What problem does it solve? Web pages get deleted, edited, or quietly rewritten, and the live site only shows the current version. This Skill recovers prior versions of pages, enumerates every URL an archive ever captured for a domain, and preserves evidence before it disappears. ## Core Features & Use Cases - CDX API enumeration: Query the Wayback Machine's CDX index with matchType, filters, and collapse=digest to list every archived URL under a domain and pinpoint the exact dates content changed. - Multi-archive recovery: Fall back to archive.today for JavaScript-heavy pages, Common Crawl for independent coverage, and Memento aggregators for national archives when Wayback has nothing or shows an exclusion. - Evidence preservation and verification: Capture pages to hashed WARC files, submit to two independent archives, fetch raw captures with the id_ modifier, and grade findings with a confirmed/probable/unconfirmed confidence scale. - Use Case: A supplier claims an industry certification. You use collapse=digest on their certifications page, diff the raw captures either side of a change, and discover the accreditor's name was quietly swapped — with a dated, citable archive URL for each version. ## Quick Start Use the read-deleted-pages skill to find what example.com's team page said before it was edited last year and list every archived URL under the domain.
