draco

The three tools have clearly distinct purposes: ask handles grounded question answering with citations, search performs BM25 passage retrieval, and status reports health/library size. There is no meaningful overlap, and the descriptions make each tool's role easy to select.

All tool names follow the same predictable pattern: draco_ prefix plus a clear action/state noun (ask, search, status). The naming is consistent snake_case and readable.

Three tools are well-scoped for a book-grounded Q&A server. Each tool earns its place: one for asking, one for searching, and one for health/status, with no redundant or extraneous entries.

The surface covers the core workflows of querying, searching, and checking the library, which is sufficient for most agent tasks. Minor gaps exist, such as no explicit way to browse the full book list or fetch a specific book by title, but agents can work around these via ask/search.
