The Sub-200-Line Codebase Rule
Modular simplicity that keeps your codebase clean and AI-friendly.
Software systems deteriorate when individual files grow into unmanageable monoliths. Imposing a strict 200-line limit forces disciplined architecture.
Why 200 Lines Matters
When files stay concise, every module has a single clear purpose.
- Fast Cognitive Load: Developers can review and understand an entire file in under two minutes.
- AI Pairing Resilience: Automated coding tools and language models maintain higher accuracy without context saturation.
- Easy Testing: Compact functions with explicit inputs and outputs are trivial to verify and refactor.
