What it costs to keep this loaded
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 | $0.00078 | $0.00600 |
| Opus 5 | $0.00039 | $0.00300 |
| Sonnet 5 | $0.00016 | $0.00120 |
| Haiku 4.5 | $0.00008 | $0.00060 |
Grade A, and why
design-brief-builder 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 yesterday.
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
设计规范技能 (design-brief-builder)
Purpose
把“高级、简洁、现代”等主观表达转成可实施、可验证且有场景理由的视觉与交互规则。
Trigger
- 0→1 产品需要建立视觉或交互规则。
- 产品变更需要新增或改变既有视觉、品牌或交互规则。
- 现有 Product Spec 已足以说明产品目标、用户和核心场景。
恢复既有视觉行为属于维护路线，不重新定义风格。
Required context
- 相关可验收需求，来自现有 Spec、等价文件或用户明确确认。
- 用户、场景、平台和使用环境。
- 用户给出的风格词、品牌线索、截图、参考产品或反例。
- 已有 Design Brief 或设计系统（如果存在）。
Workflow
- 先解释主观词在当前产品语境中的具体含义。
- 存在多种合理方向时，给出 2～3 个差异明确、含理由与代价的候选方向，只追问当前最关键的选择。
- 将选定方向写成“设计意图 → 决策 → 参数 → 理由/代价 → 验证检查点”。
- 只更新本次受影响的视觉、交互与可访问性，不为局部改动重做完整设计。
- 原位更新已有设计规范，标记旧决定替代关系，联动相关需求和活跃任务；不创建重复副本。
Output
- 已确认设计事实、临时假设和待确认项。
- 被选择及被放弃的方向与原因。
- 可执行的设计变量、关键状态和验收检查点。
docs/Design-Brief.md或项目约定的等价文件。
Stop or escalate
- 产品目标或相关行为仍不可验收时补齐需求；已有明确选择时不因缺少同名 Spec 文件阻塞。
- 设计选择会改变产品范围或业务流程：升级为产品变更。
- 参考图未说明喜欢或排斥的具体点：最多追问一个高信息量问题。
- 多个风格要求互相冲突且无法建立临时假设：停止并请求选择。

What ships with it
2 files 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.

design-brief-builder is a skill published in the GitHub repository arctan303/creator.skill (20 stars, last pushed 2d ago), licensed MIT. It adds 78 tokens to every session and 600 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 2026-08-30.
