What problem does it solve? Plans and decisions often contain hidden assumptions and unexplored branches. This Skill systematically interrogates an idea by mapping it as a design tree and asking every reachable question, so nothing is left silently assumed before acting. ## Core Features & Use Cases - Design Tree Mapping: Models a plan as a tree of decisions where each choice branches into dependent sub-decisions. - Frontier-Based Rounds: Asks all currently answerable questions in one numbered round, each with a recommended answer, then recomputes the frontier after the user replies. - Fact-Finding via Sub-Agents: Dispatches sub-agents to look up environmental facts instead of asking the user for information that can be retrieved directly. - Use Case: Before starting a major refactor, have the Skill grill you on architecture, rollout strategy, and edge cases until every decision is explicitly settled and confirmed. ## Quick Start Ask the assistant to grill you on your plan for launching a new feature and answer each numbered round of questions until the frontier is empty.
