get_location

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

With no annotations, the description carries full burden for behavioral disclosure. It only states output (coordinates), but does not mention read-only nature, required permissions, rate limits, or error conditions. The implied read-only action is insufficient.

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 extremely concise (one phrase). While not verbose, it is too terse and lacks structure (e.g., no verb or complete sentence). It could benefit from a slightly fuller sentence without becoming long.

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?

Despite having an output schema (which may detail return format), the description misses other key context: no usage guidance, no parameter semantics, no behavioral traits. For a simple tool, more completeness is expected to ensure correct invocation.

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?

The description adds no meaning to the 'device_id' parameter. Schema coverage is 0%, and the description does not explain what device_id is or how it relates to the result. The agent gets no help understanding this required parameter.

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 'GPS coordinates of the device' directly states what the tool returns. It is clear and specific, though it lacks an explicit verb. The name 'get_location' reinforces the action. No confusion with siblings, which are mostly about settings or status.

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 'find_car' or 'list_devices'. No prerequisites or exclusions provided, leaving the agent to infer usage context.

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