## Why meta_ads_split_tests_create is rated Medium

This tool creates a new split test campaign in Meta Ads, which is a reversible write operation that commits advertising spend and marketing strategy changes. Although write operations are typically lower severity, the financial implications of autonomous split test creation (potential uncontrolled ad spend, campaign changes, and strategic commitments) elevates this to 'high' severity.

From the tool's own definition: "Tool name 'meta_ads_split_tests_create' and description 'Creates a new Split Test. Returns the new study_id' indicate creation of a new resource in Meta Ads."

## Use case
