Pass per-request dependencies through AgentOS
=============================================
AgentOS accepts a JSON ``dependencies`` form field on run requests and passes
the values into the agent's instruction templates. The client supplies a robot
name for one request and verifies that the served agent used it.
Prerequisites: OPENAI_API_KEY
Run: .venvs/demo/bin/python cookbook/05_agent_os/06_customize/dependencies.py
Try: Run this file with --demo in another terminal
