What crow_tax_calculate does on Crow
AI agents invoke crow_tax_calculate to trigger actions in Crow. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why crow_tax_calculate is rated High
This tool executes a tax calculation engine, producing artifacts (audit trails, summaries) that have financial and compliance implications. While not directly moving money (Financial category) or destructively deleting data (Destructive), it executes complex logic whose outputs could influence financial decisions and tax reporting. The audit trail generation suggests state changes in a persistent system.
From the tool's definition The tool description states 'Run the full tax calculation' which indicates it executes a computational process with side effects (generating calculation results and audit trails).
