The Default Being Overridden

Left unchecked, LLMs default to:

• Parallel creation: Adding a new file/function/abstraction that duplicates one already existing, because the existing one wasn't checked for
• Complexity ratchet: Each session adds complexity; no session removes it; over time the codebase drifts from its design patterns
• Premature abstraction: Creating helper utilities, shared functions, and wrappers for single-use operations
• Unchecked dependency growth: Adding packages without considering their cost (bundle size, maintenance burden, conflict risk)
• Pattern amnesia: Implementing a pattern differently from how it's already done elsewhere in the same codebase
• Silent accumulation: File counts, function counts, and dependency counts grow without any awareness or concern

This skill overrides those defaults with a structural awareness layer.

Pre-Creation Check (Run Before Creating Anything New)

Before creating a new file, function, component, hook, utility, or API route:
