# Assumption Challenge

Attacks a specific assumption adversarially — constructing the strongest argument for why it might be wrong, proposing an alternative assumption, and assessing the impact on the overall decision if the assumption fails.

## Execution

Spawns a subagent that takes a single assumption and builds the strongest possible case against it.

## Why Subagent

- Challenge requires adversarial mindset isolated from the assumption-maker
- Each assumption deserves focused, dedicated attack
- Isolation prevents the challenger from being "too kind" to assumptions

## HARD-GATE

Output must include:
- Challenge argument with evidence or reasoning
- At least 1 alternative assumption (what if the opposite is true?)
- Impact assessment if the assumption is wrong
- Confidence in the challenge itself (is this a real threat or theoretical?)
