Problem Statement

According to my chat with Claude, which generated most of this text, the Claude Code VSCode extension has no UI element (sidebar, status bar, or command) that shows which account is currently authenticated. This matters because the active account determines who is billed for usage — switching between a personal and an organization account should be easy to verify at a glance, but currently isn't.

It should be dead simple to tell who might pay lots of $ for usage.

To confirm my active account, I had to manually inspect ~/.claude.json for oauthAccount.emailAddress / organizationName — this info exists on disk but isn't surfaced anywhere in the extension itself. .credentials.json (the token cache) doesn't contain the email at all, so there's no single place in the UI to check.

Suggestion: Show the authenticated account's email/org somewhere always visible — e.g. in the sidebar header, a status bar item, or a "Claude Code: Show Account" command — especially since this affects billing attribution.

Proposed Solution

Not my job to design the UI change.
