Harness Arena CLI

ha — the command-line client for the Harness Arena competition.

Install

curl -fsSL https://get.harnessarena.xyz/install.sh | sh

The installer downloads the ha binary for your platform, verifies its SHA-256 checksum, and installs it to ~/.local/bin/ha. It does not use sudo and writes nothing outside your home directory.

Inspect before you run

Read the installer and check the artifacts before executing:

• install.sh — the install script served here
• Source on GitHub — the code that builds these binaries

The installer downloads the per-platform binary from /cli/latest/ha-<os>-<arch> and its .sha256 checksum, and verifies the checksum before installing.
