技术文档更新

该 Skill 是一套用于更新 Next.js 项目文档的引导式工作流，核心作用是帮助你根据源代码的变更，来分析、更新和创建相关的文档，确保代码和文档保持同步。它特别为审查 Pull Request (PR) 时的文档完整性检查而设计，通过一系列标准化的步骤来规范文档的修改过程。 This skill should be used when the user asks to "update documentation for my changes", "check docs for this PR", "what docs need updating", "sync docs with code", "scaffold docs for this feature", "document this feature", "review docs completeness", "add docs for this change", "what documentation is affected", "docs impact", or mentions "docs/", "docs/01-app", "docs/02-pages", "MDX", "documentation update", "API reference", ".mdx files". Provides guided workflow for updating Next.js documentation based on code changes.
