OpenHarnX

OpenHarnX acts as an independent verifier for code changes, ensuring the integrity of your codebase. Key features include: • Safeguards agreed-upon tests from modifications • Executes verification in an isolated sandbox environment • Generates an evidence-backed review brief • Identifies verified changes, certain outcomes, and areas needing human judgment This platform prevents coding agents from misreporting test successes by running original, locked test copies. It's designed to provide an unbiased assessment of code quality, ensuring that new contributions don't inadvertently introduce regressions or break existing functionality. By operating independently, OpenHarnX eliminates the conflict of interest where a development agent might grade its own work. OpenHarnX is an open-source solution, released under the Apache 2.0 license, and is compatible with any coding agent through its command-line interface or CI integration. It includes a built-in Claude code integration for streamlined use. It currently supports Python with pytest on macOS arm64 locally and Linux in CI, with experimental support for TypeScript, JavaScript, and Go. Ideal for development teams, quality assurance engineers, and project managers who rely on coding agents but need an independent verification layer to maintain code standards and prevent unintended side effects.
