Agent-Based Task Execution – onprem

18 min read Original article ↗

This notebook demonstrates how to use the Agent pipeline from OnPrem.LLM to create autonomous agents that can execute complex tasks using a variety of tools.

The pipeline works with any LiteLLM-supported model that supports tool-calling:

  • Cloud: openai/gpt-5.2-codex, anthropic/claude-sonnet-4-5, gemini/gemini-1.5-pro
  • Local: Ollama (ollama/llama3.1), vLLM (hosted_vllm/), llama.cpp (use OpenAI interface)

For llama.cpp: Use openai/<model_name> (e.g., gpt-oss-120b) as model parameter and then set env variable OPENAI_API_BASE=http://localhost:<port>/v1

The AgentExecutor

The AgentExecutor allows you to launch AI agents to solve various tasks using both cloud and local models. We will use anthropic/claude-sonnet-4-5 (cloud) and glm-4.7-flash (local) for these examples.

By default, the AgentExecutor has access to 9 built-in tools. You remove access to built-in-tools as necessary. You can optionally give the agent access to custom tools, as we’ll illustrate below.

The AgentExecutor is implemented using our coding agent, PatchPal, which you’ll need to install: pip install patchpal.

from onprem.pipelines import AgentExecutor
AgentExecutor.print_default_tools()
======================================================================
AgentExecutor Default Tools
======================================================================

These tools are used by default when enabled_tools=None:

   1. read_file       - Read complete file contents
   2. read_lines      - Read specific line ranges from files
   3. edit_file       - Edit files via find/replace
   4. write_file      - Write complete file contents
   5. grep            - Search for patterns in files
   6. find            - Find files by glob pattern
   7. run_shell       - Execute shell commands
   8. web_search      - Search the web for information
   9. web_fetch       - Fetch and read content from URLs

======================================================================
Customization Examples:
======================================================================

# Use defaults (all tools including shell):
executor = AgentExecutor(model='anthropic/claude-sonnet-4-5')

# Defaults but no shell access (safer):
executor = AgentExecutor(
    model='openai/gpt-5-mini',
    disable_shell=True
)

# Minimal tools:
executor = AgentExecutor(
    model='openai/gpt-5-mini',
    enabled_tools=['read_file', 'write_file']
)

# Web research only:
executor = AgentExecutor(
    model='openai/gpt-5-mini',
    enabled_tools=['web_search', 'web_fetch']
)

Examples

Let’s run through some examples for different scenarios.

Basic Calculator Example

In this introductory example, we will launch an agent to build a calculator module in Python.

By default, the agent will operate within the working_directory you specify (or the current folder if not working directory is specified). The agent cannot read or write outside the working directory.

Important Note:: If the agent has access to the run_shell tool, it can potentially read or modify files outside of the working directory (e.g., auto-generating and executing a Python script that writes files outside of working directory). For these reasons, you can either supply the disable_shell=True to remove shell access or sandbox=True, which runs the agent in an ephemeral container.

In this first example, we set sandbox=True. The example was run on Windows Subsystem for Linux (WSL) with PodMan installed. We will cover sandboxed execution in more detail later.

executor = AgentExecutor(
     model='anthropic/claude-sonnet-4-5', # assumes ANTHROPIC_API_KEY is already set as environment variable
     sandbox=True,
     
 )

result = executor.run(
     task="""

Quantum Computing in 2026: A Comprehensive Report

Date: March 17, 2026

Executive Summary

Quantum computing has reached a critical inflection point in 2026, transitioning from laboratory research to commercial deployment and real-world infrastructure. The field is experiencing unprecedented convergence across multiple dimensions: fault-tolerant logical qubits, quantum networking capabilities, and hybrid quantum-classical integration through GPU control systems.

Key Highlights:

  • Hardware Scaling: IBM's 1,121-qubit Condor processor represents a major milestone in superconducting quantum systems (unveiled December 2023), Google's 105-qubit Willow chip has demonstrated breakthrough error correction capabilities (December 2024), and Caltech researchers have achieved a record-breaking 6,100-qubit neutral-atom array with 99.98% accuracy (September 2025). Among commercial systems, Atom Computing's 1,225-qubit neutral-atom machines represent notable availability, though research systems now significantly exceed this scale.

  • Global Investment: The quantum computing market has reached \$17.3 billion in 2026, up from \$2.1 billion in 2022—a 65% year-over-year increase reflecting enterprise confidence in near-term quantum advantage.

  • Infrastructure Convergence: The industry has shifted from isolated quantum systems to integrated hybrid architectures that combine quantum processors with high-performance classical computing, marking the beginning of the "hybrid era."

