+# Application Hooks Feature - Implementation Summary
+
+## Overview
+
+This PR successfully implements a comprehensive **Application Hooking System** for MSAgent-AI that allows the agent to monitor and react to applications, games, and system events with dynamic AI-powered responses.
+
+## What Was Implemented
+
+### 1. Core Hooking Infrastructure
+
+**Files Created:**
+- `src/AppHook/IAppHook.cs` - Interface defining the hook contract
+- `src/AppHook/AppHookBase.cs` - Base class with common hook functionality
+- `src/AppHook/AppHookManager.cs` - Manager for hook lifecycle and events
+- `src/AppHook/Hooks/ProcessMonitorHook.cs` - Built-in process monitoring
+- `src/AppHook/Hooks/WindowMonitorHook.cs` - Built-in window monitoring
+
+**Key Features:**
+- ✅ Extensible plugin architecture via `IAppHook` interface
+- ✅ Base class handles common functionality (logging, state, disposal)
+- ✅ Manager handles registration, lifecycle, and event forwarding
+- ✅ Thread-safe event handling with UI marshalling
+- ✅ Graceful error handling and logging
+
+### 2. Event System
+
+**AppHookEventArgs Properties:**
+- `EventType` - Type of event (Achievement, Error, Custom, etc.)
+- `Prompt` - AI prompt for dynamic responses
+- `DirectSpeech` - Direct speech text (bypasses AI)
+- `Animation` - Optional animation to play
+- `Context` - Additional context data
+- `Priority` - Event importance level
+- `Interrupt` - Whether to interrupt current activity
+
+**Event Types:**
+- ApplicationStarted
+- ApplicationStopped
+- WindowTitleChanged
+- WindowFocused/Unfocused
+- Custom
+- Achievement
+- Error
+- StatusUpdate
+- Periodic
+
+### 3. Built-in Hooks
+
+#### ProcessMonitorHook
+Monitors when a specific application starts or stops.
+
+**Features:**
+- Configurable poll interval
+- Custom AI prompts for start/stop events
+- Process name matching
+- Automatic state tracking
+
+**Example Use:**
+```csharp
+new ProcessMonitorHook(
+    "notepad",
+    "Notepad Monitor",
+    startPrompt: "User opened Notepad. Encourage their writing!",
+    stopPrompt: "User closed Notepad. Ask if they saved.",
+    pollIntervalMs: 2000
+)
+```
+
+#### WindowMonitorHook
+Monitors window title changes for applications.
+
+**Features:**
+- Detects active window
+- Tracks title changes
+- Win32 API integration
+- Configurable poll rate
+
+**Example Use:**
+```csharp
+new WindowMonitorHook(
+    "chrome",
+    "Browser Monitor",
+    pollIntervalMs: 1000
+)
+```
+
+### 4. Configuration System
+
+**AppSettings Integration:**
+```json
+{
+  "EnableAppHooks": true,
+  "AppHooks": [
+    {
+      "HookType": "ProcessMonitor",
+      "DisplayName": "Notepad Monitor",
+      "TargetApp": "notepad",
+      "Enabled": true,
+      "Parameters": {
+        "StartPrompt": "User opened Notepad!",
+        "StopPrompt": "User closed Notepad!",
+        "PollInterval": "2000"
+      }
+    }
+  ]
+}
+```
+
+**Features:**
+- JSON-based configuration
+- Enable/disable per hook
+- Extensible parameters dictionary
+- Type-specific parameter handling
+
+### 5. Integration with MainForm
+
+**Changes to MainForm.cs:**
+- Added `_hookManager` field
+- `InitializeAppHooks()` method for setup
+- `CreateHookFromConfig()` to instantiate hooks
+- `OnHookTriggered()` event handler
+- Helper methods for parameter extraction
+- Proper cleanup in `Dispose()`
+
+**Integration Points:**
+- ✅ Events forwarded to AI system (Ollama)
+- ✅ Direct speech support
+- ✅ Animation playback
+- ✅ Thread-safe UI updates
+- ✅ Lifecycle management
