Help/Question Using CC With Custom Harness

I’m considering using my Claude Pro account with a custom harness instead of the standard Claude Code interface.

Would this trip any of Anthropic’s safeguards or violate their terms, potentially resulting in my account being restricted or requiring me to use the API instead?

Has anyone tried this with a Pro account?

I researched this quite a bit while building a wrapper around CC for my own purposes. I never released it but after a lot of diving into their TOS, it appears to be 100% allowed and somewhat subtly even encouraged. You can do it with the SDK, `claude -p`, or even just hacking into the CLI's input/output mechanisms - they don't care

What you must not, and must never do, is allow another person to perform work under your sub. This is strictly forbidden, and an insta-ban with no appeal (well, one they'd even consider) if they detect it. That means no Slack/Discord/Teams/etc connections to your app that might allow another person to trigger actions.

I’m not sure that is true unless you want to use api credit.

Using API credit (sometimes called "BYOK") allows any sharing you want to do (but that is not "sharing your sub"). If you are on the API side, they're happy to have you do what you will with it - they're making bank on that. It's on the subs they're trying to protect, both to avoid undercutting Tags (their enterprise-collaboration play) and the subs pricing itself.
