## Why sf_update_lwc is rated Medium

This tool modifies existing code artifacts (LWC components) in a Salesforce org. While the changes are reversible (previous versions can be restored or re-deployed), the tool directly alters production or development components that affect application behavior.

From the tool's own definition: "Updates an existing Lightning Web Component by redeploying it with updated HTML, JavaScript, or CSS. The component is redeployed via the Metadata API."
