name: webshop-variant-chooser description: This skill selects a product variant (e.g., size, quantity) from available options on a product detail page. It is triggered when a product page displays multiple choices, assessing the options (like '1.1 pound (pack of 1)' or 'pack of 2') and selecting one that aligns with user needs, often defaulting to a standard single unit if unspecified.

Instructions

When to Use

Use this skill when you are on a product detail page and the observation contains a list of variant options (e.g., under a "size" or "quantity" heading). The skill is triggered by the presence of multiple clickable options that represent different configurations of the same product.

Core Decision Logic

1. Parse the Observation: Identify the list of available variant options from the observation text. These are typically presented as clickable values after a label like "size".
2. Assess User Needs: Review the original user instruction for any explicit or implicit preferences regarding variant (e.g., budget constraints, desired quantity). If no preference is stated, default logic applies.
3. Select and Act: Choose the most appropriate variant and execute a click[value] action.
   • If user instruction specifies a constraint (e.g., "price lower than 40.00 dollars"): Ensure the selected variant's price (if displayed) complies.
   • If no user preference is stated: Prefer the standard, single-unit option (e.g., "1.1 pound (pack of 1)" over "pack of 2") as a sensible default.
   • If the choice is ambiguous: You may need to click on a variant to see its updated price/details before finalizing the selection, as shown in the trajectory.
