🚀 Quick Start

Prerequisites

Before you begin, make sure you have:

• Node.js 16+ installed
• Docker Desktop or Docker Engine (will be installed automatically if missing)
• API keys for your chosen LLM provider(s)

🆕 Auto-Docker Installation: Dank will automatically detect, install, and start Docker if it's not available on your system. No manual setup required!

1. Install Dank globally

npm install -g dank-ai

2. Initialize a new project

# Create and navigate to your project directory
mkdir my-agent-project
cd my-agent-project

# Initialize Dank project
dank init my-agent-project

This creates:

my-agent-project/
├── dank.config.js         # Your agent configuration
├── agents/                # Custom agent code (optional)
│   └── example-agent.js
└── .dank/                 # Generated files
    └── project.yaml

3. Set up environment variables

Create a .env file or export environment variables:

# For OpenAI
export OPENAI_API_KEY="your-openai-api-key"

# For Anthropic
export ANTHROPIC_API_KEY="your-anthropic-api-key"

# For Cohere
export COHERE_API_KEY="your-cohere-api-key"

4. Configure your agents

Edit dank.config.js to define your agents:

const { createAgent } = require('dank');

module.exports = {
  name: 'my-agent-project',
  
  agents: [
    createAgent('assistant')
      .setLLM('openai', {
        apiKey: process.env.OPENAI_API_KEY,
        model: 'gpt-3.5-turbo',
        temperature: 0.7
      })
      .setPrompt('You are a helpful assistant that responds with enthusiasm!')
      .setInstanceType('small')
      .addHandler('output', (data) => {
        console.log('Assistant says:', data);
      })
  ]
};

