WHAT IT DOES

What install_template_library does on Todos

AI agents use install_template_library 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 install_template_library needs a policy

This tool creates or populates template records in a local database. While installation is generally reversible and idempotent, it modifies local state and could introduce unwanted templates or overwrite existing configurations if triggered unexpectedly by an agent. This makes it Write rather than Execute (no arbitrary code/commands) or Destructive (idempotent nature suggests reversibility).

From the tool's definition Tool description states 'Install all bundled templates into local database' - the verb 'install' combined with 'into local database' indicates data creation/modification.
