What it does
Preview Md is an agent skill from 312362115/claude. MD 文件浏览器预览：GitHub 风格渲染 + 左侧自动目录。 在完成方案设计（specs）或开发计划（plans）的 MD 文件后触发。 询问用户是否要在浏览器中打开预览，确认后执行。 触发词：方案写完、计划写完、review MD、预览文档。 工作流位置：task-start 方案产出后 / 任意 MD 文档完成后
Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts (for example `CHANGELOG.md`, `scripts/md-notify.sh` and `scripts/md-preview.py`).
It works with GitHub. The licence is MIT.
Example prompts
- “/preview-md”
Requirements
- Python 3
- Node.js
- A Bash shell
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 2d4fa49. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 3 files in scripts/ (Shell, Python and JavaScript), which the agent can run.
Shell commands in SKILL.md call:
node
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Preview Md loads about 636 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 178 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

MD 文件浏览器预览
写完方案/计划等需要 review 的 MD 文件后，用浏览器打开 GitHub 风格预览。
触发条件
当你（Claude）完成以下类型的 MD 文件创建或大幅修改时，必须触发此 skill：
- 方案设计文档（
docs/specs/**/*.md） - 开发计划文档（
docs/plans/**/*.md） - 用户明确要求预览的任何 MD 文件
不可跳过原则：满足上述触发条件时，必须执行 Step 1 询问用户是否预览。Claude 不得以任何理由（如"纯后端文档"、"内容简单"、"不涉及 UI"等）自行判断跳过。是否预览由用户决定，不由 Claude 决定。
不触发 的场景：
- 非
.md文件：HTML、JSON、YAML 等其他格式文件不走此 skill（HTML 原型直接用open命令打开） - memory 文件、CLAUDE.md、README.md 等非 review 类文件
- 对 MD 文件的小幅修改（如修错别字、更新状态标记）
执行流程
Step 1: 询问用户
MD 文件写完后，向用户提问：
文件已创建：<文件路径>
要在浏览器中打开预览吗？Step 2: 用户确认后打开预览
用户确认后，执行：
node ~/.claude/skills/preview-md/scripts/preview-md.mjs <md-file-absolute-path>Step 3: 等待反馈
预览打开后，等待用户 review 反馈，根据反馈修改文档内容。
注意事项
- 脚本位置在
~/.claude/skills/preview-md/scripts/preview-md.mjs - 脚本会生成临时 HTML 文件并用默认浏览器打开
- 渲染特性：GitHub Markdown CSS + 左侧固定目录（h1-h4）+ 滚动高亮 + 平滑跳转
扩展语法：terminal / flow 代码块
preview-md 在标准 Markdown 之上提供两种轻量图示代码块，专为"不想调 diagram skill 但又想比纯文字更有画面感"的场景设计。生产端（writing / deep-research 等）应按本节约定输出。
```terminal — 终端窗口
展示命令行操作、CLI 输出、安装/启动步骤时使用。渲染为 macOS 风格的终端窗口（红黄绿圆点 + 标题栏）。
何时用：
- 展示一段命令执行（单条或多条）
- 展示命令的输出示例
- 开发指南/快速开始中的 setup 步骤
何时别用：
- 单条命令且没有特殊格式 → 用普通
```bash即可 - 纯代码片段（非 shell 语境）→ 用对应语言的代码块
语法：首行可选 $ title 作为窗口标题，其余为内容。
```terminal
$ 快速开始
npm install
npm run dev
# 服务启动在 http://localhost:3000
``````flow — 轻量流程图
展示流程、决策树、步骤串联时使用。比调 diagram skill 更快、更贴近正文，适合简单到中等复杂度的线性/分叉流程。
何时用：
- 方案中的"执行步骤"示意
- 决策树（含
？/?的节点自动高亮为决策样式） - 工作流阶段串联
何时别用：
- 复杂的多分叉合流、有向图 → 调 diagram skill 画真正的流程图
- 时序交互（多角色）→ 调 diagram skill 画时序图
语法：
| 形态 | 写法 | 渲染 |
|---|---|---|
| 竖向主干 | 每行一个节点，↓ 单独一行作为连接符 | 主干 pill 居中列，↓ 对齐主干 |
| 横向流 | 一行内用 → 分隔多个节点 | 平铺横向 pill 链 |
| 横竖混合 | 主干竖向，某一行内嵌 → 分支 | 主干走中间列，分支向右延伸 |
| 决策节点 | 节点文本含 ？ 或 ? | 黄底带边框 pill |
| 注释 | 节点后追加 （xxx） | 灰色注释文字挂在节点右侧 |
示例：
```flow
task-manager
↓
task-start（对焦 + 方案）
↓
task-execute → 编码 → 调试
↓
需求完成？→ task-finish → 标 done
```设计原则：
- flow 块中不要写长句，每个节点控制在 10 字内，超长的信息放正文说明
→扩展只用于挂 1-3 个分支节点；再多就该拆成多行或改调 diagram- 一个 flow 块表达一个完整小流程，别把多个无关流程塞进同一个块
