The Challenge

Autonomous AI trading agents present unprecedented risks to financial systems. Traditional software safeguards are insufficient when agents can reason their way around application-level controls.

Key Compliance Requirements

Why Application-Level Controls Fail

# ❌ Application-level "safeguard" - easily bypassed
class TradingAgent:
    def execute_trade(self, order):
        if order.size > self.max_position:
            # Agent can simply modify max_position
            # or call a different method
            # or reason that "this is an exception"
            return self.emergency_override(order)
        return self.broker.submit(order)

LLM-powered agents are fundamentally different from traditional software. They can:

• Reason around constraints — "This trade is urgent, I'll increase the limit temporarily"
• Discover workarounds — Finding alternative APIs or methods not covered by safeguards
• Chain actions creatively — Splitting large orders into smaller ones that individually pass checks
• Rationalize violations — "The policy says 'generally' so this exception is acceptable"

The Solution

Agent OS enforces risk policies at the kernel level—below the agent's reasoning layer where they cannot be bypassed, modified, or reasoned around.

Getting Started

Deploy kernel-enforced risk management for your trading systems in under an hour.

Installation

# Install Agent OS with finance module
pip install agent-os[finance]

# Or with full monitoring stack
pip install agent-os[finance,monitoring,compliance]

Quick Start

from agent_os import Kernel
from agent_os.finance import TradingKernel, RiskPolicy
from agent_os.compliance import ComplianceLogger

# 1. Initialize kernel with risk policy
kernel = TradingKernel()
kernel.load_policy("risk-policy.yaml")
kernel.load_circuit_breaker("circuit-breaker.yaml")

# 2. Configure compliance logging
compliance = ComplianceLogger("compliance-config.yaml")
kernel.set_compliance_logger(compliance)

# 3. Create your trading agent
from your_agent import TradingAgent

agent = TradingAgent(
    kernel=kernel,
    model="gpt-4",
    capabilities=[
        "market_data.read",
        "execute_trade",
        "portfolio.read"
    ]
)

# 4. Run with kernel enforcement
async def main():
    # All agent actions flow through the kernel
    # Risk limits are enforced unconditionally
    await agent.run()

if __name__ == "__main__":
    import asyncio
    asyncio.run(main())
