v0.3.8

Database-engineering team — agents (schema-architect, query-performance-engineer, migration-engineer, db-reliability-engineer) for the OPERATIONAL/transactional data layer (OLTP): relational schema design and normalization (and when to denormalize), indexing strategy and query/EXPLAIN-plan tuning, safe zero-downtime schema migrations (expand/contract), and connection-pooling, transactions/isolation, replication, and backup/restore reliability. Postgres-leaning, principles portable to MySQL/SQL Server; NoSQL access-pattern guidance where it fits. skills, a decision-tree knowledge bank (index-choice + migration-safety trees + a dated 2026 capability map), best-practices, templates, commands, an advisory hook. Distinct from data-platform (analytics/ELT/warehouse) and analytics-engineering (dbt). Seams: ELT/warehouse -> data-platform, ORM/app data-access -> backend-engineering, managed DB infra -> cloud plugins. Requires ravenclaude-core@>=0.7.0.

Included Skills5

connection-pool-tuningskills/connection-pool-tuning/SKILL.md

Playbook for sizing and configuring a database connection pool (PgBouncer or application-level) — calculating the right pool size, choosing the pooling mode, diagnosing pool exhaustion, and avoiding the common over-provisioning trap.

db-reliabilityskills/db-reliability/SKILL.md

Operate the database reliably: pool connections with sane limits, choose the isolation level deliberately (knowing its anomalies), keep transactions short, route replica reads carefully, and test restores — a backup is only real if you've restored it.

query-and-index-tuningskills/query-and-index-tuning/SKILL.md

Tune queries with evidence: read EXPLAIN (ANALYZE, BUFFERS) first, choose the right index type and column order (B-tree/partial/composite/covering/GIN), rewrite to be sargable, kill N+1 at the SQL level, and keep statistics fresh.

relational-schema-designskills/relational-schema-design/SKILL.md

Design a correct relational schema: normalize to 3NF, denormalize only with measured evidence and a named consistency cost, push constraints (PK/FK/UNIQUE/CHECK/NOT NULL) into the database, and choose precise data types.

safe-schema-migrationsskills/safe-schema-migrations/SKILL.md

Evolve schemas without downtime: expand/contract (add -> backfill in batches -> switch -> drop) across separate deploys, lock-aware DDL (create indexes CONCURRENTLY, nullable-add-then-validate), reversibility, and ordered versioned migrations.
