Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| explain_query_planA | Executes EXPLAIN QUERY PLAN on a SQL query and flags FULL TABLE SCANs, missing indexes, and high-cost operations. |
| inspect_table_schemaA | Returns detailed schema info for a table: column types, nullability, primary keys, foreign keys, and index coverage metrics. |
| dry_run_migrationA | Executes a DDL migration inside an isolated SAVEPOINT, evaluates risks, then ALWAYS rolls back. Returns risk assessment and guardrail warnings. |
| suggest_optimal_indexesB | Analyzes a SQL query or table and generates precise CREATE INDEX recommendations with performance improvement rationale. |
| seed_demo_databaseB | Initializes the in-memory database with high-volume sample tables (users, orders, transactions) intentionally without indexes. |

Scored across 5 tools
Each tool targets a distinct action: plan explanation, schema inspection, migration dry-run, index suggestion, and demo seeding. There is mild conceptual overlap between explain_query_plan and suggest_optimal_indexes since both analyze query performance, but their outputs (diagnostics vs. CREATE INDEX recommendations) are clearly delineated.
All names use snake_case and begin with an action verb, forming a readable pattern. dry_run_migration deviates slightly as a compound modifier+noun rather than a clean verb_noun, but overall the convention is predictable.
Five tightly scoped tools, each filling a clear role in the query-optimization and migration-safety workflow. Nothing feels redundant or padded.
The guardrail workflow (inspect schema, dry-run migration, suggest indexes, explain plans) is coherent, but there is no way to list tables/indexes or actually apply a migration, and index recommendations cannot be executed or dropped. seed_demo_database is a demo aid rather than a true domain operation, leaving notable lifecycle gaps.
