List all plants in the FarmBot garden. Returns an array of plant points with their names, positions, and OpenFarm slugs. Use this to understand the current garden layout before planning operations.
AI agents call farmbot_list_plants to retrieve information from Farmbot Agent without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool queries and returns existing data about plants in the garden without modifying, deleting, or executing any operations. It is purely informational, used to understand garden state before planning. This is characteristic of Read category tools. Severity is low because unauthorized access to garden layout information poses minimal operational risk compared to hardware control or destructive actions.
From the tool's definition Tool name 'farmbot_list_plants' and description explicitly state 'List all plants' and 'Returns an array of plant points'. This is a retrieval operation with no side effects.
