Why we included this project
If you already pay for Claude Code and want to use OpenCode, this plugin saves you from setting up a second Anthropic login. It reads the OAuth tokens Claude Code has already stored, from the macOS Keychain or the credentials file on Linux and Windows, and hands them to OpenCode's Anthropic provider. Near-expiry tokens get refreshed directly through Anthropic's OAuth endpoint, so renewal doesn't burn LLM tokens, and credentials are synced into OpenCode's auth.json as a fallback. On macOS it even detects multiple Claude Code accounts and lets you switch between them with `opencode auth login`. For teams standardizing on OpenCode while already paying for Claude Code, that removes a real chunk of setup friction and keeps API-key management in one place.
