#### Consolidation-Aware Retrieval

**Gap Analysis:** No competitor has cluster prototype-based retrieval

**Recommended Enhancement:**

| Attribute                 | Value                                                           |
| ------------------------- | --------------------------------------------------------------- |
| **Competitive Gap**       | Others retrieve individual vectors, not cluster representatives |
| **Market Need**           | Efficient retrieval from massive memory stores                  |
| **Differentiation Value** | "Hierarchical memory" with abstraction                          |
| **Implementation**        | Two-stage: cluster → members                                    |

### 2. Integration Ecosystem

#### LangChain/LlamaIndex Adapters

**Gap Analysis:** PRIME needs integration with existing ecosystems

**Recommended Enhancement:**

| Attribute                 | Value                                             |
| ------------------------- | ------------------------------------------------- |
| **Description**           | `PRIMERetriever` class implementing BaseRetriever |
| **User Value**            | Drop-in replacement for existing RAG pipelines    |
| **Competitive Impact**    | Lower adoption barrier                            |
| **Implementation Effort** | Low (2-3 days per adapter)                        |

```python
# LangChain adapter
from langchain_core.retrievers import BaseRetriever

class PRIMERetriever(BaseRetriever):
    """PRIME as LangChain retriever."""

    prime_client: PRIMEClient

    def _get_relevant_documents(self, query: str) -> list[Document]:
        result = self.prime_client.process_turn(query)
        return [Document(page_content=m.content, metadata=m.metadata)
                for m in result.retrieved_memories]
```