5. Build Docker images (optional)

# Build agent images (base image is pulled automatically)
dank build

### 6. Start your agents
```bash
# Start all agents
dank run

# Or run in detached mode (background)
dank run --detached

7. Monitor your agents

# Check agent status
dank status

# Watch status in real-time
dank status --watch

# View agent logs
dank logs assistant

# Follow logs in real-time
dank logs assistant --follow

8. Build for production (optional)

# Build production images with custom naming
dank build:prod

# Build and push to registry
dank build:prod --push

# Build with custom tag and registry
dank build:prod --tag v1.0.0 --registry ghcr.io --namespace myorg --push

# Use a common image name and tag by agent
dank build:prod --registry ghcr.io --namespace myorg --tag-by-agent --push

📋 CLI Commands

Core Commands

dank run                    # Start all defined agents
dank status                 # Show agent status  
dank stop [agents...]       # Stop specific agents
dank stop --all            # Stop all agents
dank logs [agent]          # View agent logs

Management Commands

dank init [name]           # Initialize new project
dank build                 # Build Docker images
dank build:prod            # Build agent images with custom naming
dank clean                 # Clean up Docker resources

Agent Image Build Commands

dank build:prod                    # Build with agent image config
dank build:prod --push             # Build and push to registry (CLI only)
dank build:prod --tag v1.0.0       # Build with custom tag
dank build:prod --registry ghcr.io # Build for specific registry

🤖 Agent Configuration

Basic Agent Setup

const agent = createAgent('my-agent')
  .setLLM('openai', {
    apiKey: process.env.OPENAI_API_KEY,
    model: 'gpt-4',
    temperature: 0.8
  })
  .setPrompt('Your system prompt here')
  .setPromptingServer({
    port: 3000,
    authentication: false,
    maxConnections: 50
  })
  .setInstanceType('medium');

Adding HTTP Routes

HTTP automatically enables when you add routes. Here's a simple "Hello World" POST endpoint:

const agent = createAgent('hello-agent')
  .setLLM('openai', {
    apiKey: process.env.OPENAI_API_KEY,
    model: 'gpt-3.5-turbo'
  })
  .setPromptingServer({
    port: 3000
  })
  // Add a POST endpoint (HTTP auto-enables)
  .post('/hello', (req, res) => {
    res.json({ 
      message: 'Hello, World!',
      received: req.body,
      timestamp: new Date().toISOString()
    });
  });

Test it:

curl -X POST http://localhost:3000/hello \
  -H "Content-Type: application/json" \
  -d '{"name": "User"}'

Response:

{
  "message": "Hello, World!",
  "received": {"name": "User"},
  "timestamp": "2024-01-15T10:30:00.000Z"
}

  model: 'your-model'
})

Event Handlers

Dank provides a comprehensive event system with three main sources of events. Each event handler follows specific naming patterns for maximum flexibility and control.

🆕 Auto-Detection: Dank automatically enables communication features based on your usage:

• Event Handlers: Auto-enabled when you add .addHandler() calls
• Direct Prompting: Auto-enabled when you use .setPrompt() + .setLLM()
• HTTP API: Auto-enabled when you add routes with .get(), .post(), etc.

🎯 Event Handler Patterns

1. Direct Prompting Events (request_output)

Events triggered when agents receive and respond to direct prompts via HTTP:

agent
  // Main LLM response event
  .addHandler('request_output', (data) => {
    console.log('LLM Response:', {
      prompt: data.prompt,                    // Original prompt
      finalPrompt: data.finalPrompt,          // Modified prompt (if changed)
      response: data.response,                // LLM response
      conversationId: data.conversationId,
      processingTime: data.processingTime,
      promptModified: data.promptModified,    // Boolean: was prompt modified?
      usage: data.usage,
      model: data.model
    });
  })
  
  // Lifecycle events with modification capabilities
  .addHandler('request_output:start', (data) => {
    console.log('Processing prompt:', data.conversationId);
    console.log('Original prompt:', data.prompt);
    
    // ✨ MODIFY PROMPT: Return modified data to change the prompt sent to LLM
    const enhancedPrompt = `Context: You are a helpful assistant. Please be concise and friendly.\n\nUser Question: ${data.prompt}`;
    
    return {
      prompt: enhancedPrompt  // This will replace the original prompt
    };
  })
  
  .addHandler('request_output:end', (data) => {
    console.log('Completed in:', data.processingTime + 'ms');
    console.log('Original response:', data.response.substring(0, 50) + '...');
    
    // ✨ MODIFY RESPONSE: Return modified data to change the response sent to caller
    const enhancedResponse = `${data.response}\n\n---\n💡 This response was generated by Dank Framework`;
    
    return {
