What problem does it solve? Engineers often write logic before settling core data structures, leading to late-stage rewrites, premature abstractions, and unsafe shared state between concurrent actors. This Skill provides a decision framework for getting foundations right first. ## Core Features & Use Cases - Data Structures First: Prompts you to define core types early, trace access patterns, and match structures to dominant code paths before writing logic. - Scaffold Sequencing: Orders work so CI, linting, test infrastructure, and shared types land before features, keeping commits small and single-purpose. - Concurrency Corollary: Asks what happens when another actor modifies shared state, and isolates state when the answer is not "nothing". - Use Case: Before starting a new service, apply this Skill to choose the core data model, sequence setup work ahead of features, and decide which state must be isolated between workers. ## Quick Start Ask the agent to apply foundational thinking to review the data structures and work sequencing for your next feature before writing any logic.
