What steps will reproduce the bug?

const test = require('node:test');

test('Parent', t => {
	t.test.only('Child only', () => {});
	t.test.skip('Child skip', () => {});
	t.test.todo('Child todo', () => {});
});

Run with node --test <file> (same result without the --test flag)

How often does it reproduce? Is there a required condition?

Consistently

What is the expected behavior? Why is that the expected behavior?

All functions work as described here: https://nodejs.org/docs/latest-v20.x/api/test.html#subtests

This method behaves identically to the top level test() function. The following example demonstrates the creation of a top level test with two subtests.

What do you see instead?

TypeError [Error]: t.test.todo is not a function

TypeError [Error]: t.test.skip is not a function

TypeError [Error]: t.test.only is not a function

Additional information

These functions work for top-level test, they don't work for nested tests.
Maybe it doesn't make sense to expose those functions for subtests (use just describe - maybe it's enough), but in that case the documentation is misleading

从 node:test 子测试 API 入口开始，使用 node --test 或不使用该标志复现所提供的嵌套测试。将 t.test.only、t.test.skip 和 t.test.todo 的文档行为与观察到的 TypeErrors 进行比较；当嵌套 API 的行为与文档对预期行为达成一致时，即表示完成。
