Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

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. |

TDQS
Scored across 7 tools
Each tool has a distinct purpose: bulk delete, single delete, list, context recall, index repair, save, and search. No two tools overlap in functionality.
All tool names follow a verb_noun pattern (e.g., save_memory, delete_memory). Even 'recall_thread' and 'delete_memories_by_session' adhere to this convention with minor additions, maintaining consistency.
With 7 tools covering create, read (list/search), delete (single/bulk), context recall, and maintenance, the count is well-scoped for a Lite ephemeral memory server.
The set covers save, list, search, delete, and context recall, but lacks a direct get-by-ID tool. While search can retrieve memories, the absence of a dedicated fetch tool is a notable gap.
