Prompt
We are setting up the logistics section for our pre-sprint brief for an upcoming healthcare portal sprint on Nov 18-19. I wrote out a multi-paragraph text explanation describing room reservations, Zoom links, Miro board setup, daily hours from 9 AM to 5 PM, and lunch breaks. Reformat this into the required structure for the brief's logistics section.

Foundation Sprint Brief
Produce the one-page brief that aligns the team on scope, decision target, participants, logistics, and success criteria before Day 1 begins. A well-built brief prevents Day 1 from opening with re-litigation of why-are-we-here; a missing or vague brief almost guarantees it.
Family contract: docs/reference/skill-families/foundation-sprint-skills-contract.md. This skill is a member of foundation-sprint-skills.
When to Use
The readiness verdict from tool-foundation-sprint-readiness is Go (or Conditional Go with preconditions cleared).
The sprint has dates blocked on calendars and you need the artifact that names what the sprint is for.
The team has prep activities scheduled and you need a written reference for what to bring.
A skeptical exec wants to know "what is the team doing for two days?" and you need an answer that fits on one page.
When NOT to Use
The sprint has already started. The brief is a prep artifact, not an in-sprint deliverable. If Day 1 is happening, run tool-foundation-sprint-basics instead.
The readiness verdict is Wait. The brief cannot fix an unready team; close the preconditions first, then re-run readiness, then invoke this skill.
The team wants a strategy document. The brief is internal prep, not a stakeholder deliverable. If a stakeholder document is needed, that is a downstream artifact.
The brief threatens to become a multi-page strategic document. Stop and reframe: the canonical brief is one page.
What This Skill Produces
A single bundled artifact with six sections:
Initiative statement and stakes: one paragraph naming what the team is sprinting on and why a wrong direction would be costly.
Decision the sprint must unlock: the open strategic question the sprint resolves. Single sentence.
Team roster with role assignments: who is in the room and what role each person plays per section of the sprint.
Day 2 afternoon move of a Foundation Sprint. Evaluates the candidate approach set through multiple lenses (4 classic plus at least 1 custom) to surface trade-offs, identify consistent winners and contradictions, and produce a top bet plus a backup plan. Use after Approach Options is signed. Lens scoring is a sense-making tool, not mathematical truth; arbitrary precision is a smell.
