aesthetic-foundations

aesthetic-foundations is a skill for Claude Code, Codex from caoxg/claude-skill-aesthetic-foundations. It costs 200 tokens per session (1,030 once invoked), scanned A, original, MIT.

A visual-design review guide drawing on painting, photography, graphic design, and Eastern visual traditions. It gives structured ways to judge layout, color, typography, spacing, and visual hierarchy.

In plain words
What is it for?
Use it when reviewing an interface, screenshot, typography choice, color scheme, layout, or other visual decision. It helps produce a short list of concrete design improvements.
Why use it?
It helps replace vague design feedback with specific observations and changes. It also checks whether a design still works in grayscale, at a glance, and with less content.

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.

Fable 5.1 $0.00200 $0.01030
Opus 5.5 $0.00080 $0.00412

Security

Grade A, and why

aesthetic-foundations 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 2mo 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

Aesthetic Foundations

这个 skill 在你接到视觉判断任务时, 先把审美词汇激活, 然后再开始评审或建议. 没有它的话默认会滑回"通用 web 风格": 圆角、Material 阴影、彩虹色 badge — 那不是审美, 那是肌肉记忆.

触发后第一件事

别立刻给答案. 先做一次 critique-protocol 7 步走:

  1. 三秒第一印象 — 眼睛先落在哪?
  2. 眯眼测试 — 层次还在吗?
  3. 灰度测试 — 转黑白还能不能用?
  4. 留白测试 — 空白是"意味" 还是"没填满"?
  5. 裁剪测试 — 能砍掉什么?
  6. 大师参照 — 哪条原则被违反 / 被尊重?
  7. 改动清单 — 3-5 个具体动作, 不要"再干净一点"

详见 critique-protocol.md.

加载哪些 reference (按主题)

任务 必看
布局 / 构图 references/composition.md + references/grid-and-rhythm.md
色彩 references/color.md
字体 / 排印 references/typography.md
信息层级 references/visual-hierarchy.md
空 / 留白 references/ma-and-negative-space.md

加载哪些 master (按情境)

情境 看谁
光与窗 / 单光源场景 Vermeer (painters.md)
平衡 + 非对称 Mondrian, Bada Shanren (painters.md / 中式审美.md)
用色块情绪 Rothko (painters.md)
决定性瞬间 / 几何瞬间 布列松 (photographers.md)
隔离主体 / 极简肖像 Avedon (photographers.md)
工业克制 / 功能美 Dieter Rams (designers.md)
网格 + 极少字体 Vignelli (designers.md)
留白 / 东方极简 原研哉 + 中式审美.md
中式语境 / 项目用中文 masters/中式审美.md 优先于 Bauhaus

不变量 (别忘了)

  • 审美不是规则集 — 是张力. 三分法 vs 居中, 网格 vs 破格, 都对, 看情境.
  • 先看后说 — 任何"建议"前必须先描述眼睛实际看到的 (眼动 / 焦点 / 层次), 不要直接跳到 "建议把 padding 加到 16px".
  • 不要逃进 hex — "把 ink3 改成 ink2" 是 token 操作, 不是设计判断. 判断是: "这里需要更弱的灰让标题更突出".
  • 数量级而非数值 — "留白翻倍" 比 "padding 24→48" 更靠近设计语言. 像素是结果, 不是输入.
  • 不与 frontend-design 抢活 — 那个 skill 管"web UI 是否符合工程规范". 这个 skill 管"为什么这样组合好看".

What ships with it

11 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.

Changes

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.
