+**Milestone v[X.Y]: [Name]**
+
+**Goal:** [One sentence]

+**Target features:**
+- [Feature 1]
+- [Feature 2]
+- [Feature 3]
+
+**Key context:** [Any important constraints, decisions, or notes from questioning]
+```
+
+AskUserQuestion:
+- header: "Confirm?"
+- question: "Does this capture what you want to build in this milestone?"
+- options:
+  - "Looks good" — Proceed to write PROJECT.md
+  - "Adjust" — Let me correct or add details
+
+**If "Adjust":** Ask what needs changing (plain text, NOT AskUserQuestion). Incorporate changes, re-present the summary. Loop until "Looks good" is selected.
