## Installation

```bash
dotnet add package MarketAlly.AIPlugin.ClaudeCode
```

## Quick Start

### 1. Configure Services in Program.cs

```csharp
using MarketAlly.AIPlugin.ClaudeCode;

var builder = WebApplication.CreateBuilder(args);

// Option 1: Use configuration from appsettings.json
builder.Services.AddClaudeCodeIntegration(builder.Configuration);

// Option 2: Configure with action
builder.Services.AddClaudeCodeIntegration(options =>
{
    options.BaseUrl = "https://your-aizia-instance.com";
    options.ApiKey = "your-api-key";
    options.TenantId = "your-tenant-id";
    options.EnableRateLimiting = true;
    options.EnableLearning = true;
    options.MaxRetries = 3;
});

var app = builder.Build();

// Map Claude Code endpoints (optional - for API exposure)
app.MapClaudeCodeEndpoints();

app.Run();
```

### 2. Use in Controllers

```csharp
[ApiController]
[Route("api/[controller]")]
public class AIAssistantController : ControllerBase
{
    private readonly IClaudeCodeService _claudeCodeService;
    private readonly IChatService _chatService;
    
    public AIAssistantController(
        IClaudeCodeService claudeCodeService,
        IChatService chatService)
    {
        _claudeCodeService = claudeCodeService;
        _chatService = chatService;
    }
    
    [HttpPost("chat")]
    public async Task<IActionResult> Chat([FromBody] ChatRequest request)
    {
        var response = await _claudeCodeService.SendChatMessageAsync(request);
        
        if (response.Success)
        {
            return Ok(new { 
                response = response.Data, 
                rateLimit = response.RateLimitInfo 
            });
        }
        
        return BadRequest(new { 
            error = response.Error, 
            errorCode = response.ErrorCode 
        });
    }
    
    [HttpPost("analyze")]
    public async Task<IActionResult> AnalyzeCode([FromBody] AnalysisRequest request)
    {
        var response = await _claudeCodeService.AnalyzeCodeAsync(request);
        return response.Success ? Ok(response.Data) : BadRequest(response.Error);
    }
    
    [HttpGet("rate-limit")]
    public async Task<IActionResult> GetRateLimit()
    {
        var response = await _claudeCodeService.GetRateLimitStatusAsync();
        return Ok(response.Data);
    }
}
```

### 3. Use in Services

```csharp
public class CodeAnalysisService
{
    private readonly IClaudeCodeService _claudeCode;
    
    public CodeAnalysisService(IClaudeCodeService claudeCode)
    {
        _claudeCode = claudeCode;
    }
    
    public async Task<string> GetCodeReview(string filePath, string code)
    {
        var request = new AnalysisRequest
        {
            FilePath = filePath,
            Code = code,
            AnalysisType = "security",
            Options = new Dictionary<string, object>
            {
                ["includeRecommendations"] = true,
                ["severityLevel"] = "medium"
            }
        };
        
        var response = await _claudeCode.AnalyzeCodeAsync(request);
        return response.Success ? response.Data?.Summary ?? "No analysis available" : response.Error ?? "Analysis failed";
    }
}
```

## Rate Limiting Features

The package includes comprehensive rate limiting with:

### Multi-Tier Support
- **Free**: 100 requests/hour
- **Basic/Starter**: 500 requests/hour  
- **Professional**: 2,000 requests/hour
- **Enterprise**: 10,000 requests/hour
- **Aizia Staff/Admin**: 5,000-50,000 requests/hour

### Automatic Handling
- **Exponential Backoff**: Smart retry delays
- **Progress Indicators**: Real-time wait progress
- **Rate Limit Awareness**: Proactive limit checking
- **Graceful Degradation**: Fallback when limits exceeded

### Usage Example

```csharp
// Rate limit status monitoring
var rateLimitInfo = await _claudeCodeService.GetRateLimitStatusAsync();
if (rateLimitInfo.Success && rateLimitInfo.Data.IsNearLimit)
{
    // Handle near-limit scenario
    await Task.Delay(TimeSpan.FromMinutes(1));
}

// The HTTP client automatically handles retries
var response = await _claudeCodeService.SendChatMessageAsync(new ChatRequest
{
    Message = "Analyze this code for security issues",
    ProjectPath = "./src/MyProject",
    IncludeProjectContext = true
});
```

            break;
    }
}
```
