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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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.

How to install
mdr add zjunlp/skillnet/webshop-variant-chooser@sha256:4120f64ddfedc237The line at the top of this page pins the label git:20260307.388baa3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
