opencode-anthropic-auth

Why we included this project

OpenCode users who pay for Claude through a Pro or Max subscription rather than metered API credits can point their coding agent at that existing plan instead of juggling a separate key. The plugin adds an OAuth login through claude.ai, and it also includes an OAuth-assisted API key creation flow plus plain manual key entry, so it works as a single auth layer no matter how you normally authenticate. Setup is a one-liner in the plugin config followed by the /connect command. Worth knowing before you install: the README is upfront that this kind of integration may violate Anthropic's terms of service, and similar plugins have been linked to account bans under heavy usage, so pin the version and treat it as a convenience with real risk.