  • Major Breakthroughs: Recent advances span reliability improvements (logical qubits with error correction), quantum networking milestones (device-independent quantum key distribution over 100km), hybrid GPU control systems (NVIDIA's NVQLink enabling microsecond-latency feedback loops), and record-breaking qubit arrays demonstrating unprecedented scale and coherence.

Local Models

The AgentExecutor supports local models. By default, it will assume the local model supports native function-calling (e.g., gpt-oss-120b). If you use a local model that does not have good native support for function-calling (a.k.a. tool-calling), you can change the agent_type to react. In this example, we will use glm-4.7-flash.

Note: The default context window length in Ollama is typically too small for agentic workflows. Depending on the model and task, we recommend inreasing to at least 8192. Reasoning models like gpt-oss:120b may require 32K or 64K.

### Local Models + Sandbox: Networking Setup

Local models (Ollama, llama.cpp) on localhost need container networking configured:

  • Linux/WSL2: Supply network='host' to AgentExecutor. (WSL2: make sure to enable mirrored networking in .wslconfig.)
  • macOS/Windows: Set OLLAMA_API_BASE='http://host.docker.internal:11434' (Docker) or http://host.containers.internal:11434 (Podman)

Custom Tools

You can give the agent custom tools by simply defining them as Python functions or callables.

In this example, we’ll build a financial analysis agent with custom tools.

Let’s first define the custom tools, which are based on yfinance.

pip install yfinance

Step 1: Define the custom tools as Python functions

from typing import List, Dict
from datetime import datetime, timedelta

# Define custom financial tools


def get_current_stock_price(ticker: str) -> Dict[str, float]:
    """
    Fetch current/live stock price for a given ticker.
    
    Args:
        ticker: Stock ticker symbol (e.g., 'AAPL', 'GOOGL')
     Returns:
        Dictionary with current price and related info
    """
    try:
        import yfinance as yf
        from datetime import datetime
        stock = yf.Ticker(ticker)
        info = stock.info

        # Get current price (live during market hours, last close otherwise)
        current_price = info.get('currentPrice') or info.get('regularMarketPrice')

        return {
            "ticker": ticker.upper(),
            "current_price": round(current_price, 2),
            "market_state": info.get('marketState', 'unknown'),  # 'REGULAR', 'CLOSED', etc.
            "timestamp": datetime.now().isoformat()
        }
    except Exception as e:
        return {"error": str(e)}


def calculate_return_percentage(purchase_price: float, current_price: float) -> float:
     """
     Calculate percentage return on investment.
    
     Args:
         purchase_price: Original purchase price per share
         current_price: Current market price per share
    
     Returns:
         Percentage return (positive for gains, negative for losses)
     """
     if purchase_price == 0:
         return 0.0
     return round(((current_price - purchase_price) / purchase_price) * 100, 2)

def analyze_volatility(ticker: str, days: int = 30) -> Dict[str, float]:
     """
     Calculate stock volatility metrics over a period.
    
     Args:
         ticker: Stock ticker symbol
         days: Number of days to analyze
    
     Returns:
         Dictionary with volatility metrics
     """
     try:
         import yfinance as yf
         stock = yf.Ticker(ticker)
         end_date = datetime.now()
         start_date = end_date - timedelta(days=days + 10)
         hist = stock.history(start=start_date, end=end_date)
    
         if hist.empty or len(hist) < 2:
             return {"error": f"Insufficient data for {ticker}"}
    
         daily_changes = hist['Close'].pct_change() * 100
    
         return {
             "ticker": ticker.upper(),
             "period_days": len(hist),
             "avg_daily_change": round(abs(daily_changes.mean()), 2),
             "max_increase": round(daily_changes.max(), 2),
             "max_decrease": round(daily_changes.min(), 2),
             "std_deviation": round(daily_changes.std(), 2)
         }
     except Exception as e:
         return {"error": str(e)}

Step 2: Launch the agent with access to the custom tools

# Create agent with custom tools
from onprem.pipelines.agent import AgentExecutor

executor = AgentExecutor(
 model='anthropic/claude-sonnet-4-5',
 custom_tools=[calculate_return_percentage, analyze_volatility, get_current_stock_price],
 enabled_tools=['write_file'],
 verbose=True
)

# Task: Analyze Apple and Microsoft stock
task = """

I'll create a comprehensive stock analysis report for Apple and Microsoft. Let  
me gather the data first.

🔧 analyze_volatility({'ticker': 'AAPL', 'days': 30})
🔧 analyze_volatility({'ticker': 'MSFT', 'days': 30})

Now let me calculate the return percentage for the AAPL investment:             

🔧 calculate_return_percentage({'purchase_price': 150, 'current_price': 254.46})
