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 (7)

`explain_standard`read-only	What a standard (AS9100D, NADCAP, ECSS, ISO 9001, MIL-STD …) certifies, why a buyer cares, what it is typically required for, and which suppliers in the index claim it.
`get_part`read-only	All specifications for one part, whether the manufacturer confirmed them, and the supplier.
`get_supplier`read-only	Full profile: what they make, capabilities (process, tolerance, envelope, material, lead time), certifications claimed, categories and products. Contact details are not returned — use the profile URL.
`list_categories`read-only	The part tree (segment → assembly → component) with supplier counts. Use to see what the index covers and where it has gaps.
`request_quote`	Send a quote request to whobuildsit, which reviews it and passes it to suppliers who can make the part. Before calling, ASK THE USER for their work email and explicit consent to share the request and email with suppliers — never invent an email. Give a part_id or supplier_slug from earlier results when you have one. Suppliers reply to the user directly; nothing is sent automatically.
`search_parts`read-only	Find parts by keyword and/or numeric specification. Units are understood: "3000 psi" also matches parts rated in bar; "Ø40 mm", "1250 °C", "10 GHz" work. Returns matching parts with supplier, key specs and a URL.
`search_suppliers`read-only	Find companies that can make something — by process (e.g. "5-axis machining", "vacuum brazing"), material, certification (e.g. "AS9100D"), category, or country. Most space hardware is made to drawing by contract manufacturers that have no product catalogue; this is how to find them.

Schemas: list_tools.
