Dinocheck

Your vibe coding companion - LLM-powered code critic

Dinocheck is an AI-powered code critic designed to enhance your vibe coding sessions. It's not a traditional linter - those focus on syntax and style. Dinocheck uses GPT, Claude, or local models to understand your code semantically and provide intelligent feedback on the things that matter: logic bugs, security issues, and architectural problems.

 src/views.py
------------------------------------------------------------

  [MAJOR] N+1 query detected in order iteration
     Rule: django/n-plus-one

     Why: Iterating over `Order.objects.filter(user=user)` and accessing
     `order.items.all()` inside the loop causes one query per order.

     Actions:
       • Use `prefetch_related('items')` to fetch all items in a single query.

  ----------------------------------------

  [CRITICAL] Missing permission check in delete_account view
     Rule: django/api-authorization

     Why: The `delete_account` view modifies user data but has no permission
     check. Any authenticated user could delete any account by guessing the ID.

     Actions:
       • Add ownership validation: `if account.user != request.user: return 403`
       • Consider using DRF's permission classes for consistent access control.

Why Dinocheck?

Traditional linters catch syntax errors and style issues. Dinocheck catches logic bugs, security issues, and architectural problems that only an AI can understand:

• Detects N+1 queries that would kill your database
• Spots missing authorization checks before they become CVEs
• Finds race conditions in your async code
• Identifies test mocks that hide real bugs

Philosophy

Dinocheck is a linter, not a fixer. It's designed to be your coding companion:

• Reviews your code with LLM intelligence
• Points out issues and explains why they matter
• Lets you decide how to fix them

This fits the vibe coding workflow: you write code with AI assistance, and Dinocheck provides a second opinion.
