An interactive self imporving AI coding agent for creating and using AI tools with Claude.At its core, Claude Engineer introduces a dynamic tool ecosystem where the AI can autonomously create, manage, and execute its own tools during conversations. This allows the system to continuously expand its capabilities, adapting to user needs in real time and becoming more effective the more it is used.
