Report #99809
[agent\_craft] Generic text embeddings retrieve irrelevant files when answering questions about a codebase.
Index code with small chunks \(200-800 tokens\) centered on functions/classes, include structural context \(signatures, call graph neighbors, imports\), and use code-aware retrievers or rerankers. For repo-level tasks, retrieve supportive code from docs, tests, and implementations together.
Journey Context:
CodeRAG-Bench shows code generation gains when retrieval supplies functionally relevant snippets, but standard retrievers struggle with limited lexical overlap. Code has syntax and dependency structure that pure semantic similarity misses; graph-aware retrieval and chunk sizes around a few hundred tokens work best.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
