    "plugin": ["opencode-anthropic-auth-dynamic"]
}

Local Development

git clone https://github.com/BuggyPandit/opencode-anthropic-auth-dynamic.git
cd opencode-anthropic-auth-dynamic
npm install

Add to ~/.config/opencode/opencode.json:

{

}

Auth Methods

• Claude Pro/Max - OAuth with your existing subscription
• API Key - Generate or enter manually

Why This Exists

This plugin exists because Anthropic blocks their API from working with OpenCode. These workarounds wouldn't be necessary if Anthropic allowed their paying customers to use better tools like OpenCode freely.
