What's Wrong?

When opening Claude, if an AWS token refresh command is present in ~/.claude/settings.json at "awsAuthRefresh", claude will loop asking for a new auth token (and prompting a browser open) every few seconds. Passing the login challenge (or denying it) does not stop the loop.

A user cannot get past this point.

Example ~/.claude/settings.json snippet:

{
   "awsAuthRefresh": "aws sso login --profile <profile>",
   "env": {
     "AWS_PROFILE": "<profile>",
     "AWS_REGION": "us-west-2",
     "CLAUDE_CODE_MAX_OUTPUT_TOKENS": "16384",
     "CLAUDE_CODE_USE_BEDROCK": "1",
     "DISABLE_AUTOUPDATER": "1"
   },

What Should Happen?

Claude should successful launch, check if the current auth token is valid and run auth once if necessary to get a valid token. It should then be ready to accept messages after that.

Possible regression of #9027 although possibly unrelated.

Reopening as it was not fixed in 2.0.56

Is there a fix or workaround for this???

[sagarrth]

Still happening on 2.0.76. Is there any solution for this?

Hate to be a "me too", but this is breaking the flow for dozens of people here at my org.
