AnswerCode

AI-powered code Q&A system. Ask questions about your codebase and get intelligent answers using large language models (LLMs) with an agentic tool-calling loop.

Features

• Agentic Q&A: An AI agent uses tools (grep, read file, list directory, glob search) to explore your codebase and answer questions autonomously
• Multiple LLM Providers: Supports OpenAI and Azure OpenAI—add more via configuration
• Streaming Progress: Real-time SSE streaming shows tool calls as they happen
• Dark Theme UI: Web interface with syntax highlighting, Markdown rendering, and Mermaid diagram support

Prerequisites

• .NET 10.0 SDK
• LLM API access (OpenAI or Azure OpenAI)

Quick Start

1. Clone the repository and navigate to the project folder:

   cd AnswerCode

2. Configure LLM providers in appsettings.json (see Configuration below).

3. Run the application:

   dotnet run

4. Open a browser to http://localhost:5000 (or https://localhost:5001).

5. Enter your project path (e.g. project-code or an absolute path), choose a model provider, and ask a question about your code.

Configuration

LLM providers are configured under the LLM section in appsettings.json:

{
  "LLM": {
    "DefaultProvider": "OpenAI",
    "Providers": {
      "OpenAI": {
        "Endpoint": "https://your-endpoint.openai.com",
        "ApiKey": "your-api-key",
        "Model": "gpt-4o",
        "DisplayName": "GPT-4o"
      },
      "AzureOpenAI": {
        "Endpoint": "https://your-resource.cognitiveservices.azure.com/",
        "ApiKey": "your-api-key",
        "DeploymentName": "gpt-4o",
        "DisplayName": "Azure GPT-4o"
      }
    }
  }
}

Provider Types

• OpenAI (and other OpenAI-compatible endpoints): Use Endpoint, ApiKey, Model, and optionally DisplayName.
• AzureOpenAI: Use Endpoint, ApiKey, DeploymentName, and optionally DisplayName.

Local Overrides

Use appsettings.Local.json for local secrets and overrides. This file is gitignored and will override values from appsettings.json when present. Copy the structure from appsettings.json and fill in your API keys.

Agent Tools

The agent uses these tools to explore your codebase:

Tool	Description
list_directory	List files and subdirectories in a path
grep_search	Search file contents by pattern (regex)
glob_search	Find files by name pattern (e.g. *.cs)
read_file	Read file contents (with optional line range)
