# ex — structured discussion skill Analyze complex problems with a fixed thinking skeleton. **Output analysis only; do not modify code.** ## Entry: complexity check When the question arrives, **first judge complexity**: - **Simple problem** → answer directly, **do not apply the methodology** (KISS) - **Complex problem** → run the full 6-step skeleton below Treat as complex if any of these holds: - Multiple candidate solutions need trade-off - Multiple hypotheses need verification - Spans multiple modules / systems / layers - The user explicitly asks for deep discussion ## Methodology skeleton (complex problems only) Run in order, **in one pass, without stopping to ask the user**: ``` 1. Problem study Clarify the problem itself through What / Why / How 2. Diverge Enumerate candidate hypotheses, solutions, perspectives 3. Converge Pick the top 1-3 4. Diverge again Deep-dive into the chosen ones (details, risks, edge cases) 5. Iterate-verify Verify key hypotheses via code search / web search / bash experiments 6. Summarize Conclude; use a comparison matrix when multiple options sit side by side ``` ### What / Why / How facets (cross-cutting) - **What**: what is the problem / solution, what is the boundary - **Why**: why does this problem exist, why pick this solution - **How**: how to implement / land / verify it ## Execution rules ### Run once, never interrupt the user - **Never call AskUserQuestion** - When information is missing → explic...
