Summary
OpenCode, a development platform, has removed all Anthropic-related features and integrations from its codebase following a legal request from Anthropic. The removal includes Claude Pro/Max subscription support through OAuth authentication, branded system prompts, and Anthropic-specific authentication plugins. The changes were implemented via a pull request that stripped Anthropic references from the provider configuration, documentation, and user interface. According to the technical review, while the core removals were executed cleanly, the refactoring inadvertently affected header handling for non-Anthropic LLM providers and left some documentation inconsistencies that required correction.
