Clarify root problems, assumptions, and first principles before scoping features so later specs rest on coherent reasoning instead of copied patterns.
About
Cursor plugin principle skill that forces foundational analysis: articulate the core problem, list assumptions, derive requirements from first principles, and align language so ideation and later specs share a coherent mental model.
- States first principles
- Surfaces hidden assumptions
- Defines problem precisely
- Aligns vocabulary early

Foundational Thinking
Structural decisions protect option value. Code-level decisions protect simplicity. Over-engineering is often a premature decision that closes doors. The right foundational data structure keeps doors open.
Data structures first. Get the data shape right before writing logic. The right shape makes downstream code obvious. Define core types early, trace every access pattern, and choose structures that match the dominant paths. A data-structure change late is a rewrite. Early, it is often a one-line diff.
At code level, DRY the structure, not every line. Types and data models should converge. Three similar statements still beat a premature abstraction. Prefer explicit over clever. Test behavior and edge cases, not line counts.
Concurrency corollary. Before sharing state between actors, ask "what happens if another actor modifies this concurrently?" If not "nothing", isolate.
Scaffold first. If something helps every later phase, do it first. Ask "does every subsequent phase benefit from this existing?" CI, linting, test infrastructure, and shared types are scaffold. Sequence for option value: setup before features, tests before fixes. Keep commits small and single-purpose.
Subtraction comes before scaffolding: remove dead weight first, then lay foundations.
