Clean Code is No Longer Enough: If an AI Can’t Read It, It’s Legacy Code ‣ harasim.dev

Software development now has a third audience for source code: LLMs. Code that is opaque to AI represents a new form of technical debt called 'Silicon Debt.' The post argues that clean code must evolve into 'AI-friendly' code through strict typing, property hooks, DTOs, composition over inheritance, pure functions, and interface-driven design. PHP 8.4 and Symfony 7/8 features are highlighted as tools that make code more explicit and machine-readable. The post also warns against 'Epistemic Debt' — developers losing cognitive ownership of AI-generated code — and proposes a four-layer prevention architecture (specification, contract enforcement, traceability, validation) to maintain codebase integrity as AI tools increase code volume.
