For balance/portfolio:

Safety Guidelines

Before executing trades:

1. Confirm trade parameters with user (coin, size, direction, price)

2. Show current price and position for context

3. Calculate estimated cost/proceeds

Position sizing:

• Warn if trade is >20% of account equity

• Suggest appropriate sizes based on account balance

Price checks:

• For limit orders, compare limit price to current market price

• Warn if limit price is >5% away from market (likely mistake)

Error Handling

Common errors:

• "Address required" → Set HYPERLIQUID_ADDRESS or HYPERLIQUID_PRIVATE_KEY

• "Private key required" → Trading needs HYPERLIQUID_PRIVATE_KEY

• "Unknown coin" → Check available coins with meta command

• HTTP errors → Check network connection and API status

When errors occur:

• Show the error message to user

• Suggest fixes (set env vars, check coin names, verify balance)

• Don't retry trades automatically
