Answer: Tools it can call, and instructions on when to call them
Foundry defines an agent as 'a model paired with instructions and tools that can reason over a request and take action', and agents act on the world through tools such as functions, OpenAPI specs, and MCP servers. A larger context window only holds more text. Fine-tuning changes how the model writes, not what it can call. A vector store retrieves passages; it files no claim and sends no reply.
