assumption-challenger
About
The Assumption Challenger skill systematically identifies and stress-tests implicit assumptions in technical plans and proposals. It is designed for use when validating roadmaps, reviewing architecture, or assessing decisions to surface hidden risks before they lead to failure. This helps developers preemptively challenge unvalidated claims about timelines, resources, and technical capabilities.
