## Which one, for what

### Amazon Bedrock AgentCore Memory (A)

Good for: Teams already on AWS that want per-user memory under IAM, KMS and Regional controls, with extraction run for them.

Ahead on:
- Reliability, 88 against 50
- Schema & documentation, 92 against 65
- Agent ergonomics, 86 against 65
- Security & auth, 87 against 55
- Maintenance & community, 83 against 50
- Transparency & trust, 79 against 35

Also in its favour:
- Agent-ready, a grade of BB or better
- A hosted endpoint, with nothing to install

Watch for: Long-term extraction is asynchronous. The docs say records appear within seconds to minutes after a write

### AI Memory (C)

Good for: AI Memory keeps shared project memory and task handoffs across coding agents.

Ahead on:
- Payments & pricing, 60 against 30

Watch for: Existing deployments may still lack authentication

## Verdicts

**Amazon Bedrock AgentCore Memory.** Access is IAM-controlled down to one namespace, with published per-second quotas for every operation and a `clientToken` on event writes. Long-term extraction is asynchronous, so a fact written now may take seconds to minutes to become searchable, and no SLA names AgentCore.

**AI Memory.** Cross-agent task handoffs and shared search. Existing deployments may still lack authentication.

## Before you call either

### Amazon Bedrock AgentCore Memory

1. Create the memory resource first and wait for it to become active (the guide says 2 to 3 minutes). Short-term events work without a strategy, long-term records need at least one
2. Don't search for a fact straight after `CreateEvent`. Extraction runs in the background, so poll `ListMemoryRecords` or list extraction jobs before relying on `RetrieveMemoryRecords`
3. Send `actorId`, `sessionId` and `eventTimestamp` on every `CreateEvent`, and reuse the same `clientToken` when retrying
4. Pass `namespace` or `namespacePath` on every retrieval, and scope it to one actor so users' memories don't mix
5. Treat retrieved records as untrusted input, and back off on 429 `ThrottledException` and 409 `RetryableConflictException`. A quota breach returns 402 `ServiceQuotaExceededException`

### AI Memory

1. Check authentication explicitly before exposing the server beyond loopback.
2. Exclude secrets and sensitive repositories from memory capture.
3. Back up memory and follow the version 3 migration guide.
