Supported environments

What release 0.1.1 supports, what you need installed, and what OpenHarnX makes no claim about.

OpenHarnX 0.1.1

The release boundary is the repository's release criteria. Outside it, OpenHarnX makes no claim of protection.

Supported in 0.1.1#

	Supported
Projects	Python, tested with pytest
Local verification	macOS on Apple silicon (arm64)
CI gate	Linux runners. GitHub-hosted `ubuntu-24.04` is tested; GitLab CI and Jenkins examples are provided
Sandbox	`srt` from `@anthropic-ai/sandbox-runtime` 0.0.77
Coding agents	Any, through `ohx verify` or the CI gate. Claude Code has a built-in Stop hook

Python 3.12 or newer. ohx doctor checks it.
uv, to install the ohx command.
git. The project must be a git repository with at least one commit.
Node 20 or later, for srt, the sandbox the checks run in.
A pytest suite in tests/ at the repository root. That folder is what ohx init --lock-tests and the CI gate lock.
An interpreter with your test dependencies. Checks run with python from ohx.toml, else the project's .venv or venv, else the active virtual environment.

For the CI gate the runner also needs bubblewrap, socat and ripgrep; the GitHub Action installs them. See GitHub Actions.

These work and are tested, but are outside the 0.1.1 boundary:

TypeScript and JavaScript projects (Vitest, Jest, node --test), with environment = "npm" protecting node_modules in CI.
Go projects (go test).
The advisory mutation check.
ohx bug, which drives a coding agent through one bug fix.
ohx trace, requirement coverage.

Linux outside CI, Windows, pnpm and Yarn lockfiles, Playwright, and more than one agent at a time.
