# Design Sprint > 5-day process for validating ideas through prototyping — an AI agent skill based on *Sprint* by Jake Knapp. Published 2026-02-19 · Updated 2026-08-17 · Product & Innovation · Free and MIT-licensed Canonical: https://skills.wondel.ai/skills/design-sprint/ Source: https://github.com/wondelai/skills/tree/main/design-sprint **Install:** `npx skills add wondelai/skills/design-sprint --global` ## What is the Design Sprint skill? Ask your agent for a Design Sprint and you get Jake Knapp’s five-day process from Sprint, hour by hour: Monday’s map and target, Tuesday’s solo sketching, Wednesday’s Decider, Thursday’s facade prototype, Friday’s five customer interviews. The skill produces the artifacts — sprint questions, prototype brief, five-act interview script — rather than a summary of the method. ## Key concepts from Sprint your agent applies - **Map & Target** — Monday: map the problem space and choose a specific target area to focus the sprint on. - **Sketch Solutions** — Tuesday: generate diverse solutions individually using "Crazy 8s" and detailed solution sketches. - **Decide** — Wednesday: use structured decision-making (dot voting, Decider) to select the best approach. - **Prototype** — Thursday: build a realistic-looking prototype — just enough fidelity to test with real users. - **Test & Learn** — Friday: run 5 user interviews and identify patterns that validate or invalidate your hypothesis. ## When to use Design Sprint — and when not to Reach for it when: - The same argument about the concept has run for three months and each round adds opinions instead of evidence. - A large build starts next quarter and not one real person has tried the idea in any form. - You can hold everyone’s calendar for five days and need to end with a decision, not a workshop write-up. - Leadership has asked for a prototype demo and the honest answer is that nobody knows what to prototype yet. Reach for something else when: - The risky question is about sustained behavior at scale rather than first reactions — Lean Startup’s experiments measure that. - You need the interview technique itself more than the week around it — The Mom Test is a better use of the time. - Discovery needs to become a weekly rhythm rather than a one-off event — Continuous Discovery is built for exactly that. - Nobody owns the outcome once the sprint ends — Inspired deals with empowered teams and who is accountable for what. ## About Jake Knapp Creator of the Design Sprint at Google Ventures.

Run `npx skills add wondelai/skills/design-sprint --global`. It takes about 30 seconds and needs no account. The Design Sprint skill then works in Claude, Claude Code, Claude Cowork, Codex, Cursor, OpenClaw and Hermes Agent — anything that reads the open agentskills.io format — and your agent loads it on its own when a task calls for it. It is free and MIT-licensed, and the source is at https://github.com/wondelai/skills. ### Which book is the Design Sprint skill based on? It packages *Sprint* by Jake Knapp — creator of the Design Sprint at Google Ventures. The skill distils the book's method into instructions your agent follows while it works, covering map & target, sketch solutions and decide. It sits in the Product & Innovation part of the library. ### How is this different from Continuous Discovery? Frequency and cost. A sprint is a five-day interruption: everyone’s calendar, a Decider in the room, one high-stakes question, an answer by Friday evening. Continuous Discovery is a low-intensity habit the team runs forever — an interview a week, an opportunity tree that keeps growing, assumptions tested in small pieces. Sprints are excellent for the decision you cannot get wrong; habits are for the hundred smaller decisions after it. Running a sprint and then returning to nothing is a common and expensive pattern. ### Why does the sprint ban group brainstorming? Because Knapp found that groups produce mush. The loudest voice anchors the room, and what emerges is an average of the ideas rather than the strongest one. So Tuesday is deliberately quiet: Crazy 8s and a detailed three-panel solution sketch, done alone, then pinned up anonymously on Wednesday and voted on in silence. A single named Decider then breaks the tie on purpose. The whole design exists to produce a real choice rather than a consensus nobody privately believes. ### Do I need to read Sprint? The book is essentially a schedule with facilitation notes, and if you are running one for the first time it is genuinely reassuring to know what three o’clock on Thursday looks like. The skill holds the same structure and, more usefully, writes the materials for your specific problem. Read the book if you are the facilitator; use the skill either way, because the drudgery of a sprint is preparation, not procedure. ### Can my agent run the sprint for me? No. The value comes from real people in one room for five days and five real customers on Friday, and none of that is delegable. The skill prepares everything around it: the sprint questions, the map, the target selection, the prototype brief, the interview script, the note-taking grid, the pattern write-up afterwards. It cannot sketch for your team, it cannot be the Decider, and it certainly cannot be the five customers. Skip Friday and you have run a workshop with better stationery. ## Related - All Product & Innovation skills: https://skills.wondel.ai/skills/product/ - Jobs to Be Done: https://skills.wondel.ai/skills/jobs-to-be-done/ - Hooked UX: https://skills.wondel.ai/skills/hooked-ux/ - Improve Retention: https://skills.wondel.ai/skills/improve-retention/ - Lean Startup: https://skills.wondel.ai/skills/lean-startup/ - Continuous Discovery: https://skills.wondel.ai/skills/continuous-discovery/ - Inspired: https://skills.wondel.ai/skills/inspired-product/ - The Mom Test: https://skills.wondel.ai/skills/mom-test/ - The 37signals Way: https://skills.wondel.ai/skills/37signals-way/ - Lean Analytics: https://skills.wondel.ai/skills/lean-analytics/
