Is OpenHarnX right for you?
A good fit for
Fits Python projects whose reviewers can agree meaningful acceptance tests before a coding agent changes the implementation.
Before you choose
Release 0.1.1 documents Python/pytest support on macOS arm64 locally and Linux CI with the srt sandbox. JavaScript, TypeScript and Go are experimental. Without agreed acceptance tests a passing result supports no regressions rather than task completion. Tests, environment protection and sandbox configuration determine coverage. A verdict never authorizes merging or proves correctness. Vendor replay results are not our benchmarks. No package was installed or agent change verified.
Workflow and handoff
Agree acceptance criteria, lock tests and baseline, let the coding agent make a change, run verification in the supported sandbox and review both failures and unverified requirements before merging.
