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 Product Evaluator loads about 692 tokens when it runs, and up to ~1.1k if it reads all its reference files. Until then it costs about 98 tokens; SKILL.md has 309 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
- Evaluates product listings against user requirements such as price limits and feature matches to identify viable options. Use when you are on a search results page containing multiple products and need to select the most promising candidate for detailed inspection. The skill analyzes product titles, prices, and brief descriptions to rank and choose the best match.
Instructions
When to Use
Activate this skill when you are on a search results page in a web shopping environment and need to evaluate multiple products against specific user requirements (e.g., price limits, feature keywords).
Core Process
- Parse the Observation: Identify the user's instruction, the list of available products, and their associated details (Title, Price, ASIN/Product ID).
- Extract Requirements: From the user instruction, identify:
- Price Limit: The maximum acceptable price (e.g., "lower than 40.00 dollars").
- Feature Keywords: Key product attributes (e.g., "teeth whitening", "freshens breath").
- Evaluate Products: For each product listing on the current page:
- Check if the price is below the user's limit.
- Check if the product title contains the required feature keywords.
- Prioritize products that meet all criteria. If multiple products qualify, choose the one that appears most relevant or cost-effective.
- Take Action:
- If a suitable product is found, click on its product ID (e.g.,
click[B09NYFDNVX]) to view its details. - If no suitable product is found on the current page, consider using the
searchaction with refined keywords or clickingNext >to browse more results.
- If a suitable product is found, click on its product ID (e.g.,
Thought Process Format
Always structure your internal reasoning and final action using this format:
Thought: [Summarize the user's constraints, evaluate each product against them, and justify your selection.]
Action: click[<product_id>]
Example
Instruction: "i need a teeth whitening toothpaste that also freshens breath, and price lower than 15.00 dollars"
Observation (Search Results Page):
- B09NYFDNVX: "Whitening Toothpaste with Breath Freshener" — $12.99
- B08KZPTL3M: "Professional Teeth Whitening Kit" — $24.99
- B07HQRJ4WP: "Mint Fresh Whitening Toothpaste" — $9.49
Thought: The user needs a teeth whitening toothpaste that freshens breath, under $15. Product B09NYFDNVX at $12.99 mentions both "whitening" and "breath freshener" in the title — meets all criteria. B08KZPTL3M exceeds the budget at $24.99. B07HQRJ4WP is within budget and mentions "whitening" but does not explicitly mention breath freshening. Selecting B09NYFDNVX as the best match.
Action: click[B09NYFDNVX]
