Scored across 11 tools
Each tool has a clearly distinct purpose: listing vs describing vs sampling vs querying vs explaining. No overlapping tools that could cause confusion.
All tool names follow a consistent verb_noun snake_case pattern (get_*, list_*, describe_*, test_*, execute_*, explain_*). No mixed conventions or varied verb styles.
11 tools is well within the ideal 3-15 range and maps neatly to the domain of Snowflake exploration and querying. Each tool earns its place without bloat.
Covers the full read-side workflow: connection testing, database/schema/table/view enumeration, schema inspection, row counts, primary keys, sampling, query execution, and query planning. No critical gaps for an exploration/query-focused server.
