By adding deterministic AST and path sandboxing validation gates outside the LLM before code commits, the team reduced adversarial commits from 21 to 0.", "body_md": "When building autonomous AI coding agents, standard system prompts aren't enough. We've all seen the headlines about AI agents breaking out of sandboxes, altering CI/CD pipelines, or executing prompt injections hidden inside code comments.\n\nInstead of guessing whether our agent was safe, we built an automated Adversarial Red-Teaming Benchmark to stress-test our agent architecture against prompt injections and scope escapes.\n\nHere is the exact data from our evaluation pipeline, how we swapped LLM personas to simulate a compromised model, and how we reduced adversarial commits from 21 down to 0.\n\nThe Attack Vectors We Tested\n\nTo reflect real-world repository hazards, we categorized our test cases into two main security concerns:\n\nThe Vulnerability: When the LLM was replaced with the scopeEscape persona, it successfully committed unauthorized changes 21 times (e.g., escaping into sibling modules and build scripts). Relying on the model to \"know its boundaries\" failed miserably.\n\nIteration 2: Deterministic AST & Path Sandboxing\n\nWe implemented hard, non-LLM validation gates prior to code commit:\n\nKey
