Muggle Works
Acceptance test agent for coding agents: real-browser tests, with screenshots on the PR.
Coding agents are good at producing a diff. They are bad at knowing whether the diff works, whether it broke the login flow, and what still has to happen before a human can merge it. Muggle Works is the harness around the agent that answers those questions: it freezes requirements, delegates the design and build, runs the unit suite, drives a real browser through the affected user flows, opens the pull request with screenshots attached, and then keeps watching that PR — picking up review comments, red CI, and a stale base branch until the change is genuinely mergeable.
Works in Claude Code, Cursor, Codex, Windsurf, and any MCP client. Powered by Muggle AI.
