About Claude Engineer
Claude Engineer is a framework that provides an interactive command-line interface and a web interface for software development tasks, using Anthropic's Claude 3.5 Sonnet model. During a conversation, the assistant can identify the need for a new tool, design it, and implement it, with hot-reloading of newly created tools and support for chaining tool calls automatically. It also tracks token usage against Anthropic's token counting API and keeps persistent conversation history with context window management.
The project is set up by cloning the repository and running it with uv or Python; the web interface is served locally at http://localhost:5000, while the CLI runs in the terminal. The web interface adds image upload and analysis, markdown rendering with syntax highlighting, and tool usage indicators. Installation instructions cover macOS, Linux and Windows. Pricing is not stated.
