fastapi-domain-delivery

What problem does it solve?

It prevents unsafe or ambiguous FastAPI behavior changes by forcing a production-minded, typed delivery plan that keeps Pydantic contracts, async boundaries, dependency injection, lifespan resources, database session lifetimes, background-task durability, OpenAPI, and auth scopes consistent.

Core Features & Use Cases

• Typed FastAPI boundary planning: designs separate Pydantic models for request/response/internal needs and ensures OpenAPI matches enforcement-ready behavior.
• Dependency graph and lifecycle correctness: builds an explicit, acyclic dependency tree with correct cleanup using FastAPI lifespans and request-scoped resources.
• Async-safe persistence and background safety: specifies async SQLAlchemy session/transaction ownership and rejects request-session reuse in background work, including durable vs in-process job decisions.
• Verification-first delivery: requires targeted pytest and evidence capture, with defined rollback/repair loops when scoped checks fail.

Quick Start

Ask your AI to generate a FastAPI delivery plan for the specific router/path you are changing and to include scoped evidence and a rollback path.
