Master SQLAlchemy 2.0+ Async Patterns for AI Agents

Master SQLAlchemy 2.0+ Async Patterns for AI Agents

This skill equips AI agents with comprehensive SQLAlchemy 2.0+ asynchronous patterns for PostgreSQL databases. It guides users through the implementation of type-safe declarative models, complex relationships, eager loading strategies, transaction management, and Alembic migrations. This is specifically tailored for use with SQLAlchemy 2.0 or 2.1, focusing solely on async execution models and PostgreSQL compatibility.

What this skill does

• Provides examples and patterns for writing declarative models and ORM models using SQLAlchemy 2.0+.
• Facilitates the addition of columns, mapped columns, and foreign keys onto tables.
• Defines table relationships and indexes to streamline database interactions.
• Implements strategies like selectinload, joinedload, and load_only to optimize query loading times.
• Guides configuration of async sessions and the execution of queries with session.execute.
• Assists in rectifying N+1 query issues and performing bulk inserts or upserts.
• Supports usage of advanced PostgreSQL types, including JSONB.
• Instructs on writing effective migration models and executing SQLAlchemy queries.

Who it is for

This skill is designed for developers and technical teams utilizing AI coding agents such as Claude Code, Cursor, and Codex to enhance their database interaction capabilities specifically within SQLAlchemy's 2.0+ asynchronous framework.

Use cases

• Developing complex AI-driven applications requiring efficient asynchronous database interaction.
• Optimizing database models and queries in AI agent-supported projects using PostgreSQL.
• Supporting migration and refactoring of existing codebases to align with SQLAlchemy 2.0+ async standards.

Technical details

• Requires Python ≥ 3.11 and the installation of `sqlalchemy[asyncio]` for integration with AI agents.
• Advises naming the driver explicitly in the connection URL, either `postgresql+asyncpg://` or `postgresql+psycopg://`.
• Follows a project-agnostic approach with generic example usage for seamless adaptation to specific projects.
