What it does

Example prompts

• “External Fulfillment API”
• “/linkfox-amazon-store-external-fulfillment”

• A credential in LINKFOX_AGENT_API_KEY
• A credential in LINKFOXAGENT_API_KEY

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

1. 1运行 python scripts/check_auth_dependency.py；若 exit code 42 且 stderr 含 DEPENDENCY_MISSING:，请先安装 linkfox-amazon-store-auth。
2. 2不要在本 skill 内绕过依赖实现授权或令牌逻辑。
3. 3商家需 External Fulfillment allowlist，应用需 Direct-to-Consumer Shipping (Restricted) 角色。

What it can do on your machine

Read from SKILL.md and the folder at commit 38fef04. 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 16 files in scripts/ (Python), which the agent can run.

  Shell commands in SKILL.md call:

  • python

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Links to these hosts (documentation or services it may open):

  • developer-docs.amazon.com
  • skill.linkfox.com

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

• Credentials

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

  • LINKFOXAGENT_API_KEY
  • LINKFOX_AGENT_API_KEY

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

Context cost

Linkfox Amazon Store External Fulfillment loads about 2.1k tokens when it runs, and up to ~4.2k if it reads all its reference files. Until then it costs about 118 tokens; SKILL.md has 416 words of instructions outside code blocks.

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

~118

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

~2.1k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~4.2k

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); the scripts in this folder are not scanned.
