btc-dominance-alert

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: 1. 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 %. 2. Read `btc-dominance/last-check.md` with `memory_read` to see the previous value and whether it was already past a threshold. 3. Compare the current value to the thresholds: - below 60% → altcoin-season signal - above 65% → BTC dominance expanding - 60–65% → no alert 4. Send an alert (format below) only if the value has crossed a threshold that it wasn't already past last run. 5. Append this check to memory: timestamp, current value, alert sent yes/no. 6. If no new crossing, reply `HEARTBEAT_OK` and stop. Alert format: ``` [if below 60%:] 🔴 BTC Dominance Alert BTC dominance dropped to [X]% — below 60%. Possible altcoin-season signal. [if above 65%:] 🟡 BTC Dominance Alert BTC dominance rose to [X]% — above 65%. BTC dominance expanding. 🕐 [timestamp] ``` ## Commands - `show btc dominance` — fetch the current dominance now and show it with the last logged value
