Report #5721

[agent\_craft] Agent uses semantic vector search to find code but gets back conceptually similar yet syntactically unrelated results, missing the exact function needed

Combine semantic search with structural/lexical search \(like AST-aware grep or symbol search\). Use semantic search to find the right file or module, then use lexical/structural search to find the exact function or variable within it.

Journey Context:
Semantic search is great for finding 'where is the authentication logic?' but terrible for finding 'where is the process\_payment function defined?'. Vector embeddings conflate concepts but ignore exact identifiers. A hybrid approach leverages the strengths of both: semantic search narrows the search space to the right files, and then exact-match or AST-based search pinpoints the exact symbol. This is the architecture behind effective coding tools that use repo maps.
