The 37signals Way

Build lean, opinionated products — less process, more shipping.

Part of Book skills by @wondelai

Applies the philosophy from Rework, Getting Real, and Shape Up: build lean, opinionated products and cut the busywork.

What it does

  • Cuts scope and process down to what ships.
  • Brings Rework / Shape Up thinking to how you build.

  1. 1Download the .zip and unzip it — you’ll get a folder called 37signals-way.
  2. 2In the Claude app: open Settings → Capabilities → Skills, choose Add / Upload, and select the folder (or the .zip).
  3. 3In Claude Code: drop the folder into your project’s .claude/skills/ directory, then type /skills to confirm it loaded.
  4. 4That’s it — the skill activates on its own when it fits what you’re doing.
