Codex to reorder supplements for review

Tilman Resch demonstrated a personal purchase inside Codex rather than moving between a separate chat and store browser. The task was to reorder supplements from a website he already used and put the required products in its shopping basket.

FROM THE SOURCE

Original prompt

Shared by the source author. See source notes for context.

Please go on the website and put that into the shopping cart.

What happened

The recorded account shows a prepared supplement basket and human-completed order; voucher savings are reported without a reliably readable currency amount.

Reported by Tilman Resch

How the agent did it

  1. Give Codex the familiar store and the products to reorder.
  2. Let the browser agent prepare the basket and test available voucher codes.
  3. Handle login and manually complete the payment and order.

Where a person stepped in

Resch handled account login and manually finished payment and the order.

Tilman Resch demonstrated a personal purchase inside Codex rather than moving between a separate chat and store browser. The task was to reorder supplements from a website he already used and put the required products in its shopping basket.

The recorded workflow shows Codex working through the store and preparing the basket. Persistent personal context supplied information such as his work address, so he did not have to restate every delivery detail in the shopping request. The agent also looked for voucher codes while carrying out the order preparation.

Resch retained the account and payment handoffs. He logged in when needed and manually completed the payment and order action. The useful result was a populated basket and a purchase he could finish, with the browser work attached to the same agent session. This account does not establish an autonomous payment or a new medical recommendation.

The transcript reports a voucher saving, but the displayed currency text is corrupted. No exact saving amount is repeated here. Product names are also not needed to copy the workflow: this was a repeat purchase with existing preferences, not a comparison of supplement effectiveness. The published instruction below is a short verbatim excerpt from the demonstration. It illustrates the basket task without claiming to contain the entire session's personal context.
