# Stablecoin Supply Tracker — Weekly liquidity inflow monitor with Telegram alerts

## Example Prompt

> You are my stablecoin supply tracker. Monitor USDT market cap and alert me when significant liquidity enters the crypto market.
> 
> Create a routine that runs every day at 9:00 AM UTC:
> 
> 1. Fetch USDT market cap from CoinGecko:
> https://api.coingecko.com/api/v3/coins/tether
> 
> Extract: current market cap in USD
> 
> 2. Read memory at stablecoin/supply.md using memory_read.
> If file does not exist, create it with today's snapshot as the baseline.
> 
> 3. Append today's snapshot to memory:
> - Date
> - USDT market cap
> - Change vs 7 days ago
> 
> 4. Calculate 7-day change:
> - Find the entry from 7 days ago in memory
> - Calculate difference in USD
> 
> 5. Every Sunday at 9:00 AM send a weekly report regardless of threshold:
> 
> "💵 Stablecoin Supply — Weekly Report
> 
> USDT Market Cap: $[X]B
> 7-Day Change: [+/-]$[X]B
> 30-Day Change: [+/-]$[X]B
> 
> [📈 Liquidity INFLOW — bullish signal if +$500M+ weekly]
> [📉 Liquidity OUTFLOW — bearish signal if -$500M+ weekly]
> [➡️ Stable — no significant movement]"
> 
> 6. On any day — if 7-day change exceeds +$1B: also send immediate alert:
> 
> "🚨 Stablecoin Supply Alert
> USDT grew +$[X]B in 7 days — major liquidity inflow detected.
> Historically bullish signal for crypto markets."

## What the Agent Does

Every day the agent fetches USDT market cap from CoinGecko and logs it to persistent memory. It builds its own 30-day price history over time.

Every Sunday it sends a weekly report showing 7-day and 30-day supply changes with a directional signal — inflow, outflow, or stable. If supply grows more than $1B in a week at any point, it fires an immediate alert. The longer the agent runs, the more context it builds — after a month you have a real liquidity trend dataset built automatically.
