
| Opus 5 | $0.00020 | $0.00550 |
| Sonnet 5 | $0.00008 | $0.00220 |
| Haiku 4.5 | $0.00004 | $0.00110 |
Grade A, and why
to-design-brief 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 2d 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
本技能读取两份输入——设计语言文档(含 colors / typography / rounded / spacing / components token 的分析文档,如 DESIGN-linear.md)与 PRD——合成一份 design brief。brief 的读者是 Claude Design 或 OMP 中的设计 agent:它们不应依赖未显式提供的本地上下文,因此 brief 必须自包含,单独交付即可作为后续逐页生成的风格锚点。
输出格式与逐节写法见 BRIEF-FORMAT.md,写作前先完整读取。
输入与决策
- 定位输入文件。 用户未给路径时先在对话上下文中找;找不到再问。设计语言文档通常带 token frontmatter;PRD 通常带需求编号(如
REQ-xx)。两份都要完整读取,不要只读开头。 - 确认设计语言。 同目录存在多份设计语言文档(如
DESIGN-linear.md/DESIGN-stripe.md)且用户未指定时,列出各自气质摘要请用户选择。风格是产品决策,不要代替用户选。 - 确认主题明暗。 设计语言文档多来自营销站分析,其主题(常为深色)不一定适合目标产品。优先级:用户指定 > PRD 约定 > 沿用设计文档原主题并在 brief 顶部标注「沿用原主题,如需反转请告知」。需要反转明暗时,保留色相与气质(强调色、圆角、边框哲学不变),重新推导中性色阶与语义映射。
- 确认输出路径。 用户未指定时写到 PRD 同目录的
design-brief.md;目标文件已存在时先读取,向用户确认覆盖或另存。
合成流程
- 从 PRD 提炼产品骨架:产品定位(一句话说清是什么、不是什么)、端口与最小视口、界面语言、账号/权限体系中影响界面的部分、页面清单。页面清单按 PRD 模块划分,每页标注覆盖的需求编号;纯非功能需求(如数据脱敏)不单列页面,转写为对应页面的设计约束。
- 从设计语言文档转译 token:营销站 token 要转成产品界面可用的两层结构——原始色板 + 语义映射层(背景/文字/边框/状态),brief 中只允许语义层被页面规格引用。原文档缺少后台必需的语义色(成功/警告/危险/信息)时,按原文档色彩气质补齐,并标注哪些是推导新增。字体、圆角、间距、阴影直接沿用原 token,只做取舍不做发明;保留原文档的层次哲学(如「发丝边框优先于阴影」)。
- 推导组件规范:从 token 推导目标产品需要的组件清单(后台类产品通常是:侧边导航、顶栏、按钮组、输入框、表格、状态标签、指标卡、Tabs、面包屑、布局骨架)。每个组件写明引用的语义 token 与关键尺寸,不贴实现代码。
- 写逐页规格:每页列出主区内容结构、用到的组件、关键交互态(空态/加载/错误/权限不足,PRD 有定义才写)。规格描述内容与结构,不重复设计系统里已定的视觉细节。
- 写使用说明与生成顺序:brief 开头写明粘贴用法与逐页指令模板;结尾给出建议出图顺序(先设计系统预览页校准风格,再做骨架页,最后批量出剩余页面)。
校验
发布前逐项确认:
- PRD 中每个需求编号都能在某页规格或设计约束中找到,遗漏的补上;确实不影响界面的,在 brief 末尾注明「不体现于界面」。
- brief 中每个色值、字号、圆角都能追溯到设计语言文档或已标注的推导新增,不存在两处矛盾的取值。
- brief 不引用任何本地文件路径或对话上下文,整段粘贴后信息完整。
- 篇幅控制在一次粘贴可用的范围(正文约 300 行以内);超出时优先压缩逐页规格的重复描述,而不是删减设计系统。
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.

to-design-brief is a skill published in the GitHub repository VoidTechnology/voidtech-claude-plugins (2 stars, last pushed 29d ago), licensed Apache-2.0. It adds 40 tokens to every session and 1,100 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 2026-08-31.
