RPG: A Repository Planning Graph for Unified and Scalable Codebase Generation

Understand

Large language models excel at generating individual functions or single files of code, yet generating complete repositories from scratch remains a fundamental challenge.

• This capability is key to building coherent software systems from high-level specifications and realizing the full potential of automated code generation.
• The process requires planning at two levels: deciding what features and modules to build (proposal stage) and defining their implementation details (implementation stage).
• Current approaches rely on natural language planning, which often produces unclear specifications, misaligned components, and brittle designs due to its inherent ambiguity and lack of structure.
