The thing that annoys me most of all is they block me from using OpenCode with my Claude Max plan. I find the OpenCode UI to be meaningfully better than Claude Code's, so this is really annoying.

Some workarounds are here https://github.com/anomalyco/opencode/issues/7410 but I agree with you, this should be a native feature.

if you are an expert developer smarter than everyone at anthropic, like everyone else commenting on this post, you'll know that it's not difficult to use the claude agent sdk behind an api to achieve almost exactly the same thing
