[BUG] Claude using AWS provided inference profiles when application inference profiles are set

Environment

• Platform (select one):
• [ ] Anthropic API
• [x] AWS Bedrock
• [ ] Google Vertex AI
• [ ] Other: <!-- specify -->
• Claude CLI version: 1.0.85
• Operating System: AlmaLinux 9.5
• Terminal: Ghostty

Bug Description

We are using application inference profiles in our account for Claude Code's access to models. This is so we can track costs and have other tagging. We are setting $ANTHROPIC_MODEL and $ANTHROPIC_SMALL_FAST_MODEL to application inference profiles for 4 Sonnet and 3.5 Haiku respectively. However, when /statusline is used (and sometimes at other times), the following error is thrown:

API Error (403 {"Message":"User: arn:aws:sts::XXXXXXXXX:assumed-role/XXXXXXXX/XXX@XXXXX.com is not authorized to perform: bedrock:InvokeModel on resource: arn:aws:bedrock:us-west-2:XXXXXXXXX:inference-profile/us.anthropic.claude-sonnet-4-20250514-v1:0 because no identity-based policy allows the bedrock:InvokeModel action"}) · Retrying in 1 seconds… (attempt 1/10)

Our role doesn't allow direct access to the AWS provided inference profiles. Access to foundation models is conditional. Here is a redacted IAM policy:

  "PolicyVersion": {

      "Statement": [
        {
          "Action": [

        },

                # [...]
              ]
            }
          },
          "Effect": "Allow",
          "Resource": "*"
        }
      ],
      "Version": "2012-10-17"

    "IsDefaultVersion": true,

  }
}

Steps to Reproduce

1. Set $CLAUDE_CODE_USE_BEDROCK=1 and $ANTHROPIC_MODEL and $ANTHROPIC_SMALL_FAST_MODEL
2. run Claude Code with /statusline

Expected Behavior

/statusline would throw no errors and use the provided application inference profiles.

Actual Behavior

The API error above.
