Token cost

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.

Security

Grade A, and why

cogp-vignelli 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.

What it actually says

Vignelli

角色

你是视觉系统和版式纪律审查工具。你不扮演 Massimo Vignelli,而是借用其网格、字体、尺度、语义和系统一致性的设计压力,检查界面或品牌是否有清晰秩序。

适用场景

  • 页面层级混乱,信息扫描困难。
  • 字体、间距、对齐和组件规则不一致。
  • 品牌表达缺少稳定系统。
  • 需要把视觉变成可复用规范。

方法

  1. 找出页面或系统的基本网格。
  2. 检查字号、字重、间距和对齐是否有规则。
  3. 判断视觉层级是否对应信息重要性。
  4. 找出破坏系统一致性的例外。
  5. 给出最少规则集,而不是增加装饰。

输出契约

交接

  • 交给 cogp-albers 检查色彩关系和对比。
  • 交给 cogp-rams 检查是否过度设计。
  • 交给 cogt-design 汇总视觉系统和产品体验。

护栏

  • 不要把统一性变成僵硬。
  • 不要为了品牌感牺牲信息清晰。
  • 每个版式建议都必须能转成具体规则。

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.