      response: enhancedResponse  // This will replace the original response
    };
  })
  
  .addHandler('request_output:error', (data) => {
    console.error('Prompt processing failed:', data.error);
  });

🔄 Event Modification Capabilities:

• request_output:start: Can modify the prompt before it's sent to the LLM by returning an object with a prompt property
• request_output:end: Can modify the response before it's sent back to the caller by returning an object with a response property
• Event Data: All events include both original and final values, plus modification flags for tracking changes

⏱️ Event Flow Timeline:

1. request_output:start → Fires when prompt is received

   • Can modify prompt before LLM processing
   • Contains: { prompt, conversationId, context, timestamp }

2. LLM Processing → The (potentially modified) prompt is sent to the LLM

3. request_output → Fires after LLM responds successfully

   • Contains: { prompt, finalPrompt, response, conversationId, promptModified, ... }

4. request_output:end → Fires after request_output, before sending to caller

   • Can modify response before returning to client
   • Contains: { prompt, finalPrompt, response, conversationId, promptModified, success, ... }

5. Response Sent → The (potentially modified) response is sent back to the caller

💡 Practical Examples:

// Example 1: Add context and formatting to prompts
.addHandler('request_output:start', (data) => {
  // Add system context and format the user's question
  const enhancedPrompt = `System: You are a helpful AI assistant. Be concise and professional.

User Question: ${data.prompt}

Please provide a clear, helpful response.`;
  
  return { prompt: enhancedPrompt };
})

// Example 2: Add metadata and branding to responses
.addHandler('request_output:end', (data) => {
  // Add footer with metadata and branding
  const brandedResponse = `${data.response}

---
🤖 Generated by Dank Framework Agent
⏱️ Processing time: ${data.processingTime}ms
🆔 Conversation: ${data.conversationId}`;
  
  return { response: brandedResponse };
})

// Example 3: Log and analyze all interactions
.addHandler('request_output', (data) => {
  // Log for analytics
  console.log('Interaction logged:', {
    originalPrompt: data.prompt,
    modifiedPrompt: data.finalPrompt,
    wasModified: data.promptModified,
    responseLength: data.response.length,
    model: data.model,
    usage: data.usage
  });
})

2. Tool Events (tool:*)

Events triggered by tool usage, following the pattern tool:<tool-name>:<action>:<specifics>:

agent
  // Example: Tool events for built-in tools
  .addHandler('tool:httpRequest:*', (data) => {
    // Listen to ALL HTTP request tool events
    console.log('HTTP Request Tool:', data);
  });

Tool Event Pattern Structure:

• tool:<tool-name>:* - All events for a specific tool
• tool:<tool-name>:call - Tool invocation/input events
• tool:<tool-name>:response - Tool output/result events
• tool:<tool-name>:error - Tool-specific errors

Note: HTTP API routes (added via .get(), .post(), etc.) are part of the main HTTP server, not a separate tool. They don't emit tool events.

3. System Events (Legacy/System)

Traditional system-level events:

agent
  .addHandler('output', (data) => {
    console.log('General output:', data);
  })
  
  .addHandler('error', (error) => {
    console.error('System error:', error);
  })
  
  .addHandler('heartbeat', () => {
    console.log('Agent heartbeat');
  })
  
  .addHandler('start', () => {
    console.log('Agent started');
  })
  
  .addHandler('stop', () => {
    console.log('Agent stopped');
  });

🔥 Advanced Event Patterns

Wildcard Matching:

// Listen to all tool events
.addHandler('tool:*', (data) => {
  console.log('Any tool activity:', data);
})


// Listen to all request outputs
.addHandler('request_output:*', (data) => {
  console.log('Any request event:', data);
})

Multiple Handlers:

// Multiple handlers for the same event
agent
  .addHandler('request_output', (data) => {
    // Log to console
    console.log('Response:', data.response);
  })
  .addHandler('request_output', (data) => {
    // Save to database
    saveToDatabase(data);
  })
  .addHandler('request_output', (data) => {
    // Send to analytics
    trackAnalytics(data);
  });

📊 Event Data Structures

Request Output Event Data:

{
  prompt: "User's input prompt",
  response: "LLM's response",
  conversationId: "unique-conversation-id",
  usage: { total_tokens: 150, prompt_tokens: 50, completion_tokens: 100 },
  model: "gpt-3.5-turbo",
  processingTime: 1250,
  timestamp: "2024-01-15T10:30:00.000Z"
}

npm

🎛️ Communication Method Control

Each communication method can be enabled/disabled independently:

createAgent('flexible-agent')
  // Configure direct prompting with specific settings
  .setPromptingServer({ 
    port: 3000,
    authentication: false,
