init_templates · Todos MCP: Risk & Policy

WHAT IT DOES

What init_templates does on Todos

AI agents use init_templates to create or update resources in Todos — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Todos environment.

WHY IT NEEDS A POLICY

Why init_templates needs a policy

This tool creates new template records in a local library. It is a write operation (initializing/creating templates) but is safe by design since it skips existing templates, making it non-destructive and idempotent. Blast radius is low as it only affects local template configuration.

From the tool's definition Initialize the bundled local template library. Skips templates that already exist by name.
