Identify Assumptions Existing

This runs a structured devil's advocate exercise on feature ideas for existing products, forcing you to think through what could go wrong from PM, designer, and engineer perspectives. It categorizes assumptions into four buckets (Value, Usability, Viability, Feasibility) and asks you to rate confidence and suggest tests for each. Useful when you're about to commit resources to something and want to find the gotchas before they find you. The multi-perspective approach is smart because it catches blind spots you'd miss if you only thought from your own role. Works best when you feed it context like PRDs or design files, though it'll run on a verbal description too.
