AI agents call list_command_aliases to retrieve information from Todos without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and returns stored alias data without side effects. It is a straightforward data retrieval operation with no capability to modify state, execute commands, or cause damage. Low severity because the blast radius is minimal—leaked alias data poses no financial or operational risk.
From the tool's definition Tool name 'list_command_aliases' with verb 'list' and description states it reads/retrieves command aliases from a configuration file (.todos/aliases.json). No modification, deletion, or execution occurs.
