WHAT IT DOES

What crow_tax_new_return does on Crow

AI agents use crow_tax_new_return to create or update resources in Crow, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Crow environment.

RISK

Why crow_tax_new_return is rated Medium

This tool creates a new tax return record, which is a Write operation (creating data). While tax returns are financially significant documents, this tool creates the record/filing rather than moving money or committing a financial obligation directly. However, it is high severity because tax filings are sensitive financial/legal documents that could have serious consequences if misused or filed incorrectly.
