WHAT IT DOES

What search_modules_files does on Slack

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

RISK

Why search_modules_files is rated Low

This tool retrieves file data from Slack via a search operation. While categorized as Read (no side effects), severity is elevated to medium because: (1) it searches across files that may contain sensitive organizational data, customer information, or intellectual property; (2) the description notes it uses an 'undocumented session endpoint,' suggesting potential for unintended scope creep or access control bypass;…

From the tool's definition Tool name contains 'search' and description states 'Search files'; the action is retrieval/querying without modification or deletion.
