The discovery pair (list_memory_tags → search_memory) and the retrieval pair (get_memory / get_memories) are each clearly explained, and the descriptions explicitly state the intended call order. The main risk is get_memory vs get_memories, which differ only by an 's' and could be misselected, though the 'max two stages' note mitigates this.

All names are snake_case with a verb_noun structure (search_memory, list_memory_tags, get_memory, get_memories), which is predictable and readable. The only blemish is that get_memory/get_memories rely on pluralization alone to distinguish a batch variant, a minor deviation from clean naming.

Four tools is a tight, well-scoped set for a read-only curated-memory server, and each tool has a distinct role in the discover-then-fetch flow. It is on the thin side, but nothing is redundant and no tool feels gratuitous.

The retrieval lifecycle is covered end to end: list tags, search by keyword, fetch one stage, fetch a small batch. Gaps are minor and arguably intentional (no write/update/delete since memories are manually maintained, and no way to enumerate all stages without tags), which agents can work around via list_memory_tags.
