Use when the user asks for a recommendation, wants to compare alternatives, choose between approaches, or decide how to proceed under trade-offs. Trigger on requests like "what should I use", "which is better", "recommend", "help me decide", "what's the best way to", or "should I go with X or Y". Also use when an ongoing discussion surfaces a non-trivial decision point with multiple viable options. Do not use for purely factual questions or trivial, low-stakes, easily reversible choices.
