Report #65330

[agent\_craft] Agent misses cross-file relationships or uses wrong imports when given flat file retrieval for large codebases

Construct a 'hierarchical outline' context: first provide a directory tree with 1-line docstring summaries for every file \(generated once per repo\), then wrap retrieved full-file contents in XML tags; never provide partial file snippets without the outline layer

Journey Context:
Vector retrieval alone fails on repository-scale coding because it misses structural context \(e.g., 'this file imports from utils/'\). RepoCoder and Devin evaluations show that providing the directory structure as explicit text \(not just retrieved nodes\) improves cross-file edit accuracy by 20-30%. The XML tagging prevents the model from confusing file boundaries. Alternatives: simple RAG with chunking loses file-level semantics; providing full repo exceeds token limits. The hierarchy acts as a 'table of contents' for the model's attention.
