Flow AI tool trigger
Enables a Flow to act as an AI tool, allowing AI agents (for example, OpenAI agents or MCP agents) to call the Flow as a tool during their reasoning process.
This trigger serves as the entry point for Flows that should behave like callable functions inside an AI system — receiving arguments from the AI agent, executing business logic or integrations, and returning structured output back to the agent.
