## Summary

In an opinion piece, the author proposes a software quality assurance method called "ephemeral testing." Instead of assessing a software component or library directly, developers use an AI agent to build temporary, throwaway applications or layers on top of it. The agent then tests what it built.

The author argues that a high-quality library with a clean API and stable invariants allows an AI agent to quickly produce working software. Conversely, a poorly designed library with hidden states or incomplete documentation leads to failures. These failures serve as evidence of flaws in the underlying code rather than the agent's capabilities.

## Key points

- Ephemeral testing involves using an AI agent to build temporary applications on top of a software component to test its quality.
- A clean API and stable invariants allow the AI agent to produce working software quickly, while poor code leads to failures.
- The author uses this method to prototype features quickly and simulate how other software layers will interact with the core code.

## Why it matters

This approach introduces a new way for developers to leverage AI agents for integration testing, using rapid prototyping to evaluate code design and usability.
