Installation

Prerequisites

Rust (stable, latest) — install via rustup.rs
C compiler — cc on PATH
- macOS: Xcode Command Line Tools (xcode-select --install)
- Ubuntu/Debian: sudo apt install build-essential
- Fedora: sudo dnf install gcc

Install via Cargo

The recommended way to install DUUMBI:

cargo install duumbi

Verify the installation:

duumbi --version

Build from source

For the latest development version:

git clone https://github.com/hgahub/duumbi.git
cd duumbi
cargo build --release

The binary will be at target/release/duumbi. Add it to your PATH or use it directly.

LLM provider setup

To use AI features (duumbi add, duumbi intent), configure an LLM provider in your project’s config.toml:

[llm]
provider = "anthropic"           # or "openai", "grok", "openrouter"
api_key_env = "ANTHROPIC_API_KEY"  # environment variable containing your API key
model = "claude-sonnet-4-20250514"

Set the API key in your environment:

export ANTHROPIC_API_KEY="sk-ant-..."

Next steps

Now that DUUMBI is installed, create your first project.