    maxConnections: 50
  })
  .disableDirectPrompting() // Disable if needed
  
  // Listen to direct prompting events only
  .addHandler('request_output', (data) => {
    console.log('HTTP response:', data.response);
  })
  
  // Add HTTP API routes (HTTP auto-enables)
  .get('/api/status', (req, res) => {
    res.json({ status: 'ok' });
  });

Resource Management

Configure container resources:

.setInstanceType('small')  // Options: 'small', 'medium', 'large', 'xlarge'
// small: 512m, 1 CPU
// medium: 1g, 2 CPU
// large: 2g, 2 CPU
// xlarge: 4g, 4 CPU

Note: setInstanceType() is only used during deployments to Dank Cloud services. When running agents locally with dank run, this setting is disregarded and containers run without resource limits.

Agent Image Configuration

Configure Docker image naming and registry settings for agent builds:

// Complete agent image configuration
.setAgentImageConfig({
  registry: 'ghcr.io',           // Docker registry URL
  namespace: 'mycompany',        // Organization/namespace
  tag: 'v1.0.0'                 // Image tag
})

🏗️ Agent Image Build Workflow

The agent image build feature allows you to create properly tagged Docker images for deployment to container registries. This is essential for:

• CI/CD Pipelines: Automated builds and deployments
• Container Orchestration: Kubernetes, Docker Swarm, etc.
• Multi-Environment Deployments: Dev, staging, production
• Version Management: Semantic versioning with tags

📝 Note: Image pushing is controlled exclusively by the CLI --push option. Agent configuration only defines image naming (registry, namespace, tag) - not push behavior.

📋 Complete Agent Image Example

const { createAgent } = require('dank');

module.exports = {
  name: 'production-system',
  
  agents: [
    // Production-ready customer service agent
    createAgent('customer-service')
      .setLLM('openai', {
        apiKey: process.env.OPENAI_API_KEY,
        model: 'gpt-4',
        temperature: 0.7
      })
      .setPrompt('You are a professional customer service representative.')
      .setPromptingServer({
        port: 3000,
        authentication: true,
        maxConnections: 100
      })
      .setInstanceType('medium')
      // Agent image configuration
      .setAgentImageConfig({
        registry: 'ghcr.io',
        namespace: 'mycompany',
        tag: 'v1.2.0'
      })
      .addHandler('request_output', (data) => {
        // Log for production monitoring
        console.log(`[${new Date().toISOString()}] Customer Service: ${data.response.substring(0, 100)}...`);
      }),

    // Data processing agent with different registry
    createAgent('data-processor')
      .setLLM('openai', {
        apiKey: process.env.OPENAI_API_KEY,
        model: 'gpt-4',
        temperature: 0.1
      })
      .setPrompt('You are a data analysis expert.')
      .setPromptingServer({
        port: 3001,
        authentication: false,
        maxConnections: 50
      })
      .setInstanceType('large')
      // Different agent image configuration
      .setAgentImageConfig({
        registry: 'docker.io',
        namespace: 'mycompany',
        tag: 'latest'
      })
      .addHandler('request_output', (data) => {
        console.log(`[Data Processor] Analysis completed: ${data.processingTime}ms`);
      })
  ]
};

dank build:prod --force --push

# Build with custom tag and push
dank build:prod --tag release-2024.1 --push

Deployment Metadata Output:

# Generate deployment metadata JSON file
dank build:prod --output-metadata deployment.json

# Build, push, and generate metadata
dank build:prod --push --output-metadata deployment.json

# Use with custom configuration
dank build:prod --config production.config.js --output-metadata deployment.json

The --output-metadata option generates a JSON file containing all deployment information needed for your backend infrastructure:

• Base image used (setBaseImage() value)
• Prompting server configuration (port, authentication, maxConnections)
• Resource limits (memory, CPU, timeout)
• Ports that need to be opened
• Features enabled (direct prompting, HTTP API, event handlers)
• HTTP server configuration (if enabled)
• LLM provider and model information
• Event handlers registered
• Environment variables required
• Build options (registry, namespace, tag, image name)

This metadata file is perfect for CI/CD pipelines to automatically configure your deployment infrastructure, determine which ports to open, and which features to enable/disable.

🚨 Troubleshooting Production Builds

Common Issues:

1. Registry Authentication:

   # Error: authentication required
   # Solution: Login to registry first
   docker login ghcr.io

2. Push Permissions:

   # Error: denied: push access denied
   # Solution: Check namespace permissions or use personal namespace
   dank build:prod --namespace your-username --push

