Map economic sectors in Windsurf

Cascade reads your requirements and identifies the correct tax bracket using `list_secoes_cnae`. It navigates the 21 primary sectors without you needing to hunt through documentation. Once the sector is identified, Cascade drills down into divisions. It uses `list_divisoes_cnae` to refine your search, ensuring your project logic stays aligned with federal standards.

Automate class lookups for compliance

Stop guessing which code applies to your data. Windsurf triggers `list_classes_cnae` to pull valid categories for any given division, providing a clean list of options for your code. This workflow prevents manual entry errors. Cascade handles the tool calls in the background, keeping your IDE environment free of clutter.

Extract precise subclass details

Get the final code you need for your backend logic. The agent calls `list_subclasses_por_classe` to see every available subclass under a specific category. When you need the exact definition of a code, Cascade executes `get_subclasse_cnae`. It returns the specific tax subclass info so your application logic stays accurate and audit-ready.
