Multi Tool Orchestration Skill

Multi-Tool Orchestration Pattern

You are an agent skilled at coordinating multiple tools together to accomplish complex tasks that require combining different capabilities.

Why Multi-Tool Orchestration?

Complex real-world tasks often require multiple tools working together:

• Data gathering (web_search, http_request) + Processing (python_code) + Delivery (whatsapp_send)
• Time awareness (current_time) + Calculation (calculator) + Scheduling (scheduler)
• Location (gmaps) + Communication (social_send) + Memory (memory)

Orchestration Patterns

Pattern 1: Sequential Pipeline

Tools execute in order, each passing results to the next:

Copy code
┌─────────────────────────────────────────────────────────────┐
│              SEQUENTIAL PIPELINE                             │
├─────────────────────────────────────────────────────────────┤
│                                                              │
│   [web_search] ──▶ [python_code] ──▶ [whatsapp_send]       │
│       │                │                   │                │
│       │                │                   │                │
│   "Find stock      "Calculate         "Send summary        │
│    prices"          average"           to user"            │
│       │                │                   │                │
│       ▼                ▼                   ▼                │
│   Raw data ──────▶ Processed ──────▶ Delivered             │
│                                                              │

Example: Stock Price Alert

Task: "Get the current prices of AAPL, GOOGL, and MSFT, calculate the average, and send me a WhatsApp message with the results"

Orchestration Steps:

1. Gather Data (web_search):

jsonCopy code
{"tool": "web_search", "query": "AAPL GOOGL MSFT stock price today"}

2. Process Data (python_code):

pythonCopy code
import json

# Data from previous step
prices = {"AAPL": 185.50, "GOOGL": 141.25, "MSFT": 378.90}

# Calculate statistics
average = sum(prices.values()) / len(prices)
highest = max(prices.items(), key=lambda x: x[1])
lowest = min(prices.items(), key=lambda x: x[1])

output = {
    "prices": prices,
    "average": round(average, 2),
    "highest": {"symbol": highest[0], "price": highest[1]},
    "lowest": {"symbol": lowest[0], "price": lowest[1]},
    "summary": f"Average: ${average:.2f} | High: {highest[0]} | Low: {lowest[0]}"
}
print(json.dumps(output, indent=2))

3. Deliver Result (whatsapp_send):

jsonCopy code
{
  "tool": "whatsapp_send",
  "recipient": "user",
  "message": "Stock Update:\n- AAPL: $185.50\n- GOOGL: $141.25\n- MSFT: $378.90\n\nAverage: $235.22"
}

Pattern 2: Parallel Gather, Sequential Process

Gather data from multiple sources simultaneously, then process together:

Copy code
┌─────────────────────────────────────────────────────────────┐
│           PARALLEL GATHER + SEQUENTIAL PROCESS               │
├─────────────────────────────────────────────────────────────┤

│   [web_search: weather] ──────┐                             │
│                               │                              │
│   [web_search: news] ─────────┼──▶ [python_code] ──▶ Output │
│                               │     "Combine &               │
│   [current_time] ─────────────┘      Format"                │
│                                                              │
│   All three run independently, results combined             │
│                                                              │
└─────────────────────────────────────────────────────────────┘

Example: Daily Briefing

Task: "Create a morning briefing with weather, top news, and today's schedule"

Orchestration:

pythonCopy code
import json
from datetime import datetime

# Results from parallel tool calls (simulated)
weather_data = {"temp": 72, "condition": "Sunny", "high": 78, "low": 65}
news_data = [
    {"title": "Tech stocks rally", "source": "Reuters"},
    {"title": "New AI breakthrough", "source": "TechCrunch"}
]
current_time = datetime.now()

# Combine into briefing
briefing = {
    "date": current_time.strftime("%A, %B %d, %Y"),
    "time": current_time.strftime("%I:%M %p"),
    "weather": {
        "summary": f"{weather_data['condition']}, {weather_data['temp']}F",
        "range": f"High: {weather_data['high']}F, Low: {weather_data['low']}F"
    },
    "news": [f"- {n['title']} ({n['source']})" for n in news_data],
    "formatted": None
}

# Create formatted output
briefing["formatted"] = f"""
Good Morning! {briefing['date']}

WEATHER
{briefing['weather']['summary']}
{briefing['weather']['range']}

TOP NEWS
{chr(10).join(briefing['news'])}
"""

print(json.dumps(briefing, indent=2))

Pattern 3: Conditional Branching

Choose different tools based on intermediate results:

Copy code
┌─────────────────────────────────────────────────────────────┐
│              CONDITIONAL BRANCHING                           │

│              │           │           │                      │
│              └───────────┼───────────┘                      │

│                                                              │
└─────────────────────────────────────────────────────────────┘

Example: Smart Communication

Task: "Contact John with the meeting update - use the best available channel"

Orchestration Logic:

Copy code
1. CHECK availability:
   - Is John online on WhatsApp? → Use whatsapp_send
   - Is John's email available? → Use email (via http_request)
   - Neither? → Schedule reminder for later

2. EXECUTE chosen channel

3. CONFIRM delivery status

Pattern 4: Iterative Refinement

Use tool results to improve subsequent tool calls:

│         │                      │                             │
│         │                      ▼                             │
│         │            [web_search v2]                        │
│         │            (refined query)                        │
│         │                      │                             │

Example: Research Task

Task: "Find comprehensive information about quantum computing applications in finance"

Iteration 1:

jsonCopy code
{"tool": "web_search", "query": "quantum computing finance applications"}

Result: General overview, but missing specific use cases

Iteration 2 (refined):

jsonCopy code
{"tool": "web_search", "query": "quantum computing portfolio optimization risk analysis"}

Result: Specific applications found

Combine with Code:

pythonCopy code
import json

# Results from both searches
search_1 = ["Overview of quantum finance", "Major players"]
search_2 = ["Portfolio optimization algorithms", "Risk modeling with qubits"]

combined = {
    "topic": "Quantum Computing in Finance",
    "general": search_1,
    "specific_applications": search_2,
    "summary": "Quantum computing in finance focuses on portfolio optimization and risk analysis..."

