Bedrock bearer token authentication streamlined #
What
Bearer token authentication for AWS Bedrock has been refactored to use the SDK's native apiKey parameter instead of manually setting skipAuth: true and injecting an Authorization header.
Details
- Previously, when using
AWS_BEARER_TOKEN_BEDROCK, Claude Code would setskipAuth: !0and manually addAuthorization: Bearer <token>to the request headers. This has been simplified to pass the token directly asapiKey, which is the SDK's standard mechanism. - When
CLAUDE_CODE_SKIP_BEDROCK_AUTHis enabled, the code now properly extracts and preserves any existingAuthorizationheader fromdefaultHeadersconfiguration. Previously, custom authorization headers indefaultHeaderscould be ignored in certain code paths. - The
skipAuthflag is now only set whenCLAUDE_CODE_SKIP_BEDROCK_AUTHis enabled and no bearer token is available (previously it was set whenever either the skip flag or a bearer token was present).
Evidence
Bedrock client construction refactored across three code paths (search for apiKey: Y.token, apiKey: process.env.AWS_BEARER_TOKEN_BEDROCK, and the new pq_ helper that extracts authorization headers)
