+### Recording trace markers
+
+Custom commands can record [trace markers](/api/browser/context#mark) for the test that triggered them through `context.mark`. This is the server-side equivalent of `page.mark` and helps annotate the [trace view](/guide/browser/trace-view) with custom actions performed inside a command.
+
+```ts
+import type { BrowserCommand } from 'vitest/node'
+
+export const uploadFixture: BrowserCommand<[name: string]> = async (
+  context,
+  name,
+) => {
+  await context.mark(`upload start: ${name}`, { kind: 'action' })
+  // ... do server-side work
+  await context.mark(`upload done: ${name}`, { kind: 'action' })
+}
+```
+
+`context.mark` is a no-op when browser tracing is not enabled or no test is currently running in the session. Unlike `page.mark`, it does not accept a callback form.
+
 ### Custom `playwright` commands
 
 Vitest exposes several `playwright` specific properties on the command context.

 ::: tip
 This method is useful only when [`browser.trace`](/config/browser/trace) is enabled.
+
+A server-side equivalent is available on the [`BrowserCommandContext`](/api/browser/commands#recording-trace-markers) so [custom commands](/api/browser/commands#custom-commands) can record markers attributed to the test that triggered them.
