WHAT IT DOES

What write_template_library does on Todos

AI agents use write_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.

RISK

Why write_template_library is rated Medium

This tool creates or modifies JSON files by writing template library data to the filesystem. While reversible (files can be edited or deleted), it alters stored data and could overwrite existing template configurations. The impact is contained to local template files rather than critical system data, justifying 'Write' category with medium severity.

From the tool's definition Tool name contains 'write' and description states 'Write the bundled local template library to editable JSON files', indicating data creation/modification operations that persist to disk.

write_template_library Rate-limited

write_template_library stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
