Descriptions:
Web Dev Cody addresses a common pain point for developers leaning heavily on AI-assisted coding: as agents write more of the codebase, the developer’s own understanding of how things work can quietly erode. His proposed fix is deceptively simple — flip the interaction around and have the AI quiz you instead of building for you.
The technique involves prompting an agent (demonstrated here with what appears to be Claude Code) to conduct a one-question-at-a-time interview on a specific service, framework, or codebase. Cody walks through a live session where he’s being quizzed on his Mission Control Electron app — a system that connects a desktop app to remote sandboxed VMs via WebSocket. The session covers authentication via secret API keys, PTY session management with persistent session IDs, file I/O sandboxing through a file guard component, and HTTP endpoints used by Claude and Codex hooks.
One practical refinement shown mid-video: the initial prompt caused the agent to embed hints in its questions, so Cody updated it to include ‘do not lead the witness or give any hints.’ The technique is presented as especially useful during new project onboarding, language or framework transitions, and as a corrective for engineers who have drifted away from understanding codebases they nominally own. No special tooling or plugins are required — just a prompt.
