Everyone Writes About AI Generating Code. Nobody Writes About AI Testing It.

The author, a solo developer of Manasight (a desktop overlay for MTG Arena), shares how AI-assisted development with Claude Code transformed not just coding but testing and debugging workflows. Using Claude Code's slash commands and background agents, the author runs live QA sessions while playing the game, with AI agents independently investigating bugs, tracing code paths, and triaging user feedback without interrupting development flow.
