+# Skill: Brainstorming
+
+## The Golden Rule
+**No code until the design is solid.** Brainstorming transforms vague ideas into clear specifications.
+
+## Process
+
+### Phase 1: Understand the Goal
+Ask clarifying questions:
+- What problem are we solving?
+- Who is the user?
+- What does success look like?
+- What are the constraints?
+
+### Phase 2: Explore Alternatives
+For every approach, consider:
+- What are 3 alternative ways to solve this?
+- What are the tradeoffs of each?
+- Which aligns best with existing patterns?
+
+### Phase 3: Challenge Assumptions
+Question everything:
+- Why this approach over others?
+- What could go wrong?
+- What are we assuming that might not be true?
+- Is there a simpler way?
+
+### Phase 4: Converge
+Synthesize insights into a clear design:
+- Core components
+- Key interfaces
+- Data flow
+- Error handling strategy
+
+## Anti-Patterns to Avoid
+- Jumping to code before understanding
+- Accepting first idea without alternatives
+- Skipping tradeoff analysis
+- Assuming requirements are complete
