Crabbox
A "local loop, remote box" validation tool: keep your editor and git workflow locally, but rsync your dirty checkout to a leased remote machine, run the full suite there, and stream results back — distributed as the
crabboxskill inopenclaw/agent-skills.
What it does
Crabbox solves the "my laptop can't (or shouldn't) run the whole suite" problem for agent and human workflows alike. You keep editing locally; Crabbox leases a remote box, rsyncs your dirty checkout (uncommitted changes included), runs the validation there, and streams the run back to your terminal.

| Capability | Detail |
|---|---|
| Local loop, remote box | Editor + git stay local; the run executes on a leased remote machine and streams back. |
| Brokered, not BYO creds | A Cloudflare Worker holds provider credentials and serializes lease state; your CLI only carries a bearer token. |
| Cost-aware leases | TTL-bounded machines, monthly spend caps, and per-user / per-org / per-provider usage from the broker. |
| Reuse what's warm | crabbox warmup keeps a box hot; reuse it with --id across runs, SSH, and CI hydration. |
| Many providers, one loop | Brokered Hetzner / AWS / Azure, delegated E2B / Daytona / Blacksmith / Semaphore, or static SSH targets behind one interface. |
| GitHub Actions hydration | actions hydrate reuses a repository's GitHub Actions setup so local runs land in a CI-like workspace. |
| Remote desktop | crabbox webvnc streams a Linux, macOS, or Windows desktop into the browser for UI tests, screenshots, and handoff. |

Where it fits Kevin's stack
Crabbox is the remote-validation complement to Security and Review Skills (pre-merge review): autoreview reads the diff and finds edge cases; Crabbox proves the change in a CI-parity environment with broad system access. Peter Steinberger runs both as his core stack. Source: X/@steipete, 2026-05-27 Conceptually it belongs in the Agent Sandboxes / Persistent Sandbox Thesis cluster (warm, reusable, TTL-bounded remote environments) and overlaps in spirit with Browser Testing Skills and Modal Labs for ephemeral compute — but optimized for the "validate my local diff somewhere bigger" loop rather than for hosting an agent.
Adoption caveat: it lives in the OpenClaw ecosystem, which has a documented community-skill malware history — run the three-gate chain (Brin → skill-auditor → reputation) before installing, per AGENTS.md. Source: compiled from wiki, 2026-06-12
