# Jev Harness Apixly’s independent MIT Python runtime for bounded Jev agent loops. Not an official TypeSafe AI product. Distribution: apixly-jev-harness. Python namespace: apixly_jev_harness. CLI: jev-harness / apixly-jev-harness. Version: 0.1.17. Install: pip install 'git+https://github.com/apixly-ai/jev-harness.git@v0.1.17'. The PyPI name jev-harness belongs to an unrelated project. Programs provide registered tools and parameter candidates, execute effects and independently verify completion. Jev selects supplied references. Inference is billable; unknown usage remains unknown. No general success or savings guarantee. Historical browser acceptance uses a local synthetic fixture. Homepage media is a zero-inference screenshot replay. Native desktop completion remains unverified. ## English - [Homepage](https://apixly-ai.github.io/jev-harness/): Jev Harness identity, visual cases and installation. - [Python agent task contract](https://apixly-ai.github.io/jev-harness/agent-contract.html): Install Jev Harness, define typed tools and parameter candidates, and run bounded Python tasks with explicit context and independent verification. - [Context management for Jev agent loops](https://apixly-ai.github.io/jev-harness/context.html): How Jev Harness admits goals, facts, dialogue and tool results, preserves evidence references, and blocks repeated actions against unchanged state. - [Browser and desktop task adapters](https://apixly-ai.github.io/jev-harness/adapters.html): Connect bounded Jev Harness tasks to headless Camofox, macOS Accessibility or Windows UIA.
