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 | $0.00075 | $0.01279 |
| Opus 5 | $0.00037 | $0.00639 |
| Sonnet 5 | $0.00015 | $0.00256 |
| Haiku 4.5 | $0.00007 | $0.00128 |
Grade A, and why
briefbound-design-system 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 7d 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.

Briefbound Design System
目标
建立或修正跨组件可复用的设计契约,让 token、组件 API、variants、主题和设计工具映射拥有清楚的事实源与渐进迁移路径。只治理已证明是系统级的问题,不借设计系统之名重写全部 UI。
Briefbound task contract
- Context Boundary: 受影响产品 surface、现有 token/主题/组件库、组件消费者、Storybook 或文档、Figma 资源、构建发布方式和迁移约束。
- Output Contract: 最小系统契约、事实源选择、兼容迁移、受影响组件或 token 实现,以及消费者和视觉验证证据。
- Allowed Action: 在授权范围内修改共享 token、主题、组件、文档/Storybook、映射和必要测试;不顺带重新设计产品页面或改变无关业务行为。
- Success Evidence: token/类型/组件测试、代表性消费者验证、主题和 variants 状态检查、浏览器截图或 Figma/code 映射证据,以及迁移兼容性结果。
- Stop Condition: 品牌或产品方向未定、事实源所有权冲突、破坏性迁移缺少授权、消费者范围不可界定,或设计工具权限/环境阻止关键验证。
- Route Out: 产品交互方向转
briefbound-ui-design;品牌与视觉语言转briefbound-visual-design;独立页面实现 handoff 转briefbound-frontend-engineering;系统审查转briefbound-ui-review;真实外部库决策转briefbound-feature-reuse-research;验证后的真实残留转briefbound-development-cleanup;阻塞回briefbound-router。
统一调用契约
- 只处理 Briefbound task contract 范围;先证明问题跨越多个消费者或共享契约,单点问题返回当前页面 owner。
- 用户可见内容默认中文,只报告系统决策、迁移影响、证据和剩余风险;代码、命令、路径、错误原文、API/协议、skill 名和枚举保留原样;Route Out 仅以 Briefbound task contract 为准,末行写
下一步建议: <一个具体动作>。
系统闸门
满足至少一项才进入本 owner:
- 同一语义在多个组件或页面出现漂移、重复或硬编码。
- token、主题、组件 API、variants 或状态契约需要新增或迁移。
- Figma variables/components 与代码 token/components 缺少稳定映射。
- 共享组件的改变需要兼容多个消费者、版本或发布边界。
只有“想统一一下”“代码不够整齐”不足以触发。先在现有系统中寻找已有 primitive、token 和组件 API,避免平行事实源。
系统 owner 负责新契约及为证明迁移有效所需的代表性消费者,不把每个消费者机械转交 Frontend Engineering。只有剩余工作已经变成独立产品页面实现、拥有不同边界或需要跨会话交接时才 Route Out;同一迁移的浏览器证据只运行一次。
事实源与契约
- 明确每类事实源:基础值、semantic token、组件 token、组件 API、设计资产和文档分别由哪里拥有。
- token 使用语义名称表达用途,不把具体颜色或尺寸伪装成语义;主题只替换值,不改变业务含义。
- component variants 表达稳定、有限的产品差异;临时页面组合不升级为全局 variant。
- 组件 API 优先语义 props、组合和原生行为,避免布尔参数爆炸、样式逃生口成为默认路径。
- 状态至少考虑 default、hover、focus、active、disabled、loading、error 和选中态,但只实现组件真实支持的集合。
- Figma/code 映射复用现有 Variables、Styles、Components 和 Code Connect 能力;没有 Figma 环境时不伪造同步证据。
渐进迁移
- 盘点事实源、消费者和重复定义,锁定最小迁移单元与兼容要求。
- 先建立新契约及验证,再迁移代表性消费者;不要一次替换全仓。
- 兼容层必须有明确消费者、退出条件和删除时机,避免永久双轨。
- 按依赖顺序迁移其余消费者,机械变更可批量执行,但每类至少验证一个代表实例。
- 只有消费者清零且发布/回滚边界允许时才删除旧 token、API 或组件。
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.

briefbound-design-system is a skill published in the GitHub repository CCDawn/codex-skills (4 stars, last pushed 25d ago), licensed MIT. It adds 75 tokens to every session and 1,279 once invoked, about $0.0004 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.
