We Built an AI Agent That Intentionally Breaks Code to Fix It Before Hackers Do
We just wrapped up our submission for the IBM Bob 2.0 Hackathon ! Our team, Syntax and Synergy , built Resilix —an autonomous adversarial agent that tests code resilience and auto-generates defensive security patches before code hits production. 🚨 The Problem Developers and AI models are writing code faster than ever. However, security testing tools are often built for slow, late-stage pipeline…
The IBM Bob 2.0 Hackathon concluded with the team Syntax and Synergy presenting their innovative creation, Resilix. This autonomous adversarial agent is designed to test the resilience of code and generate defensive security patches before the code is deployed in production. The rapid pace of development often results in security testing tools being used primarily in late-stage pipeline audits rather than during the active development process.
Vulnerabilities such as unhandled null pointers, string overflows, and SQL injections frequently go unnoticed due to these edge cases.
Resilix operates as a real-time defensive assistant, employing multi-vector payload fuzzing to analyze code against SQL injections, null pointer exceptions, buffer overflows, and malformed structures. It calculates an instant safety score on a 0-100 scale by assigning severity weights to potential issues. The agent is capable of generating copy-pasteable fixed code snippets alongside detailed risk breakdowns.
Additionally, it features a user-friendly Chaos Dashboard, a clean dark-mode web interface for instant local testing.
The entire application was developed within the IBM Bob 2.0 environment, which provided a structured plan mode for designing the microservice architecture, API endpoints (such as /api/fuzz), and scoring formulas. The agent mode facilitated the generation of Flask server logic (app.py) and the interactive single-page user interface (index.html). The project maintained consistency across .bob/rules-* files and tracked all execution logs in bob_sessions/.
