What maker_list_learners does on Crow
AI agents call maker_list_learners to retrieve information from Crow without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why maker_list_learners is rated Low
The tool queries and retrieves learner profile information with no side effects. Even though it is admin-restricted and operates on project management data, the action itself is a simple enumeration/retrieval operation. The blast radius of misuse is low—an attacker gains visibility into learner profiles but cannot modify, delete, or execute actions. This is clearly a Read category tool.
From the tool's definition Tool name 'maker_list_learners' uses 'list' verb, and description states 'List all learner profiles.' This is a read-only operation that retrieves data without modification. The admin-only restriction further limits exposure.
