description: Day 4 (Thursday morning) of a Design Sprint - produce role plan, Five-Act interview script, trial-run checklist, and participant confirmation tracker
---

Use the `tool-design-sprint-prototype-plan` skill to produce Thursday morning's planning artifact for the day's parallel build work.

Read the skill instructions from `skills/tool-design-sprint-prototype-plan/SKILL.md` and follow them to assign the 5 canonical Sprint book roles (Maker, Stitcher, Writer, Asset Collector, Interviewer), author the prototype brief (with explicit fidelity bar), draft the Five-Act interview script (Welcome / Context / Intro / Tasks / Debrief), define the trial-run gate criteria, and confirm Friday participants.

The actual prototype build is craft work (Figma frames, Keynote slides, paper assemblies) done by the team after this skill completes. This skill plans Thursday; the build occupies the rest of the day.

Use `skills/tool-design-sprint-prototype-plan/references/TEMPLATE.md` as the output format.
