Description

When adding memory with --strategies SUMMARIZATION, summaries appear to be written but are not incorporated (retrieved/used) in subsequent sessions. It's unclear whether this is a write-only operation or if retrieval is broken. Additionally, the docs do not clearly explain that Summarization must be wired to the memory session manager for it to work end-to-end.

Steps to Reproduce

  1. Run agentcore add memory --strategies SUMMARIZATION
  2. Start a session and interact with the agent
  3. End the session
  4. Start a new session and check whether summaries from the previous session are leveraged

Expected Behavior

Summaries from prior sessions should be incorporated and used to inform subsequent sessions, as implied by the "Get started" documentation.

Actual Behavior

Summaries do not appear to be leveraged in subsequent sessions. Users must additionally wire Summarization to the memory session manager, but this is not documented clearly. The docs at https://github.com/aws/agentcore-cli/blob/main/docs/memory.md#adding-memory-to-an-agent-without-memory need to be updated to clarify the required wiring.

                          Description
                          When adding memory with --strategies SUMMARIZATION, summaries appear to be written but are not incorporated (retrieved/used) in subsequent sessions. It's unclear whether this is a write-only operation or if retrieval is broken. Additionally, the docs do not clearly explain that Summarization must be wired to the memory session manager for it to work end-to-end.
                          Steps to Reproduce
                          1. Run agentcore add memory --strategies SUMMARIZATION
                          2. Start a session and interact with the agent
                          3. End the session
                          4. Start a new session and check whether summaries from the previous session are leveraged
                          Expected Behavior
                          Summaries from prior sessions should be incorporated and used to inform subsequent sessions, as implied by the "Get started" documentation.
                          Actual Behavior
                          Summaries do not appear to be leveraged in subsequent sessions. Users must additionally wire Summarization to the memory session manager, but this is not documented clearly. The docs at https://github.com/aws/agentcore-cli/blob/main/docs/memory.md#adding-memory-to-an-agent-without-memory need to be updated to clarify the required wiring.
