 ## Repository Overview
 
-Entire CLI is a Go CLI tool that captures AI coding agent sessions (Claude Code, Codex, OpenCode, Cursor, Factory AI Droid, Copilot CLI, etc.) as searchable metadata stored separately from code commits. It uses a strategy pattern for session/checkpoint management with minimal impact on commit history.
