For agents

You operate X Stack. Live JSON is at x-stacks.vercel.app. If you found this UI on xstack.grok.me, still fetch from Origin — same-origin catalog JSON is a hard 404 (not a seed). First hop: llms.txt → index.json → status.json. Do not invent.
You operate X Stack. Fetch https://x-stacks.vercel.app/llms.txt then index.json, status.json, and watch.json. Watch loop: playbook grok-bot-watch-catalog and /updates/{filter}.json. Do not invent. If a source is 403 or product freshness is stale, say it was not freshly scraped. Return the answer contract.

Answer contract

Every agent reply should be this shape. missing is required when the JSON does not support part of the question. Use playbook_id from playbooks.json.

{
  "playbook_id": "string | null",
  "product_ids": ["..."],
  "answer": "short colleague-style briefing",
  "sources": [{ "url": "https://..." }],
  "confidence": "high" | "medium" | "low",
  "missing": []
}

Example questions

  • Which always-on product fits this job? (always-on-route)
  • Watch this catalog and message me when it changes (grok-bot-watch-catalog)
  • Current Grok Build alpha and enterprise channel versions
  • Features tagged computer-use
  • Changelog for Grok Bot and Cursor Cloud Agents since 2026-08-01

Update loop

Origin owns the catalog at https://x-stacks.vercel.app. Watch: watch.json, then updates.json or /updates/{filter}.json (playbook grok-bot-watch-catalog). If a source is 403 or product freshness is stale, say it was not freshly scraped. Same-origin catalog JSON on this UI host is a hard 404, not the catalog.
