SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Deleted or altered GitHub content can be difficult to reconstruct; important artifacts like README files, issues, PRs, wiki pages, and repository metadata may persist only in web archives. This skill provides a structured workflow to locate, access, and extract archived content from the Wayback Machine and Archive.org using CDX API queries to support investigations, audits, and historical analysis.

Core Features & Use Cases

  • Archive discovery: identify snapshots of GitHub pages (README, issues, PRs, wiki, metadata) in web archives.
  • Recovery workflow: construct archive URLs, fetch archived content, and present it for documentation or incident response.
  • Use Case: perform post-incident analysis by retrieving archived issues and release notes from deleted repositories.

Quick Start

Retrieve archived content by querying Wayback/Archive.org for a given GitHub URL and extracting the latest accessible snapshot.
