  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • 4 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by staruhub on GitHub. Read the source before you install it.

Installation

Install the Mineru Pdf Parser AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/staruhub/ClaudeSkills/tree/main/skills/Geek-skills-mineru-pdf-parser
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/staruhub/ClaudeSkills.git /tmp/ClaudeSkills
mkdir -p .claude/skills
cp -r /tmp/ClaudeSkills/skills/Geek-skills-mineru-pdf-parser .claude/skills/mineru-pdf-parser
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Mineru Pdf Parser in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Mineru Pdf Parser on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Mineru Pdf Parser is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

MinerU PDF Parser

将复杂PDF文档转换为机器可读的Markdown/JSON格式,适用于LLM和RAG应用。

安装

bash
# 推荐使用uv安装
pip install uv
uv pip install -U "mineru[all]"

# 下载模型(首次使用)
mineru-models-download

快速使用

命令行

bash
# 解析单个PDF
mineru -p input.pdf -o output_dir

# 批量解析
mineru -p pdf_folder/ -o output_dir

# 指定解析模式
mineru -p input.pdf -o output_dir --backend vlm      # VLM模式(高精度)
mineru -p input.pdf -o output_dir --backend pipeline # Pipeline模式(快速)
mineru -p input.pdf -o output_dir --backend hybrid   # 混合模式(平衡)

Python API

python
from mineru import MinerU

mineru = MinerU()
result = mineru.parse("document.pdf")

# 获取输出
markdown = result.to_markdown()
json_data = result.to_json()

详细API见 references/api_reference.md

解析模式选择

模式特点适用场景
pipeline快速、资源少简单文档、纯文本PDF
vlm高精度、复杂布局学术论文、公式表格文档
hybrid平衡速度精度通用场景

输出文件

  • {filename}.md - Markdown正文
  • {filename}_content_list.json - 结构化JSON
  • images/ - 提取的图像
  • {filename}_middle.json - 中间结果(调试)

格式详情见 references/output_formats.md

最佳实践

学术论文

bash
mineru -p paper.pdf -o output --backend vlm

批量处理

python
from mineru import MinerU
import os

mineru = MinerU(backend="hybrid")
for pdf in os.listdir("pdfs/"):
    if pdf.endswith(".pdf"):
        result = mineru.parse(f"pdfs/{pdf}")
        result.save(f"output/{pdf[:-4]}/")

RAG数据准备

python
sections = result.get_sections()
for section in sections:
    vector_db.add(section.title, section.content)

启用GPU加速

修改 ~/.mineru.json 中 device-mode 为 cuda。

更多见 references/best_practices.md

验收标准(解析任务完成前自查)

  • 输出目录里 .md 与 _content_list.json 都存在,把实际路径回报用户
  • 抽查 1-2 页对照原 PDF:表格/公式没有明显丢失或错乱;有问题主动告知而不是静默交付
  • backend 选择有依据(简单文本→pipeline;公式表格密集→vlm;拿不准→hybrid)
  • 批量任务报告成功/失败清单,失败的给原因

已知陷阱

陷阱具体表现应对
首次运行缺模型未执行 mineru-models-download 直接解析报错安装后先跑模型下载;下载体积大,提前告知用户耗时
无 GPU 硬跑 vlmCPU 上 vlm 模式极慢,像卡死无 GPU 时用 pipeline/hybrid;有 GPU 改 ~/.mineru.json 的 device-mode 为 cuda
扫描件预期过高低清晰度扫描 PDF 解析质量差提前告知扫描件效果取决于清晰度;结果差时换 backend 重试一次,仍差则如实报告
大文件内存压力数百页 PDF 单次解析内存暴涨大文件分批解析或按章节拆分

脚本

使用 scripts/mineru_parse.py 进行解析,支持错误处理和日志记录。

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Mineru Pdf Parser AI skill do?

用 MinerU 将复杂PDF文档转换为LLM友好的Markdown/JSON格式。适用于:(1) PDF转Markdown/JSON,(2) 提取PDF中的文本、表格、公式、图像,(3) 解析学术论文、技术文档、商业报告,(4) 为RAG应用准备文档数据,(5) 批量处理PDF。触发关键词:"PDF解析"、"PDF转Markdown"、"提取PDF表格/公式"、"MinerU"、"parse PDF"等。不用于:PDF的阅读/填表/签名/拆分合并(用宿主pdf工具)、Word/PPT等非PDF格式解析、只需读几页内容的场景(直接读即可,不必转换)。

Why use Mineru Pdf Parser on TypingMind?

Because you install it once and use it with any model. Mineru Pdf Parser is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Mineru Pdf Parser in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/staruhub/ClaudeSkills/tree/main/skills/Geek-skills-mineru-pdf-parser. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Mineru Pdf Parser?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Mineru Pdf Parser?

As many as you like. As long as a model supports skills, you can use Mineru Pdf Parser with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Mineru Pdf Parser AI skill free?

Yes. It is published on GitHub by staruhub under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