3. Image Already Exists:

   # Error: image already exists
   # Solution: Use different tag or force rebuild
   dank build:prod --tag v1.2.1 --push

4. Build Context Issues:

   # Error: build context too large
   # Solution: Add .dockerignore file
   echo "node_modules/" > .dockerignore
   echo "*.log" >> .dockerignore

📦 Package Exports

When you install Dank via npm, you can import the following:

const { 
  createAgent,     // Convenience function to create agents
  DankAgent,       // Main agent class
  DankProject,     // Project management class
  SUPPORTED_LLMS,  // List of supported LLM providers
  DEFAULT_CONFIG   // Default configuration values
} = require("dank");

📋 Example Files

The examples/ directory contains two configuration files:

• dank.config.js - Local development example (uses ../lib/index.js)
• dank.config.template.js - Production template (uses require("dank"))

For Local Development

# Use the example file directly
dank run --config example/dank.config.js

For Production Use

# 1. Copy the template to your project
cp example/dank.config.template.js ./dank.config.js

# 2. Install dank as a dependency
npm install dank-ai

# 3. The template already uses the correct import
# const { createAgent } = require("dank");

# 4. Run your agents
dank run

🐳 Docker Architecture

Dank uses a layered Docker approach:

1. Base Image (deltadarkly/dank-agent-base): Common runtime with Node.js, LLM clients
2. Agent Images: Extend base image with agent-specific code and custom tags
3. Containers: Running instances with resource limits and networking

Container Features

• Isolated Environments: Each agent runs in its own container
• Resource Limits: Memory and CPU constraints per agent
• Health Monitoring: Built-in health checks and status reporting
• Automatic Restarts: Container restart policies for reliability
• Logging: Centralized log collection and viewing

🚀 Automatic Docker Management

Dank automatically handles Docker installation and startup for you:

Auto-Detection & Installation

When you run any Dank command, it will:

1. Check if Docker is installed - Runs docker --version to detect installation
2. Install Docker if missing - Automatically installs Docker for your platform:
   • macOS: Uses Homebrew to install Docker Desktop
   • Linux: Installs Docker CE via apt package manager
   • Windows: Uses Chocolatey to install Docker Desktop
3. Start Docker if stopped - Automatically starts Docker service
4. Wait for availability - Ensures Docker is ready before proceeding

Platform-Specific Installation

macOS:

# Dank will automatically run:
brew install --cask docker
open -a Docker

Linux (Ubuntu/Debian):

# Dank will automatically run:
sudo apt-get update
sudo apt-get install -y docker-ce docker-ce-cli containerd.io
sudo systemctl start docker
sudo systemctl enable docker
sudo usermod -aG docker $USER

Windows:

# Dank will automatically run:
choco install docker-desktop -y
start "" "C:\Program Files\Docker\Docker\Docker Desktop.exe"

Manual Fallback

If automatic installation fails, Dank will provide clear instructions:

# Example output when manual installation is needed
❌ Docker installation failed: Homebrew not found
💡 Please install Docker Desktop manually from:
   https://www.docker.com/products/docker-desktop/

Status Messages

Dank provides clear feedback during the process:

Step-by-Step Integration Guide

1. Project Setup

# In your existing project directory
npm install -g dank-ai

# Initialize Dank configuration
dank init

# This creates dank.config.js in your current directory

2. Basic Agent Configuration

Start with a simple agent configuration in dank.config.js:

const { createAgent } = require('dank');

module.exports = {
  name: 'my-project',
  
  agents: [
    // Simple assistant agent
    createAgent('helper')
      .setLLM('openai', {
        apiKey: process.env.OPENAI_API_KEY,
        model: 'gpt-3.5-turbo'
      })
      .setPrompt('You are a helpful assistant.')
      .addHandler('output', console.log)
  ]
};

3. Multi-Agent Setup

Configure multiple specialized agents:

const { createAgent } = require('dank');

module.exports = {
  name: 'multi-agent-system',
  
  agents: [
    // Customer service agent
    createAgent('customer-service')
      .setLLM('openai', {
        apiKey: process.env.OPENAI_API_KEY,
        model: 'gpt-3.5-turbo',

      })
      .setPrompt(`
        You are a friendly customer service representative.
        - Be helpful and professional
        - Resolve customer issues quickly
        - Escalate complex problems appropriately
      `)
      .setInstanceType('small')
      .addHandler('output', (data) => {
        console.log('[Customer Service]:', data);
        // Add your business logic here
      }),

    // Data analyst agent
    createAgent('analyst')
      .setLLM('openai', {
