What it does

Webshop Variant Chooser is an agent skill from zjunlp/SkillNet. 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.

Its SKILL.md is about 450 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/trajectory.md`).

It sits in Education, covering Quizzes and assessments. The repository describes itself as: Create, Evaluate, and Connect AI Skills. The licence is MIT.

When your agent uses it

  • Tasks that involve Quizzes and assessments

Example prompts

  • “1.1 pound (pack of 1)”
  • “pack of 2”
  • “/webshop-variant-chooser”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Parse the Observation: Identify the list of available variant options from the observation text. These are typically presented as…
  2. Assess User Needs: Review the original user instruction for any explicit or implicit preferences regarding variant (e.g., budget…
  3. Select and Act: Choose the most appropriate variant and execute a click[value] action.

What it can do on your machine

Read from SKILL.md and the folder at commit c527136. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Webshop Variant Chooser loads about 447 tokens when it runs, and up to ~514 if it reads all its reference files. Until then it costs about 92 tokens; SKILL.md has 205 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~92
When it runs · the whole SKILL.md, loaded when a task matches
~447
With references · SKILL.md plus every file in references/, read only if the agent opens them
~514

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.
