WHAT IT DOES

What set_run_language does on Docx

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

RISK

Why set_run_language is rated Medium

This tool creates or modifies document properties (language metadata on text runs) without deleting data or executing arbitrary code. It is reversible—the language can be changed again. While it affects document behavior (spell-checking), it does not execute external operations, trigger destructive changes, or involve financial transactions.

From the tool's definition The tool name 'set_run_language' and description 'Set the language on a run for spell-checking purposes' indicate modification of document metadata.

set_run_language Rate-limited

set_run_language 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.
