: I Built an AI That Scans Repos, Screens Candidates, and Agents Inside VS Code — As a 2nd Year CS Student

Let me tell you about the three problems that made me build this.

First — every time a developer joins a new project, they spend days just trying to understand what they're looking at. No one has time to write good documentation, and no one has time to read bad documentation. Second — hiring managers are drowning in CVs where everyone claims to know React, Python, and "machine learning," but nobody can tell who actually writes real code versus who just copies tutorials. Third — AI coding assistants are powerful, but they live in a browser tab while your actual work lives in VS Code. You're constantly context-switching between the tool and the work.

I got tired of all three. So I built RepoLens.

What RepoLens Actually Is

RepoLens started as a GitHub repository scanner. It's now something significantly bigger — an AI system that onboards developers into codebases, screens technical candidates by reading their actual commit history, and operates as a VS Code agent that can open files, edit code, and run terminal commands on your behalf. Three distinct capabilities. One product. Built by one second-year CS student from the University of Debrecen, in his own time, with no team and no budget.
