Description of the problem

Docs said that callback function in describe:

declaring all subtests and subsuites. The first argument to this function is a SuiteContext object.

But in fact the first argument is array with SuiteContext:

import { describe } from 'node:test'

x.describe(function (suiteContext) {
    console.log(Array.isArray(suiteContext))     // true
    console.log(suiteContext[0])                 //  SuiteContext {}
})
