What problem does it solve? Writing K/3 Cloud (Kingdee Cloud Cosmic) Python plugins requires knowing which of the four plugin types to use, which event to override, and how IronPython 2.7 differs from modern Python. This Skill acts as an index that routes the agent to the right reference file before generating plugin code for registration tools like k3cloud_register_python_plugins. ## Core Features & Use Cases - Four plugin type coverage: Form plugins (AbstractBillPlugIn), list plugins (AbstractListPlugIn), operation service plugins, and SysReport plugins, each with minimal working templates and registration tool mapping. - On-demand reference loading: Events signature reference (130+ virtual methods with customer-validated frequency data), Model/View/Context API guide, and 9 reusable code templates loaded selectively via load_skill_file. - Debugging and error-handling playbooks: Step-by-step troubleshooting for plugins that don't trigger, plus the e.Cancel + KDException pattern for blocking saves with localized Chinese error messages. - Use Case: A consultant needs to block saving a sales order when the amount exceeds the customer's credit limit. The Skill routes to the BeforeSave template, the cross-table credit lookup pattern, and the correct exception-raising idiom, producing a ready-to-register pyBody. ## Quick Start Load this skill before generating any K/3 Cloud Python plugin code, then pull only the specific reference file matching your event, API, or template need.
