Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00048 | $0.01343 |
| Opus 5 | $0.00024 | $0.00672 |
| Sonnet 5 | $0.00010 | $0.00269 |
| Haiku 4.5 | $0.00005 | $0.00134 |
Grade A, and why
shopping-admin-browser-automation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Shopping Admin Browser Automation Skill
This skill is based on Playwright MCP tools, providing automation capabilities for Magento Admin panel.
Core Concepts
In admin panel automation, we distinguish two types of operations:
- Skill: Meaningful combinations of multiple tool calls, encapsulated as independent Python scripts
- Basic Tools: Single function calls used for atomic operations.
I. Skills
1. Admin Login
Use Cases:
- Login to Magento Admin panel at the start of admin tasks
- Authenticate with admin credentials
Prerequisites:
- Get ref values for form fields
Usage:
# Usage:
# python admin_login.py <admin_url> <username> <password> <username_ref> <password_ref> <signin_ref>
# Example:
python admin_login.py http://localhost:7780/admin admin admin1234 e15 e20 e23
2. Create Customer
Use Cases:
- Create a new customer after clicking "Add New Customer" button
- Add customers to specific customer groups
Usage:
# Usage:
# python create_customer.py <first_name> <last_name> <email> <group> <group_ref> <fname_ref> <lname_ref> <email_ref> <save_btn_ref>
# Example:
python create_customer.py "Isabella" "Romano" "[email protected]" "Premium Europe" e92 e112 e124 e136 e61
II. Basic Tools (When to Use Single Functions)
Below are the basic tool functions and their use cases. These are atomic operations for flexible combination.
Note: 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:7780/admin')"
Navigation Tools
navigate(url: str)
Use Cases:
- Open admin panel URL
- Navigate to specific admin pages
Example:
python run_browser_ops.py -c "await browser.navigate('http://localhost:7780/admin')"
navigate_back()
Use Cases:
- Go back to previous page
- Return to list page after viewing details
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

shopping-admin-browser-automation is a skill published in the GitHub repository MassLab-SII/open-agent-skills (133 stars, last pushed 8mo ago), licensed Apache-2.0. It adds 48 tokens to every session and 1,343 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
