areas_get_area_entities

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

With no annotations provided, the description fully bears the burden of behavioral disclosure. It only states what the tool does, not how it behaves (e.g., return format, permissions, limits, whether it returns entities or their states). This is insufficient for safe and effective use.

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?

The description is a single, front-loaded sentence with no redundancy. However, it is so concise that it sacrifices necessary detail. A score of 4 reflects efficiency but notes that a bit more content would improve completeness without harming structure.

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 (one parameter, no nested objects) and the existence of an output schema, the description should at least clarify what 'entities' means (e.g., entity IDs, full states). It is incomplete because it omits the return type and any prerequisites, leaving ambiguity for the agent.

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?

Schema description coverage is 0%, meaning the parameter 'area_id' has no schema description. The tool description does not add any semantic context for this parameter (e.g., format, source, or relationship to other tools). This completely fails to compensate for the lack of schema-level documentation.

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 'Get all entities belonging to an area' is specific, using a clear verb ('Get') and resource ('entities belonging to an area'). It distinguishes itself from sibling tools like 'areas_list_devices' (only devices) and 'entities_list_entities' (all entities globally), making the tool's scope unambiguous.

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?

The description provides no guidance on when to use this tool versus alternatives. For example, it doesn't contrast with 'entities_list_entities' (global list) or mention prerequisite steps (e.g., needing a valid area_id). This lack of usage context leaves the agent without decision support.

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