     • Static analysis
     • Performance analysis
     • Memory analysis
     • Complexity analysis
     • Security analysis
     • Dependency analysis
     • Coverage analysis

Prompt System

Echo uses a dynamic, file-based prompt system that significantly enhances its flexibility and maintainability:

Key Features

• Template-Based: Prompts are stored as template files with the .echo extension
• Context-Aware: Templates can include variables, conditionals, and loops
• Centralized Management: All prompts are managed by the promptService
• Extensible: New templates can be added without code changes
• Versioned: Templates are stored in version control for tracking changes
• Hot-Reloadable: Templates can be reloaded without restarting the service

Prompt Selection Logic

The system automatically selects the most appropriate prompt based on:

1. Message context (DM vs. server)
2. Detected entities (users, channels, roles)
3. Message type (conversation, technical, knowledge, etc.)
4. Agent type (which specialized agent is handling the request)

For complete details, see Prompt System Documentation.

System Integration

Agent Collaboration Patterns

The agents in Echo work together through several collaboration patterns:

1. Sequential Processing

   • Message is classified and routed to the most appropriate agent
   • If the primary agent needs help, it can delegate to other agents

2. Research Augmentation

   • Knowledge and Support agents can request research assistance
   • Research agent enhances responses with external information
   • Results are integrated into the final response

3. Background Research

   • For certain conversation types, research happens in the background
   • Results are cached for future related questions
   • Improves response quality without increasing latency

4. Context Sharing

   • Agents share context about the conversation
   • Previous interactions inform current responses
   • User preferences and history are maintained across agents

Loading

Response Format

interface AgentResponse {
    content: string // Main response content
    needsResearch?: boolean // External research flag
    searchQuery?: string // Research query
    error?: string // Error information
    metadata?: object // Additional context
    confidence: number // Response confidence score
    source?: string // Information source
    sourceResults?: Array<{
        title: string
        link: string
        snippet: string
    }> // Research sources
}

Performance Optimization

Response Caching

Echo implements an intelligent caching system to improve response times:

// Generate a cache key for responses
_generateCacheKey = (prompt, context) => {
    // Normalize prompt by trimming, lowercasing, and removing extra spaces
    const normalizedPrompt = prompt.trim().toLowerCase().replace(/\s+/g, ' ')

    // Don't cache complex or personalized queries
    if (
        prompt.length > 150 ||
        context.personalData ||
        normalizedPrompt.includes('my ') ||
        normalizedPrompt.includes('I ')
    ) {
        return null
    }

    // Create a stable key from the normalized prompt
    return `response:${normalizedPrompt}`
}

Serialization

To prevent circular reference errors, all complex objects are serialized before being passed to the AI model:

// Before passing to AI model
const safeObject = makeSerializable(complexObject)

Background Processing

Non-blocking operations are used for improved responsiveness:

// Start background research without blocking the response
_performBackgroundResearch = async (prompt, userId) => {
    try {
        // Start research in the background
        const researchResults = await this.researchAgent.process(prompt, userId)

        // Store the results for potential future use
        this._cacheResearchResults(userId, prompt, researchResults)
    } catch (error) {
        console.error('Background research failed:', error)
    }
}
