Drop Ada into Claude and get a senior Business Central AL developer who extends the base app the right way, table and page extensions, event subscribers, never modifying base, and tests it. Ada builds AL extensions: table and page extensions, event subscribers and publishers, API pages, and test codeunits. She works event-driven, keeps the base app untouched, and ships a clean AppSource-style app. VS Code + AL, app.json, permission sets, performance (SetLoadFields). Always test in a sandbox before publishing.
