Command Code GOAT Provider

Command Code GOAT Chat Provider for GitHub Copilot in Visual Studio Code. Access 60+ AI models directly from the Copilot Chat model picker with streaming responses, tool calling, image understanding, and thinking/reasoning inspection.

Features

• 60+ AI Models: Full support for Claude 5 / 4.6 / 4.8 / 4.7 / Haiku 4.5, DeepSeek V4 Pro / Flash, Kimi K3 / K2.7 / K2.6, GLM-5.3 / 5.2, MiniMax M3, Qwen 3.8 / 3.7, Gemini 3.7 / 3.6 / 3.5, Grok 4.6 / 4.5, Muse Spark, and more.
• Dual Protocol Routing: Automatically routes Claude models to the Anthropic Messages API (/provider/v1/messages) and other models to OpenAI-compatible Chat Completions (/provider/v1/chat/completions).
• Zero Data Retention (ZDR): Optional configuration (commandcode-goat.enableZdr) to send x-cmd-zdr: 1 header for strict compliance and privacy requirements.
• Native Tool Calling & Thinking: Assembles fragmented streaming tool calls in real time and renders model reasoning blocks in Copilot Chat.
• Secure Key Storage: API keys are securely stored in VS Code's SecretStorage (commandcode-goat.apiKey) and never written to workspace files or logs.
• Resilient Streaming: Automatic silent retries for empty or truncated responses and normalized error handling for rate limits, token ceilings, and authorization issues.

Requirements

• VS Code: 1.104.0 or higher
• GitHub Copilot: Installed and active in VS Code
• Command Code API Key: From Command Code

Setup & Configuration

1. Configure Your API Key

You can configure your API key in any of the following ways:

1. Open the Command Palette (Ctrl+Shift+P / Cmd+Shift+P), run Command Code GOAT: Manage API Key, and paste your API key.
2. Select any Command Code GOAT model in the Copilot Chat model picker; VS Code will prompt you for the API key if none is stored.

2. Optional Settings

In VS Code Settings (Ctrl+, / Cmd+,), search for Command Code GOAT:

• commandcode-goat.enableZdr (boolean, default: false): Enable Command Code Zero Data Retention mode (x-cmd-zdr: 1).

3. Commands

• Command Code GOAT: Manage API Key (commandcode-goat.manage): Set, update, or clear your stored API key.
• Command Code GOAT: Toggle Debug Logging (commandcode-goat.toggleDebugLogging): Enable or disable verbose debug logs in the output channel.

Model Catalog & Protocols

The provider dynamically discovers available models from GET https://api.commandcode.ai/provider/v1/models while maintaining static capability authority:

Troubleshooting & Error Handling

• 401 / 403 Unauthorized: Your API key is missing or invalid. Use Command Code GOAT: Manage API Key to update it.
• 422 Unprocessable Entity (ZDR mode): The selected model or account tier does not support Zero Data Retention. Toggle commandcode-goat.enableZdr to false in settings.
• 429 Rate Limit: The provider rate limit has been exceeded. The extension retries with exponential backoff before surfacing errors.
• 400 Token Limit Exceeded: The conversation length exceeds the model's effective context limit. Reduce conversation history or switch to a 1M-token model.
• 5xx Server Errors: Temporary provider outage. The extension automatically retries transient server errors up to 5 times.
