SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill addresses the systematic blind spots that occur when an AI model writes and reviews its own code, specifically preventing regressions in sandbox and production environments.

Core Features & Use Cases

Sandbox-Mode API Testing: Enables fast, database-free testing of API routes to ensure consistency between development and production paths.
Regression Prevention: Provides a structured workflow to write tests specifically for bugs that have already been identified, ensuring they never recur.
Use Case: When an AI agent modifies backend logic, this skill guides the creation of tests that verify API response shapes and state management, catching common errors like missing SELECT clauses or broken sandbox parity.

Quick Start

Run the ai-regression-testing skill to initiate a bug-check workflow and generate regression tests for the identified issues.

FAQPage Schema

How do I prevent regression bugs when an AI agent modifies backend API routes?▼

To prevent regression bugs in AI-assisted development, you need automated regression testing that verifies API response shapes and state management logic. This involves writing structured tests validating API contracts and error handling paths.

How do I test sandbox and production API parity in web applications?▼

Testing sandbox and production API parity requires database-free testing of API routes to ensure consistency between development and production paths. Automated validation checks API response shapes and state management to catch common parity errors introduced during AI-assisted development.

What is the best way to write regression tests for recurring code defects?▼

The best way to write regression tests for recurring code defects is following a structured workflow that creates tests specifically for bugs that have already been identified. This ensures the same state management logic errors never recur when backend logic is modified.

Does automated API testing work with Vitest for error handling validation?▼

Automated API testing works with Vitest or similar testing frameworks to execute validation of API contracts and error handling paths. This setup enables fast, database-free testing of API routes to ensure consistency between development and production environments.

Can I run database-free testing for API route consistency in sandbox mode?▼

You can run database-free testing for API route consistency in sandbox mode to ensure development and production paths remain parallel. This fast testing method validates API response shapes and state management logic without requiring full database setup.
