// ============================================================================
// MODIFICATIONS FOR agent/src/commands.rs
// ============================================================================
//
// This file contains the code modifications needed to integrate the Claude
// task executor into the existing GuruRMM agent command dispatcher.
//
// INSTRUCTIONS:
// 1. Add the module declaration at the top of commands.rs
// 2. Add the use statements with other imports
// 3. Add the ClaudeExecutor field to your CommandHandler struct (if you have one)
// 4. Add the claude_task match arm in your command dispatcher
// ============================================================================

// ----------------------------------------------------------------------------
// STEP 1: Add module declaration near the top of commands.rs
// ----------------------------------------------------------------------------
// Add this line with other module declarations (e.g., after `mod shell;`)

mod claude;

// ----------------------------------------------------------------------------
// STEP 2: Add use statements with other imports
// ----------------------------------------------------------------------------
// Add these imports with your other use statements

use crate::claude::{ClaudeExecutor, ClaudeTaskCommand, ClaudeTaskResult};

// ----------------------------------------------------------------------------
// STEP 3: Initialize ClaudeExecutor (if using a struct-based approach)
// ----------------------------------------------------------------------------
// If you have a CommandHandler struct, add this field:

struct CommandHandler {
    // ... existing fields ...
    claude_executor: ClaudeExecutor,
}

impl CommandHandler {
    fn new() -> Self {
        CommandHandler {
            // ... initialize existing fields ...
            claude_executor: ClaudeExecutor::new(),
        }
    }
}

// OR, if you're using a simpler function-based approach:
// Create a global static (less ideal but simpler):

use once_cell::sync::Lazy;
static CLAUDE_EXECUTOR: Lazy<ClaudeExecutor> = Lazy::new(|| ClaudeExecutor::new());

// ----------------------------------------------------------------------------
// STEP 4: Add claude_task to your command dispatcher
// ----------------------------------------------------------------------------
// In your command handling function, add this match arm:

pub async fn handle_command(command_json: &str) -> Result<String, String> {
    // Parse command JSON
    let command: serde_json::Value = serde_json::from_str(command_json)
        .map_err(|e| format!("[ERROR] Failed to parse command JSON: {}", e))?;

    let command_type = command["command_type"]
        .as_str()
        .ok_or_else(|| "[ERROR] Missing command_type field".to_string())?;

    match command_type {
        "shell" => {
            // ... existing shell command handling ...
            execute_shell_command(&command).await
        }
        "powershell" => {
            // ... existing PowerShell command handling ...
            execute_powershell_command(&command).await
        }
        "claude_task" => {
            // NEW: Claude Code task execution
            execute_claude_task(&command).await
        }
        _ => Err(format!("[ERROR] Unknown command type: {}", command_type)),
    }
}

// ----------------------------------------------------------------------------
// STEP 5: Implement the execute_claude_task function
// ----------------------------------------------------------------------------
// Add this function to commands.rs:

async fn execute_claude_task(command: &serde_json::Value) -> Result<String, String> {
    // Parse Claude task command from JSON
    let task_cmd: ClaudeTaskCommand = serde_json::from_value(command.clone())
        .map_err(|e| format!("[ERROR] Failed to parse Claude task command: {}", e))?;

    // Get executor (use appropriate method based on your approach)
    // Option A: If using struct-based approach
    // let result = self.claude_executor.execute_task(task_cmd).await?;

    // Option B: If using global static
    let result = CLAUDE_EXECUTOR.execute_task(task_cmd).await?;

    // Serialize result to JSON
    serde_json::to_string(&result)
        .map_err(|e| format!("[ERROR] Failed to serialize Claude task result: {}", e))
}

// ============================================================================
// COMPLETE EXAMPLE: Full command dispatcher with Claude integration
// ============================================================================

// Example of a complete command handling implementation:

use serde_json;
use once_cell::sync::Lazy;

mod claude;
use crate::claude::{ClaudeExecutor, ClaudeTaskCommand};

static CLAUDE_EXECUTOR: Lazy<ClaudeExecutor> = Lazy::new(|| ClaudeExecutor::new());

pub async fn handle_command(command_json: &str) -> Result<String, String> {
    // Parse command JSON
    let command: serde_json::Value = serde_json::from_str(command_json)
        .map_err(|e| format!("[ERROR] Failed to parse command JSON: {}", e))?;

    let command_type = command["command_type"]
        .as_str()
        .ok_or_else(|| "[ERROR] Missing command_type field".to_string())?;

    match command_type {
        "shell" => execute_shell_command(&command).await,
        "powershell" => execute_powershell_command(&command).await,
        "claude_task" => execute_claude_task(&command).await,
        _ => Err(format!("[ERROR] Unknown command type: {}", command_type)),
    }
}

async fn execute_claude_task(command: &serde_json::Value) -> Result<String, String> {
    let task_cmd: ClaudeTaskCommand = serde_json::from_value(command.clone())
        .map_err(|e| format!("[ERROR] Failed to parse Claude task command: {}", e))?;

    let result = CLAUDE_EXECUTOR.execute_task(task_cmd).await?;

    serde_json::to_string(&result)
        .map_err(|e| format!("[ERROR] Failed to serialize Claude task result: {}", e))
}

// Placeholder for existing functions (already implemented in your code)
async fn execute_shell_command(_command: &serde_json::Value) -> Result<String, String> {
    // Your existing shell command implementation
    unimplemented!("Use your existing shell command implementation")
}

async fn execute_powershell_command(_command: &serde_json::Value) -> Result<String, String> {
    // Your existing PowerShell command implementation
    unimplemented!("Use your existing PowerShell command implementation")
}

// ============================================================================
// NOTES:
// ============================================================================
//
// 1. The exact integration depends on your existing code structure
// 2. If you already have a CommandHandler struct, use approach A
// 3. If you're using a simpler function-based approach, use approach B (global static)
// 4. Make sure to add error logging where appropriate
// 5. Consider adding metrics/monitoring for Claude task executions
