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.

Developers and AI models are writing code faster than ever. However, security testing tools are often built for slow, late-stage pipeline audits rather than active development. Unhandled null pointers, string overflows, and SQL injections frequently slip through under hostile edge cases.

Resilix acts as a real-time defensive assistant:

The entire application was built inside the IBM Bob 2.0 environment:

`/api/fuzz`), and scoring formulas.` app.py`) and single-page interactive UI (` index.html`).`.bob/rules-*` and tracked all execution logs in `bob_sessions/`.
We'd love to hear your thoughts and feedback from the DEV community! 🚀
