Scored across 6 tools
The tools mostly have distinct roles: recall is semantic search across sessions, scan is literal string search within one session, sessions lists metadata, get reads raw turns, sketch summarizes a session, and status reports health. The only mild overlap is between get and sketch, since both read one session, but the descriptions make their different purposes fairly clear.
All tool names are single lowercase words with no mixed casing or underscores, which is a consistent convention. The set mixes verbs (get, recall, scan, sketch) with nouns (sessions, status), so it does not follow a strict verb_noun pattern, but it remains readable and predictable.
Six tools is well within the appropriate range and each tool covers a distinct retrieval or diagnostic operation. There are no obviously redundant tools, and the surface is compact for a memory-retrieval server.
The surface covers the core read-only lifecycle for past sessions: enumerate, semantically search, literal scan, read raw turns, summarize a session, and check memory health. Minor gaps could exist around managing multiple memories or write/forget operations, but for a retrieval-focused server the coverage is strong.
