Developer builds VS Code extension to map AI agent code changes

A developer has created a VS Code extension called Contour MCP to address the problem of AI coding agents and human developers breaking system contracts due to a lack of visibility into code interdependencies. Contour MCP builds a live map of a codebase's actual call chains, going beyond documentation or old diagrams to reflect the current state of the code. It provides inline annotations within the editor, showing how many frontend calls hit a specific backend endpoint or which backend method handles a frontend request, enabling developers to easily trace and understand complex system interactions.

IMPACT Enables developers to better manage AI-generated code changes and maintain system integrity.

    I Got Tired of AI Agents Breaking My System Contracts, So I Built Something to Stop It

    <p>Okay, story time.</p> <p>If you've worked on a full stack app where the backend is Java/Spring Boot and the frontend is React, you know the drill. Someone changes something on one side of a contract and nobody tells the other side. Weeks later you're playing detective across f…
