    Senior-level defensive security auditing and remediation for vibe-coded and AI-assisted software projects. Use AgentSec to understand a repository efficiently, review application and server security, identify vulnerable or malicious dependencies, reason about architecture and least privilege, propose secure code rewrites, apply safe fixes, and verify the result with current security intelligence and deterministic tools.
