Automated Compliance Checks for Windsurf

When you set a goal in Windsurf, Cascade figures out the necessary steps. It uses the `validate_vat` tool to check if tax numbers are formatted correctly against strict country algorithms. This means your autonomous agent doesn't fail just because of a bad ID format. It validates European and international VAT numbers right when it needs them.

Cross-Border Data Validation

The `validate_vat` tool performs offline mathematical validation on tax number strings. You feed it the number, and Cascade runs a check against the correct country standard. It handles both European VAT numbers and global Tax IDs, making sure your multi-step process only proceeds with verified data.

Contextual Tax ID Verification

Cascade reads context to know when validation is needed. You don't have to manually prompt for every check; the agent just calls `validate_vat` when it sees a tax number. This ensures B2B compliance happens naturally as part of your complex, multi-tool workflow.
