AWS code-library documentation change
Summary
Removed Go and JavaScript SDK code examples demonstrating Amazon Bedrock Runtime usage with Anthropic Claude models
Security assessment
The change deletes implementation examples but contains no evidence of security vulnerability fixes, security incident references, or security feature updates. Removal appears to be routine documentation cleanup without security implications.
