What it does

Use when the user wants to buy/purchase/pay/transfer/send (买, 购买, 支付, 付款, 转账, 发送), confirm/cancel payment (确认, 取消), or query order status (查询, 订单). Requires QR code data from user.

Its SKILL.md is about 6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including reference files (for example `extension/__init__.py`, `extension/base.py` and `extension/c2c_extension.py`).

It works with Python.

Workflow steps

8 steps, taken from the step headings in SKILL.md.

Try to READ the QR data directly (Vision)
Check for image file path
Ask user for help (DO NOT auto-use clipboard!)
Only after user confirms → use clipboard
Get QR Data (Choose ONE method)
Purchase (IMMEDIATELY after getting QR data)
Set amount (if needed)
Confirm payment (after user confirms)

What it can do on your machine

Read from SKILL.md and the folder at commit db435ed. 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
Ships script files (Python), which the agent can run.
Shell commands in SKILL.md call:
- python3
- pip
- python
- brew
- apt
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- bpay.binanceapi.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- PAYMENT_API_KEY
- PAYMENT_API_SECRET
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Payment Assistant loads about 6k tokens when it runs, and up to ~6.5k if it reads all its reference files. Until then it costs about 87 tokens; SKILL.md has 2,162 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~87
When it runs · the whole SKILL.md, loaded when a task matches: ~6k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~6.5k

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.
