The app was Symvibe, a paid Mac board for running coding agents side by side. I used REA, a reverse-engineering skill for Claude Code, to turn its behaviour into a spec, and let Claude Code build from there. Thirteen days and 58 commits later there was vibeboard, a free, open-source alternative to Symvibe, which costs $19 a month, with none of its code in it. What I learned along the way: most of the engineering came from the model, but I still steered every day, mostly on edge cases and CI the launch videos were the surprise: /brag did a great job, it drove the real app, framed the shots, wrote the music, and fixed its own jerky cuts once I pointed them out rebuilding a product's behaviour from the outside is now cheap, so the code alone protects less, and respecting licences and the original authors matters more The video shows a plan, build, review team passing one job along, with the builder asking before it edits a file. vibeboard: https://github.com/ricca200xx/vibeboard Symvibe: https://www.symvibe.com REA: https://github.com/morluto/rea /brag: https://github.com/latent-spaces/brag If you want to use it, go ahead, and if you find issues, open them on GitHub. I'm genuinely happy to share this.   submitted by   /u/Internal-Trouble-631 [link]   [comments]
