MISTAKES — Read Before Calling
❌ MISTAKE 1: Using TwelveData for crypto
User: "BTC 价格"
❌ WRONG: twelvedata_quote(symbol="BTC/USD")
✅ RIGHT: coin_price(ids="bitcoin") ← CoinGecko❌ MISTAKE 2: Calling quote individually for multiple stocks
User: "AAPL MSFT GOOGL 现在什么价"
❌ WRONG: twelvedata_quote("AAPL"), twelvedata_quote("MSFT"), twelvedata_quote("GOOGL") ← 3 calls
✅ RIGHT: twelvedata_quote_batch(symbols=["AAPL", "MSFT", "GOOGL"]) ← 1 call, up to 120 symbols❌ MISTAKE 3: Forex without slash
❌ WRONG: twelvedata_quote(symbol="EURUSD")
✅ RIGHT: twelvedata_quote(symbol="EUR/USD") ← always slash formatAlso: USD/CNH not USDCNH, GBP/JPY not GBPJPY.
❌ MISTAKE 4: Expecting bid/ask from quote
❌ WRONG: "EUR/USD bid: 1.0850, ask: 1.0852" ← quote only returns close
✅ RIGHT: "EUR/USD current price: 1.0851 (close/last price — bid/ask spread not available)"❌ MISTAKE 5: Wrong interval format
❌ WRONG: twelvedata_time_series(interval="1D") ← uppercase
✅ RIGHT: twelvedata_time_series(interval="1day")Valid: 1min, 5min, 15min, 30min, 1h, 2h, 4h, 8h, 1day, 1week, 1month
❌ MISTAKE 6: Using full output when compact suffices
User: "AAPL 最近走势"
❌ WRONG: twelvedata_time_series(symbol="AAPL", interval="1day", outputsize="full") ← 5000 candles
✅ RIGHT: twelvedata_time_series(symbol="AAPL", interval="1day", outputsize="compact") ← 30 candlesUse full only when user explicitly needs deep history.
