AutomationIntermediate★ 2,246⑂ 228AI score 8/10Last updated: Sep 10, 2026

What it does

Gives Claude the full 37signals (Basecamp) product playbook.

  • Scores 0–10 any product plan, feature scope, or team process and lists the exact changes needed to reach 10/10
  • Five pillars: ①Build less ②Shaping (problem, appetite, solution, rabbit holes, no-gos) ③Betting table with six-week cycles + two-week cool-downs ④Three-person teams and hill charts ⑤Opinionated software and honest UI copy
  • A common mistakes table and an 8-question diagnostic that pinpoints process problems fast
  • Deep dives live in the bundled references/ files (shaping, betting, execution, UX copy, case studies)

Who it's for

  • Founders and PMs whose roadmaps and backlogs keep growing while ship dates slip
  • Small dev teams wanting to drop standups, story points and status meetings
  • Product owners who say yes to every request and now maintain a bloated product
  • Solo devs who need a ruthless v1 scope cut

Examples

  1. "Here's our quarterly roadmap — score it the 37signals way and rewrite it as six-week bets" → score plus 3–4 shaped pitches
  2. "Shape the 'invite a teammate' feature" → five-element pitch with breadboard, rabbit holes and no-gos
  3. "Draft a reply declining this feature request" → an honest "not right now" with no false promises
