AWS bedrock-agentcore documentation change

Service: bedrock-agentcore · 2026-04-10 · Documentation low

File: bedrock-agentcore/latest/devguide/gateway-create.md

Summary

Changed heading style and restructured note about semantic search, including IAM permission requirement for enabling semantic search.

Security assessment

The change adds documentation about the required IAM action (bedrock-agentcore:SynchronizeGatewayTargets) for creating a gateway with semantic search, which is a security-related configuration detail. This helps users understand the necessary permissions for enabling this feature, but does not address a specific security vulnerability.
