Traction scoreGitHub stars can be faked, so popularity alone can be misleading. Traction Score looks for broader signs of real attention, adoption, and active maintenance.
This skill library distills the Rails conventions used at 37signals—from Campfire, Fizzy, and DHH’s own reviews—into a set of agent-ready skills. It covers architecture, naming, security, Hotwire, migrations, jobs, testing, and webhooks, giving Rails developers a default baseline for writing and reviewing code the way 37signals does. Tech leads can use it to standardize team practices without writing internal docs from scratch.
