Basic Advisor
=============
The simplest usage of AdvisorTools: give your agent a single advisor model
it can ask for feedback, a second opinion, or additional context.

How it works:
1. The primary agent (OpenAI) drafts a response
2. It calls `ask_advisor` with a specific question and relevant context
3. The advisor (Gemini) answers without seeing the rest of the conversation
4. The primary agent decides what to incorporate into its final answer

Unlike a critique loop, the agent stays in control: advisor responses are
advice, not instructions.
