Sweep

Skill uprockcom/uprock-claude-plugin/skills/sweep

Test a URL's uptime, reliability, and performance from real devices across geographic regions. Use when the user wants to check if a site is up, how fast it loads worldwide, Core Web Vitals, or to verify a deployment from different regions.From its SKILL.md

UpRock: Sweep (global uptime & performance)

Load a URL from real devices in multiple regions at once and report reliability + performance. Great right after a deploy, or to see how a site performs for users around the world.

How to do it

  1. Call the uprock MCP tool sweep with:

    • url: target URL (required).
    • regions: subset of NA, EU, APAC, LATAM, MEA. Default [NA, EU, APAC] (fastest, most reliable pools). Add LATAM/MEA when the user cares about those markets.
    • device: mobile (default) or desktop.
    • tries: checks per region (default 5). All checks run concurrently.
    • timeout: overall seconds (default 60); total wall-clock ≈ this value.
  2. Each completed check returns Core Web Vitals (TTFB, FCP, LCP, CLS), load time, transfer size, and HTTP protocol. The response includes a report_url (shareable human-readable report) and screenshots as sweep:// resource URIs.

  3. Summarize for the user:

    • Up/down per region and the failed_jobs count (inspect per-job error fields for failures).
    • Performance per region (highlight slowest regions / poor LCP or CLS).
    • Share the report_url.
    • If they want to see a region's render, call resource_fetch on a sweep://…/screenshot URI.

Notes

  • A sweep can partially succeed; always report how many checks failed and why.
  • For reading a page's content (not measuring it), use /uprock:scrape.
