gh-auth-isolation

To switch GitHub accounts safely, you can isolate credentials using temporary config directories and environment variables. This prevents cross-account credential leakage by ensuring each agent operation runs with the intended identity rather than the global default.

GitHub CLI defaults to your EMU account because workflows running across Enterprise Managed User and personal accounts often default to the EMU identity. You need to detect the active identity and isolate credentials before pushing to personal forks.

You can extract a specific account's token using the GitHub CLI token command. This allows you to use the targeted token for actions like creating PRs without altering your global default authentication settings.

Yes, this approach supports working with multiple repositories in parallel. It creates safe, isolated contexts using config directories and environment variables to prevent credential leakage across concurrent multi-account operations.

The best way to manage GitHub identity isolation is to detect the active identity first, then use isolated config contexts and shell-level aliases. This provides robust fallbacks and clear error paths for automated agent workflows.

If GitHub authentication detection fails, the workflow provides robust fallbacks and clear error paths. This ensures that operations do not proceed with incorrect credentials, preventing failed pushes or PRs across EMU and personal accounts.
