+# Project Summary: Copybuffer - Smart Clipboard Manager
+
+## Overview
+Successfully implemented a complete Smart Clipboard Manager for Ubuntu using TypeScript/Node.js as requested. The application stores clipboard history in JSON files, provides search functionality, global hotkey support, and GitHub Gist sync capabilities.
+
+## Implementation Status: ✅ Complete
+
+### Core Features Implemented
+- ✅ **Clipboard Monitoring**: Automatic clipboard history tracking with configurable intervals
+- ✅ **JSON Storage**: All data stored in simple JSON files at `~/.copybuffer/`
+- ✅ **Search Functionality**: Full-text search with query limits and filters
+- ✅ **Global Hotkeys**: F9 for history, F10 for search (using node-global-key-listener)
+- ✅ **GitHub Gist Sync**: Two-way sync with private GitHub Gists
+- ✅ **CLI Interface**: 12 comprehensive commands for all operations
+- ✅ **Configuration Management**: JSON-based config with safe update mechanism
+
+### Technical Stack
+```
+TypeScript 5.3.0
+Node.js (18+)
+clipboardy: Clipboard access
+commander.js: CLI framework
+node-global-key-listener: Global hotkeys
+Native HTTPS: GitHub API integration
