Example: RAG Orchestrator

Complete implementation of a RAG orchestrator in both natural language and SNS notation.

The Task

The orchestrator is the first stage in a 3-stage RAG pipeline. Its job:

Analyze the user's query
Extract keywords
Classify the user's intent
Expand the query into search terms
Infer relevant knowledge base categories
Apply boosts if needed
Return structured search parameters

Traditional Natural Language Implementation

You are the orchestrator in a 3-stage RAG system for a municipal knowledge base.

Your role is to analyze incoming user queries and prepare optimized search parameters 
for the retrieval system.

Please perform the following steps:

1. Extract Keywords: Analyze the user query and extract the main keywords and important 
   terms. Focus on nouns, verbs, and domain-specific terminology.

2. Classify Intent: Determine the user's primary intent. Classify into one of these 
   categories:
   - "information": User is seeking information or asking a question
   - "complaint": User is reporting a problem or filing a complaint
   - "procedure": User wants to know how to do something

3. Expand Query: Using the extracted keywords and the detected intent as context, expand 
   the query into related search terms. Include synonyms, related concepts, and domain-specific 
   terminology that will improve retrieval.

4. Infer Categories: Based on the detected intent and query content, infer which knowledge 
   base categories are most relevant. Categories include:
   - bylaws/noise
   - bylaws/zoning
   - bylaws/business
   - procedures/permits
   - procedures/tax
   - information/services
   - enforcement/complaints

5. Apply Boosts: If the intent is "complaint", apply a recency boost to prioritize recent 
   documents. If the query mentions specific locations, apply a location boost.

6. Return Results: Return a structured object containing:
   - search_terms: List of expanded search terms
   - categories: List of relevant knowledge base categories
   - intent: The classified intent
   - keywords: Original extracted keywords
   - boosts: Object containing boost parameters

Please process the following query: {USER_QUERY}

Return your analysis as a structured JSON object.

SNS Implementation

# RAG Orchestrator

# Extract & classify
q → kw_extract → kw
q → classify(["info","complaint","procedure"]) → intent

# Expand with context
(kw + q + intent) → expand_q → search_terms

# Infer categories
intent + q → infer_cats → cats

# Apply conditional boosts
boosts = {
  recency: intent == "complaint",
  location: has_location(q)
}

# Return search params
→ {
  search_terms,
  categories: cats,
  intent,
  keywords: kw,
  boosts
}

Token Count: ~62 tokens

Savings: 85% (358 tokens saved)

With Creative Notation (Emoji)

# RAG Orchestrator 🎯

# Analyze query
q 🔍 analyze → {kw, intent}

# Expand & target
kw + intent → expand_q → search_terms
intent 🎯 infer_cats → cats

# Boost if needed
intent == "complaint" ? search_terms ⚡ boost(recency) : search_terms
has_location(q) ? search_terms 🎯 boost(location) : search_terms

# Package results
📦 {
  search_terms,
  cats,
  intent,
  kw,
  urgent: intent == "complaint" 🚨
}

Token Count: ~55 tokens

Savings: 87% (365 tokens saved)

Real Query Examples

Example 1: Noise Complaint

User Query: "my neighbor is too loud at night"

Traditional Output (from 420 token prompt):

{
  "keywords": ["neighbor", "loud", "night"],
  "intent": "complaint",
  "search_terms": ["noise", "bylaw", "residential", "quiet hours", 
                   "noise control", "neighbor", "night", "disturbance"],
  "categories": ["bylaws/noise", "enforcement/complaints"],
  "boosts": {
    "recency": true,
    "location": false
  }
}

SNS Output (from 62 token prompt):

{
  "keywords": ["neighbor", "loud", "night"],
  "intent": "complaint",
  "search_terms": ["noise", "bylaw", "residential", "quiet hours",
                   "noise control", "neighbor", "night", "disturbance"],
  "categories": ["bylaws/noise", "enforcement/complaints"],
  "boosts": {
    "recency": true,
    "location": false
  }
}

Result: Identical output, 85% fewer tokens

Example 2: Information Request

User Query: "how do I pay my property tax?"

SNS Processing:

q = "how do I pay my property tax?"

# Extract & classify
q → kw_extract → ["pay", "property", "tax"]
q → classify(intents) → "information"

# Expand
["pay", "property", "tax"] + "information" 
  → expand_q 
  → ["payment", "property tax", "pay", "methods", 
      "online payment", "tax payment", "municipal tax"]

# Infer categories
"information" + q → infer_cats → ["procedures/tax", "information/services"]

# No boosts for info requests
boosts = {recency: false, location: false}

→ {
  search_terms: [...],
  categories: ["procedures/tax", "information/services"],
  intent: "information",
  keywords: ["pay", "property", "tax"],
  boosts: {recency: false, location: false}
}

Example 3: Procedure Question

User Query: "what do i need to start a food truck"

SNS Processing:

q = "what do i need to start a food truck"

q → kw_extract → ["need", "start", "food truck"]
q → classify(intents) → "procedure"

["need", "start", "food truck"] + "procedure"
  → expand_q
  → ["business license", "food truck", "mobile vendor", 
      "permit", "requirements", "food service", "startup"]

"procedure" + q → infer_cats 
  → ["bylaws/business", "procedures/permits", "information/services"]

→ {
  search_terms: [...],
  categories: ["bylaws/business", "procedures/permits", "information/services"],
  intent: "procedure",
  keywords: ["need", "start", "food truck"],
  boosts: {recency: false, location: false}
}

Token Count: ~20 tokens
Savings: 95%
Tradeoff: Less readable, but LLMs still understand

Verbose SNS (More explicit)

# Extract keywords

# Classify user intent
query → classify(intent_types) → intent

# Expand into search terms
keywords + query + intent → expand_query → search_terms

# Infer relevant categories
intent + query → infer_categories → categories

# Determine boost parameters
boosts = {
  recency: intent == "complaint",
  location: has_location_mention(query)
}

# Return structured params
return {
  search_terms: search_terms,
  categories: categories,
  intent: intent,
  keywords: keywords,
  boosts: boosts
}

Token Count: ~95 tokens
Savings: 77%
Tradeoff: More readable, still major savings

With Comments (Hybrid)

# RAG Orchestrator - prepares search params from user query

# Step 1: Extract and classify

# Step 3: Infer categories
intent + q → infer_cats → cats   # Map to KB categories

# Step 4: Apply boosts

Integration Example

TypeScript Integration

// Define orchestrator prompt in SNS
const orchestratorPrompt = `
# RAG Orchestrator

q → kw_extract → kw
q → classify(["info","complaint","procedure"]) → intent
(kw + q + intent) → expand_q → search_terms
intent + q → infer_cats → cats

boosts = {
  recency: intent == "complaint",
  location: has_location(q)
}

→ {search_terms, cats, intent, kw, boosts}

q = "${userQuery}"
`;

// Call LLM
const response = await ollama.generate({
  model: "llama3.2:3b",
  prompt: orchestratorPrompt,
  format: "json"
});

// Parse result
const searchParams = JSON.parse(response.response);

// Use in retrieval
const results = await vectorSearch({
  terms: searchParams.search_terms,
  categories: searchParams.categories,
  boosts: searchParams.boosts
});

Best Practices from This Example

Group related operations: Extract and classify together
Use composition: (kw + q + intent) → expand_q
Inline conditionals: intent == "complaint" ? boost : no_boost
Structured returns: Clear object structure
