Weekly Bitcoin buying agent

Every Monday at 09:00 UTC, add $20 of position value to a 1x BTC long on Hyperliquid, keeping position value at or below my allocation instead of changing account leverage, at most once per week. Never reduce the position. Skip the week if my allocation available as margin is below the amount, without making up missed buys later. Stop adding and tell me if the position's margin ratio drops into liquidation risk. Make the amount, day and time adjustable.

Start from this exact spec: "Build an agent that adds to a BTC long every week". Builder turns it into an agent and checks the code. Backtest it on recorded markets and paper trade it on live markets before real money moves. Every number in the spec is a setting.

Agents run on a wallet you create in Circuit or import by private key. Circuit keeps the signing key in a hardware enclave. Agents never see it. An agent requests typed actions through Circuit's SDK. Nothing is signed without the permit you sign with your passkey when you start the agent.

You can export the private key from Settings at any time. You can pause, resume or stop an agent at any time. Stopping leaves your positions and resting orders in your account. You ask Circuit to close them.