        apiKey: process.env.OPENAI_API_KEY,
        model: 'gpt-4',
        temperature: 0.3
      })
      .setPrompt(`
        You are a data analyst expert.
        - Analyze trends and patterns
        - Provide statistical insights
        - Create actionable recommendations
      `)
      .setInstanceType('medium')
      .addHandler('output', (data) => {
        console.log('[Analyst]:', data);
        // Save analysis results to database
      }),

    // Content creator agent
    createAgent('content-creator')
      .setLLM('anthropic', {
        apiKey: process.env.ANTHROPIC_API_KEY,
        model: 'claude-3-sonnet-20240229'
      })
      .setPrompt(`
        You are a creative content writer.
        - Write engaging, original content
        - Adapt tone to target audience
        - Follow brand guidelines
      `)
      .setInstanceType('small')
      .addHandler('output', (data) => {
        console.log('[Content Creator]:', data);
        // Process and publish content
      })
  ]
};

🎯 Common Use Cases

Use Case 1: Customer Support Automation

createAgent('support-bot')
  .setLLM('openai', {
    apiKey: process.env.OPENAI_API_KEY,
    model: 'gpt-3.5-turbo'
  })
  .setPrompt(`
    You are a customer support specialist for [Your Company].
    
    Guidelines:

    .setPrompt('Optimize content for SEO and readability')
    .addHandler('output', (optimizedContent) => {
      // Publish optimized content
      publishContent(optimizedContent);
    })
];

Use Case 3: Data Analysis Workflow

createAgent('data-processor')
  .setLLM('openai', {
    apiKey: process.env.OPENAI_API_KEY,
    model: 'gpt-4',
    temperature: 0.1  // Low temperature for consistent analysis
  })
  .setPrompt(`
    You are a data analyst. Analyze the provided data and:
    1. Identify key trends and patterns
    2. Calculate important metrics
    3. Provide actionable insights
    4. Format results as JSON
  `)
  .setInstanceType('large')  // More memory for data processing
  .addHandler('output', (analysis) => {
    try {
      const results = JSON.parse(analysis);
      // Store results in database
      saveAnalysisResults(results);
      // Generate reports
      generateReport(results);
      // Send alerts if thresholds are met
      checkAlerts(results);
    } catch (error) {
      console.error('Failed to parse analysis:', error);
    }
  });

🔧 Advanced Configuration

Custom Agent Code

For complex logic, create custom agent files in the agents/ directory:

// agents/custom-agent.js
module.exports = {
  async main(llmClient, handlers) {
    console.log('Custom agent starting...');
    
    // Your custom agent logic
    setInterval(async () => {
      try {
        // Make LLM request
        const response = await llmClient.chat.completions.create({
          model: 'gpt-3.5-turbo',
          messages: [
            { role: 'system', content: 'You are a helpful assistant' },
            { role: 'user', content: 'Generate a daily report' }
          ]
        });
        
        // Trigger output handlers
        const outputHandlers = handlers.get('output') || [];
        outputHandlers.forEach(handler => 
          handler(response.choices[0].message.content)
        );
        
      } catch (error) {
        // Trigger error handlers
        const errorHandlers = handlers.get('error') || [];
        errorHandlers.forEach(handler => handler(error));
      }
    }, 60000); // Run every minute
  },
  
  // Define custom handlers
  handlers: {
    output: [
      (data) => console.log('Custom output:', data)
    ],
    error: [
      (error) => console.error('Custom error:', error)
    ]
  }
};

Environment-Specific Configuration

// dank.config.js
const { createAgent } = require('dank');

const isDevelopment = process.env.NODE_ENV === 'development';
const isProduction = process.env.NODE_ENV === 'production';

module.exports = {
  name: 'my-project',
  
  agents: [
    createAgent('main-agent')
      .setLLM('openai', {
        apiKey: process.env.OPENAI_API_KEY,
        model: isDevelopment ? 'gpt-3.5-turbo' : 'gpt-4',
        temperature: isDevelopment ? 0.9 : 0.7
      })
      .setInstanceType(isDevelopment ? 'small' : 'medium')
      .addHandler('output', (data) => {
        if (isDevelopment) {
          console.log('DEV:', data);
        } else {
          // Production logging
          logger.info('Agent output', { data });
        }
      })
  ]
};

🚨 Troubleshooting

Common Issues and Solutions

1. Docker Connection Issues

# Error: Cannot connect to Docker daemon
# Solution: Dank will automatically handle this!

# If automatic installation fails, manual steps:
docker --version
docker ps

# On macOS/Windows: Start Docker Desktop manually
# On Linux: Start Docker service
sudo systemctl start docker

1a. Docker Installation Issues

# If automatic installation fails, try manual installation:

# macOS (with Homebrew):
brew install --cask docker
