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.

explain_ruleread-only Explain an EN 16931 / XRechnung / Peppol business rule by id (e.g. BR-CO-10, BR-DE-15, PEPPOL-EN16931-R001): what it means and how to fix it.

validate_einvoiceread-only Validate an XRechnung / Peppol BIS 3 / EN 16931 e-invoice (UBL 2.1 Invoice/CreditNote or CII CrossIndustryInvoice XML) with the official KoSIT validator. Returns accepted/rejected, the matched scenario and every error and warning with rule id, message, location and a link to a plain-language explanation. For rejected files it also reports which errors an automatic repair removes (measured on this file).

Schemas: list_tools.
