name	shopping-browser-automation
description	This skill provides tools and techniques for e-commerce website automation. Includes advanced search, product comparison, cart management, checkout process and other common shopping scenarios. Suitable for tasks requiring complex operations on e-commerce websites.

Shopping Browser Automation Skill

This skill is based on Playwright MCP tools, providing automation capabilities for e-commerce websites.

Core Concepts

In shopping website automation, we distinguish two types of operations:

1. Skill: Meaningful combinations of multiple tool calls, encapsulated as independent Python scripts
2. Basic Tools: Single function calls in utils.py, used for atomic operations.

I. Skills

1. Simple Search - Type and Submit

File: simple_search.py

Use Cases:

• Need to search for a product using the main search bar
• Want to type a search term and automatically press Enter to submit

Prerequisites:

• First use navigate() to navigate to the website homepage
• Get the ref value of the search input field

Usage:

# Usage:
#   python simple_search.py <search_term> <search_input_ref>
# Example:
python simple_search.py "gingerbread" e35

---

2. Advanced Search - By Product Name and Price Range

File: advanced_search_by_name.py

Use Cases:

• Already on the Advanced Search page
• Need to fill in product name and price range for search

Prerequisites:

• First use navigate() to navigate to the website homepage
• Then use click() to click the "Advanced Search" link
• Get the ref values of form fields

Typical Task Examples:

• Search for products with name containing "Ginger", price between $50.00 and $100.00
• Search for products with name containing "cookie", price between $20.00 and $40.00

Usage:

# Usage:

3. Advanced Search - By Description and Price Range

File: advanced_search_by_description.py

Use Cases:

• Already on the Advanced Search page
• Need to search keywords in product description (not product name)
• Need to filter by price range

Prerequisites:

• First use navigate() to navigate to the website homepage
• Then use click() to click the "Advanced Search" link
• Get the ref values of form fields

Typical Task Examples:

• Search for products with description containing "vitamin", price $0.00-$99.99

Usage:

# Usage:
#   python advanced_search_by_description.py <description> <price_from> <price_to> <desc_ref> <price_from_ref> <price_to_ref> <search_btn_ref>
# Example:
python advanced_search_by_description.py "vitamin" 0.00 99.99 e99 e110 e114 e118

4. Checkout - Fill Shipping Information

File: fill_shipping_info.py

Use Cases:

• Already on the checkout page (after clicking "Proceed to Checkout")
• Need to fill in complete shipping address information

Typical Task Examples:

• Fill in customer's name, address, city, state, zip code, phone, etc.

Prerequisites:

• First use click() to click the "Proceed to Checkout" button
• Use snapshot() to get all form field ref values

Usage:

II. Basic Tools (When to Use Single Functions)

Below are the basic tool functions provided in utils.py and their use cases. These are atomic operations for flexible combination.

Note: Basic tools need to be used in async context. Can be simplified using run_browser_ops.py. Code should be written without line breaks.

How to Run

# Standard format (browser persists across calls)
python run_browser_ops.py -c "await browser.navigate('http://localhost:7770')"

Navigation Tools

navigate(url: str)

Use Cases:

• Open website homepage
• Directly access specific product page URL
• Jump to specific URL

Example:

python run_browser_ops.py -c "await browser.navigate('http://localhost:7770')"

---

navigate_back()

Use Cases:

• Go back to previous page
• Return to search results page after browsing products

Example:

python run_browser_ops.py -c "await browser.navigate_back()"

---

Interaction Tools

click(ref: str, element: Optional[str] = None)

Use Cases (very broad):

• Click navigation menu (categories, subcategories)
• Click product links
• Click "Add to Compare" button
• Click "Add to Cart" button
• Click pagination links (Page 2, Page 3, etc.)
• Click price filters
• Click sort direction toggle

Example:

python run_browser_ops.py -c "await browser.click(ref='e56', element='Health & Household menu item')"

---

type_text(ref: str, text: str, element: Optional[str] = None)

Use Cases:

• Enter keywords in search box
• Fill single form field
• Modify quantity input box

Example:

# Enter in search box
python run_browser_ops.py -c "await browser.type_text(ref='e32', text='gingerbread', element='Search input')"
# Press Enter to submit
python run_browser_ops.py -c "await browser.press_key('Enter')"

---

fill_form(fields: List[Dict[str, str]])

Use Cases:

• Fill multiple form fields (e.g., advanced search form)
• Batch update form data
• Update quantity in shopping cart

Example:

# Fill advanced search form
python run_browser_ops.py -c "await browser.fill_form(fields=[{'name': 'Product Name', 'ref': 'e111', 'value': 'cookie'}, {'name': 'Price From', 'ref': 'e134', 'value': '20.00'}, {'name': 'Price To', 'ref': 'e138', 'value': '40.00'}])"

# Update cart quantity
python run_browser_ops.py -c "await browser.fill_form(fields=[{'name': 'Qty', 'ref': 'e141', 'value': '3'}])"

---

select_option(ref: str, element_desc: str, value: str)

Use Cases:

• Select sort method (Sort By: Price, Relevance, etc.)
• Select country/state/province dropdown
• Select product options (e.g., Flavor, Size, etc.)

Example:

# Sort by price
python run_browser_ops.py -c "await browser.select_option(ref='e114', element_desc='Sort By dropdown', value='Price')"

# Select product flavor
python run_browser_ops.py -c "await browser.select_option(ref='e128', element_desc='Flavor', value='Peanut Butter')"

---

press_key(key: str)

Use Cases:

• Submit search (press Enter key)
• Close dialog (press Escape key)

Example:

# Press Enter after typing in search box
python run_browser_ops.py -c "await browser.press_key('Enter')"

---

Page State Tools

snapshot()

Use Cases (very important):

• When unsure about current page state
• Need to view complete page content to decide next action
• Verify if operation was successful
• Find ref references for specific elements

Example:

python run_browser_ops.py -c "await browser.snapshot()"

Best Practices:

• Use snapshot before and after critical operations to confirm state
• Use snapshot on search results page to view all products
• Use snapshot after page navigation to confirm page loaded completely

---

get_console_messages()

Use Cases:

• Debug JavaScript errors
• View log information during page loading

---

get_network_requests()

Use Cases:

• Debug network request issues
• View API call status

---

Wait Tools

wait_for_time(seconds: int)

Use Cases:

• Wait for page to load completely
• Wait for animation effects to finish
• Wait for async data loading

Example:

python run_browser_ops.py -c "await browser.wait_for_time(3)"

---

Tab Management

list_tabs()

Use Cases:

• View all currently open tabs
• Get tab ID

---

tab_new(url: Optional[str] = None)

Use Cases:

• Open product detail page in new tab (keep search results page)
• Compare multiple products simultaneously

Example:

python run_browser_ops.py -c "await browser.tab_new(url='http://localhost:7770/product-page.html')"

III. Best Practice Recommendations

1. Make Good Use of snapshot()

Use snapshot() in the following situations:

• Just entered a new page, unsure about page structure
• After executing an operation, need to verify results
• Need to find ref references for elements
• Unsure about current sort order (descending or ascending) / filter state

---

Usage Principles

1. Prefer combined skills for fixed workflows: e.g., advanced search, add quantity to cart, fill forms
2. Use basic tools flexibly for changing scenarios: e.g., click, input, select and other atomic operations
3. Make good use of snapshot() to understand page state: confirm state before and after critical steps
