Build lean, opinionated products using the 37signals philosophy from "Getting Real", "Rework", and "Shape Up". Use when the user mentions "Getting Real", "Rework", "Shape Up", "37signals", "Basecamp method", "six-week cycles", "fixed time variable scope", "appetite vs estimates", "betting table", "breadboarding", "fat marker sketch", "build less", "underdo the competition", "opinionated software", "we have too many meetings", "how do we ship faster", or "stop overbuilding".

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# The 37signals Product Development Framework A system for building profitable software without bloat, bureaucracy, or burnout, distilled from three books: *Getting Real* (build less), *Rework* (say no by default), and *Shape Up* (fix time, flex scope). Use it to shape work, bet on six-week cycles, run small autonomous teams, and ship on a predictable cadence. ## Core Principle **Build less.** The best products do fewer things exceptionally well — simplicity is the destination, not the starting point. Traditional development adds; the 37signals way subtracts: build half a product (not a half-assed product), say no by default, fix the time and flex the scope. Constraints are what make great work possible — six weeks, three people, and a shaped pitch force you to find the essential version. ## Scoring **Goal: 10/10.** Rate product plans, feature scopes, and team processes 0-10 against these principles. Report the current score and the specific changes needed to reach 10/10. - **9-10:** Fixed-time cycles, shaped pitches, small teams, no backlog, opinionated defaults, clear copy - **7-8:** Mostly shaped work and small teams, but some scope creep or process overhead …

How to install
mdr add wondelai/skills/37signals-way@sha256:b6882f6f197ed4eeThe line at the top of this page pins the label v1.3.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
