OpenCode 2.2.3 lets users run their Claude Code login inside OpenCode through a built-in Claude Agent provider
The release notes say users install Claude Code, run claude auth login and select Claude Agent in /connect to use their Claude Code login and models; Anthropic's published terms let users sign in to the unmodified Claude Code binary with their own subscription but bar third parties from routing plan credentials on users' behalf, and Anthropic has not commented on the integration.
