SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps design, implement, review, and debug production FastAPI services with strong attention to validation, authentication, async I/O, persistence boundaries, and API contracts.

Core Features & Use Cases

Endpoint design and review: Shape routes, request and response models, status codes, and error handling for clear REST contracts.
Production implementation guidance: Work with FastAPI dependencies, Pydantic models, SQLAlchemy sessions, lifespan resources, and async-first I/O patterns.
Diagnosis and performance tuning: Investigate failures, blocking operations, N+1 queries, lazy loading issues, transaction scope problems, and response bottlenecks.
Use case: Review a FastAPI endpoint before release to verify authorization, OpenAPI accuracy, rollback behavior, and test coverage.

Quick Start

Ask for a FastAPI implementation, review, or debugging plan for your route, schema, database, or async performance issue.

FAQPage Schema

How do I fix N+1 queries and lazy loading issues in FastAPI with SQLAlchemy?▼

Design FastAPI endpoints with explicit request and response models, stable HTTP error mapping, and clear REST contracts. This Skill reviews routes, status codes, and error handling for production readiness.

How do I implement async-safe authentication and dependency injection in FastAPI?▼

Implement async-safe authentication and dependency injection in FastAPI using explicit contracts and async-first I/O patterns. This Skill guides production implementation with lifespan resources and stable authorization verification.

Does FastAPI work with Pydantic validation and OpenAPI contracts for API reviews?▼

Pydantic models and OpenAPI contracts in FastAPI require explicit validation schemas and stable HTTP error mapping. This Skill reviews API contracts and verifies OpenAPI output accuracy for production services.

Why does my FastAPI async I/O operation block the event loop?▼

FastAPI async I/O operations block the event loop when synchronous database calls or improper transaction scopes occur. This Skill diagnoses blocking operations and performance bottlenecks in async-first request lifecycle handling.

What is the best way to structure FastAPI request lifecycle handling and error mapping?▼

The best way to structure FastAPI request lifecycle handling and error mapping is through explicit contracts, async-safe resource management, and stable HTTP error mapping. This Skill shapes routes and verifies error handling through tests and OpenAPI output.

Can I use FastAPI with SQLAlchemy sessions and async I/O for production services?▼

FastAPI supports SQLAlchemy sessions and async I/O for production services through async-safe resource management and explicit persistence boundaries. This Skill implements database session handling and reviews transaction scope for production readiness.