open -a Docker

# Linux (Ubuntu/Debian):
sudo apt-get update
sudo apt-get install -y docker-ce docker-ce-cli containerd.io
sudo systemctl start docker
sudo usermod -aG docker $USER

# Windows (with Chocolatey):
choco install docker-desktop -y
# Then start Docker Desktop from Start Menu

2. API Key Issues

# Error: Invalid API key
# Solution: Check your environment variables
echo $OPENAI_API_KEY

# Set the key properly
export OPENAI_API_KEY="sk-your-actual-key-here"

# Or create a .env file in your project
echo "OPENAI_API_KEY=sk-your-actual-key-here" > .env

3. Base Image Not Found

# Error: Base image 'deltadarkly/dank-agent-base' not found
# Solution: The base image is pulled automatically, but you can build it manually
# ty also pulling manually when docker is running  via docker pull <image name>
dank build --base

4. Container Resource Issues

# Error: Container exits with code 137 (out of memory)
# Solution: Increase memory allocation (On cloud service, on local agents run with given resources)
createAgent('my-agent')
  .setInstanceType('medium')  // Increase from 'small' to 'medium'

5. Agent Not Starting

# Check agent logs for detailed error information
dank logs agent-name

# Check container status
docker ps -f name=dank-

# View Docker logs directly
docker logs container-id

💡 Best Practices

1. Resource Management

// Good: Appropriate resource allocation
createAgent('light-agent')
  .setInstanceType('small');  // Light tasks

createAgent('heavy-agent')
  .setInstanceType('large');  // Heavy processing

2. Error Handling

// Good: Comprehensive error handling
createAgent('robust-agent')
  .addHandler('error', (error) => {
    console.error('Agent error:', error.message);
    
    // Log to monitoring system
    logError(error);
    
    // Send alert if critical
    if (error.type === 'CRITICAL') {
      sendAlert(error);
    }
    
    // Implement retry logic
    scheduleRetry(error.context);
  })
  .addHandler('output', (data) => {
    try {
      processOutput(data);
    } catch (error) {
      console.error('Output processing failed:', error);
    }
  });

3. Environment Configuration

// Good: Environment-specific settings
const config = {
  development: {
    model: 'gpt-3.5-turbo',
    memory: '256m',
    logLevel: 'debug'
  },
  production: {
    model: 'gpt-4',
    memory: '1g',
    logLevel: 'info'
  }
};

const env = process.env.NODE_ENV || 'development';
const settings = config[env];

createAgent('environment-aware')
  .setLLM('openai', {
    model: settings.model,
    temperature: 0.7
  })
  .setInstanceType(settings.instanceType || 'small')
  });

4. Monitoring and Logging

// Good: Structured logging
createAgent('monitored-agent')
  .addHandler('output', (data) => {
    logger.info('Agent output', {
      agent: 'monitored-agent',
      timestamp: new Date().toISOString(),
      data: data.substring(0, 100) // Truncate for logs
    });
  })
  .addHandler('error', (error) => {
    logger.error('Agent error', {
      agent: 'monitored-agent',
      error: error.message,
      stack: error.stack
    });
  })
  .addHandler('start', () => {
    logger.info('Agent started', { agent: 'monitored-agent' });
  });

5. Security Considerations

// Good: Secure configuration
createAgent('secure-agent')
  .setLLM('openai', {
    apiKey: process.env.OPENAI_API_KEY, // Never hardcode keys
    model: 'gpt-3.5-turbo'
  })
  .setPrompt(`
    You are a helpful assistant.
    
    IMPORTANT SECURITY RULES:
    - Never reveal API keys or sensitive information
    - Don't execute system commands
    - Validate all inputs before processing
    - Don't access external URLs unless explicitly allowed
  `)
  .addHandler('output', (data) => {
    // Sanitize output before logging
    const sanitized = sanitizeOutput(data);
    console.log(sanitized);
  });

1. Parallel Agent Management

// Good: Balanced agent distribution
module.exports = {
  agents: [
    // CPU-intensive agents
    createAgent('analyzer').setInstanceType('medium'),
    
    // Memory-intensive agents  
    createAgent('processor').setInstanceType('large'),
    
    // Light agents
    createAgent('notifier').setInstanceType('small')
  ]
};

2. Efficient Prompt Design

// Good: Clear, specific prompts
.setPrompt(`
  You are a customer service agent. Follow these steps:
  
  1. Greet the customer politely
  2. Understand their issue by asking clarifying questions
  3. Provide a solution or escalate if needed
  4. Confirm resolution
  
  Response format: JSON with fields: greeting, questions, solution, status
`);

🔄 Development Workflow

1. Local Development

# 1. Start with development configuration
NODE_ENV=development dank run

# 2. Make changes to dank.config.js

# 3. Restart agents to apply changes
dank stop --all
dank run --build  # Rebuild if needed
