AI-Generated Review

What is opencode-claude-auth?

This TypeScript plugin for OpenCode pulls your existing Claude Code credentials from macOS Keychain or the ~/.claude/.credentials.json file, letting you skip separate logins entirely. It auto-refreshes expiring tokens by triggering the Claude CLI when needed and injects the Anthropic session prompt for OpenCode versions above 1.2.27. Developers get seamless opencode claude auth without re-entering keys.

Why is it gaining traction?

It overrides OpenCode's built-in Anthropic auth for true zero-config setup, handling macOS Keychain access, cross-platform fallbacks, and proactive refreshes that keep sessions alive during long coding sessions. The simple npm install and opencode.json config beats manual API key copying, especially for opencode claude auth plugin users juggling Claude Code CLI with OpenCode's GitHub integration or agent features. Troubleshooting docs cover common pitfalls like locked Keychains upfront.

Who should use this?

Full-stack devs running Claude Code CLI alongside OpenCode for AI-assisted coding in VS Code or JetBrains. Mac users tired of token expiry interrupting opencode github copilot-like workflows, or Linux/Windows folks relying on the credentials file for opencode plugin install simplicity. Ideal for opencode plugin marketplace explorers wanting quick Anthropic model access without enterprise key hassles.

Verdict

Grab it if you're deep in the Claude ecosystem—solid user-facing features and clear install/usage docs make it a time-saver despite 34 stars and 1.0% credibility score signaling early maturity. Skip for production unless you verify token handling fits your setup; test in a side project first.
