microsoft/RPG-ZeroRepo

Implements hierarchical graph-based code generation through three phases: feature planning (using LLM-driven agents to build feature trees and component decomposition), architecture design (translating components into concrete file layouts and APIs), and iterative code generation with test-driven validation. The framework leverages Repository Planning Graphs (RPGs) that unify functional and structural views, enabling both LLM understanding via RPG-Encoder and end-to-end repository synthesis from natural language, with full checkpoint/resumption support across pipeline stages.
