SQLSpec Skill

SQLSpec is a type-safe SQL query mapper for Python -- NOT an ORM. It provides flexible connectivity with consistent interfaces across 19 database adapter packages. Write raw SQL, use the builder API, or load SQL from files. Statements pass through a sqlglot-powered AST pipeline for validation, parameter handling, and dialect conversion.

Match-Your-Framework — read first

sqlspec ships first-party extensions for five web frameworks. If your project uses one of these, jump directly to the matching integration guide and skip the others:

• Litestar — register configs on SQLSpec, then pass that registry to SQLSpecPlugin. The plugin adds DI, the litestar db CLI, and request observability. See references/extensions.md.
• FastAPI → references/fastapi-integration.md — Depends(plugin.provide_session()) DI, Annotated[...] handlers, filter providers.
• Flask → references/flask-integration.md — plugin.init_app(app), pull-based plugin.get_session(), async-via-portal.
• Starlette → references/starlette-integration.md — request.state-based session access, lifespan wrapping, middleware variants.
• Sanic — first-party ASGI-style extension for Sanic applications; match Sanic's app/request lifecycle instead of copying Litestar DI examples.

Shared topics that apply to every framework live in references/commit-modes.md (autocommit / manual middleware) and references/multi-database.md (multi-config registry). Read the framework guide first, then those for depth.

The rest of this SKILL.md covers framework-agnostic topics: adapter setup, query builder, driver methods, filters, observability, migrations, the ADK extension, and data-dictionary introspection.
