Report #66857
[agent\_craft] RAG retrieves code snippets but agent fails to understand control flow or variable scope
Use vector search \(RAG\) only for initial file discovery, then immediately load the entire relevant file \(or AST subtree\) into context for modification, rather than operating on disconnected snippets.
Journey Context:
Vector search is great for finding where a concept lives, but terrible for understanding how it connects. Agents that try to edit code based purely on retrieved chunks often break imports, miss variable declarations, or misjudge control flow. The tradeoff is token cost vs. correctness. Loading the whole file costs more tokens but drastically reduces syntax and logic errors. Use RAG to route to the file, then read the file.
