The 37signals Way

Lean, opinionated product development from Getting Real to Shape Up

Build lean, opinionated products using the 37signals philosophy from Getting Real, Rework, and Shape Up. This skill equips your AI agent with the principles behind Basecamp's approach — shaping work with appetite instead of estimates, betting on six-week cycles, running small autonomous teams, and treating deliberate omission as a competitive advantage.

What your agent learns

Build Less

Competitive advantage through deliberate omission — fewer features maintained indefinitely, underdo the competition instead of outdo them.

Shaping the Work

Define work that is rough, solved, and bounded before assigning it to a team. Use breadboarding and fat marker sketches. Set appetite, not estimates.

Betting & Cycles

Six-week fixed cycles with a circuit breaker — if it doesn't ship, it doesn't get an automatic extension. Two-week cool-downs between cycles. Abolish backlogs.

Small Teams

Three-person autonomous units (1 designer, 1–2 programmers) with full authority over implementation. Track progress with hill charts, not standups.

Opinionated Software

Ship with strong defaults over endless preferences. Write clear, honest copy. Say no to most feature requests and let the product reflect a clear point of view.
