opencode-claude-auth Self-contained Anthropic auth provider for OpenCode using your Claude Code credentials — no separate login or API key needed. How it works The plugin registers its own auth provider with a custom fetch handler that intercepts all Anthropic API requests. It reads OAuth tokens from the macOS Keychain (or on other platforms), caches them in memory with a 30-second TTL, and handles the full request lifecycle — no builtin Anthropic auth plugin required. It also syncs credentials to OpenCode's as a fallback (on Windows, it writes to both and to cover all installation methods).
