+ +--- + +## The Problem + +**The "Happy Path" Fallacy**: Current AI development tools focus on getting an agent to work *once*. Developers tweak prompts until they get a correct answer, declare victory, and ship. + +**The Reality**: LLMs are non-deterministic. An agent that works on Monday with `temperature=0.7` might fail on Tuesday. Users don't follow "Happy Paths" — they make typos, they're aggressive, they lie, and they attempt prompt injections. + +**The Void**: +- **Observability Tools** (LangSmith) tell you *after* the agent failed in production +- **Eval Libraries** (RAGAS) focus on academic scores rather than system reliability +- **Missing Link**: A tool that actively *attacks* the agent to prove robustness before deployment + +## The Solution + +**Entropix** is a local-first testing engine that applies **Chaos Engineering** principles to AI Agents. + +Instead of running one test case, Entropix takes a single "Golden Prompt", generates 50+ adversarial mutations (semantic variations, noise injection, hostile tone, prompt injections), runs them in parallel against your agent, and calculates a **Robustness Score**. + +> **"If it passes Entropix, it won't break in Production."** + +## Features + +- **Semantic Mutations**: Paraphrasing, noise injection, tone shifts, prompt injections +- **Invariant Assertions**: Deterministic checks, semantic similarity, safety validations +- **Local-First**: Uses Ollama with Qwen Coder 3 8B for free, unlimited attacks +- **Beautiful Reports**: Interactive HTML reports with pass/fail matrices +- **CI/CD Ready**: GitHub Actions integration to block PRs below reliability thresholds + +## Quick Start + +### Installation + +```bash +pip install entropix +``` + +### Prerequisites + +Entropix uses [Ollama](https://ollama.ai) for local model inference: + +```bash +# Install Ollama (macOS/Linux) +curl -fsSL https://ollama.ai/install.sh | sh + +# Pull the default model +ollama pull qwen3:8b +``` + +### Initialize Configuration + +```bash +entropix init +``` + +This creates an `entropix.yaml` configuration file: + +```yaml +version: "1.0" + +agent: + endpoint: "http://localhost:8000/invoke" + type: "http" + timeout: 30000 + +model: + provider: "ollama" + name: "qwen3:8b" + base_url: "http://localhost:11434" + +mutations: + count: 20 + types: + -
