> for third-party harnesses

What's the exact definition of third-party harnesses? They have an Agent SDK in Claude Code that can be used. Are they trying to say that only Anthropic products can use pro/max plans?

Great question. I've read that the agent sdk is ok as long as it's not for external use - meaning you aren't selling access to it. Unclear now though!
