Each tool has a largely distinct purpose: search queries messages, read retrieves messages in order, stats aggregates counts, export writes to a file, and chats lists available chats. The only mild overlap is that search and read both return message content, and export can cover similar bulk-retrieval ground as read, but the descriptions make the intended use cases clear.

All five names are single lowercase words with no separators, which is a consistent and predictable style. However, they mix verbs (search, read, export) and nouns (stats, chats) rather than following a single verb_noun or uniform category convention, which is a minor deviation.

Five tools is well within the appropriate 3-15 range for a Telegram message-recall server. Each tool maps to a distinct capability (query, ordered read, aggregation, bulk export, chat listing) and none feels redundant.

The read-only recall domain is well covered: search for targeted retrieval, read for chronological access, stats for aggregation, export for bulk analysis, and chats for scope discovery. A minor gap is the lack of an explicit sync/refresh or per-message lookup tool, though chats' sync age and read's since/until partially mitigate this.
