What snow_format_date does on Serac

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

Why snow_format_date is rated Medium

An AI agent can call snow_format_date faster than any human can review: one bad instruction and it creates or modifies resources in Serac by the hundred, each call as confident as the last.

snow_format_date Rate-limited

snow_format_date 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.
