Under the hood
The internal API client builder gained a permissionContext parameter and a querySource setting
What
The internal function that builds the Anthropic API client, handling headers, authentication, and provider routing for Bedrock, Vertex, Foundry, gateway, and similar setups, now accepts a new querySource parameter, which defaults to the existing source value, and a new permissionContext parameter. Some existing fields were also renamed to agentContext, credentials, and storageV5.
Why
This finding shows the API client builder gaining new inputs but does not describe what they change in the client's behavior.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
What permissionContext and querySource actually affect in the client's behavior is not described in this finding.
