About

/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

### Assumptions
### Transforms (opposite/zero/10x)
### Reframed Ideas
- Idea … (evidence, fast test)
### Top Picks

Pairings

  • Run before /collaboration:idea-lab if you need to loosen constraints.
  • Feed winners into /collaboration:concept-forge to score/prioritize.
