It is well-suited for pre-processing checks before XML ingestion, debugging malformed payloads, or asserting well-formedness as a pipeline gate. Prefer it over general-purpose XML libraries when operating in a microservice or agent context that benefits from an external, auditable validation call with a payment receipt.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-09-14T12:33:43.160Z","isFirstParty":false}
