Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (2)

`lookup_hts`read-only	Use this when the user gives an HTS / HS tariff code (4, 6, 8 or 10 digits, e.g. 8516.60.40 or 9503000071) and wants the US duty rate, Section 301 China tariff status, units or the official description.
`search_hts`read-only	Use this when the user describes a product and wants its US HTS code, tariff classification or import duty ("HTS code for…", "tariff on … from China", "import duty for …"). Searches the official US Harmonized Tariff Schedule by keywords and returns the best matching codes with rates and Section 301 China status. Then use lookup_hts for full detail on one code.