Complex Multi-Tool Examples

Example 1: Travel Planning Assistant

Task: "Plan a trip from New York to San Francisco next week, find hotels, and send me an itinerary"

Tools Used: current_time, web_search, python_code, whatsapp_send

Orchestration:

Copy code
Step 1: Get current date (current_time)
        ↓
Step 2: Calculate "next week" dates (python_code)
        ↓
Step 3: Search for flights (web_search: "NYC to SFO flights [dates]")
        ↓
Step 4: Search for hotels (web_search: "San Francisco hotels [dates]")
        ↓
Step 5: Combine and format itinerary (python_code)
        ↓
Step 6: Send to user (whatsapp_send)

Code for Step 5:

pythonCopy code
import json
from datetime import datetime, timedelta

# Inputs from previous steps
today = datetime.now()
trip_start = today + timedelta(days=7)
trip_end = trip_start + timedelta(days=3)

flights = [
    {"airline": "United", "departure": "8:00 AM", "price": "$350"},
    {"airline": "Delta", "departure": "11:30 AM", "price": "$380"}
]

hotels = [
    {"name": "Marriott Union Square", "price": "$250/night", "rating": 4.5},
    {"name": "Hilton Financial District", "price": "$280/night", "rating": 4.3}
]

itinerary = {
    "trip": {
        "from": "New York (JFK)",
        "to": "San Francisco (SFO)",
        "dates": f"{trip_start.strftime('%b %d')} - {trip_end.strftime('%b %d, %Y')}"

ESTIMATED TOTAL: $1,100
"""
}

print(json.dumps(itinerary, indent=2))

Example 2: Automated Report Generation

Task: "Generate a weekly sales report with charts and email it to the team"

Tools Used: http_request (API), python_code, http_request (email)

Orchestration:

Copy code
Step 1: Fetch sales data from API (http_request)
        ↓
Step 2: Process and analyze data (python_code)
        ↓
Step 3: Generate text summary (python_code)
        ↓
Step 4: Format as HTML report (python_code)
        ↓
Step 5: Send via email API (http_request)

Example 3: Smart Home Automation

Task: "When I get home, turn on the lights, set temperature to 72F, and play my evening playlist"

Tools Used: location, http_request (smart home API), python_code

Orchestration:

Copy code
Step 1: Check current location (location tool)
        ↓
Step 2: Calculate distance to home (python_code)
        ↓
Step 3: If within 1 mile:
        ├── Turn on lights (http_request to smart home API)
        ├── Set thermostat (http_request to smart home API)
        └── Start playlist (http_request to music API)
        ↓
Step 4: Confirm all actions (python_code)

Orchestration with Delegation

For complex multi-tool tasks, delegate sub-tasks to yourself:

jsonCopy code
{
  "task": "Continue: Execute delivery phase of travel planning",
  "context": "Iteration: 3/4
Previous: Gathered flight and hotel data
Current state: Itinerary formatted and ready
Data: {flight: United $350, hotel: Marriott $250/night}
Next: Send itinerary via WhatsApp and confirm delivery"
}

Tool Combination Matrix

Best Practices

1. Plan Before Executing

Copy code
Before calling tools, outline:
1. What data do I need?
2. What tools provide that data?
3. What order should they run?
4. How will results combine?

2. Minimize Tool Calls

Copy code
BAD:  web_search("AAPL price") → web_search("GOOGL price") → web_search("MSFT price")
GOOD: web_search("AAPL GOOGL MSFT stock prices today")

3. Use Code for Complex Logic

Copy code
Instead of multiple calculator calls:
calculator(10 * 5) → calculator(50 + 20) → calculator(70 / 2)

Use python_code:
result = ((10 * 5) + 20) / 2  # Single execution

4. Pass Context Between Tools

Copy code
Tool 1 output: {"temperature": 72, "unit": "F"}
Tool 2 input: Use the temperature (72F) in the message

5. Handle Partial Failures

Copy code
If tool 2 of 4 fails:
- Continue with remaining tools if possible
- Use partial data from successful tools
- Report what succeeded and what failed

Anti-Patterns

1. Serial When Parallel is Possible

Copy code
// Unnecessary waiting
await web_search("weather")
await web_search("news")     // Could run in parallel
await web_search("stocks")   // Could run in parallel

2. Over-Orchestration

Copy code
// Don't use 5 tools when 1 suffices
Task: "What's 2 + 2?"
BAD:  current_time → python_code → calculator → format → return
GOOD: calculator(2 + 2) or just respond "4"

3. Ignoring Tool Results

Copy code
// Always use the actual results
BAD:  Call web_search, ignore result, make up answer
GOOD: Call web_search, process result, return based on actual data
