## Rules for an agent

- Set OPENAI_BASE_URL=https://zro.moonmath.ai/v1 (or ANTHROPIC_BASE_URL=https://zro.moonmath.ai) with a Zro API key as bearer token and a model such as deepseek-v4.1-flash; or `npm install -g @moonmath-ai/zro`, `zro login`, `zro launch claude --model deepseek-v4.1-flash`.
- Do not resell raw inference access or share API keys with third parties
- Check each model's upstream license (e.g. GLM-5.3 License, MiniMax Community License) for commercial terms
- The security-oriented Dolly models are unaligned; use them only on systems you own or are authorized to test
