## Why search_atm_offerings is rated Low

This tool retrieves and filters publicly available SEC EDGAR filing data. It has no side effects—it queries a parsed dataset and returns results. The ability to search ATM offerings by sales agent or shelf size does not create, modify, or delete any data. Financial information is presented but no financial transactions are executed.

From the tool's own definition: "Tool performs 'search' operations on parsed SEC filing data with filter and limit parameters. Returns JSON list of filing information. No action verbs indicating modification (create, update, delete) or execution (run, execute, trigger)."

## Use case

AI agents call search_atm_offerings to retrieve information from FilingFirehose without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

  "version": "1",
