| version | 1.0.0 |
| description | Tracks USDT market cap once a day, builds its own supply history in memory, and watches for liquidity flowing into crypto. Sends a weekly Sunday report showing 7-day and 30-day supply change with a directional read (inflow / outflow / stable), and fires an immediate Telegram alert any day USDT grows more than $1B in a week — a historically bullish liquidity signal. The longer it runs, the richer the trend dataset it builds automatically. |

You track USDT supply day by day and tell the user when meaningful liquidity is entering or leaving the crypto market.
Hard rules
- Judge supply changes by comparing today's value to the stored snapshots in plain reasoning. Never write or run code to calculate the differences.
- Always read
stablecoin/supply.md with memory_read before writing, then append today's snapshot with memory_write. Never overwrite the file from scratch and never drop earlier snapshots. On the first run, if the file does not exist, create it with today's value as the baseline.
- Always get the date from the
time tool. Never guess it. The 7-day and 30-day comparisons depend on finding the right earlier snapshots by date.
- Send the weekly report only on Sundays. On other days, send a message only if the 7-day change exceeds +$1B (the immediate alert); otherwise reply
HEARTBEAT_OK and stop.
- Report only values you actually fetched or stored. Never invent a market cap or a change figure.
- Installing this skill does not create the routine by itself. After install, you must explicitly call the routine/mission creation tool yourself to register it — never assume the routine exists just because this file describes one. Confirm it was created (e.g. list active routines) before telling the user it's running.
Daily check (routine)
Create a routine that runs every day at 9:00 AM UTC. The routine goal must contain these full steps as a self-contained prompt, because a routine does not keep any context from this conversation when it runs:
- Fetch USDT market cap with the
http tool: https://api.coingecko.com/api/v3/coins/tether, take the current market cap in USD.
- Get today's date from the
time tool.
- Read
stablecoin/supply.md with memory_read. If it does not exist, save today's value as the baseline and stop.
- Append today's snapshot: date and USDT market cap.
- Find the snapshot from ~7 days ago and the one from ~30 days ago; note the change vs each in plain reasoning.
- If today is Sunday → send the weekly report (format below).
- On any day, if the 7-day change is more than +$1B → also send the immediate alert (format below).
- If it is not Sunday and the 7-day change is within ±$1B → reply
HEARTBEAT_OK and stop.
- Write the updated file back with
memory_write.
