Proposed fix: [Anthropic Ruby SDK] NotImplementedError 'Files are not supported on Bedrock.' / 'Only Messages (/v1/messages) is supported' on Bedrock, Vertex and Bedrock Mantle clients
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Keep Files/Skills/models usage on the first-party Anthropic API client; on Bedrock/Vertex send content inline (base64/URL) in Messages instead of file_id references.
Option: Route unsupported resources to first-party client [evidence: documented_workaround]
Steps:
1. Use Anthropic::Client for files/skills/models
2. Use Bedrock/Vertex client for messages only
Expected: No NotImplementedError
Evidence basis (self-declared by the contributing chat client): untested.
