# 我为 REA 做了一个开源伴侣，把逆向工程发现转化为构建计划

一篇 Reddit 帖子发布了 REA Reconstruction Companion，这是一个采用 MIT 许可证、面向 AI 编码代理的技能，与 REA（Reverse Engineer Anything）配合使用，将逆向工程发现转化为功能拆解、需求、架构以及分阶段的构建/测试计划，并为 Claude Code 和 Codex 提供安装程序。

## Description

作者介绍了一个 REA 的伴侣技能，它接收 REA 的调查输出并将其转化为规范和路线图：功能拆解、需求、架构以及分阶段的构建与测试计划，可用于整个应用、单个功能或单个函数的范围。它将观察到的行为与假设分开保存，把需求链接到测试，并可选择性地捕获性能测量数据。核心是 MIT 许可下的纯 Markdown，包含面向 Claude Code 和 Codex 的安装程序，以及供其他代理使用的自定义技能目录；REA 需单独安装，一个可选规则可在 REA 工作期间自动加载该伴侣。帖子请求对工作流程提供反馈，但 GitHub 仓库链接并未以可用 URL 的形式给出。

## Original README

I built REA Reconstruction Companion with help from AI. I wanted a better way to get from “how does this app work?” to “what would it take to build something similar?” It’s a skill for AI coding agents, used alongside REA (Reverse Engineer Anything) . REA handles the investigation. The companion helps turn those findings into a feature breakdown, requirements, architecture, and a plan you can build and test in stages. You can use it on a whole app, one feature, or a single function. For example: Use REA on this app so I can build a similar local tool. Start with a specification and roadmap. If you later ask the agent to implement it, the skill guides that work too. It keeps observed behavior separate from assumptions, links requirements to tests, and includes performance measurements where they matter. The core is plain Markdown and MIT licensed. There’s an installer for Claude Code and Codex, plus support for other agents through a custom skills directory. REA is installed separately. You can also enable an optional rule that tells the agent to load the companion during relevant REA work, or leave that off and invoke it yourself. GitHub: REA Reconstruction Companion The README has setup instructions and a prompt you can give your agent to handle installation. I’d be interested in feedback on the workflow, especially anything it misses when rebuilding a smaller feature or function.   submitted by   /u/Electrical_Worth7942   to   r/coolgithubprojects [link]   [comments]
