## Using multiple accounts

Use `claude setup-token` to obtain a token for each account. Apply the personal account's `CLAUDE_CODE_OAUTH_TOKEN` system-wide, put the work account's `CLAUDE_CODE_OAUTH_TOKEN` in the `.envrc` of the folder containing work projects, and have each project's `.envrc` inherit it with `source_up`. This lets you use your personal account everywhere else and your work account in work projects.

However, when I did this, commands such as `/usage` stopped working, and I do not yet know how to fix that.
