      • 用 OpenSpec，AI 动手前会先交计划给你审。 第 1 步：在项目目录初始化。 第 2 步：输入 /opsx:propose 加功能名，AI 生成提案和任务清单。 第 3 步：审完输入 /opsx:apply 开始实现，再 /opsx:archive 归档。 免费开源。 地址：

      • 让 AI 助手直接写代码 最怕它需求没吃透就瞎写 看下 Fission-AI/OpenSpec 它把 Spec-driven development 搬到了 AI 编程里 先定好规范和规格说明 再让 AI 照着这个框架去干活 省得每次花半天对齐上下文 最后改出来的代码还是东一榔头西一棒子

      • 让 agent 直接写代码，改完没人知道当初要什么？ OpenSpec 是 Spec 驱动开发框架，需求先写成 Markdown 规格再动手，每改动一个文件夹，含 proposal、规格、任务。 适合已有项目改造的人，规格别写太死，留迭代口子。 你先写规格，还是先写代码？ #Spec驱动 #AI编程 @grok

      • AI 写码老跑偏？先把规格对齐再动手。 OpenSpec 给 Cursor / Claude Code / Codex 这类助手加一层轻量规格：先 propose 出改动提案和规格任务清单，你审过再 apply。规格就是普通 Markdown。官网文档写明对接 30+ 工具，不锁某一个 IDE。 装法：curl -fsSL | sh，进项目 openspec init。MIT 开源本体…

      • 给 Vibe Coding 配一份「施工说明书」📝 OpenSpec 让 AI 先把需求、设计和任务清单写成 Markdown，你审阅后再让它写代码。 每次变更单独整理，完成后归档并更新规范。后续接手、复盘，都有文档可查。 支持 Claude Code、Codex、Cursor，MIT 开源。

      • 让 AI 写代码最气人的不是写错，是写了一堆对的东西但方向不对。7.1 万颗星的 OpenSpec 把「先定规格再实现」变成流程。 动手前多花十分钟写规格，可能省掉三轮返工。
