Can anyone ELI5 what is open code and why Anthropic is asking them to delete something ?

OpenCode is an agentic coding CLI, similar to Claude Code, Codex etc. It supports different LLM providers, including Claude.

It originally had support for copying over your Claude subscription token and calling the same backend APIs as Claude Code, which meant you could use OpenCode with your Claude Pro/Max plans, but Anthropic came out and said that the plans were only meant for first-party clients, and everyone else should be using per-token billing.

Now OpenCode is removing this option from their product, it seems because of legal threats from Anthropic.

OpenCode is a agent .. harnest? The CLI or UI tool you use as an AI agent, similar to ClaudeCode.

You where not allowed to use your ClaudeCode subscription with other tool then ClaudeCode. I'm not sure if this is what got removed or if there is more too it.

But the PR is also removing the ability to use Anthropic API key as well not just Claude Code subscription

That's just them being vindictive. Anthropic doesn't care about API use, it's paid per token anyway and they set the prices for that.

Harness :)

Harnest.

That’s only if you use it in earnest, I would think

Anthropic's ToS doesn't allow the subscribers to use third party tools that utilizes the APIs Claude Code uses. Open Code is one of those tools.
