Claude Code can add auth to your FastAPI route…

…but it might still leave this bug:

order = await db.get(Order, order_id)

That means any logged-in user can fetch another user's order if they know the ID.

My FastAPI Claude Code kit forces Claude to check ownership scoping:

select(Order).where(

Order.id == order_id,

Order.account_id == current_user.account_id

)

I built 10 Claude Code commands for junior FastAPI devs:

- add auth safely

- review routes

- catch SQLAlchemy async bugs

- generate runnable tests

- audit production readiness

I've been writing system prompts for Claude Code for months and testing them across dozens of real projects. Here are the 3 mistakes I see developers make constantly:

1. Being too vague with context

"You are a helpful coding assistant" tells Claude nothing. Instead, specify the stack, the project structure, and the coding conventions you follow. The more specific your context window, the fewer corrections you'll make downstream.

2. Not setting output constraints

Without constraints, Claude will give you a 200-line function when you needed 20. Define max file sizes, preferred patterns (composition over inheritance, functional over OOP, etc.), and whether you want tests included by default.

3. Forgetting to specify error handling patterns

Every team handles errors differently. If you don't tell Claude whether to use try/catch, Result types, or error boundaries, you'll spend half your time refactoring the error flow.

I built a full prompt pack that solves all three — battle-tested templates for scaffolding, debugging, refactoring, testing, and more. Each one is plug-and-play with Claude Code.

You're in. Here's how to get the most out of your prompt pack:

1. Download the templates → Head to the "Prompt Files" tab to grab the full collection.

2. How to use them → Each prompt file includes instructions at the top. Copy the system prompt into your Claude Code config (CLAUDE.md or CLI flags) and you're good to go.

3. Request prompts → Drop a message in the Community chat if there's a specific workflow you need a prompt for. I'm actively building new ones based on member requests.

4. Stay updated → I'll post new prompts and updates right here in this feed. You'll get notified automatically.

Let's ship some code.
