What problem does it solve? Running broad OpenClaw test gates, CI-parity checks, and end-to-end bug verification locally is slow and unreliable. This Skill routes remote validation through the Crabbox wrapper so tests execute on real Linux, macOS, Windows, or WSL2 environments with correct provider attribution. ## Core Features & Use Cases - Multi-provider remote execution: Run pnpm gates and E2E scenarios on brokered AWS Crabbox (cbx_... leases) or delegated Blacksmith Testbox (tbx_... ids), with static SSH targets for macOS and Windows hosts. - Observability and debugging: Use --timing-json, --preflight, --capture-on-fail, --full-resync, and phase markers to diagnose sync, hydration, and test failures. - Interactive proof: Drive desktop/WebVNC sessions and tmux-based CLI onboarding flows for human QA handoff. - Use Case: A maintainer fixes a Docker install bug, then runs one Crabbox E2E command from the user-facing entrypoint to prove the broken state before the fix and the passing state after, recording the Testbox id and redacted output. ## Quick Start Ask the assistant to run the changed-files test gate remotely via Crabbox with timing JSON enabled and report the actual provider and lease id.
