forge-design-impl

forge-design-impl is a skill for Claude Code, Codex from yike-gunshi/forge-skills. It costs 78 tokens per session (2,198 once invoked), scanned A, original, MIT.

A workflow that turns an approved DESIGN.md file into visual code changes while leaving application behavior unchanged. It uses CSS and shared design tokens, which are named values such as colors, spacing, or font sizes.

In plain words
What is it for?
Use it to implement documented visual changes, update styles and layouts, compare real screenshots with the design, and make small, separate commits.
Why use it?
It gives developers a checklist for implementing a design consistently and limits the work to styling and layout. It also requires screenshot and CSS-based checks before completion.

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

forge-design-impl 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 19d 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.

How it starts

The opening of the file, as written. The whole thing — 204 lines — stays where its author put it; the contents beside it link to each section on GitHub.

文档落地路径:遵循 forge-doc-policy 规范。完整白名单 + frontmatter schema 见 ~/.claude/skills/forge-doc-policy/doc-paths.md。 当前文档加载顺序:先读项目 CLAUDE.md、docs/README.md、docs/INDEX.md, 再读 docs/DESIGN.md 当前真相源和相关模块附录;历史 changelog/raw 只在追溯旧决策时读取。 详细规则见 ~/.claude/skills/_shared/current-doc-loading.md。

/forge-design-impl:设计实现

将 DESIGN.md 的设计规范转化为代码。只改样式和布局,不改业务逻辑。

前置条件

  1. DESIGN.md 必须存在且已通过 forge-design 审核(评分 ≥ B)
  2. 如果有 .features/{feature-id}/status.md,确认 design 行为 [✅ 已完成]
  3. 读取 docs/README.md、docs/INDEX.md、docs/DESIGN.md 当前真相源和本次涉及的模块附录,理解设计体系 token、组件规范、页面布局
  4. 如果 .features/{feature-id}/feature-spec.md、DESIGN.md 或模块附录中有 Image 2 / Figma / 视觉稿链接,读取并作为观感参考;实现真相源仍是 DESIGN.md 的 token 和组件规则

流程

读取 DESIGN.md → 识别实现清单 → 逐项实现 → 每项自检 → 原子提交 → 全部完成后质量验证

第1步:识别实现清单

从 DESIGN.md 中提取需要实现的设计变更:

  1. 读取 .features/{feature-id}/status.md / feature spec 中的设计交付项;如需追溯历史,再读 docs/CHANGELOG.md 顶部索引和相关 DESIGN-CHANGELOG.md 条目
  2. 列出具体实现项,每项包含:
    • 变更内容(如"卡片组件圆角从 8px 改为 12px")
    • 涉及文件(定位 CSS/样式文件)
    • 预计改动量(小/中/大)
  3. 向用户展示清单,确认后开始实现
  4. 若存在视觉稿,额外列出:
    • 视觉稿路径
    • 用户确认的关键观感(如信息密度、主次层级、空态情绪)
    • 实现后需要用真实截图对比的页面/状态

第2步:实现设计变更

宿主是 Claude Code 时,样式代码由 Codex 写:调用 codex-delegate,任务书里写明以 DESIGN.md 哪个模块和哪些 token 为准、以下实现原则必须遵守;Claude 截图验收后再走第 3 步提交。宿主是 Codex 时直接写。

实现原则

1. CSS 优先

  • 优先修改 CSS/样式文件,而非组件结构
  • CSS 修改更安全、更可逆
  • 只在布局变更时才改 HTML 结构

2. Token 驱动

  • 所有样式值引用 DESIGN.md 定义的 token
  • 不硬编码颜色值、字号、间距
  • 使用 CSS 变量或 Tailwind 配置中的 token

3. 遵循现有代码风格

  • 不引入新的 CSS 方法论
  • 如果项目用 Tailwind,用 Tailwind;如果用 CSS Modules,用 CSS Modules
  • 不为"更好"而重写不相关的样式

4. 响应式必须

  • 所有变更都要考虑移动端
  • 移动端不是缩小版桌面——要有独立的设计意义
  • 断点处理遵循 DESIGN.md 定义的断点

反 AI 模板编码指导

实现时主动避免以下泛用模式:

排版:

  • 不要所有文本都 text-align: center
  • 标题用 DESIGN.md 指定的字体,不要默认 Inter
  • 行高、字间距遵循设计体系,不用浏览器默认值

配色:

  • 不要用紫色渐变做英雄区背景
  • 不要用彩色圆圈包裹图标
  • 颜色来自 token,不要随意用 Tailwind 调色板

布局:

  • 不要千篇一律的三列等宽网格
  • 不要所有区块等高
  • 留白要有意——不是统一的 py-20
  • 圆角要有层级——按钮小圆角,卡片中圆角,模态大圆角

组件:

  • 不要左边框高亮卡片(border-left: 3px solid accent)
  • 不要用 emoji 做列表图标
  • 不要装饰性浮动色块

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.
