If you're debugging Antithesis test runs, this skill walks Claude through using the multiverse debugger to inspect container filesystems, run shell commands, and extract evidence from failed test scenarios. It supports both the simplified command interface and the advanced JavaScript notebook mode, with detailed references for switching between them, authorizing actions, and navigating debugging sessions. The skill emphasizes starting with simplified mode for most tasks and only escalating to advanced when you need time travel to inspect crashed containers or complex multi-step workflows. Requires agent-browser to drive the web interface, and includes ready-to-use snippets for common inspection patterns.
