AI agents call list_template_library to retrieve information from Todos without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and displays information about available templates from a local library. It performs no modifications, deletions, or external operations. The scope is explicitly local-only, limiting any potential blast radius. This is a standard Read category tool.
From the tool's definition Tool name contains 'list' and description states 'List bundled marketplace-free template library (local-only)'. This is a query/retrieval operation with no side effects.
