-"""Agent construction for the RAG system.
+"""Legacy agent module.
 
-The agent uses the modern LangChain 1.x interfaces.
-It is built from a ChatOllama LLM and the tools defined in ``rag_tools``.
+This file is kept only for backward compatibility. It re‑exports the
+implementation from :mod:`src.agent` and then deletes itself to avoid
+conflicts with the new package structure.
