Arxd is an open-source, on-device Android agent built for RxD (Rust x Decompiler, not yet open source).
Built on Pi-Durable, Termux, and RxD, Arxd supports:
- MCP — connect external tools and services.
- Skills — extend the agent with reusable capabilities and workflows.
- CodeMode — orchestrate tool calls with code.
- Shell Execute — use capabilities provided by the Termux environment, including Node.js, Python, and Git.
- Custom model configuration — use API keys, account-based authentication, and compatible on-device GGUF models.
- Reverse engineering (coming soon) — RxD provides the core analysis capabilities, with support for more reverse-engineering workflows to come.
