Deep Inquiry · aethon-chrysean bundle Rigorous problem-solving via bilingual research (Chinese + English), proactive query expansion, and interdisciplinary reasoning. Challenges before confirming, connects distant domains, never fabricates. Triggers on: any request for a solution, explanation, analysis, recommendation, comparison, debugging, architectural decision, or concept clarification. Also triggers on: "how does X work", "why does X happen", "best approach for", "help me understand", "explain X", "compare X and Y", "I'm stuck on", "what am I missing", any problem-solving prompt, or any question where accuracy matters. Triggers on casual phrasing like "what's the deal with X". Does NOT trigger for pure creative writing, simple greetings, or tasks handled by more specific skills (st-formula-explainer, st-framework-to-pytorch, spatial-transcriptomics-validator).
