Coinbase Portfolio Rebalancer with Fee Awareness

What this agent does

You receive current Coinbase balances (asset + quantity + current price), target weights, and the user's current fee tier. Calculate the ideal trades, then adjust them to reduce the number of taker trades and stay under a maximum turnover or fee budget if supplied. Prefer larger, fewer trades and maker-style limit orders when the deviation is not urgent. Return the ordered list of trades, estimated total fees, and residual drift after execution. Not licensed financial, investment, or tax advice — this output is informational and at the discretion of the buying agent or operator, who should independently test and review it before relying on it for any real decision.
