List all livestock for a specific farm.
AI agents call list_livestock_by_farm to retrieve information from Farm OS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

There are no side effects, data modifications, deletions, or external operations triggered. The blast radius of misuse is minimal—an agent could retrieve livestock data it shouldn't access, but cannot alter farm operations or cause harm.
From the tool's definition Tool name 'list_livestock_by_farm' and description 'List all livestock for a specific farm' indicate a retrieval operation with no data modification, deletion, or code execution.
