 ## Project Overview
 
-agentsview is a local web viewer for AI agent sessions (Claude Code, Codex, Copilot CLI, Gemini CLI, OpenCode). It syncs session data from disk into SQLite (with FTS5 full-text search), serves a Svelte 5 SPA via an embedded Go HTTP server, and provides real-time updates via SSE.
