What
When Claude Code shows configured provider base URLs in its status or doctor output, those values are now passed through a masking function before being displayed. This applies to the base URL entries for Anthropic, Bedrock, Vertex, Foundry, Claude-Platform-on-AWS, and Claude-Platform-on-Google-Cloud. Previously the raw value from the environment was shown as-is.
Why
Base URLs can contain account-specific or otherwise sensitive details, so masking them in status/doctor output reduces the chance of exposing that information when sharing screenshots or logs for troubleshooting.
How sure we are
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubtThe finding does not say exactly how the value is masked (e.g. partially hidden vs. redacted) or how much of the URL remains visible.
