entities_assign_entity_to_area

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

With no annotations provided, the description carries the full burden. It implies a mutation ('assign') but does not disclose side effects (e.g., overriding previous assignment, validation failure behavior, or whether it is idempotent).

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

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

Single sentence is concise and front-loaded, but minimalism sacrifices completeness. For a simple tool this may suffice, but more detail would improve clarity.

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

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

Given the tool's simplicity (2 params, no nested objects), the description omits return value (despite an output schema existing), error conditions, and prerequisites. Agent lacks confidence in correct usage.

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

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

Input schema has 0% description coverage. The description adds no meaning to the parameters 'entity_id' and 'area_id' beyond their names. An agent needs to guess acceptable formats or values.

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

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

The description clearly states the action 'assign' and the objects 'entity' and 'area', distinguishing it from siblings like 'areas_get_area_entities' (which reads) and 'entities_list_entities'. However, it does not add specific verb+resource precision.

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

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

No guidance on when to use this tool versus alternatives like 'areas_get_area_entities' or 'devices_list_devices_in_area'. No prerequisites (e.g., entity/area must exist) or exclusions are provided.

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