AI agents call get_project_note_children to retrieve information from Repsona without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves data about sub-notes without modifying, deleting, or executing any operations. It has no side effects and presents minimal risk if misused by an AI agent, as it only exposes read access to hierarchical note structures.
