vb-migration-harness

Use when refactoring ADO.NET DataSet/DataTable/DataRow code into typed C# DTOs and safe parameterized queries using Dapper (or parameterized SqlCommand). Focuses on minimal risk and incremental cutover, one query at a time.

Use this skill specifically for the custom expression evaluation / data transformation module in the VB codebase. This module acts as a business-rules engine and requires extreme care: golden-master tests MUST be in place before any extraction begins. Do not use the generic extractor skill for this module.

Use when wrapping the legacy SOAP web service behind an ILegacyApi interface boundary. Enables testing and future replacement. Produces the interface, real adapter, test fake, and contract tests. SOAP is an external fixed contract — we adapt to it, not change it.

Use this skill to capture the current behavior of an ASP.NET WebForms workflow before any refactoring begins. Produces Playwright E2E tests and/or golden-master approval tests that act as the migration oracle. Invoke before extracting business logic from any VB event handler.
