What this skill does

/collaboration:assumption-buster Use when the team feels boxed in or every idea sounds the same. Inputs Topic or problem statement Known assumptions/constraints (even if informal) Optional mode flag: --opposite, --zero, or --10x Steps 1. List core assumptions (facts, beliefs, constraints). 2. Transform each via chosen operator (opposite/zero/10x). 3. Generate 1–2 reframed ideas per transformed assumption. 4. Capture evidence to collect and a fast test for each idea. 5. Pick the most promising 2–3 and move to /ctx:plan or Tasks. Output Template Pairings Run before /collaboration:idea-lab if you need to loosen constraints. Feed winners into /collaboration:concept-forge to score/prioritize.
