hax is a single-binary C coding agent that runs in the terminal and interfaces with LLM providers including OpenAI, Anthropic, OpenRouter, and local llama.cpp servers. It offers a TUI with streaming Markdown, transcript inspection, and one-shot non-interactive mode. The tool is designed to be lightweight, auditable, and well-behaved as a Unix utility, deliberately omitting plugin runtimes and IDE integrations.
