+## Executive Summary
+
+ColaFlow is a next-generation AI-powered project management system built on the Model Context Protocol (MCP). It aims to revolutionize team collaboration by making AI a first-class team member that can safely read, write, and manage project data while maintaining human oversight and control.
+
+### Vision Statement
+> "Flow your work, with AI in every loop."
+
+### Mission
+To create a platform where human-AI collaboration flows naturally, enabling AI to automatically generate and update tasks, documents, and progress reports while humans maintain decision-making authority through secure review and approval mechanisms.
+
+### Strategic Goals
+1. **AI-Native Project Management**: Enable AI tools to directly participate in project workflows
+2. **Seamless Integration**: Connect ChatGPT, Claude, GitHub, Calendar, Slack, and other tools through MCP
