AI agents call submission_guide to retrieve information from Vivioo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves informational content (submission guidelines, valid fields, examples) without creating, modifying, deleting, or executing any operations. It is a straightforward read/query action that informs users before they perform other actions on the platform.
