resource-preflight

Use before spending tokens, money or crawler capacity fetching an unfamiliar web resource.

Use before spending tokens, money or crawler capacity fetching an unfamiliar web resource. Resolves redirects (manually, bounded, re-validated per hop) and returns deterministic HTTP/resource facts — final URL, status, content type and length, response time, a bounded HTML title/canonical peek, and a lightweight generic-bot robots.txt indication — so an agent can decide whether a normal web fetch is worthwhile. It does not scrape, render JavaScript, or judge safety.
