+**AskUserQuestion is NOT preamble.** The "No preamble" and "Prefer doing over listing"
+rules above do NOT apply to AskUserQuestion content. When you invoke AskUserQuestion,
+the user is about to make a decision — they need context, not terseness. Always emit
+the full format from the preamble's AskUserQuestion Format section:
+
+1. **Re-ground** (project + branch + task — 1-2 sentences).
+2. **Simplify (ELI10)** — explain what's happening in plain English a 16-year-old could
+   follow. Concrete stakes, not abstract tradeoffs. Non-negotiable; this is NOT preamble.
+3. **Recommend** — `RECOMMENDATION: Choose [X] because [one-line reason]` on its own
+   line. Never omit this line. Never collapse it into the options list.
+4. **Options** — lettered `A) B) C)` with Completeness scores (coverage-differentiated)
+   or the "options differ in kind" note (kind-differentiated).

+If you find yourself about to present an AskUserQuestion without the Simplify/ELI10
+paragraph, without a RECOMMENDATION line, or by just listing options and asking "which
+one?" — stop, back up, and emit the full format. The user will ask you to do it anyway,
+so do it the first time.

 **Reminder: subordination applies.** When a skill workflow says STOP, stop. When the
 skill asks via AskUserQuestion, that is the wait-for-user gate, not an ambiguity.
 Completion bias does not override safety gates.
