AgentCore Web Answer vs Web Search: who runs the model, what you get back, and what the managed tool decides for you
AWS announced general availability of Web Answer on Amazon Bedrock AgentCore on 5 November 2026. Web Search hands your agent ranked links and snippets and leaves synthesis to your own model. Web Answer runs the retrieval loop, model, synthesis and citation step and returns a finished cited answer through AgentCore Gateway. This piece compares the returned artifact, the permissions, the controls you keep, the $10 per 1,000 tool calls price and the limits, including what AWS's guide does not establish.

AgentCore memory poisoning: what AWS builds in, what its new write-validation pattern adds, and where the demo evidence stops
An AWS Security Blog post from 9 November 2026 separates the memory-poisoning controls AgentCore already offers (IAM namespace conditions, namespace-variable validation, Cedar policy, custom consolidation prompts, the ApplyGuardrail API) from a custom pre-write Lambda interceptor that scores each write and returns ALLOW, QUARANTINE or DENY. The custom layer is a sample you deploy, not a default setting. Its published 11-scenario demo used a keyword-overlap stand-in for embeddings, so the results do not show production accuracy or false-positive rates. Writes that bypass AgentCore Gateway, such as direct SDK calls, are not covered by the interceptor.
