CrewAI

A multi-agent orchestration framework (Moura, 2024) that organises agents into crews with role/goal/backstory triads and process-driven coordination (sequential, parallel, hierarchical). Maps to Pattern 4 (Role-Based Crew) in the taxonomy.

Nuclear Relevance

Limitation: Rigid role structures cannot accommodate tasks that cross predefined role boundaries. Concurrency is partial (parallel process mode). Not designed for Pattern 9 (shared room, concurrent, human-as-peer).

Referenced in Report 6 as one of three frameworks (alongside AutoGen and LangGraph) that Level 6 prototyping could adopt for multi-agent architectural decisions.
