Each tool serves a distinct purpose: describe_table shows schema, execute handles writes, list_tables lists tables, and query handles reads. No overlap or ambiguity.

Naming is inconsistent: 'describe_table' and 'list_tables' follow verb_noun, while 'execute' is a bare verb and 'query' is a noun. No uniform pattern.

Four tools is reasonable for basic database operations, covering schema inspection, reads, and writes. Could be slightly expanded, but not under- or over-scoped.

Covers essential CRUD and schema listing, but misses DDL operations like create/alter/drop table, which are common needs. Notable gap for schema modification.
