> 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?
When another program is doing direct tool calling instead of delegating it to Claude.
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!
