核心观点#

文章需要先给出判断，再展开依据，避免只做资料堆叠。
每个关键结论都应说明原因、适用边界和可能的反例。
如果涉及新闻、产品、模型版本或价格等会变化的信息，正文应附带 Markdown 来源链接。

建议结构#

模块	写作目标
背景	解释问题来源和读者为什么需要关心
分析	拆解关键机制、案例或对比对象
实践	给出可执行步骤、检查清单或决策建议
局限	标注不确定性、风险和后续观察点

实践建议#

正式文章应优先使用二级标题组织主体内容，并在每个章节下写出完整段落。如果主题偏技术，应补充实现路径、依赖条件和常见误区；如果主题偏产品，应补充用户场景、竞品对比和可衡量指标。

风险与局限#

兜底草稿无法替代模型生成，也不会主动搜索外部来源。在发布前，应确认事实是否准确、来源是否充分、frontmatter 摘要是否和正文一致。

总结#

当前草稿提供了可发布文章的骨架。恢复 LLM 后，应重新生成完整正文，让文章具备更高信息密度、更多事实依据和更好的 Markdown 阅读体验。
