What problem does it solve? Plans often contain hidden assumptions and unresolved decisions that only surface mid-implementation, causing rework. This Skill interviews you adversarially before any code is written, modeling your plan as a design tree and questioning every unresolved branch until nothing is silently assumed. ## Core Features & Use Cases - Frontier Rounds: Maps your plan as a decision tree and asks only the questions whose prerequisites are already settled, in numbered rounds with recommended answers. - Fact-Grounded Questioning: Looks up codebase facts itself using file search and terminal tools instead of asking you things it could discover. - Decision Synthesis: Summarizes all settled decisions, open items, and explicit out-of-scope boundaries, then waits for your confirmation before implementation. - Use Case: Before building an auth flow or schema migration, say "grill me on this plan" and answer structured question rounds covering edge cases, failure modes, and rollback strategy until the design is fully aligned. ## Quick Start Ask the assistant to grill you on your implementation plan for a new feature before writing any code.
