A sentence on the site does not fit a rule on tone or writing style in your own brand manual.
A tone of voice only works if it is on every page, also on the pages somebody wrote in a hurry. Nobody rereads a whole site for that. The standard here is your own manual, never a general opinion from Snaglist on what good copy is.
This check only runs with a brand manual you uploaded and tone rules you confirmed. Without a manual there is no result, and Snaglist asks you to upload one. Snaglist takes the text of up to six pages, a sample of the page types, and an AI model (Mistral, through its EU address) lays it next to your rules. It may only name a sentence that clearly breaks a numbered rule. Snaglist then checks that the sentence is literally on the page and that the rule exists. Everything else is dropped. Because a model makes this judgement, read it as a pointer: you decide. This check does not cost a crawl any pages.
Snaglist reports this as a notification. It costs 2 percent of the page in the health score. Good to know, and sometimes a deliberate choice.
In the report for your client this appears under the heading "Sentences that do not fit your tone of voice". When everything is in order, the report says: "The copy fits the tone of voice in the manual".
