AI agents call vikunja_list_task_comments to retrieve information from Vikunja without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing comments associated with a task. It performs a read-only operation that does not create, modify, delete, or execute any actions. The 'list' operation is inherently a Read operation with minimal security risk—the worst case is exposure of comment data the user already has access to.
