Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| mnemostack_healthB | Check health of mnemostack components (embedding, vector store, optional graph). |
| mnemostack_searchA | Hybrid recall over indexed memories. Returns top-K results ranked by reciprocal rank fusion of BM25 and semantic search. Each result has id, text, score, sources, payload. |
| mnemostack_answerB | Generate concise factual answer from retrieved memories. Uses hybrid recall to find relevant memories, then an LLM inference layer to synthesize a short answer with confidence score and citations. Returns: answer text, confidence (0.0-1.0), sources, fallback_recommended. |
| mnemostack_feedbackA | Record explicit feedback for stateful recall learning. Use signal='clicked' to also record inhibition-of-return exposure. Pass retriever labels from mnemostack_search results as sources so Q-learning can update source weights. |
