# Sprint Scaffold Apply the Filing Cabinet ($49 product) `spec_charter.md` template + the Flowstate ($299 product) `.claude/agents/pr-review.md` template to **internal Aria sprints** (not just customer-facing project tarballs). Closes the audit-trail loop: every sprint has a mission, scope, risks, acceptance criteria, and a review rubric for everything shipped under it. This skill emerged from Sprint 020 (`two_terminal_push`, 2026-05-23) where T1 and T2 shipped 11 items in parallel with zero conflicts because the sprint folder enforced clean ownership boundaries up front. ## When to use - User says "open sprint NNN" / "start sprint for X" / "new sprint" / "scaffold a sprint" / "let's sprint on Y" - You're about to start work that spans 3+ items + multiple sessions and should have one canonical home - Multiple terminals or contributors need a file-lock contract (this skill ships HANDOFF_*.md templates) ## Steps 1. **Pick the sprint number.** Look at `/opt/aria/v4/sprints/` — find the highest existing NNN and add 1. Slug is lowercase-hyphenated. ```sh ls /opt/aria/v4/sprints/ | sort -n | tail -3 ``` 2. **Create the folder + subdirs:** ```sh SPRINT=021_<slug> mkdir -p /opt/aria/v4/sprints/$SPRINT/{reference,sql,.claude/agents} ``` 3. **Write spec_charter.md** (Filing Cabinet pattern). Use the template below — pre-fill what you know, leave the rest as `TODO`: ```markdown # Sprint NNN — <Title> · spec_charter v1 **Opened:** YYYY-MM-DD *
