What problem does it solve? Ideas, plans, and designs often contain hidden assumptions, unresolved decisions, and vague edge cases that only surface during implementation, causing rework. This Skill stress-tests a concept before any building starts by systematically surfacing every open decision and forcing each one to be settled with the user. ## Core Features & Use Cases - Design-tree interrogation: Maps the subject as a tree of decisions and asks the unblocked frontier in numbered rounds, each question carrying stakes, trade-off-laden options, and a recommended answer. - Fact gathering via sub-agents: Looks up codebase facts itself instead of asking the user, dispatching sub-agents for environment questions and marking blocked questions as pending. - Plan hardening with provenance: Folds settled decisions back into an existing plan file and stamps it with a Grilled: YYYY-MM-DD line that downstream tooling reads as readiness provenance. - Use Case: Before implementing a new architecture, ask the agent to grill your plan file; it returns the same file hardened with every decision resolved and stamped, ready to be converted into issues or built. ## Quick Start Ask the agent to grill your current plan or idea and pressure-test every unresolved decision before you start building.
