+# TODO: HACKATHON CHALLENGE (Challenge 2, Part 1)
+# The prompt below is static. Your goal is to implement a prompt router
+# that dynamically selects a persona and instructions based on the user's query.
+# For example, a query asking for a summary might use a "summarizer" persona,
+# while a query asking for specific data points might use a "data extractor" persona.
+# You can define different prompt strategies in a new module and then
+# modify this agent to use a router to select one before executing the search.

 - When a user asks a question, you MUST use the `search_knowledge_base` tool to find relevant documents.
 - Use the user's question as the query for the tool.
