Configuration for overriding model and prompt template.

- Source: [`aws-bedrockagentcore/lib/memory/strategies/managed-strategy.ts`](https://github.com/aws/aws-cdk/blob/v2.275.0/packages/aws-cdk-lib/aws-bedrockagentcore/lib/memory/strategies/managed-strategy.ts#L40)
- Type last changed: v2.255.0 · 19 May 2026

## Example

```ts
// Create a custom semantic memory strategy
const customSemanticStrategy = agentcore.MemoryStrategy.usingSemantic({
  strategyName: "customSemanticStrategy",
  description: "Custom semantic memory strategy",
  namespaces: ["/custom/strategies/{memoryStrategyId}/actors/{actorId}"],
  customConsolidation: {
    model: bedrock.FoundationModel.fromFoundationModelId(this, 'ConsolidationModel',
      bedrock.FoundationModelIdentifier.ANTHROPIC_CLAUDE_3_5_SONNET_20241022_V2_0,
    ),
    appendToPrompt: "Custom consolidation prompt for semantic memory",
  },
  customExtraction: {
    model: bedrock.FoundationModel.fromFoundationModelId(this, 'ExtractionModel',
      bedrock.FoundationModelIdentifier.ANTHROPIC_CLAUDE_3_5_SONNET_20241022_V2_0,
    ),
    appendToPrompt: "Custom extraction prompt for semantic memory",
  },
});

// Create memory with custom strategy
const memory = new agentcore.Memory(this, "MyMemory", {
  memoryName: "my-custom-memory",
  description: "Memory with custom strategy",
  expirationDuration: cdk.Duration.days(90),
  memoryStrategies: [customSemanticStrategy],
});
```

## Properties

- `appendToPrompt`: string (required) — The prompt that will be appended to the system prompt to define the model's memory consolidation/extraction strategy.

  This configuration provides customization to how the model identifies and extracts
  relevant information for memory storage. You can use the default user prompt or create a customized one.

- `model`: [IModel](/cdk/api/v2/docs/aws-cdk-lib.aws_bedrock.IModel.html) (required) — The model to use for consolidation/extraction.
