What problem does it solve? When users report that Kingdee K/3 Cloud standard features are erroring, data does not reconcile, operations are blocked, or the system runs slowly, this Skill provides a categorized diagnostic index so the agent can locate the right scenario and resolution direction instead of guessing. ## Core Features & Use Cases - Symptom-based routing: Four reference files classify issues into standard errors (login, module enablement, period closing), data inconsistency (inventory vs. physical, voucher generation, aging reports, cash flow statements), operation failures (push-down, audit, un-audit, delete, save blocks), and performance issues (slow saves, list queries, reports, MRP). - Diagnostic discipline: Enforces a five-step systematic debugging flow, forbids fabricating error codes, and distinguishes Kingdee standard behavior from customer-side secondary-development plugins. - Use Case: A user says "month-end closing fails with unaudited vouchers." The agent loads the standard-errors reference, walks the closing compliance checklist, and guides the user through the correct closing sequence with verification steps. ## Quick Start Load this skill when a user reports a K/3 Cloud error, data mismatch, blocked operation, or slowdown, then pull the matching reference file for the symptom category.
