A terminal-based AI coding assistant written in Rust, inspired by Claude Code.
oxide-code is a Rust reimplementation of Claude Code — an interactive CLI agent that helps developers with software engineering tasks. It communicates with LLM APIs to understand codebases, write code, run commands, and manage development workflows directly from the terminal.
Early development. What works today:
- Agent loop with streaming and extended thinking
- File and search tools (read, write, edit, glob, grep, bash)
- System prompt with CLAUDE.md / AGENTS.md injection
- Authentication (API key and Claude Code OAuth)
- TOML config file with layered loading
Next up: terminal UI. See docs/roadmap.md for details.
