Search SEC EDGAR for company filings (10-K, 10-Q, 8-K, etc.). Accepts ticker symbol or CIK number.
AI agents call company_filings to retrieve information from Publicfinance without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
SEC EDGAR filings are public records. The tool accepts inputs (ticker/CIK) to query and return documents—a classic read operation with no side effects, no code execution, no data modification, and no financial transactions. The blast radius of misuse is minimal; an agent cannot harm systems or data by searching for public filings. Low severity is appropriate for unauthenticated public data retrieval.
From the tool's definition Tool 'Search SEC EDGAR for company filings' retrieves publicly available regulatory documents. Key verbs are 'search' and 'accepts' (query parameters), with no mention of modification, deletion, or execution. The description indicates data retrieval only.
