Your AI assistant writes code fast. But does the feature actually work? Does the login flow break on mobile? Does the checkout still render after that refactor? muggle-ai-works closes the gap between "code complete" and "actually works." Catch UX regressions before your users do — AI drives a real browser against your localhost across desktop and mobile resolutions, clicks through flows like a user would, and reports failures with step-by-step screenshots. No Playwright scripts to maintain. Go from requirement to merged PR in one command — /muggle:muggle-do handles the full cycle: code the feature, run unit tests, run E2E acceptance tests against the app in a real browser at multiple viewports, triage failures, and open a PR with evidence attached. 70+ MCP tools for custom workflows — manage projects, generate test cases from plain English, replay test scripts, batch-run regressions, and publish results to your team. Works in Claude Code, Cursor, and any MCP client.
