    Enables AI coding agents to perform deterministic database architecture audits and performance engineering for PostgreSQL and MySQL, covering migration analysis with schema health scoring, ESR-based composite index recommendations, N+1 query detection, EXPLAIN plan diagnosis, transaction and deadlock analysis, partitioning and archival design, and capacity or configuration tuning. It also generates phased Expand & Contract runbooks that turn blocking DDL into zero-downtime production migrations.

TDQS

A4.7/5.0

Scored across 12 tools

Disambiguation5/5

Each tool targets a distinct artifact-action pair: query synthesis, injection auditing, plan analysis, migration risk, dialect transpilation, index recommendation, normalization validation, telemetry masking, fixture generation, pool sizing, isolation auditing, and ORM generation. Descriptions explicitly cross-reference sibling tools ('for X, use Y instead'), eliminating the few plausible overlaps such as performance analysis vs. index recommendation.

Naming Consistency5/5

Every name follows a strict verb_noun snake_case pattern (synthesize_sql_query, audit_sql_injection_ast, detect_breaking_migrations, calculate_pool_headroom). Verbs are semantically precise and non-duplicated, so the naming reads as a coherent taxonomy.

Tool Count5/5

Twelve tools is squarely in the well-scoped range and each covers a distinct concern in the database-intelligence domain. No filler or redundant entries appear.

Completeness4/5

The surface covers schema validation, migration safety, query generation/optimization, security auditing, data provisioning, and ORM scaffolding—a full lifecycle for read-only DB intelligence. Minor gaps remain (e.g., no query-execution/EXPLAIN retrieval tool and no lock/deadlock inspection beyond isolation auditing), but agents can work around these.
