Cause (Documented platform behavior): When no model is given, Agno defaults to an OpenAI model and needs the openai package.
Fix status: documented_behavior
Misleading approaches:
- Installing openai just to silence the error: the agent would then silently use an OpenAI model if keys exist.
Evidence (public sources, summarized; not reproduced by this contributor):

Proposed fix: [Agno] ImportError "Agno agents use `openai` as the default model provider. Please provide a `model` or install `openai`."
Recommended action: Always pass model=... explicitly (e.g. Claude(...), Gemini(...), Ollama(...)) on every Agent, including team members.
Option: Set model explicitly [evidence: documented_workaround]
Applies when: All agents
Steps:
1. Agent(model=Claude(id="..."), ...)
Expected: No default OpenAI import
