Scaffolds an xUnit integration test project for validating Oracle-to-PostgreSQL database migration behavior in .NET solutions. Creates the test project, transaction-rollback base class, and seed data manager. Use when setting up test infrastructure before writing migration integration tests, or when a test project is needed for Oracle-to-PostgreSQL validation.
Neo4j Java Driver v6 — driver lifecycle, Maven/Gradle setup, executableQuery, executeRead/Write managed transactions, explicit transactions, async/reactive patterns, error handling, data type mapping, connection pool tuning, causal consistency/bookmarks. Use when writing Java or Kotlin code that connects to Neo4j via GraphDatabase.driver, executableQuery, SessionConfig, executeRead, executeWrite, or TransactionCallback. Does NOT handle Cypher authoring — use neo4j-cypher-skill. Does NOT cover driver version upgrades — use neo4j-migration-skill. Does NOT cover Spring Data Neo4j (@Node, Neo4jRepository) — use neo4j-spring-data-skill.
Implement persistence layers with Spring Data JPA. Use when creating repositories, configuring entity relationships, writing queries (derived and @Query), setting up pagination, database auditing, transactions, UUID primary keys, multiple databases, and database indexing. Covers repository interfaces, JPA entities, custom queries, relationships, and performance optimization patterns.
This skill provides PostgreSQL-specific patterns for database design, optimization, and transaction management
Adapt React applications to MultiversX blockchain with wallet connection, transactions, and smart contract interactions. Use when app needs Web3, blockchain, wallet login, crypto payments, NFTs, tokens, or smart contract calls.
PostgreSQL 16 database documentation. Use for SQL queries, indexes, transactions, JSON operations, full-text search, and performance tuning.
Plan and review MySQL/InnoDB schema, indexing, query tuning, transactions, and operations. Use when creating or modifying MySQL tables, indexes, or queries; diagnosing slow/locking behavior; planning migrations; or troubleshooting replication and connection issues.
Required reference for Prisma v7 driver adapter work. Use when implementing or modifying adapters, adding database drivers, or touching SqlDriverAdapter/Transaction interfaces. Contains critical contract details not inferable from code examples — including the transaction lifecycle protocol, error mapping requirements, and verification checklist. Existing implementations do not replace this skill.
[Pragmatic DDD Architecture] How to structure **Use Cases** using DDD and Railway-Oriented Programming (neverthrow Result types). Tailored for TypeScript + drizzle-orm + node-postgres stack. **Use whenever creating or modifying any Use Case class — even simple ones like "Exists" or "List" operations — to ensure type-safe error unions, proper transactional boundaries, Value Object-only contracts, auth-first patterns, and Result-based error handling.** Includes references to working examples (Create, List, Exists patterns). Depends on 'repositories' skill.
Build Solana applications with Helius infrastructure. Covers transaction sending (Sender), asset/NFT queries (DAS API), real-time streaming (WebSockets, Laserstream), event pipelines (webhooks), priority fees, wallet analysis, and agent onboarding.
L3 Worker. Audits layer boundaries + cross-layer consistency: I/O violations, transaction boundaries (commit ownership), session ownership (DI vs local), async consistency (sync I/O in async), fire-and-forget tasks.
Error handling patterns for ERPNext/Frappe database operations. Use when handling DoesNotExistError, DuplicateEntryError, transaction failures, and query errors. Covers retry patterns and data integrity. V14/V15/V16 compatible. Triggers: database error, DoesNotExistError, DuplicateEntryError, transaction failed, query error.
