CodeCouncil — Multi-Agent PR Review System

Built for the Global AI Hackathon with Qwen Cloud (Track 3: Agent Society)

What is CodeCouncil?

CodeCouncil is a multi-agent PR review system where 4 specialized AI agents debate pull requests and produce a consensus verdict.

Architecture

Agents

• 🔴 SecurityAuditor — finds vulnerabilities, SQL injection, hardcoded secrets
• 🟡 PerfEngineer — detects N+1 queries, complexity issues, memory leaks
• 🟢 CleanCodeReviewer — enforces naming, SOLID principles, code quality
• 🟣 TechLead — reads the full debate and makes the final verdict

How it works

1. PR opened on GitHub → webhook fires
2. All 3 specialist agents analyze independently (Round 1)
3. Agents read each other's opinions and debate (Round 2)
4. TechLead arbitrates and posts verdict to GitHub PR (Round 3)
