Demo — Autonomous Trading Agent

A fully autonomous Drift perpetuals trading agent that runs without human input.

demo/src/agent.ts is a complete autonomous Drift trading agent. It reads GLOSSO.md at startup, discovers its tools, and executes a full trading cycle — price check, deposit, open position, monitor PnL, close — without any human prompting.

---

What the Agent Does

1. Fetches live SOL price from Pyth Network
2. Decides direction — long or short — based on a configurable signal
3. Deposits collateral into Drift protocol
4. Opens a SOL-PERP position with the deposited collateral
5. Monitors PnL in real time
6. Closes the position when the target is reached
7. Logs every step to ~/.glosso/activity.log

The agent loop runs until the task is complete or maxRounds is hit. Every tool call and LLM reasoning step is visible in glosso monitor.

Run It

1. Provision a wallet (if you haven't)

   npx tsx packages/cli/src/index.ts provision --mode sovereign
   
2. Set up the demo environment

   cd demo
   cp .env.example .env
   

   Edit .env and add your LLM API key:

   XAI_API_KEY=your_key_here      # for Grok
   # or
   OPENAI_API_KEY=your_key_here   # for GPT-4o
   
3. Install demo dependencies

   pnpm install
   
4. Run the agent

   npx tsx src/agent.ts
   
5. Watch it live (optional, in a second terminal)

   npx tsx packages/cli/src/index.ts monitor

How It Works

The demo agent uses the ai SDK with a tool-use loop:

// Simplified demo/src/agent.ts
const systemPrompt = glossoMd + driftCapabilities;

while (round < maxRounds) {
  const response = await generateText({
    model: xai('grok-2-1212'),
    system: systemPrompt,
    messages: history,
    tools: { glosso_balance, glosso_price, deposit_collateral, open_perp_position, ... },
  });

  if (response.finishReason === 'stop') break;

  // Execute tool calls, add results to history
  history.push(...toolResults);
  round++;
}

GLOSSO.md in the system prompt tells the agent exactly which tools exist and how to call them. The agent reasons about its current state (balance, price, position) and decides what to do next.

Adding Policy

Before running the demo against a real account, you should set spend limits:

npx tsx packages/cli/src/index.ts policy set MAX_SOL_PER_TX 1.0
npx tsx packages/cli/src/index.ts policy set MAX_SOL_PER_DAY 5.0
npx tsx packages/cli/src/index.ts policy allow-program dRiftyHA39MWEi3m9aunc5MzRF1JYuBsbn6VPcn33UH
npx tsx packages/cli/src/index.ts policy allow-program 11111111111111111111111111111111

Then in the demo, wrap the wallet:

const wallet = new GlossoWallet();
const scoped = wallet.withPolicy({}); // reads ~/.glosso/policy.json automatically

Demo Tools

Tool	What It Does
glosso_balance	Check SOL balance
glosso_price	Fetch SOL price from Pyth
deposit_collateral	Deposit SOL into Drift
open_perp_position	Open SOL-PERP long or short
get_position	Check current position and unrealized PnL
close_perp_position	Close the open position
withdraw_collateral	Withdraw remaining collateral

The demo is configured for devnet by default. Do not run it on mainnet without updating GLOSSO_NETWORK=mainnet-beta in .env and setting appropriate policy limits.
