| 3 | # Design Sprint Brief |
| 4 | |
| 5 | Produce the brief that aligns the team on challenge, sprint questions, participants, customer recruiting, prototype medium, interview format, logistics, and success criteria before Monday begins. A well-built brief prevents Monday morning from opening with re-litigation of "what are we testing this week?"; a missing or vague brief almost guarantees it. |

| 9 | ## When to Use |
| 10 | |
| 11 | - The readiness verdict from `tool-design-sprint-readiness` is Go (or Conditional Go with preconditions cleared). |
| 12 | - The sprint has dates blocked on calendars and you need the artifact that names what the sprint is for. |
| 13 | - The team has customer recruiting active and you need to commit a recruiting plan, honorarium budget, and Friday schedule before recruiting closes. |
| 14 | - A skeptical exec wants to know "what is the team doing for five days plus customer cost?" and you need an answer that fits on two pages. |
| 15 | |
| 16 | ## When NOT to Use |
| 17 | |
| 18 | - The sprint has already started. The brief is a prep artifact, not an in-sprint deliverable. If Monday is happening, run `tool-design-sprint-map-and-target` instead. |
| 19 | - The readiness verdict is Wait. The brief cannot fix an unready team; close the preconditions first, then re-run readiness, then invoke this skill. |
| 20 | - The team wants a stakeholder strategy document. The brief is internal prep, not an external deliverable. If a stakeholder document is needed, that is a downstream artifact (the Friday scorecard or the next-step memo). |
| 21 | - Customer recruiting has not started. The brief locks the recruiting plan but cannot replace the recruiter. If no recruiter is named, go back to readiness Wait verdict. |

| 23 | ## What This Skill Produces |
| 24 | |
| 25 | A single bundled artifact with nine sections: |
| 26 | |
| 27 | 1. **Challenge statement and why-now**: one paragraph naming the testable challenge and the urgency that justifies a sprint this week vs. later. |
| 28 | 2. **Sprint questions**: 2-4 specific questions the Friday testing answers. The highest-risk assumption from any prior Foundation Sprint becomes the lead question. |
| 29 | 3. **Decider attendance windows**: the load-bearing moments (Mon AM, Wed AM, Fri PM at minimum); fully blocked if available. |
| 30 | 4. **Team roster with role assignments**: who is in the room each day and what role each person plays through the week. |
| 31 | 5. **Customer recruiting plan**: target profile, source, count, incentive, recruiter owner, recruiting deadline, Friday schedule. |
| 32 | 6. **Prototype medium decision**: clickable, slideware, service role-play, paper, physical mock, or other; with rationale. |
| 33 | 7. **Interview format**: live or remote; moderated or unmoderated; recording and consent posture; observer-room setup. |
| 34 | 8. **Logistics plan**: dates, hours, location, format (in-person, remote, hybrid), tools, daily rhythm. |
| 35 | 9. **Success criteria**: observable outcomes that mark the sprint successful or not. |

| 39 | ## Inference Inputs |
| 40 | |
| 41 | | Input | What the skill does with it | |
| 42 | |---|---| |
| 43 | | Readiness verdict and recommendations (from `tool-design-sprint-readiness`) | Pulls the recommended attendees, customer recruiting plan, pre-sprint activities, and prototype medium proposal; flags any precondition that has not been closed | |
| 44 | | Challenge description | Compresses into the Challenge Statement |
