Remove Area or Floor

ha_remove_area_or_floor
DestructiveIdempotent

Remove a Home Assistant area or floor to unassign entities, devices, or areas. Automations referencing them may break.

Instructions

Remove a Home Assistant area or floor.

Removing an area unassigns its entities and devices (the entities and devices themselves are not removed). Removing a floor unassigns its areas. May break automations referencing the removed area/floor.

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already indicate destructiveHint=true. The description adds valuable context: entities/devices are unassigned (not removed), floors unassign areas, and automations may break. This goes beyond annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Description is concise with no wasted words. Main purpose is front-loaded, followed by necessary details. Every sentence is informative.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity, presence of output schema, and annotations, the description is complete. It explains side effects, risks, and how to find IDs, meeting all needs for an agent to use correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so parameters are well-documented. The description adds a helpful hint for the id parameter: 'use ha_list_floors_areas to find IDs', which adds value beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it removes a Home Assistant area or floor, with specific verbs and resource. It distinguishes from sibling tools like ha_set_area_or_floor (create/update) and ha_list_floors_areas (list).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It says what the tool does but does not explicitly tell when not to use or recommend alternatives. It is clear for its intended use but lacks exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
