Developer Builds Zero-Dependency C++17 Security Scanner RepoShield for CI Pipelines

A developer has built RepoShield, a standalone C++17 command-line tool designed to analyze repository security without relying on third-party runtime libraries. The tool performs filesystem traversal, code structure extraction, dependency analysis, risk scoring, and policy enforcement within a single unified pipeline. RepoShield goes beyond flagging individual vulnerabilities by generating machine-readable reports and returning exit codes that can automatically fail CI pipelines when security policies are violated. Built under a strict zero-dependency constraint, the project uses only C++17 standard library features to handle tasks typically delegated to external packages. The tool was developed with the goal of answering practical security questions about a repository, including what risks exist, where they are located, how serious they are, and what remediation steps should follow.
