Report #82668

[agent\_craft] RAG pipeline injects irrelevant code snippets into context, confusing the agent and causing hallucinated dependencies

Use exact symbol matching \(like AST lookups via Tree-sitter\) over pure vector similarity for code retrieval. Map the repository structure first, then retrieve only the specific definitions needed.

Journey Context:
Vector embeddings for code often retrieve syntactically similar but semantically unrelated functions \(e.g., multiple handle\_error functions in different modules\). Injecting these causes the agent to mix up APIs. AST-based retrieval or a repo map prevents context pollution by ensuring exact symbol resolution.
