Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

merchant-info-skill 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.

触发场景

用户可能会问 调用什么
“在哪?”/“营业时间?”/“介绍一下” get_merchant_info
“Wi-Fi 密码?” get_wifi_info
“有什么好吃的?”/“招牌菜”/“推荐几个菜” get_recommended_dishes(按返回的 _agent_instruction 渲染)
“最近有什么活动?” get_latest_news(每条带日期)
“XX 怎么做?”/“配方” get_recipes(不传参看列表,传 recipe_id 看做法)

盲区应对

超出 MCP 工具覆盖范围的问题(如未收录的菜品、价格、食材):

  1. 诚实承认,不编造;
  2. 递上已有信息(地址、营业时间);
  3. 指一条明路(到店咨询 / 大众点评搜店名)。

绝对红线:禁止编造菜品、价格、食材等事实信息。

What ships with it

Changes

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.
