A guide for SQLSpec, a Python library that maps SQL queries to application code without being an object-relational mapper, or ORM.

Use it for named SQL, filters, pagination, query drivers, data dictionaries, observers, and integrations with Litestar, FastAPI, Flask, Starlette, or Sanic.

It helps applications use raw SQL, query builders, or SQL files through consistent database connections, validation, parameters, and database-dialect conversion.

Install

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Clone the repo

git clone --depth 1 https://github.com/litestar-org/litestar-skills

agentmods

npx agentmods add skills/litestar-org/litestar-skills/sqlspec

Made for: Claude Code.

Or install litestar, the plugin that ships this one along with the rest of its 20 skills, 1 agent, 1 hook.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00051	$0.04245
Opus 5.5	$0.00020	$0.01698

Security

Grade A, and why

sqlspec scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 330 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SQLSpec Skill

SQLSpec is a type-safe SQL query mapper for Python -- NOT an ORM. It provides flexible connectivity with consistent interfaces across 20 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.

Code Style Rules

from __future__ import annotations rule — SQLSpec adapter config modules and driver definitions avoid from __future__ import annotations because configs are introspected at runtime. Consumer application modules (handlers, services, tests that use a configured driver) MAY and typically SHOULD use it — canonical Litestar apps use it in 100+ files.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

sqlspec is a skill published in the GitHub repository litestar-org/litestar-skills (16 stars, last pushed 2d ago), licensed MIT. It adds 51 tokens to every session and 4,245 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
