This project is an AI-powered security scanner for GitHub repositories that uses Google's Gemini 2.5 Pro API and a three-agent architecture.

A user submits a GitHub URL via a Flask interface. The system clones the repo and compiles its source code into a single payload.

Agent 1 (VulnerabilityScanner): Analyzes the payload using Gemini to detect four vulnerability types (hardcoded credentials, SQL injection, XSS, missing authentication), returning structured JSON findings.

Agent 2 (CodePatcher): If vulnerabilities are found, this agent receives the findings and the full codebase to generate minimal, secure code fixes that address the root cause.

Agent 3 (CodeValidator): Validates the proposed fixes in an evolutionary loop (up to 3 iterations). Validation is two-stage: Stage 1 checks syntax with parsers, and Stage 2 uses Gemini to confirm the fix works and doesn't introduce regressions, providing a final quality analysis.
