校验XML数电票

This skill appears to do what it says (validate Chinese e-invoice XML) and does not ask for credentials, but before using it consider: 1) Don't run the script on untrusted XML in a sensitive environment — xml.etree.ElementTree.parse() can be unsafe for malicious XML; prefer defusedxml or explicitly disable DTD/entity processing. 2) The script prints invoice numbers and taxpayer IDs (sensitive PII); redact or run validation in a trusted/isolated environment if you care about privacy. 3) If you will integrate this into production, add robust namespace handling, input size limits, and explicit safe XML parsing to prevent DoS or XXE. If you need, I can suggest a hardened Python implementation that mitigates XXE and large-entity attacks and that redacts or masks PII in reports.
