Test it

Using "fastapi-templates". Plan a FastAPI user service template with async patterns

Expected outcome:

  • Folder layout for api, core, models, schemas, services, repositories
  • Async database session dependency and application lifespan flow
  • User repository and service responsibilities
  • Endpoints and test setup overview

Using "fastapi-templates". How do I set up dependency injection for database sessions?

Expected outcome:

  • Use AsyncSessionLocal from SQLAlchemy with sessionmaker
  • Create get_db async generator dependency with try/except/finally
  • Override dependency in tests with test database session
  • Commit on success, rollback on exception

Security Audit

Safe
v4 • 1/17/2026

This is a documentation-only skill containing architectural guidance and code examples for FastAPI projects. All 41 static findings are FALSE POSITIVES: cryptographic algorithms (bcrypt, HS256) shown are industry-standard secure choices; backtick patterns are markdown code delimiters, not shell execution; environment variable references are Pydantic configuration definitions, not secret access. The skill has no executable code, network calls, or filesystem access capabilities.

What You Can Build

New API baseline

Define a FastAPI structure with async, dependency injection, and testing patterns for a new service.

MVP API setup

Get a clear project layout and core patterns for a first FastAPI MVP.

Team architecture guide

Standardize repository and service layer patterns across multiple APIs.

Try These Prompts

Starter structure 
Provide a clean FastAPI folder structure with brief notes for each folder and file purpose.
Async DB setup 
Show a minimal async database session setup with dependency injection and safe commit handling.
Repository and service 
Draft a base repository pattern for async CRUD and a user service layer that uses it.
JWT auth and tests 
Outline a JWT authentication flow and a minimal async test strategy for the user endpoints.

Best Practices

  • Keep async across routes, database, and background tasks
  • Separate routes, services, and repositories for clarity
  • Use Pydantic schemas for consistent request and response data

Avoid

  • Put business logic inside route handlers
  • Use blocking database drivers in async routes
  • Skip tests for core user flows

Frequently Asked Questions

Is it compatible with current FastAPI versions?
Yes, the patterns are framework level and align with current FastAPI practices.
What are the limits of this skill?
It provides guidance and examples, not automatic project generation.
Can I integrate it into an existing project?
Yes, adopt the patterns module by module.
Does it access my data or secrets?
No, it is documentation only and performs no data access.
What if my async setup fails?
Check database URL, driver support, and event loop configuration.
How does it compare to a code generator?
It gives architectural guidance instead of creating files.
