Interactively facilitate writing a short Architecture Decision Record (ADR). Use when the user wants to make and document an upfront technical or architecture decision — capturing the problem, constraints, 2-3 realistic options with tradeoffs, the chosen decision and why, risks/consequences consciously accepted, and a concrete revisit trigger. Trigger on: /create-adr, "create ADR", "write an ADR", "architecture decision record", "document this decision", "let's decide how to build X".
