# Changelog

3+
## 0.2.0 (2025-01-XX)
4+
5+
### Breaking Changes
6+
7+
* **Client Configuration**: Constructor now requires `ArcadeClientOptions` instead of object initializer syntax
8+
* **HttpClient**: Removed from public API. Inject via `ArcadeClientOptions.HttpClient` for dependency injection support
9+
* **Type Names**: Renamed `HttpRequest`/`HttpResponse` → `ArcadeRequest`/`ArcadeResponse` to avoid ASP.NET naming conflicts
10+
11+
### Features
12+
13+
* **ArcadeClientOptions**: New strongly-typed configuration class with environment variable support
14+
* **ArcadeClientFactory**: Convenient factory methods with shared HttpClient instance
15+
* **Parameterless Constructor**: Creates client using `ARCADE_API_KEY` and `ARCADE_BASE_URL` environment variables
16+
* **XML Documentation**: Comprehensive documentation added to all public APIs
17+
18+
### Improvements
19+
20+
* Applied modern C# 12 patterns (primary constructors, expression-bodied members, string interpolation)
21+
* Added 69 behavior-focused unit tests covering edge cases and architectural validation
22+
* Proper dependency injection support for `HttpClient`
23+
* All exception types now sealed with XML documentation
24+
* Improved separation of concerns and architectural patterns
25+

49+
Console.WriteLine($"Execution ID: {result.ExecutionID}");
50+
Console.WriteLine($"Status: {result.Status}");
51+
```
52+
53+
**Tool requiring OAuth (e.g., GitHub):**
54+
```csharp
55+
// Step 1: Authorize the tool
56+
var authResponse = await client.Tools.Authorize(new ToolAuthorizeParams
57+
{
58+
ToolName = "GitHub.ListRepositories"
59+
});
60+
61+
// Step 2: After OAuth completes, execute with UserID
62+
var executeParams = new ToolExecuteParams
63+
{
64+
ToolName = "GitHub.ListRepositories",
65+
UserID = authResponse.UserID // From authorization response
66+
};
67+
68+
var result = await client.Tools.Execute(executeParams);

### List Available Tools

# Examples
2+
3+
This directory contains runnable examples demonstrating how to use the Arcade C# SDK.
4+
5+
## BasicExample
6+
7+
Demonstrates basic SDK usage including:
8+
- Creating clients with different configuration methods
9+
- Using environment variables
10+
- Using `ArcadeClientOptions`
11+
- Using `ArcadeClientFactory`
12+
- Listing tools
13+
- Health checks
14+
15+
### Running
16+
17+
```bash
18+
cd BasicExample
19+
export ARCADE_API_KEY="your-api-key"
20+
dotnet run
21+
```
22+
23+
## Requirements
24+
25+
- .NET 8 SDK
26+
- Valid Arcade API key (set via `ARCADE_API_KEY` environment variable)
27+
