Agentic Features for Grok CLI

Inspired by Claude Code, this implementation adds advanced agentic capabilities including persistent shell sessions, background process management, task planning, and parallel tool execution.

🚀 Key Features

1. Enhanced Shell Command Execution

Persistent shell sessions that maintain working directory state across commands.

Features:

• Session Persistence: Working directory (cd) persists across commands
• Background Execution: Run long-running commands asynchronously
• Streaming Output: Real-time command output display
• Timeout Control: Configurable command timeouts
• Command History: Track all executed commands with results

Available Tools:

• run_command - Execute shell commands with enhanced capabilities
• get_shell_cwd - Get current working directory
• list_background_processes - List all background processes
• get_background_output - Get output from a background process
• kill_background_process - Terminate a background process

Slash Commands:

/shell <cmd>  # Execute shell command
/sh <cmd>     # Alias for /shell
/cwd          # Show current working directory
/pwd          # Alias for /cwd
/bg           # List background processes
/background   # Alias for /bg

Examples:

// Basic command execution
await shellManager.execute('ls -la');

// Change directory (persists across calls)
await shellManager.execute('cd /home/user/projects');
await shellManager.execute('pwd');  // Shows /home/user/projects

// Background execution
await shellManager.execute('npm run build', { background: true });

// Streaming output
await shellManager.executeStreaming('npm test', (data) => {
    console.log(data.data);
}, { timeout: 300000 });

2. Agent Task Management

Intelligent task planning, tracking, and execution system.

Features:

• Task Planning: Break down complex operations into steps
• Status Tracking: Monitor tasks (pending, in_progress, completed, failed, blocked)
• Dependency Management: Define task dependencies
• Progress Visualization: Display progress with tables and status symbols
• Task Duration Tracking: Monitor execution time

Task States:

• 🔵 pending - Task not yet started
• 🔷 in_progress - Currently executing
• 🟢 completed - Successfully finished
• 🔴 failed - Execution failed
• 🟡 blocked - Waiting for dependencies

Slash Commands:

/tasks  # View current task list with progress

Example Usage:

const { TaskManager } = require('./lib/agent');

const taskManager = new TaskManager();

// Add tasks
taskManager.addTask('Install dependencies');
taskManager.addTask('Run tests');
taskManager.addTask('Build project');

// Execute with status updates
taskManager.startTask('task_1');
// ... do work ...
taskManager.completeTask('task_1', { result: 'Success' });

// Display progress
taskManager.display();

3. Parallel Tool Execution

Execute multiple tools concurrently for improved performance.

Features:

• Concurrent Execution: Run up to 5 tools simultaneously
• Dependency Resolution: Automatically handle task dependencies
• Error Handling: Graceful failure handling for parallel operations
• Execution Modes: Parallel, sequential, or dependency-based

Example Usage:

const { ParallelToolExecutor } = require('./lib/tools');

const parallelExecutor = new ParallelToolExecutor(toolExecutor);

// Execute multiple tools in parallel
const results = await parallelExecutor.executeParallel([
    { name: 'read_file', args: { path: 'package.json' } },
    { name: 'read_file', args: { path: 'README.md' } },
    { name: 'list_directory', args: { path: '.' } }
]);

// Execute with dependencies
const results = await parallelExecutor.executeWithDependencies([
    { name: 'create_directory', args: { path: './build' }, dependencies: [] },
    { name: 'write_file', args: { path: './build/output.txt', content: 'Hello' }, dependencies: [0] }
]);

4. Tool Chaining

Build complex multi-step operations with conditional execution.

Features:

• Step-by-Step Execution: Chain multiple tools together
• Conditional Logic: Skip steps based on conditions
• Result Callbacks: Process intermediate results
• Error Propagation: Stop chain on first error

Example Usage:

const { ToolChain } = require('./lib/tools');

const chain = new ToolChain(toolExecutor);

chain
    .add('create_directory', { path: './dist' })
    .add('write_file', {
        path: './dist/index.js',
        content: 'console.log("Hello");'
    })
    .add('run_command', {
        command: 'node ./dist/index.js'
    }, {
        onResult: (result) => {
            console.log('Output:', result.stdout);
        }
    });

await chain.execute();

📋 Architecture Overview

Components

1. ShellManager (lib/shell.js)

   • Manages persistent shell sessions
   • Handles background processes
   • Maintains working directory state
   • Provides streaming output

2. TaskManager (lib/agent.js)

   • Plans and tracks tasks
   • Manages task dependencies
   • Visualizes progress
   • Exports/imports task state

3. ParallelToolExecutor (lib/tools.js)

   • Executes tools concurrently
   • Resolves dependencies
   • Handles errors gracefully

4. ToolChain (lib/tools.js)

   • Builds complex workflows
   • Supports conditional execution
   • Provides result callbacks

Integration with Grok

The agentic features are integrated into the Grok CLI through:

1. Enhanced Tool Definitions: New tools for shell and process management
2. Slash Commands: Direct access to shell and task features
3. Function Calling: Tools available to the LLM for autonomous execution

🎯 Use Cases

1. Complex Development Workflows

> Help me set up a new React project and run tests

Grok will:
1. Create project directory
2. Initialize npm
3. Install dependencies
4. Create project structure
5. Run tests in background
6. Monitor test output

2. Multi-Step Operations

> Clone the repo, install deps, and start the dev server

Grok can:
1. Execute git clone
2. Change to project directory (cd persists)
3. Run npm install
4. Start dev server in background
5. Monitor server logs

3. System Administration

> Check disk usage, clean logs older than 30 days, and restart services

Grok can:
1. Execute df -h in parallel with du commands
2. Find and remove old logs
3. Restart services with systemctl
4. Monitor restart status

🔧 Configuration

Shell Session Options

const shellManager = new ShellManager();

// Execute with custom options
await shellManager.execute('command', {
    timeout: 60000,        // 1 minute timeout
    background: true,      // Run in background
    cwd: '/custom/path'    // Override working directory
});

Task Manager Options

const taskManager = new TaskManager();

// Add task with dependencies
taskManager.addTask('Build project', {
    dependencies: ['task_1', 'task_2'],
    metadata: { priority: 'high' }
});

Parallel Execution Options

const parallelExecutor = new ParallelToolExecutor(toolExecutor);
parallelExecutor.maxConcurrent = 3; // Limit to 3 concurrent executions

🧪 Testing

Test Shell Commands

# In Grok interactive mode:
/shell ls -la
/shell cd /tmp
/cwd  # Should show /tmp
/shell pwd  # Should show /tmp

Test Background Processes

/shell sleep 30 &
/bg  # Should show the background process

Test Task Management

/tasks  # View current tasks

🚨 Security Considerations

1. Command Approval: All commands require approval (except in auto modes)
2. Sandboxing: Commands run in the user's context (no privilege escalation)
3. Timeout Protection: All commands have configurable timeouts
4. Error Handling: Graceful failure handling prevents cascading errors
