从零开始动手实现 Claude Code

该项目是讲解如何从零构建类似 **Claude Code** 的 AI Agent 工具，
共计 12 节课，每节课都有一个可运行的 Python 文件。

内容从最基础的 Agent 循环，逐步叠加工具调用、任务规划、
子智能体、上下文压缩、多智能体协作和自主执行等功能，
最终构建出一个完整的 AI Agent 系统。

https://gitcode.com/GitHub_Trending/an/learn-claude-code/blob/main/docs/zh/s04-subagent.md

只使用bash工具，以及skill，就可以自主完成代码开发，错误调试，依赖包的安装等，最终生成pdf文件。

Follow these workflows:\n\n## Reading PDFs\n\n**Option 1: Quick text extraction (preferred)**\n```bash\n# Using pdftotext (poppler-utils)\npdftotext input.pdf -  # Output to stdout\npdftotext input.pdf output.txt  # Output to file\n\n# If pdftotext not available, try:\npython3 -c "\nimport fitz  # PyMuPDF\ndoc = fitz.open(\'input.pdf\')\nfor page in doc:\n    print(page.get_text())\n"\n```\n\n**Option 2: Page-by-page with metadata**\n```python\nimport fitz  # pip install pymupdf\n\ndoc = fitz.open("input.pdf")\nprint(f"Pages: {len(doc)}")\nprint(f"Metadata: {doc.metadata}")\n\nfor i, page in enumerate(doc):\n    text = page.get_text()\n    print(f"--- Page {i+1} ---")\n    print(text)\n```\n\n## Creating PDFs\n\n**Option 1: From Markdown (recommended)**\n```bash\n# Using pandoc\npandoc input.md -o output.pdf\n\n# With custom styling\npandoc input.md -o output.pdf --pdf-engine=xelatex -V geometry:margin=1in\n```\n\n**Option 2: Programmatically**\n```python\nfrom reportlab.lib.pagesizes import letter\nfrom reportlab.pdfgen import canvas\n\nc = canvas.Canvas("output.pdf", pagesize=letter)\nc.drawString(100, 750, "Hello, PDF!")\nc.save()\n```\n\n**Option 3: From HTML**\n```bash\n# Using wkhtmltopdf\nwkhtmltopdf input.html output.pdf\n\n# Or with Python\npython3 -c "\nimport pdfkit\npdfkit.from_file(\'input.html\', \'output.pdf\')\n"\n```\n\n## Merging PDFs\n\n```python\nimport fitz\n\nresult = fitz.open()\nfor pdf_path in ["file1.pdf", "file2.pdf", "file3.pdf"]:\n    doc = fitz.open(pdf_path)\n    result.insert_pdf(doc)\nresult.save("merged.pdf")\n```\n\n## Splitting PDFs\n\n```python\nimport fitz\n\ndoc = fitz.open("input.pdf")\nfor i in range(len(doc)):\n    single = fitz.open()\n    single.insert_pdf(doc, from_page=i, to_page=i)\n    single.save(f"page_{i+1}.pdf")\n```\n\n## Key Libraries\n\n| Task | Library | Install |\n|------|---------|---------|\n| Read/Write/Merge | PyMuPDF | `pip install pymupdf` |\n| Create from scratch | ReportLab | `pip install reportlab` |\n| HTML to PDF | pdfkit | `pip install pdfkit` + wkhtmltopdf |\n| Text extraction | pdftotext | `brew install poppler` / `apt install poppler-utils` |\n\n## Best Practices\n\n1. **Always check if tools are installed** before using them\n2. **Handle encoding issues** - PDFs may contain various character encodings\n3. **Large PDFs**: Process page by page to avoid memory issues\n4. **OCR for scanned PDFs**: Use `pytesseract` if text extraction returns empty\n</skill>'}]},
