There are so many cool harnesses I could use if I didn't have an outrageously subsidized Claude subscription

I just built my own tools and then just drive claude with 'claude -p' through them. Works great for controlling claude from my own android app.

Yes, write your own custom harness harness.

This is what I'm doing too, and it's so much better. No more blocking copy/paste, no more stuck title bars, it actually sends notifications only when I need to give it input, it feels snappy, it doesn't destroy the scrollback buffer, messages are timestamped, I can copy my prompt out without spaces being added, it automatically bumps the agent to check when background processes run too long, and I added a sandbox that actually provides a modicum of security.

Try them anyway. Tell your employer about all the principles of freedoms that free, self hosted AI enable. It does not have to dwarf other costs.

Do not worry about vendor lock-in. Standing against big corporations was never easier in this century.

Do it. You know you can.

I’m self employed, which means there is less than zero chance I could rely on self-hosted AI. $200/mo for virtually unlimited use, or $10k for a machine that will be less capable and slower?

But you can still use Claude code with a gui layer on top (if it's still calling claude code under the hood, not using the APIs directly).

At least that's what I'm using in https://beolis.com (so, you can use the actual harness you like and just have a proper UI to manage agents over it).

That’s just a harness with a hat on it

so what's the point? you can use claude sub.

Claude doesn't allow third party harnesses unless you pay the full API price. Attempting to avoid that by pretending to be Claude code gets your account banned. Google is the same and will ban your entire Google account.

AFAIK - Of the big three only OpenAI explicitly allows third party harnesses without paying exorbitant API rates. It's one of the primary reasons I still use them.

To avoid these problems some folks use tools like herdr which operate like tmux or via the SDK to drive the official harness, rather than speaking directly to the API routes.

Between this and Sol 6.1’s efficiency I don’t see any reason to use an Anthropic sub at the moment. Opus 5.5 is good but not that good.

They apparently rolled this decision back.

What they rolled back was charging claude -p "..." and use of Claude Code as an ACP agent at API rates. But the use of OAuth2 authentication with their subscription plans still feels at least risky: https://code.claude.com/docs/en/legal-and-compliance#authent... (granted, the wording is anything but clear).

Whether and under what circumstances they actually enforce this these days, I do not know. Regardless, if your preferred harness does not support that authentication flow (which most don't), then it doesn't really help you even if you could. For what it's worth, I do not consider the Claude Code ACP adapter an adequate solution.

Ja, that's the only reason I use ChatGPT instead even though I prefer Claude's current model and their native web app over that of OpenAI.

This was true but no longer is

It is, their TOS mandates CC but they do now give you an API credit

Yea, that's what I do so I don't see the issue.
