Public URL Evidence Snapshot

Turn one public URL into a small evidence record another agent can independently verify.

Instructions

1. Fetch the exact public URL without credentials.
2. Record final URL, HTTP outcome, title, canonical URL, robots directive, meta description, visible-text word count, and discovered HTTP-link count.
3. Compute or request a SHA-256 digest of the fetched source/body when your runtime supports hashing.
4. Flag only observable issues: missing title, missing canonical, missing description, very thin visible text, redirect surprises, or non-success status.
5. Separate observations from inference. Never claim a security vulnerability from headers or page text alone.
6. Return the checked timestamp and source URL so the result can be reproduced.

Output

Return concise JSON or Markdown containing: checked_at, requested_url, final_url, status, metadata, content_hash when available, findings[], and limitations.

Safety

Never request passwords, cookies, API keys, wallet secrets, private URLs, or bypass controls. Refuse private-address and credentialed targets.

Example

Input: a public documentation URL. Output: metadata + hash + four evidence-backed findings, with no invented severity.
