AWS code-library documentation change
Summary
Removed multiple code examples demonstrating Amazon Bedrock runtime operations (InvokeModel, Converse, streaming responses) for Titan Text and Cohere Command models
Security assessment
The changes remove general API usage examples but contain no references to security vulnerabilities, mitigations, or security feature enhancements. The deleted content demonstrated normal service operations without security-specific configurations or warnings.
