## Usage Patterns

### Starting a New Session

```json
// 1. Initialize with topic
{
  "tool": "ConversationContinuity",
  "parameters": {
    "action": "initialize",
    "topic": "user interface redesign",
    "projectPath": "./WebApp"
  }
}

// 2. Find relevant previous discussions
{
  "tool": "ConversationContinuity",
  "parameters": {
    "action": "find_relevant",
    "searchQuery": "UI design user experience",
    "projectPath": "./WebApp"
  }
}
```

### During Development

```json
// Store important decisions
{
  "tool": "ConversationContinuity",
  "parameters": {
    "action": "store_decision",
    "information": "Implemented responsive grid system using CSS Grid instead of Flexbox for better browser support",
    "summary": "CSS Grid implementation for responsive design",
    "priority": "medium",
    "tags": "css, responsive, grid, ui"
  }
}

// Search for related information
{
  "tool": "ContextSearch",
  "parameters": {
    "query": "responsive design mobile",
    "contextType": "all",
    "daysBack": 14
  }
}
```

### Ending a Session

```json
{
  "tool": "ConversationContinuity",
  "parameters": {
    "action": "summarize_session",
    "sessionSummary": "Completed responsive design implementation. Next steps: test on mobile devices and optimize performance.",
    "topic": "responsive design"
  }
}
```

## File Structure

The plugins create and manage the following file structure:

```
ProjectRoot/
├── .context/
│   ├── context-2025-06.json      # Current month's context entries
│   ├── context-2025-05.json      # Previous month's entries
│   ├── context-index.json        # Quick search index
│   └── ...
├── conversation-context.json     # Optional: conversation history
└── refactor-config.json          # Project configuration
```

## Configuration

### Context Storage Configuration

The plugins respect the project's `refactor-config.json` for exclusions:

```json
{
  "ExcludedFiles": ["*.Designer.cs", "*.generated.cs"],
  "Context": {
    "MaxFileSize": 10000,
    "MaxContextEntries": 1000,
    "RetentionDays": 90
  }
}
```

### Environment Variables

- `CLAUDE_CONTEXT_PATH`: Override default context storage location
- `CLAUDE_MAX_CONTEXT_SIZE`: Override default maximum context size

## Best Practices

### For Claude (AI Assistant)

1. **Always initialize** when starting work on a project:
   ```json
   {"tool": "ConversationContinuity", "parameters": {"action": "initialize", "topic": "current focus"}}
   ```

2. **Store important decisions** immediately:
   ```json
   {"tool": "ConversationContinuity", "parameters": {"action": "store_decision", "information": "...", "summary": "..."}}
   ```

3. **Search before making recommendations** to avoid repeating previous discussions:
   ```json
   {"tool": "ContextSearch", "parameters": {"query": "relevant keywords"}}
   ```

4. **Summarize sessions** before ending:
   ```json
   {"tool": "ConversationContinuity", "parameters": {"action": "summarize_session", "sessionSummary": "..."}}
   ```

### For Developers

1. **Register all plugins** in your plugin registry
2. **Use meaningful tags** when storing context
3. **Set appropriate priorities** for different types of information
4. **Regular cleanup** of old context files (implement retention policies)

## Integration Examples

### With Existing MarketAlly Plugins

```csharp
// Combine with code analysis
var analysisResult = await registry.CallFunctionAsync("CodeAnalysis", parameters);

// Store the analysis insights
await registry.CallFunctionAsync("ContextStorage", new Dictionary<string, object>
{
    ["contextType"] = "insight",
    ["content"] = JsonSerializer.Serialize(analysisResult.Result),
    ["summary"] = "Code analysis results for authentication module",
    ["tags"] = "analysis, code-quality, authentication",
    ["priority"] = "medium"
});
```

### With External Tools

```csharp
// Before starting major refactoring
var contextResult = await registry.CallFunctionAsync("ConversationContinuity", new Dictionary<string, object>
{
    ["action"] = "find_relevant",
    ["searchQuery"] = "refactoring authentication security"
});

// Use context to inform refactoring decisions
var refactorResult = await registry.CallFunctionAsync("BatchRefactor", refactorParameters);

// Store refactoring outcomes
await registry.CallFunctionAsync("ContextStorage", new Dictionary<string, object>
{
    ["contextType"] = "codechange",
    ["content"] = "Refactored authentication system with improved security",
    ["summary"] = "Authentication refactoring completed",
    ["tags"] = "refactoring, authentication, security, completion"
});
```

## Troubleshooting

### Common Issues

1. **Context files not found**
   - Ensure `.context` directory exists and is writable
   - Check `projectPath` parameter is correct

2. **Search returns no results**
   - Verify context has been stored using `ContextStorage`
   - Check search terms and filters
   - Try broader search queries

3. **Context size too large**
   - Reduce `maxContextSize` parameter
   - Use more specific context types
   - Implement context cleanup

### Debugging

Enable detailed logging by checking the plugin results:

```csharp
var result = await registry.CallFunctionAsync("ContextSearch", parameters);
Console.WriteLine($"Success: {result.IsSuccess}");
Console.WriteLine($"Message: {result.Message}");
if (result.Result != null)
{
    Console.WriteLine($"Result: {JsonSerializer.Serialize(result.Result, new JsonSerializerOptions { WriteIndented = true })}");
}
```

## Security Considerations

1. **Sensitive Information**: Be careful not to store sensitive data (passwords, API keys) in context
2. **File Permissions**: Ensure `.context` directory has appropriate permissions
3. **Data Retention**: Implement cleanup policies for old context data
4. **Access Control**: Consider access controls if working in shared environments

## Performance Tips

1. **Use context types** to filter searches and reduce processing time
2. **Set reasonable `maxResults`** limits to avoid overwhelming responses
3. **Regular maintenance** of context files to prevent excessive growth
4. **Use tags effectively** for faster and more accurate searches
