feed-validate

name	feed-validate
description	Check a single RSS/Atom feed URL for liveness, staleness, redirects, and label accuracy. Use this atom when feed-curator needs to verify individual feed health or when any monitoring system needs a per-URL health check. Do NOT use for feed discovery — that is atom-feed-discover. Do NOT use for content extraction from feeds.

feed-validate

Validates a single feed URL and returns its health status (live, dead, stale, redirect). Used by feed-curator to check each feed individually and by any system maintaining a feed catalog.

Input

{
  "feed_url": "https://www.fldoe.org/feed.xml",
  "label": {"category": "standards", "authority": "primary"},
  "last_check_date": "2026-06-15",
  "check_types": ["liveness", "staleness", "redirect"]
}

Output

{
  "tool": "feed-validate",
  "status": "live",
  "http_code": 200,
  "reason": "Feed updated 2 hours ago; last 5 entries recent",
  "redirect_target": null,
  "last_entry_date": "2026-06-27T10:30:00Z",
  "confidence": "high",
  "label_issues": [],
  "human_review_required": true

Do NOT use this atom for

• Feed discovery from a seed page (use atom-feed-discover)
• Content extraction or summarization from feeds
• Bulk feed validation (call this atom once per feed URL)

Pipeline note

Follows references/method.md at the Validation step (feed health check). Output conforms to protocol-layer/metadata-schema.md. human_review_required: true — feed health is advisory; dead feeds may be temporarily unreachable.
