▸ 01 · install

One line. Checksum-verified prebuilt binary, then ~/.local/bin (or /usr/local/bin). If odek version is not found, add that directory to PATH.

curl -fsSL https://odek.21no.de/install.sh | sh

copied — paste in a terminal. The installer refuses to install anything it cannot verify against the release checksums.

Later, odek upgrade self-updates from GitHub Releases the same way (SHA-256 verified). The script is readable here — pipe-to-sh should always be a choice, not a habit.

▸ 02 · configure

Initialize once, then choose your provider below. odek init --global creates ~/.odek/config.json with restricted permissions and refuses to overwrite an existing configuration without --force.

odek init --global

Merge the selected example into ~/.odek/config.json, preserving your other settings. Keep API keys in ~/.odek/secrets.env.

  }
}

OPENROUTER_API_KEY=your-api-key-here

Open ~/.odek/secrets.env in your editor and add or update the selected key entry. Replace the placeholder with your actual key, preserve any other entries, then restrict file permissions:

chmod 600 ~/.odek/secrets.env

Provider settings belong in your global configuration. A project ./odek.json cannot set providers, endpoints, or keys. The examples reference key variables explicitly, including OPENROUTER_API_KEY for the custom provider. More options: PROVIDERS.md.

▸ 03 · sandbox

Tool execution runs inside an isolated Docker container by default for odek run, odek continue, odek repl, and odek serve. No Docker? Opt out before the first run:

export ODEK_NO_SANDBOX=1     # add to ~/.zshrc / ~/.bashrc
# or per-run:
odek run --no-sandbox "..."

Unsandboxed runs warn loudly. ODEK_REQUIRE_SANDBOX=1 makes them fatal instead. Full model: SANDBOXING.md.

▸ 04 · first run

You should see your configured model in the run header and a short ReAct trace: think → act → answer.

odek run "List the Go files in this directory and count their total lines"

illustration your model · think → act → answer

odek repl

Web UI — streams tokens, tools, and approvals. It binds 127.0.0.1:8080 and prints a token URL. Open that URL; a bare http://127.0.0.1:8080 loads the chrome but cannot connect.

odek serve
# → http://127.0.0.1:8080/?token=…
