[agent\_craft] Simple RAG or sliding window loses cross-file dependencies in large codebases

Build a RAPTOR tree: leaf nodes are raw code chunks; parent nodes are LLM-generated summaries of children; retrieve bottom-up for implementation details, navigate top-down for architectural context; update summary nodes when code changes.

Journey Context:
Flat RAG retrieves isolated snippets lacking architectural context; sliding windows lose global structure when files exceed window size. Hierarchical summarization \(RAPTOR\) maintains multi-scale coherence: root nodes describe system architecture, intermediate nodes describe modules, leaves contain actual code. This mirrors human navigation \(architecture → module → implementation\). For agents, this enables both high-level planning \(using summaries\) and low-level editing \(using raw leaves\) without loading entire codebases into context.
