Anthropic changed their API authentication to restrict Claude Pro subscriptions from working with third-party tools like Open Code, forcing users into their official Claude Code interface. This appears to be a strategic move to lock developers into Anthropic's ecosystem before competitors release better models, similar to Apple's walled garden approach. The change breaks existing workflows and prevents developers from building custom agents using the Open Code SDK with subsidized pricing, effectively killing innovation around third-party harnesses and agent frameworks that could easily switch between AI providers.

Hey Anthropic, WTF

Anthropic just locked Opus behind their own Claude Code CLI.
Try accessing Opus via other CLI tools like OpenCode and you’ll get blocked "only allowed via Claude Code".
