AI-powered VS Code debugger for explaining errors, previewing fixes, and applying repairs with local or cloud LLM providers.

Supported Providers

ollama
lmstudio
openai
deepseek
claude
gemini
openrouter

azure-openai

Features

aiDebugger.explainError: Analyze the current file and explain diagnostics.
aiDebugger.explainCode: Right-click Explain This Code to explain a function, class, call flow, or generate Chinese comments.
aiDebugger.previewFix: Generate a full-file fix and open a diff preview.
aiDebugger.applyFix: Apply the AI-generated repair directly to the file.
aiDebugger.setConfige: Open the extension settings page.

Default Behavior

Default provider: ollama
Default local model: qwen2.5-coder:7b
Existing Ollama users do not need to change anything.

Common Settings

aiDebugger.baseUrl
aiDebugger.model
aiDebugger.apiKey
aiDebugger.temperature
aiDebugger.maxTokens

The settings page now keeps only these five items. The provider is inferred from aiDebugger.baseUrl by default, and advanced overrides can still be supplied through environment variables or manual settings.json entries when needed.
