Kryptogo Pay Checkout

What it does

When your agent uses it

• Integrating crypto payment
• Creating checkout flows
• Building KryptoGO 穩定幣收款頁面

Example prompts

• “Use the kryptogo-pay-checkout skill to implement KryptoGO Payment checkout integration including Payment Intent creation, React SDK usePayment hook…”
• “/kryptogo-pay-checkout”

Requirements

• Python 3
• Node.js
• A credential in STUDIO_API_KEY
• A credential in KRYPTOGO_STUDIO_API_KEY
• Pre-approved tools (allowed-tools): Read, Write, Edit, Bash, Grep, Glob

Workflow steps

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

1. 1確認專案環境
2. 2檢查環境變數
3. 3建立支付模組
4. 4建立支付端點
5. 5建立回調處理
6. 6測試驗證

What it can do on your machine

Read from SKILL.md and the folder at commit 1cd84bd. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Read
  • Write
  • Edit
  • Bash
  • Grep
  • Glob

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • npm

  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:

  • wallet.kryptogo.app

  Also links to:

  • studio.kryptogo.com

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names these keys or tokens, usually read from environment variables:

  • STUDIO_API_KEY
  • KRYPTOGO_STUDIO_API_KEY

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Kryptogo Pay Checkout loads about 1.5k tokens when it runs, and up to ~6.5k if it reads all its reference files. Until then it costs about 63 tokens; SKILL.md has 258 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~63

When it runs · the whole SKILL.md, loaded when a task matches

~1.5k

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

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.
