## Definition

**Assembly:** CloudNimble.ClaudeEssentials.dll

**Namespace:** CloudNimble.ClaudeEssentials.Hooks

**Inheritance:** System.Object

## Syntax

```csharp theme={"dark"}
CloudNimble.ClaudeEssentials.Hooks.ClaudeHooksSerializer
```

## Summary

Provides static helper methods for serializing and deserializing Claude Code hook types.
All methods use the AOT-compatible [ClaudeHooksJsonContext](/claudeessentials/api-reference/CloudNimble/ClaudeEssentials/Hooks/ClaudeHooksJsonContext) for serialization.

## Usage

`ClaudeHooksSerializer` provides AOT-compatible static methods for JSON serialization using source-generated contexts.

### Deserializing Input

```csharp theme={"dark"}
// Read and deserialize from stdin
string json = Console.In.ReadToEnd();

var preToolUse = ClaudeHooksSerializer.DeserializePreToolUseInput(json);
var postToolUse = ClaudeHooksSerializer.DeserializePostToolUseInput(json);
var stop = ClaudeHooksSerializer.DeserializeStopInput(json);
var notification = ClaudeHooksSerializer.DeserializeNotificationInput(json);
```

### Serializing Output

```csharp theme={"dark"}
// Create and serialize output
var output = new PreToolUseHookOutput<object> { Continue = true };
string json = ClaudeHooksSerializer.SerializePreToolUseOutput(output);
Console.WriteLine(json);
```

### Using Custom Types

For strongly-typed tool inputs, create your own `JsonSerializerContext`:

```csharp theme={"dark"}
[JsonSerializable(typeof(PreToolUseHookInput<MyToolInput>))]
public partial class MyJsonContext : JsonSerializerContext { }

var input = ClaudeHooksSerializer.DeserializePreToolUseInput<MyToolInput>(
    json, MyJsonContext.Default.PreToolUseHookInputMyToolInput);
```

## Properties

### <Icon icon="tag" iconType="duotone" color="#419AC5" size={24} className="mr-2" /> DefaultOptions

Gets the default [JsonSerializerOptions](https://learn.microsoft.com/dotnet/api/system.text.json.jsonserializeroptions) configured for Claude Code hooks.
