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

markdown_everything CLAUDE.md 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 1mo 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.

项目概述

markdown-everything 是一个 AI Agent Skill,将 20+ 种文档格式(PDF、Word、Excel、PPT、图片、音频)转换为 Markdown。核心依赖是 markitdown,针对中文 PDF 做了 pdfplumber 的 Unicode 字符级提取来解决乱码。

常用命令

# 基本转换
python SKILL/markdown-everything/scripts/convert_document.py "文档.pdf" -o "输出.md"

# 直接用 markitdown CLI
markitdown "文档.docx" -o "输出.md"

# JSON 格式输出
python SKILL/markdown-everything/scripts/convert_document.py "文档.docx" --json-output

# 详细日志
python SKILL/markdown-everything/scripts/convert_document.py "文档.docx" --verbose

# 环境管理(PowerShell)
.\SKILL\markdown-everything\scripts\manage_environment.ps1 -Command setup
.\SKILL\markdown-everything\scripts\manage_environment.ps1 -Command check

# 环境管理(Bash)
bash SKILL/markdown-everything/scripts/manage_environment.sh setup
bash SKILL/markdown-everything/scripts/manage_environment.sh check

架构

├── SKILL.md                          # Skill 定义,Claude Code 加载此文件触发转换
└── scripts/
    ├── convert_document.py           # 主入口:DocumentConverter 类 + CLI

    ├── manage_environment.ps1        # Windows 环境管理(Conda/pip)
    └── manage_environment.sh         # Linux/macOS 环境管理

转换流程

  1. PDF 文件 → PDFEncodingFixer.convert() → pdfplumber Unicode 字符级提取
  2. 如果 pdfplumber 失败 → 回退到 page.extract_text()
  3. 如果仍然失败 → 回退到标准 markitdown
  4. 非 PDF 文件 → 直接用 DocumentConverter.convert() 调 markitdown
  5. 可选:LLM 后处理(GPT-4 / Claude)

关键类

  • DocumentConverter (convert_document.py): 封装 markitdown,管理 LLM 客户端初始化,返回 {success, text_content, output_file} 结构
  • PDFEncodingFixer (pdf_encoding_fixer.py): 用 pdfplumber 的 page.chars 对象按 Unicode 字段提取文字,绕过 PDF 字节编码问题。包含文本质量检测(中文比例、乱码率)

环境管理脚本

PowerShell 和 Bash 版本功能一致:

  • 自动检测 Conda 安装路径(扫描多个默认位置)
  • 自动创建 markitdown Conda 环境
  • 支持 pip 镜像源(tsinghua/aliyun/douban)
  • 支持 MARKITDOWN_USE_PIP=true 跳过 Conda 直接用系统 Python

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.
