+# Citation Verification Scripts
+
+## 状态说明
+
+**这些脚本是参考实现，不是主要工作流的一部分。**
+
+本目录中的Python脚本提供了基于API的引用验证实现，但**实际的引用验证工作流使用WebSearch和Google Scholar**，而不是这些脚本。
+
+## 为什么保留这些脚本？
+
+这些脚本作为**参考实现**保留，用于：
+
+1. **理解验证逻辑** - 展示引用验证的完整逻辑和步骤
+2. **学习API使用** - 了解如何使用CrossRef、arXiv、Semantic Scholar等API
+3. **高级用例** - 对于需要批量验证或自动化的场景，可以参考这些实现
+
+## 主要工作流
+
+**实际的引用验证应该使用 `ml-paper-writing` skill 中的 Citation Workflow：**
+
+1. 使用 WebSearch 查找论文
+2. 在 Google Scholar 上验证
+3. 从 Google Scholar 获取 BibTeX
+4. 验证声明（如需要）
+5. 添加到 bibliography
+
+详见 `ml-paper-writing` skill 的 "Citation Workflow (Hallucination Prevention)" 部分。
+
+## 脚本说明
+
+### verify-citations.py
+
+完整的引用验证脚本，包含：
+- 四层验证机制（格式、存在性、信息匹配、内容验证）
+- 多API支持（CrossRef、arXiv、Semantic Scholar）
+- 报告生成
+
+**用途**: 参考实现，了解完整的验证逻辑
+
+### api-clients.py
+
+API客户端库，包含：
+- CrossRefClient - DOI验证
+- ArXivClient - arXiv论文验证
+- SemanticScholarClient - 通用学术搜索
+- CitationAPIManager - 统一API管理
+
+**用途**: 参考实现，了解如何使用学术API
+
+### format-checker.py
+
+BibTeX和LaTeX格式检查工具，包含：
+- BibTeX格式验证
+- LaTeX引用检查
+- 格式错误报告
+
+**用途**: 参考实现，了解格式检查逻辑
+
+## 使用建议
+
+**对于日常论文写作**:
+- ✅ 使用 `ml-paper-writing` skill 的 Citation Workflow
+- ✅ 使用 WebSearch 和 Google Scholar
+- ❌ 不要使用这些Python脚本
+
+**对于批量验证或自动化**:
+- 可以参考这些脚本的实现
+- 根据需要修改和使用
+- 注意API速率限制
+
+## 依赖安装
+
+如果需要运行这些脚本（仅用于参考或高级用例）：
+
+```bash
+pip install bibtexparser requests semanticscholar arxiv
+```
+
+## 更多信息
+
+详见 `citation-verification` skill 的 SKILL.md 文件。

+BibTeX and LaTeX Format Checker
+
+独立的格式检查工具,用于验证 BibTeX 和 LaTeX 引用格式。
+
+功能:
+1. BibTeX 格式检查 - 验证条目结构、必填字段、字段格式
+2. LaTeX 引用检查 - 提取引用、检查一致性
+3. 快速格式验证 - 无需 API 调用的快速检查
+
+使用方法:
+    python format-checker.py references.bib
+    python format-checker.py paper.tex --check-latex
