nc_get_population_stats

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

No annotations are provided, so the description must carry the behavioral disclosure burden. The single sentence only states the basic read operation and gives no detail about default behavior, grouping, filtering, or return format. This is minimal transparency for a tool that offers optional parameters.

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 sentence with no filler, and it front-loads the core purpose and scope. It is appropriately concise, though it contains no additional structural elements like parameter or behavior highlights.

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?

With no annotations and no output schema, the description needs to provide more context about what the returned statistics look like and how parameters alter the result. The current text only states the data source and general subject, leaving an agent uncertain about response shape and tool behavior.

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 100%, with both parameters having clear descriptions in the schema: 'How to group results' and 'Filter by province'. The description adds no additional parameter context, so the baseline score applies.

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 a specific action ('Get') and resource ('population statistics from the 2019 census of New Caledonia'). It is distinct enough to know its subject matter, though it does not explicitly contrast it with sibling statistics tools like 'nc_get_job_seeker_stats' or 'nc_get_vehicle_stats'.

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 implies usage: call this when you need New Caledonia 2019 census population statistics. However, it does not provide any when-to-use versus alternatives guidance, nor does it mention the grouping/filtering options that could direct an agent to this tool over related ones.

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