New CLI: openclaw plugins build, validate, init. Ships gateway cost attribution, overlapped startup logging, Docker build arg, minimum Node.js 22.19.

Product Idea from this Signal

A CLI tool that validates, tests, and dry-runs OpenClaw plugins in an isolated sandbox before publishing to ClawHub

372.1k โ–ฒ

OpenClaw's plugin ecosystem ships broken packages to production. The Brave plugin v2026.5.2 went live with only TypeScript source and no compiled dist/, crashing every gateway that installed it into an unrecoverable 1.2-second restart loop. Four separate GitHub issues filed for the same root cause. The new defineToolPlugin SDK (v2026.5.18) gives plugin authors a typed API, but there is no validation step between writing a plugin and publishing it to ClawHub where 44,000+ skills live. This tool runs a full lifecycle check in an isolated container: schema validation, build verification, dependency audit, gateway integration test, and provider registration smoke test. It catches the exact class of bugs that took down Brave search users.
