## Why set_default_language is rated Medium

This tool modifies site settings (the default language) in a reversible manner. It changes configuration state but does not delete data, execute arbitrary code, or cause financial transactions. The blast radius is medium because changing the default language could affect customer experience, SEO, and site behavior, but the action is easily reversible by setting a different default language.

From the tool's own definition: "Tool name 'set_default_language' and description 'Change which enabled language is the site default' indicate modification of site configuration."

## Use case

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