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`](../../docs/reference/skill-families/foundation-sprint-skills-contract.md). This skill is a member of `foundation-sprint-skills`.
A single bundled artifact with six sections:
1. **Initiative statement and stakes**: one paragraph naming what the team is sprinting on and why a wrong direction would be costly. 2. **Decision the sprint must unlock**: the open strategic question the sprint resolves. Single sentence. 3. **Team roster with role assignments**: who is in the room and what role each person plays per section of the sprint. 4. **Logistics plan**: dates, hours, location, format (in-person, remote, hybrid), tools, daily rhythm. 5. **Existing inputs to bring**: the research, customer examples, competitor notes, metrics, and constraints the team should reference during the sprint. 6. **Readiness reaffirmation**: a final check that the Go verdict from `tool-foundation-sprint-readiness` still holds.
See `references/TEMPLATE.md` for the canonical structure and `references/EXAMPLE.md` for the Brainshelf book-catalog brief.
| Input | What the skill does with it | |---|---| | Readiness verdict and recommendations (from `tool-foundation-sprint-readiness`) | Pulls the recommended attendees, preconditions, and pre-sprint activities into the brief; flags any precondition that has not been closed | | Initiative description | Compresses into one paragraph for the Initiative Statement section | | Team roster | Maps people to the required Foundation Sprint roles (Decider, Facilitator, PM, Design, Engineering, Customer Expert) | | Logistics constraints | Produces the dates/hours/location/format/tools matrix; flags any constraint that would force the sprint to extend beyond two days | | (Optional) Skeptical-exec talking points | Tightens the Stakes paragraph to address why-now and why-this concerns |
The brief MUST fit on one page (or one screen). The skill enforces this through structural choices, not raw character counts:
If the brief expands beyond this scope, the sprint is being over-engineered before it starts. The fix is not a longer brief; the fix is a clearer decision target.
