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 | $0.00085 | $0.01889 |
| Opus 5 | $0.00043 | $0.00945 |
| Sonnet 5 | $0.00017 | $0.00378 |
| Haiku 4.5 | $0.00009 | $0.00189 |
Grade A, and why
html-demo 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 4d 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.

仿真型 HTML 交互 demo
服务「demo 先行」工作流:先出可交互 demo 多轮快速迭代、拍板交互细节,再写 PRD(prd-writer「demo 先行变体」)。
与 prd-writer S5 的「展示型原型」(PRD 写完后生成、功能模块平铺、截图导向,规范见
prd-writer/html-prototype.md)是两种形态,按场景选用:迭代敲定交互 → 本 skill;为已定稿 PRD 配图 → 展示型。
Workflow
Step 1: 输入确认 —— 用户截图(复刻基准,缺则先要)+ 需求一句话
Step 2: 生成 v1 —— 自包含单文件落 tmp/{需求名}-交互方案.html,写完提示用户打开预览
Step 3: 多轮迭代 —— 就地修改唯一一份,每轮改完提示刷新查看;不另存副本、不留版本文件
Step 4: 拍板归档 —— demo 复制到对应需求 prototypes/(删除 tmp/ 原件避免双源);
需要正式 PRD 时衔接 prd-writer「demo 先行变体」(交互细节从 demo 代码提取)
(按需)Step 5: 关键状态截图 —— 调 screenshot skill 归档 assets/,PRD 嵌图
页面调试确认(默认不开浏览器,按判断树决定)
默认口径:写完直接交付,提示用户刷新查看,由用户人工验收——不开浏览器(实战沉淀:常规控件盲改命中率足够高,起浏览器的时间成本大于收益)。
仅以下三种情况开 Claude in Chrome 实时核对:
| # | 触发 |
|---|---|
| 1 | 用户明确要求看效果,或提出视觉问题("太丑" / "对不齐" / "显示不对")——此时必须看着调,不盲改 |
| 2 | demo 含自定义视觉形态:图表 / 矩阵热力图 / 时间轴、动效与过渡、复杂布局(多列网格、自适应宽度、浮层定位、拖拽) |
| 3 | 高保真复刻截图是本次交付重点 |
明确不开(无论首版还是迭代):常规表单控件(输入框 / 下拉 / radio / checkbox / 开关 / 按钮 / 普通表格列表)、文案替换、选项增删与排序、默认值调整、删除已有内容。简单需求的首版 demo 同样不开。
开了之后的操作纪律:
- 后台跑
python -m http.server <port> --directory "tmp"→ 扩展navigate到http://localhost:<port>/{需求名}-交互方案.html(中文文件名需 URL 编码)→ 之后computer screenshot/read_page/javascript_tool均正常 - 关键坑:Claude in Chrome 扩展无法操作
file://本地页面(navigate / screenshot / read_page 全被拒,报 "browser-internal or unparseable URLs"),必须走http://localhost - server 起一次保持到 demo 拍板,不每轮起停
- 核对用
javascript_tool直接设状态再截图,不用computer点击——扩展的点击 / 滚动会误触发页面事件改乱 demo 状态(实证:选中项莫名跳变,白排查一轮) - 兜底:扩展未安装 / 用户不用 Chrome / 无浏览器权限 / 连接失败时,优雅回退到「写完提示用户打开预览、每轮改完提示刷新查看」,由用户截图 / 口头反馈——用户自查路径始终保留为 fallback
质量规范(生成与迭代)
- 自包含单文件:一个 HTML 内联全部 CSS/JS(CDN 可选);落
tmp/唯一一份就地迭代 - 复刻真实:以用户提供的截图为准复刻目标系统的布局与视觉;假数据贴近真实业务(真实风格的文案 / 标签值 / 数据形态)。项目级视觉口径(主题色参考等)由项目 local rule 定义
- 全状态可达:每个状态(成功 / 失败 / 空 / 加载中 / 禁用)必须能通过界面操作到达——为不易自然触发的状态提供模拟开关(如「模拟失败」toggle、空态切换),不允许存在"改代码才能看到"的状态
- mock 标注:演示性假设(能力映射、概率模拟等)集中为顶部常量 + 注释「演示用,实际以 {真实来源} 为准」,防止评审者当真
- 代码组织利于反向提取(衔接 prd-writer demo 先行变体(S3 交互细节提取)):状态机集中管理、配置常量化、关键交互规则带注释——写 PRD 时直接从代码读取状态、文案、禁用与显隐逻辑,不靠回忆对话
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.
- 4d ago First seen · 78 lines · 85 tokens per session scan A e009b04045c9
html-demo is a skill published in the GitHub repository ryanzhao1011/workframe (4 stars, last pushed 17d ago), licensed MIT. It adds 85 tokens to every session and 1,889 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.
