CrewAI 1.15.2a1 Adds Inline Skills and Flow Stream Protocol

Full analysis

CrewAI released version 1.15.2a1 (an alpha pre-release) of its open-source multi-agent framework, introducing several new capabilities for agent builders. Key additions include support for inline skill definitions (allowing skills to be defined directly within agent configs rather than as separate modules), a stream frame protocol for Flows (CrewAI's orchestration primitive for sequencing agent work), and a new generated Flow Definition authoring skill. The release also adds 'type tool' and 'app' fields to CrewDefinition, expanding how agents and their tools can be declared.
