FlakeStorm: Chaos Engineering for AI Agent Testing
Read Full Article: FlakeStorm: Chaos Engineering for AI Agent Testing![[P] FlakeStorm: Chaos Engineering for AI Agent Testing (Apache 2.0, Rust-accelerated)](https://www.tweakedgeek.com/wp-content/uploads/2026/01/featured-article-8197-300x171.png)
FlakeStorm is an open-source testing engine designed to enhance AI agent testing by incorporating chaos engineering principles. It addresses the limitations of current testing methods, which often overlook non-deterministic behaviors and system-level failures, by introducing chaos injection as a primary testing strategy. The engine generates semantic mutations across various categories such as paraphrasing, noise, tone shifts, and adversarial inputs to test AI agents' robustness under adversarial and edge case conditions. FlakeStorm's architecture complements existing testing tools, offering a comprehensive approach to AI agent reliability and security, and is built with Python for compatibility, with optional Rust extensions for performance improvements. This matters because it provides a more thorough testing framework for AI agents, ensuring they perform reliably even under unpredictable conditions.

VidaiMock: Local Mock Server for LLM APIs
Read Full Article: VidaiMock: Local Mock Server for LLM APIs
VidaiMock is a newly open-sourced local-first mock server designed to emulate the precise wire-format and latency of major LLM API providers, allowing developers to test streaming UIs and SDK resilience without incurring API costs. Unlike traditional mock servers that return static JSON, VidaiMock provides physics-accurate streaming by simulating the exact network protocols and per-token timing of providers like OpenAI and Anthropic. With features like chaos engineering for testing retry logic and dynamic response generation through Tera templates, VidaiMock offers a versatile and high-performance solution for developers needing realistic mock infrastructure. Built in Rust, it is easy to deploy with no external dependencies, making it accessible for developers to catch streaming bugs before they reach production. Why this matters: VidaiMock provides a cost-effective and realistic testing environment for developers working with LLM APIs, helping to ensure robust and reliable application performance in production.
