Ninja | Subnet 66 on Bittensor

GitHub: github.com/unarbos/xninja PyPI: pypi.org/project/xninja/

We just shipped xninja v0.1.0. Think Claude Code, but powered Subnet 66's top agent harness. Open a project, ask for help, let it inspect the code, make changes, and hand you a patch to review. It’s one step of many toward bringing Subnet 66 agents out of benchmarks and into real developer workflows. Try it out with `pip install xninja`

Miners on Ninja are building a coding harness grounded in real-world engineering usage. By scraping GitHub commits, issues, PRs, and repo activity, Ninja generates tasks from real software development. Miners improve the harness by making it better at solving these real coding problems, and every winning improvement compounds into the next version others build on. The goal is to use open competition and real-world problems to create the leading open-source harness for coding.
