What problem does it solve? New products and multi-week builds often fail because expensive questions about user need, scope, architecture, design, and success criteria are never asked before code exists. This Skill forces those questions upfront through a single structured review pass, preventing costly rework on decisions that are hard to reverse. ## Core Features & Use Cases - Five-lens review in one pass: A single Plan subagent evaluates idea validation, scope, engineering, design, and success criteria, returning one structured deliverable instead of five separate review documents. - Trigger discipline: Explicit rules for when the full pipeline applies (new products, multi-week builds, costly architecture decisions) versus lightweight paths for features, bug fixes, refactors, and prototypes. - Gated implementation workflow: Batches user-facing decisions into one owner question, runs a two-reviewer plan review capped at two rounds, writes the plan to docs/plans, then verifies against machine-checkable acceptance criteria after implementation. - Use Case: When starting a new product or committing to an expensive-to-change architecture, run this pipeline to get a grounded, repo-verified plan with binary success criteria before writing any code. ## Quick Start Ask the agent to run the planning pipeline on your new product idea or multi-week build plan before any implementation begins.
