The system discovers, triages, exploits, patches, and reports vulnerabilities in real open-source software with zero false positives by design. NEXUS features a governance council for severity scoring and a three-tier memory engine for learning across codebases.", "body_md": "Security auditing is broken.\n\nIf you’ve ever run a static analysis tool (SAST) on a large codebase, you know the pain: thousands of alerts, zero context, and a 90% false-positive rate. On the other end of the spectrum, hiring human penetration testers is incredibly expensive and impossible to scale alongside modern CI/CD pipelines.\n\nFor the **Qwen Cloud Global AI Hackathon**, we decided to rethink the problem entirely. What if, instead of using a single monolithic AI to \"find bugs,\" we built an entire specialized *civilization* of agents?\n\nMeet **NEXUS**, an autonomous society of 10 distinct AI agents that discovers, triages, exploits, patches, and reports security vulnerabilities in real open-source software.\n\nInstead of asking an LLM to \"find a bug and fix it\" (which usually results in hallucinations), we split the vulnerability lifecycle into 10 distinct, highly-specialized roles.\n\nPowered by the **DashScope API** (using `Qwen-Max`\n\nand `Qwen-Plus`\n\n), our pipeline looks like this:\n\n`Qwen-Plus`\n\n):`Qwen-Plus`\n\n):`Qwen-Max`\n\n):`Qwen-Max`\n\n):`Qwen-Max`\n\n):`Qwen-Max`\n\n):`Qwen-Max`\n\n):`Qwen-Plus`\n\n):By forcing the system to generate a PoC and independently verify it, we shifted from a model of *guessing* bugs to *proving* them. **Zero false positives by design.**\n\nOne of the coolest features we built is the **Governance Council**.\n\nWhen the Hunter agent finds a verified vulnerability, we don't just ask a single LLM to rate its severity. Instead, we spin up three distinct agents with completely different system prompts:\n\nThese three agents independently evaluate the finding, and the orchestrator mathematically averages their scores to reach a consensus. Watching them debate a vulnerability in real-time on our dashboard feels like a glimpse into the future of autonomous organizations.\n\nTo make NEXUS actually *learn* from its scans, we couldn't just rely on context windows. We built a 3-tier memory engine:\n\n`pgvector`\n\n):`pgvector`\n\n. Over time, NEXUS actively learns what vulnerabilities \"look\" like across different codebases.NEXUS isn't just an API wrapper; it's deeply integrated into the Alibaba Cloud ecosystem.\n\n`dashscope-intl.aliyuncs.com`\n\nAPI for Qwen inference. We routed high-reasoning tasks to `Qwen-Max`\n\nand summarization/routing tasks to `Qwen-Plus`\n\nto optimize our API credits.`oss2`\n\nPython SDK so that the moment the Report agent finishes its job, the final Markdown advisory is immutably uploaded to We built a Next.js \"Mission Control\" dashboard that connects to our backend via WebSockets. When you paste a GitHub URL into NEXUS, you get to sit back and watch 10 AI agents systematically dismantle, exploit, and patch the codebase in real-time.\n\nBuilding NEXUS taught us that the future of AI isn't a single, omniscient chatbot. It's specialized, communicative, and governed societies of agents working together to solve problems that humans simply don't have the scale to tackle alone.\n\n*Built for the Qwen Cloud Global AI Hackathon 2026.
