What it does
Webshop Price Checker is an agent skill from zjunlp/SkillNet. This skill scans product listings or detail pages to verify if an item's price meets a specified budget constraint. It is triggered when evaluating a potential product for purchase. It extracts the price from the displayed information (e.g., '$164.95') and compares it against the maximum allowed budget, outputting a boolean decision on whether the item is within budget.
Its SKILL.md is about 400 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/price_patterns.md`).
It sits in Sales & Support, covering E-commerce operations. The repository describes itself as: Create, Evaluate, and Connect AI Skills. The licence is MIT.
When your agent uses it
- Tasks that involve E-commerce operations
Example prompts
- “/webshop-price-checker”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Identify the Budget: Extract the maximum allowed price from the user's instruction or the current context. The budget is typically…
- Locate the Price: On the current web page (search results or product detail page), find the price string. It is usually prefixed with a $…
- Execute Check: Run the check_price.py script, providing it with the extracted price string and the budget.
- Make Decision: Based on the script's boolean output (True/False)
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 Price Checker loads about 402 tokens when it runs, and up to ~647 if it reads all its reference files. Until then it costs about 99 tokens; SKILL.md has 185 words of instructions outside code blocks.
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 scans product listings or detail pages to verify if an item's price meets a specified budget constraint. It is triggered when evaluating a potential product for purchase. It extracts the price from the displayed information (e.g., '$164.95') and compares it against the maximum allowed budget, outputting a boolean decision on whether the item is within budget.
Instructions
When evaluating a product for purchase, use this skill to check if its price is within the specified budget.
Process
- Identify the Budget: Extract the maximum allowed price from the user's instruction or the current context. The budget is typically expressed as a dollar amount (e.g., "lower than 200.00 dollars").
- Locate the Price: On the current web page (search results or product detail page), find the price string. It is usually prefixed with a
$symbol and may be labeled "Price:". - Execute Check: Run the
check_price.pyscript, providing it with the extracted price string and the budget. - Make Decision: Based on the script's boolean output (
True/False):- If
True: The item is within budget. You may proceed with further evaluation or purchase. - If
False: The item exceeds the budget. You should continue searching or select a different item.
- If
Notes
- The primary action for this skill is to call the bundled script. Do not perform manual price parsing or comparison in your main reasoning.
- If the price cannot be found on the page, assume the item is not suitable and continue your search.
