When an existing Claude Platform on AWS session is detected, a new "Claude Platform on AWS · refresh credentials" option appears in the 3rd-party platform setup screen.
Details
- Invokes the
awsAuthRefreshcommand configured in your settings. - On success, shows "AWS credentials refreshed." and lets you continue.
- On failure, shows a clear error message and suggests running the command manually in a separate terminal.
- Only appears when an active AWS session context is available.
Evidence
