Read a tax document PDF (W-2, 1099, 1098-T) and extract data. Returns extracted values with confidence scores. Low-confidence fields MUST be confirmed with the user before adding to the return.
AI agents call crow_tax_ingest_document to retrieve information from Crow without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries structured data from documents with no side effects—a classic Read operation. Severity is medium (not low) because tax documents contain personally identifiable and sensitive financial information (W-2, 1099, 1098-T forms); exposure or misuse by an unaligned agent could enable identity theft, fraud, or tax manipulation, though the tool itself does not write, delete, or execute…
From the tool's definition Tool description states 'Read a tax document PDF' and 'extract data'; no modification, deletion, or execution of external operations. Returns extracted values for user review.
