| name | btc-dominance-alert |
| version | 1.0.0 |
| description | Watches Bitcoin dominance (BTC's share of total crypto market cap) and alerts the user on Telegram only when it crosses a key threshold: below 60% reads as a possible altcoin-season signal, above 65% as BTC dominance expanding. Between 60% and 65% it stays silent. Each check is logged to memory as an audit trail, and it only alerts on an actual threshold crossing, never on every run. |

You watch Bitcoin dominance and alert the user only when it crosses a key threshold.
Hard rules
- Judge the threshold crossing by reading the fetched dominance value against the cutoffs in plain language. Never write or run code to do it.
- Use the thresholds exactly: below 60% = altcoin-season signal; above 65% = BTC dominance expanding; between 60% and 65% = silent. Do not invent your own cutoffs.
- Always read
btc-dominance/last-check.md with memory_read before writing, then write the full updated file back with memory_write. Never overwrite from scratch. Log every check (timestamp, value, whether an alert was sent) regardless of outcome.
- Don't repeat the same alert every run. Only alert when the value has actually crossed a threshold since the last check — if it was already below 60% last run and still is, stay silent.
- In the routine, if the value is in the 60–65% corridor or no new crossing happened, reply
HEARTBEAT_OK and stop — send no message.
- Report only the value you actually fetched. Never invent a dominance 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.
Dominance check (routine)
Create a routine that runs every 5 hours. 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 global market data with the
http tool: https://api.coingecko.com/api/v3/global. Take data.market_cap_percentage.btc — that's the current BTC dominance %.
- Read
btc-dominance/last-check.md with memory_read to see the previous value and whether it was already past a threshold.
- Compare the current value to the thresholds:
- below 60% → altcoin-season signal
- above 65% → BTC dominance expanding
- 60–65% → no alert
- Send an alert (format below) only if the value has crossed a threshold that it wasn't already past last run.
- Append this check to memory: timestamp, current value, alert sent yes/no.
- If no new crossing, reply
HEARTBEAT_OK and stop.
Alert format:

[if above 65%:]
🟡 BTC Dominance Alert
