Scenario
Research assistant framework recommendation
Research assistants often map well to role-based collaboration: search, synthesis, critique, and final answer. CrewAI is fast for that mental model, while LangGraph becomes better as state and governance requirements grow.

Scenario-specific FAQs
Is a role-playing framework necessary?
No. A role-playing framework helps when the workflow benefits from explicit researcher, critic, and writer roles. If the process is mostly retrieval plus answer generation, a simpler graph can be cheaper and easier to operate.
What is the main production risk?
The main risk is unsourced synthesis. Any research assistant should require citations, source freshness checks, and a refusal path when sources conflict or confidence is low.
