Why prompts_update is rated Medium

This tool modifies prompt templates that affect every agent using that template. While reversible (making it Write rather than Destructive), the scope of impact is high: changing system instructions or auto-reply rules across multiple agents could cause widespread behavioral changes, miscommunications, or unintended agent actions. The blast radius justifies high severity despite the Write category.

From the tool's definition Tool explicitly performs 'Update' operations on 'prompt template's name, system instructions, or auto-reply rules.' The description states 'only provided fields are updated,' indicating reversible modification of data.
