Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| search_memoryA | Hybrid (vector + BM25) search over stored memories. Call this at the start of every user turn. NOTE: Lite memories expire 7d after they were saved. |
| save_memoryA | Save a memory entry (Lite: 7-day TTL). Auto-deduplicates exact and near-duplicate content. Long content (>chunk_threshold chars) is chunked with a parent-document for verbatim recall. |
| list_memoriesA | List stored memories newest first. Parent documents shown with [doc×N] tag. |
| delete_memoryA | Delete a memory by ID. If the ID is a parent document (doc:), cascades to all child chunks. |
| delete_memories_by_sessionA | Delete every memory (singles, parent docs, child chunks, sha guards) whose session_id matches. Scoped to the configured owner. Use this to wrap up a finished project or reset a polluted session before TTL expiry. IRREVERSIBLE — confirm session_id with the user first. |
| repair_memoryB | Re-ensure the RediSearch index (idempotent). Returns {status, message}. |
| recall_threadA | §4.3.1 — Retrieve the memories sharing a turn_id plus N entries before and after in chronological order. Use this when a search_memory hit lacks enough context: pass the hit's turn_id here to surface the surrounding conversation thread. Returns {status:'not_found'} if turn_id is unknown. |
