description	Price and volume tracker for [REPLACE: TOKEN_SYMBOL] with anomaly alerts above [REPLACE: ALERT_THRESHOLD_PCT]% movement

${var} — Optional. Pass a different CoinGecko ID to override the default. If empty, tracks the configured token.

Today is ${today}. Track [REPLACE: TOKEN_SYMBOL] price/volume and alert on anomalies.

Steps

1. Fetch current state — query CoinGecko for the latest price, 24h change, 24h volume. Use COINGECKO_API_KEY if set, else the keyless endpoint:

   ID="${var:-[REPLACE: COINGECKO_ID]}"
   if [ -n "${COINGECKO_API_KEY:-}" ]; then
     URL="https://pro-api.coingecko.com/api/v3/simple/price?ids=$ID&vs_currencies=usd&include_24hr_change=true&include_24hr_vol=true"
     curl -sf -H "x-cg-pro-api-key: $COINGECKO_API_KEY" "$URL" > .token-cache.json
   else
     URL="https://api.coingecko.com/api/v3/simple/price?ids=$ID&vs_currencies=usd&include_24hr_change=true&include_24hr_vol=true"
     curl -sf "$URL" > .token-cache.json
   fi
   

   If a curl GET is flaky, use WebFetch on the same URL as a fallback (there is no network sandbox — WebFetch is just a convenience for flaky public reads).

2. Read prior state — last 7 days of memory/logs/YYYY-MM-DD.md for previous prices and volumes (parse lines like **[REPLACE: TOKEN_SYMBOL]**: price=$N, volume_24h=$N).

3. Detect anomalies — flag if |price_change_24h| >= [REPLACE: ALERT_THRESHOLD_PCT]% OR if 24h volume is >= 2x the 7-day median.

4. Write output/articles/[REPLACE: SKILL_NAME]-${today}.md with:

   • Current price, 24h change, 24h volume
   • 7-day price chart (sparkline as ▁▂▃▅▇ characters)
   • Anomaly verdict: QUIET / STEADY / ANOMALY (and which fired)
   • Links: CoinGecko page, Etherscan / explorer page if you know the contract address

5. Notify — if ANOMALY, send via ./notify with the verdict + 1-2 sentences of context. Stay silent on QUIET/STEADY days.

6. Log — append to memory/logs/${today}.md:

   ## [REPLACE: SKILL_NAME]
   - **[REPLACE: TOKEN_SYMBOL]**: price=$N, change_24h=$N%, volume_24h=$N
   - **Verdict**: QUIET | STEADY | ANOMALY:price | ANOMALY:volume
   

Network note

CoinGecko's keyless endpoint occasionally rate-limits. There is no network sandbox — curl works; use WebFetch as the fallback when a curl GET is flaky.

Constraints

• Never spam. The ALERT_THRESHOLD_PCT gate is there to protect channel signal — don't lower it below 5%.
• Always cite sources in the article. Even a one-line link is better than no link.
