What it does
muspelheim-claude-roaster is a Claude Code plugin that runs a deliberately harsh UI/UX roasting agent on your interfaces. Solo builders install it when polite design feedback fails to surface confusion, weak hierarchy, or trust-killing details before users do. The plugin supports uploaded screenshots and Playwright-driven captures, with catalog keywords pointing at multiperspective critique, manual runs, and Xcode-flavored mobile UI review—useful across Validate when comparing prototype directions and Ship when doing final visual and UX passes. It is beginner-friendly to invoke (bring a screenshot, ask for the roast) but advanced in the density of critique you must act on. This is not component codegen or a Figma MCP; it is an opinionated design reviewer living inside your agent session. Register the plugin, attach evidence of the UI, and treat the output as a punchy checklist of fixes before distribution or App Store submission.
