+The design-tree approach and related interviewing guidance in `SKILL.md` were
+adapted from Matt Pocock's `grilling` skill, invoked by his `grill-me` skill.
+This includes tracking dependent decisions, settling prerequisites before
+asking dependent questions, investigating accessible facts, and leaving
+decisions with the user. The wording and workflow have been adapted for ADR
+brainstorming; this is not an unmodified copy of the upstream skill.
