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 (3)

cert_guideWhich mill cert type applies for a grade + use case (e.g. EH36 shipbuilding), and what fields to check on the cert.
grade_lookupLook up a steel grade: properties, chemistry, forms, applications, weldability. Aliases accepted (e.g. 4140 = 42CrMo4 = SCM440).
substitution_checkCheck if one steel grade can substitute another for a given application (machined / welded-structural / pressure). Returns verdict + reasoning from verified trade rules.

Schemas: list_tools.
