文档版本对比
核心文件类型
- llms.txtA standardized file format that allows website owners to communicate AI training and usage policies to AI crawlers, language models, and AI-driven search engines.:索引文件,包含链接和简要内容描述。LLM或代理需要跟随这些链接才能获取详细信息。
- llms-full.txtA complete document file containing all detailed content in a single file without requiring additional navigation.:完整文档文件,将所有详细内容直接包含在单个文件中,无需额外导航。

关键差异与选择建议
llms.txtA standardized file format that allows website owners to communicate AI training and usage policies to AI crawlers, language models, and AI-driven search engines. vs llms-full.txtA complete document file containing all detailed content in a single file without requiring additional navigation.
llms.txtA standardized file format that allows website owners to communicate AI training and usage policies to AI crawlers, language models, and AI-driven search engines.的优势:
- 文件体积小,适合所有LLM的上下文窗口
- 作为索引文件,提供结构化导航
- 减少不必要的上下文占用
llms-full.txtA complete document file containing all detailed content in a single file without requiring additional navigation.的考量:
- 包含完整文档内容,无需额外请求
- 对于大型文档库,文件可能过大(LangGraphA framework within the LangChain ecosystem for building stateful, multi-actor applications with language models.版本通常包含数十万tokens)
- 可能超出大多数LLM的上下文窗口限制
实践应用指南
重要提醒:代码审查必不可少
即使LLM能够访问最新的文档,当前最先进的模型也不总是能生成完全正确的代码。请始终将AI生成的代码视为起点,在部署到生产环境前务必进行人工审查。
通过MCP服务器使用llms.txtA standardized file format that allows website owners to communicate AI training and usage policies to AI crawlers, language models, and AI-driven search engines.
截至2025年3月9日,主流IDE尚未原生支持llms.txtA standardized file format that allows website owners to communicate AI training and usage policies to AI crawlers, language models, and AI-driven search engines.格式。但您可以通过MCP服务器有效利用这一格式:
🚀 推荐使用mcpdocAn MCP server provided by LangChain for integrating llms.txt documentation into LLMs and IDEs.服务器
LangChainA framework for developing applications powered by language models through composable components.官方提供了专门为LLM和IDE服务的MCP服务器:
👉 langchain-ai/mcpdoc GitHub仓库
该MCP服务器支持将llms.txtA standardized file format that allows website owners to communicate AI training and usage policies to AI crawlers, language models, and AI-driven search engines.集成到以下工具中:
- Cursor
- Windsurf
- Claude
- Claude Code
📘 详细的设置说明和使用示例可在仓库中找到。
高效使用llms-full.txtA complete document file containing all detailed content in a single file without requiring additional navigation.的策略
在支持IDE中(如Cursor、Windsurf):
- 将llms-full.txtA complete document file containing all detailed content in a single file without requiring additional navigation.添加为自定义文档
- IDE会自动对内容进行分块和索引
- 实现检索增强生成(RAG)策略
无IDE支持时:
- 使用具有大上下文窗口的聊天模型
- 手动实现RAG策略来管理和查询文档
- 考虑文档分块和向量化存储
技术展望
llms.txtA standardized file format that allows website owners to communicate AI training and usage policies to AI crawlers, language models, and AI-driven search engines.格式代表了AI编程工具标准化的重要一步。随着更多开发工具原生支持这一格式,AI辅助编程的效率和准确性将得到显著提升。这种格式不仅适用于LangChainA framework for developing applications powered by language models through composable components.生态系统,也为其他AI编程框架提供了可借鉴的文档标准化方案。
