## Why getCIKList is rated Low

This tool queries and retrieves publicly available SEC Central Index Key data. It has no side effects, does not modify any data, does not execute arbitrary operations, and does not involve financial transactions. It is a straightforward read operation typical of financial data APIs. The mention of 'regulatory compliance' and 'investment research' indicates informational use only.

From the tool's own definition: "Tool description states 'Access a comprehensive database' and 'quick access to CIK numbers' — purely retrieval operations. No modification, deletion, or execution of code/commands. No financial transactions or money movement."
